I can NO LONGER reproduce this issue with the new treestyletab-we-debug.xpi of comment#21 :)

Any way, the log :

I found a workaround

  1. Enable debug mode
  2. Disable "Optimize tree restoration with cache"
  3. Disable and re-enable addon. Tree loads (slowly, but loads).
  4. Enable "Optimize tree restoration with cache" again
  5. Restart addon
  6. Tree stops loading

So I'm able to reproduce the broken state in my profile.

When I start with a clean profile, TST loads normally.

The startup tab can triggers fatal error on the initialization process. I've introduced some more fixes about this problem on TST 2.4.6.

piroor picture piroor on 26 Jan 2018

I tried it with 2.4.6 and the problem persists - if I have "Optimize tree restoration with cache" enabled, after restart of FF it doesn't load the sidebar. I disabled it again.

I have the same issue with TST 2.4.6 in FF 57.0.4. @ksulli's workaround works for me: with the disabled option, the tree loads. I can update to FF 58 this evening and give you an update.

I am on FF 58.0 now and the problem is gone :)

(I re-enabled the above mentioned cache option, disabled debug, restarted FF)

blipp picture blipp on 27 Jan 2018

Hello, I have this problem since the FF 58.0 update: tab bar displays the "loading" icon forever.
I have 3 windows open. Windows 10 here btw.

kindofbeard picture kindofbeard on 28 Jan 2018

Same problem here, problem started with TST 2.4.5 and is still there with version 2.4.6 and FF Developer edition. I reverted to TST 2.4.3 in the meantime.

EDIT: With TST 2.4.6, I confirm that enabling debug mode and disabling the aforementioned optimization, followed by disabling the addon and re-enabling it works as a workaround for now.

zertrin picture zertrin on 28 Jan 2018

also seeing this with TST 2.4.6 and FF 58 on ubuntu. ksull's workaround also works for me. Guess that means there's a bug in the caching system? I do have like 200 tabs open in one window and 1000 in another. In another profile, I do not see a problem

jsams picture jsams on 28 Jan 2018

To all: Could you try to reproduce the problem with enabled "Debug mode" checkbox? In the debug mode you'll see detailed logs like https://github.com/piroor/treestyletab/issues/1742#issuecomment-361172325 in the debugger window. (How to start debugger for TST)

@ksulli Thanks a lot! Your log really helped me. I think recent commits should fix this problem.

@piroor i retested with the new version it looks like it's fixed, tabs seem to be restored correctly even when chache restore is enabled

ksulli picture ksulli on 30 Jan 2018

Unfortunately I am still seeing this issue. Freshly restarted Firefox so it's fully up to date as of today (13 May.)

Crell picture Crell on 13 May 2018

This problem only seems to happen if I have extensions.webextensions.remote set to true on my side.

tkhquang picture tkhquang on 17 May 2018

For all people still see this problem: could you cooperate to research what happens when the "infinite loading" happens? Steps to research:

  1. Start addon debugger and attach debugger for the "/sidebar/sidebar.html" page.
    Instructions: https://github.com/piroor/treestyletab/wiki/How-to-inspect-tree-of-tabs#how-to-inspect-the-sidebar
  2. Choose "Console" tab in the remote debugger.
  3. Focus to the command line at the bottom of the debugger window, and run gMetricsData.toString().

The last step reports a details of the initialization process successfully. If the sidebar is correctly loaded, the log will be:

total 2600 msec for 57 tabs
0: Loaded
632: init start
247: browser.tabs.query, configs.$loaded
570: applyStyle, waitUntilBackgroundIsReady and retrieveAllContextualIdentities
1: getEffectiveWindowCache start
12: (async) calculateDefaultSizes
5: (async) initializing contextual identities
2: (async) tabContextMenu.init
289: (async) getting kWINDOW_STATE_SCROLL_POSITION
396: getEffectiveWindowCache get {"cache":false}
6: getEffectiveWindowCache fail
402: (async) read cached sidebar contents
392: (async) getting registered addons and scroll lock state
153: rebuildAll (from scratch)
471: inheritTreeStructure: kCOMMAND_PULL_TREE_STRUCTURE
1: applyTreeStructureToTabs: start
0: applyTreeStructureToTabs: preparation
27: applyTreeStructureToTabs: attach/detach
11: applyTreeStructureToTabs: collapse/expand
1: inheritTreeStructure: applyTreeStructureToTabs
509: (async) inheritTreeStructure
0: start to listen events
49: apply configs
1117: (async) main
1103: (async) parallel initialization tasks
5: applying scroll position
30: init end

On the other hand, on such "infinite loading" case, the result will become too short and some part will be missing. So it helps me knowing what process failed on the case.

piroor picture piroor on 29 May 2018

On sidebar loading success, with tree restoration with cache disabled, I see gMetricsData.toString() output the above. On failure, when the cache optimization is enabled, I get the following:

total 1111 msec for 0 tabs
0: Loaded
894: init start
217: browser.tabs.query, configs.$loaded

The output is the same for all seven of my opened window's sidebars.

Note that I cannot consistently reproduce the behaviour. This time, on startup with optimization enabled everything worked fine. I then disabled it and reenabled the option, toggling the extension on and off to ensure reloading) and the problem showed. Repeated toggling showed “infinite loading” one time after another, but after restarting Firefox I am not getting the problem to show up again.

gonhidi picture gonhidi on 29 May 2018

@gonhidi Thanks a lot! I've realized that the initialization process is seems failed on very earlier step. It is completely unexpected result, so I deeply review initialization codes and found some dangerous cases. Could you collect debug log with the special build?:
https://piro.sakura.ne.jp/xul/xpi/nightly/treestyletab-we-debug.xpi

This build extremely report detailed logs around initialization. Here is instructions to collect debug logs, and please note that you need to activate "Debug mode":
https://github.com/piroor/treestyletab/wiki/How-to-inspect-tree-of-tabs#how-to-collect-debug-logs-of-tst

piroor picture piroor on 29 May 2018

Hi, I came from https://bugzilla.mozilla.org/show_bug.cgi?id=1460607#c20 ,

Since it is necessary to restart the browser in order to reproduce the problem.
How can I get the debug log from startup of Browser?

alice0775 picture alice0775 on 29 May 2018

Today the problem is back for me too (TST 2.4.21, FF 60.0.1), i tried installing the xpi with debug, but I need a development / nightly build of FF for that?

ksulli picture ksulli on 29 May 2018

I've just come across this bug trying to restore my session with 10 000 tabs. Successfully fixed it by deleting C:UsersusernameAppDataLocalMozillaFirefoxProfiles folder.

Please note that this is not the folder where Firefox stores its profile data: all profile data is stored in ..AppData Roaming

If you are afraid to delete this folder, just rename it.

I installed FF Developer edition, installed the debug version of the extension, but I wasn't able to reproduce the problem. After going back to "normal" firefox, and reinstalling 2.4.21, I also stopped being able to reproduce the problem.

ksulli picture ksulli on 29 May 2018

On nightly 62.0a1 (2018-05-28) x64 i managed to reproduce the problem only on 10th time or something with debug build with turned on debug in settings, but cannot catch logs from startup too, if that matters

RanHum picture RanHum on 29 May 2018

@alice0775 Sorry that I forgot to take care of Browser's startup process. I've updated the debug build: https://piro.sakura.ne.jp/xul/xpi/nightly/treestyletab-we-debug.xpi and now you can see recent 1000 logs after startup process. On the remote debugger, please select the namespace /sidebar/sidebar.html?... and type log.logs.join('\n'), then stored logs will be printed.

piroor picture piroor on 29 May 2018

@ksulli You need to use Nightly or Firefox Developer Edition (aka Aurora, not Beta), and you also need to turn a secret preference xpinstall.signatures.required to false via about:config.

@alice0775 @RanHum Thanks a lot, now I've got what is the problem. TST waits forever on this line on your environment:
https://github.com/piroor/webextensions-lib-configs/blob/5e0ec520447f0403379c14686487655cac8b3b8a/Configs.js#L105

piroor picture piroor on 29 May 2018 
 try {
   const lockedKeys = await browser.runtime.sendMessage({ type : 'Configs:request:locked' });
   this.$log('load: successfully synchronized locked state');
   return lockedKeys;
 }
 catch(e) {
   this.$log('load: failed to synchronize locked state: ', String(e));
 }

I expected that the promise returned by browser.runtime.sendMessage() is resolved or rejected immediately. However, actually the promise is not resolved and rejected, thus the await blocks all following operations.

piroor picture piroor on 29 May 2018

@piroor I have not yet managed to reproduce the problem once more, but hopefully the debug output would be the same that has already been shared. If I were to stumble upon the problem and see a different output I will share it. Thank you and good job for having found the likely culprit!

gonhidi picture gonhidi on 29 May 2018

I thought that this problem is caused by recursive await happening on edge case, so I've introduced a change to prevent such a recursion. https://github.com/piroor/webextensions-lib-configs/commit/280e1de1828712b9605febc1009252939f6634f4 And I've updated the debug build with the change. https://piro.sakura.ne.jp/xul/xpi/nightly/treestyletab-we-debug.xpi Could you try it and collect logs again? > all

Unfortunately I seem to have triggered the issue's symptoms with the current Tree Style Tab build, 2.4.23, both in the stable and the nightly Firefox, running on macOS. Going back to the latest debug build provided here (MD5: 62c38b3d63eb6dcbb0b18931e916113b) I got the following output when running log.logs.join('\n') from the remote extension debugger for any selected sidebar after disabling and reenabling the extension:

For some reason, on subsequent disable-enable-log.logs.join('n') tries (only a couple of them) I only seemed to get as output the last lines, from one of the tst<Sidebar-?>: l10s: apply ({}) onwards.

@gonhidi Could you add result of https://github.com/piroor/treestyletab/issues/1735#issuecomment-392656263 also?

piroor picture piroor on 2 Jun 2018

@piroor

The log.logs.join('\n') being the same as reported, the result of gMetricsData.toString() is the following:

"total 807 msec for 0 tabs
0: Loaded
766: init start
41: browser.tabs.query, configs.$loaded"
Webconsole context has changed

The reason that I have taken long to reply is because I cannot trigger the issue consistently: since my last report I have only had it happen this one time. Restarting Firefox with the cache option unticked and then marking it back again might be a temporary way to get things back on track, as opposed to unloading and then reloading the extension instead of quitting, but it lacks testing and I might be remembering wrong.

So today / yesterday i was able to reproduce the issue again - FF Developer Edition 62.0b6 (64-bit) + TreeStyleTab [debug] 2.4.21. Also - I tried to install the extension while I already was in a broken state, hopefully capturing the initialization logs.

I tried disabling and re-enabling the debug extension again (this time with debug mode enabled in the settings) and re-attaching the debugger. The actual log in the console is huge (hundreds of "build tab for" lines), but i tried filtering out some stuff that looks interesting to me - theres a single error message. Also, someone posted a very similar looking log to https://pastebin.com/80MbbQJC which i found by googling the error message.

and this continues for my other windows.

At the end, there are multiple logs about configs storage and then there is a single error message

Webconsole context has changed

So, i tried adding debugging information to the suspect method:
```javascript
function updateWindowCache(aOwner, aKey, aValue) {
  if (!aOwner ||
      !getTabById(aOwner))
    return;
  if (aValue === undefined) {
    //return browser.sessions.removeWindowValue(aOwner, aKey);
    logForCache(`updateWindowCache: `, {
      aOwner: aOwner,
      aOwnerId: aOwner.id,  
      aKey:     aKey,
      aValue:   aValue
    })
    return browser.sessions.removeTabValue(aOwner.id, aKey);
  }
  else {
    //return browser.sessions.setWindowValue(aOwner, aKey, aValue);
    return browser.sessions.setTabValue(aOwner.id, aKey, aValue);
  }
}

Unfortunately, this required several restarts before I got it right, and the extension seems to have sorted itself out... and the log now looks completely different, instead of many hundreds of :build tab from scratch" messages, I'm now seeing instead messages like

@ksulli Thanks, but 2.4.21 is outdated so the problem can be solved in recent versions. Could you try with the latest development build?

piroor picture piroor on 11 Jul 2018

@piroor the problem started in 2.4.23 (production version), so i switched over to the FF debug edition and got the debug version freshly from https://piro.sakura.ne.jp/xul/xpi/nightly/treestyletab-we-debug.xpi (which is now returning a 404) and 2.4.21 was the version reported by the debug XPI.

I see that 2.4.24 of the production build was updated yesterday.... so i'll wait if the problem appears again.

ksulli picture ksulli on 11 Jul 2018

I am on 2.4.24 and still encountering this problem.

Running 62.0 (64-bit) in Windows 10 and its still a problem =(

I have a feeling that this problem appears basically after every FF update - yesterday I restarted the browser, noticed it got updated and the problem reappeared (basically the whole browser is frozen). After a few restarts it somehow sorts itself out, rebuilds the tree cache and then its hard to reproduce until the next FF update.

I've tried updating of Firefox itself with following steps, but I couldn't reproduce this problem:

  1. Install Firefox 63.0.3.
  2. Start Firefox with clean profile.
  3. Install TST 2.6.8.
  4. Open "About" dialog and update Firefox to 64.0.
  5. Restart Firefox.

I tried with just few tabs, so I think that some opened (long-live) tabs or the total number of tabs on your environment may be a part of the conditions to reproduce the probelm.

piroor picture piroor on 11 Dec 2018

I am facing this issue intermittently on
TST 3.0.5
FF 66.0.1
Arch x86_64
I have 2 windows with ~50 tabs and an oldish FF profile.

Disabling and reenabling fixes the issue for some time.

I will try to catch debug logs if it happens again and post.

P.S. Thanks for the awesome addon! :)

@khushman1 This thread is old, and there is another active one #2200. Could you join to there? Steps to collect debug information is: https://github.com/piroor/treestyletab/issues/2200#issuecomment-476960598

I close this because outdated.
