Treestyletab: TST randomly turned grey, and reloaded itself, upon finishing that my entire tree structure was lost

[stapuft]

while a page was loading, TST randomly turned grey, and reloaded itself, upon finishing that my entire tree structure was lost, my tabs are still there, but they are all on the same level now.

are there any known causes or fixes for this? i have had vaguely similar issues for a while now, but this is the first time it has done it without firefox crashing.

windows 10, tst 3.0.11 ff 66.0.5

I am enabling debug mode but i dont know what good it will do now.

[stapuft]

oh great.......while trying to reorder them manually, they all disappeared.....

[stapuft]

oh great.......now tabs act like ghosts or something, they are there, but cannot be clicked on, right clicked on, moved or anything, I can CTRL+tab to them though, so they are still there....and I have restarted firefox 3 times already, I can move a few tabs, then this happens again.

[piroor]

"while a page was loading, TST randomly turned grey, and reloaded itself" it is triggered when TST detect mis-synchronization of tabs tracked by TST and Firefox's native tabs. The operation should keep tree structure as it can, but it may fail with some unknown reasons. I need a help to find out the trigger causing the mis-synchronization on your environment, and I cannot solve it without clear steps to reproduce...

[stapuft]

okay thank you, since this happened last, I have been running in debug mode, constantly, when/if this happens again, I can try my best to give steps to reproduce manually, but it seems to happen so randomly I cant determine actual triggers.

when/if this happens again, what do you need from me, exactly, so that this bug can be brought to light?
detailed instructions or a link to them would help immensely, is the pertinent information available on your wiki?

[stapuft]

@piroor also if you need so much specific information, why not have a "report a bug" thing that auto logs and emails you said debug info that you need? other extensions and even Firefox itself has this feature.

[piroor]

I agree that it is hard to narrow down conditions, but it is required. For example, recently I successfully found a complete conditions to reproduce a rare case bug #2267. As described at the issue, steps to reproduce may become very long sometimes when it happens rarely. I couldn't fix it for a long time, and when I meet it again I struggled digging out the conditions and finally did it.

"Report a bug" feature is sometimes effective, but sometimes not. Such information may help debugging of crash bugs, because in most cases the report can contain fully required information to debug the problem. On the other hand, problems like this issue are triggered with latent breakages caused by past operations, so sadly "detailed information when the problem appears" doesn't help debugging. Instead I need to know the operations to cause the latent breakage.

[stapuft]

@piroor well then I am afraid I can be of no help, as it happened again, and again it happened while I was not at my computer, I came back to my computer greeted by this

i restarted FF and the pinned tabs became normal again but none of my other tabs are where they should be.

tab Id 91 is right beside tab id 46... debug mode is on but....i cant tell whats wrong other than the tab order...

what should I do next, would a list of all my extensions and tweaks be pertinent to determining what the bug is? anything you could tell me you need that I can actually provide, and I will gladly do so.

the only way i can think to reproduce it would be to have over a hundred tabs open, to various sites, mainly 4 sites, (video streaming sites) but most of them hidden and suspended to save on ram usage. for well over 24 hours. and with my current luck it will randomly decide to crash while you are asleep so you have no idea what made the crash happen.

i dont know if its pertinent but i had multiple ghost tabs appear and i wasn't able to do normal things, like post this comment until after i restarted Firefox...again

[stapuft]

still no clue as to whats going on, FF has crashed many more times lately, after the lastest crash, before i restored my session, I remembered the TST automated tests, and ran it, it failed miserably.

these were my results.

......F..F.....Done.

testInheritContainerFromAutoAttachedParent

[piroor]

I've looked the list of installed addons. I think only "Hide Tabs" and "Move unloaded tabs for Tree Style Tab" may affect to TST's behavior. Could you try disabling them for a while to testing?

[piroor]

And, if the summary of this issue I updated is wrong, please correct it. If you think that the problem you met couldn't be summarized, I think you may still confused and you need to marshal the complex situation.

[stapuft]

ok i can do that, but how do I hide/suspend my tabs withought the hide tabs extension, I need to be able to do that, I have a shit amount of ram.

[piroor]

Other addons like "Auto Tab Discard" provides ability to unload tabs without hiding. It possibly helps you.

[stapuft]

okay thank you, is there anyway to emulate the behavior of the "Move unloaded tabs for Tree Style Tab" extension, without using said extension? its not necessary, but it pretty much goes back to normal Firefox behavior, ie you can drag tabs without the tabs you are dragging becoming active. unlike with vanilla TST which changes that default tab behavior.

[stapuft]

with those extensions disabled I haven't had any crashes yet, but it hasnt even been 24 hours yet, it failed its automated tests, but i am about to test if it will restore tabs properly by force closing firefox.

here are its test results

` ......F.....F..Done.

[stapuft]

EUREKA! it appears one of those two extensions was the culprit behind the tab order issue! if i experience it again ill update this thread but as of yet there haven't been any relapses.

[irvinm]

How about closing this issue and reopen it if you see it again? Glad you got it resolved.

[stapuft]

okay, I can do that.

[stapuft]

well it just happened again, more times than I could count in a row, without crashing firefox inbetween, after about the sixth time TST turned grey and reloaded itself, my structure was gone, the order appears to still be there, but all the structure is gone. and with the "move unloaded tabs" extension gone, to re order them will take FOREVER because TST changes the default firefox behavior and makes any tab you try to drag and drop, activate. is there any way to put Firefox back to its original settings in that regard...other than that extension that causes more problems than it solves?

[stapuft]

FUCK!!!!!~~!!!@!@!!@!

[irvinm]

@stapuft are you still seeing the issue with the current version of TST? It has been a while.

[irvinm]

@piroor I think you can close this one.

[Arthaey]

I'm not so sure this issue should be closed — I've seen this behavior in the past couple weeks. I also use the "Move unloaded tabs for Tree Style Tab".

I find the ability to manually unload & hide tabs indispensable to the way I like to browse, so I really hope we can get to the bottom of why the tree structure gets lost every now and then.

How can users help to debug this issue, given that it happens only occasionally (and randomly, so far as I can tell)?

[stapuft]

@stapuft are you still seeing the issue with the current version of TST? It has been a while.

no actually, i have had a few minor issues with TST, (like the color changing issue) and it will occasionaly crash on me, turning Grey, and reloading, but I haven't actually lost my tree structure in a while. so i am SUPER thankful for that.

what i have done, is i have disabled that extension, but havnt uninstalled it, so when i need to move loads of tabs, i quickly enable it, move the tabs, then disable it.

yeah its a bit of work, but it works.

[irvinm]

@stapuft what are your thoughts about closing this item at this point in time?

[irvinm]

@Arthaey or @stapuft ... can this item be closed now?

[Arthaey]

This still randomly happens to me several times a month, unfortunately.

[irvinm]

@Arthaey sorry to hear that. Thanks for the update.

[piroor]

To be honest I also see a problem similar to this a few times, but I've not clearfy the conditions to reproduce yet. I still seriously need concrete steps reproducing with 100% probability...

[piroor]

But I think there are some environment dependent conditions - CPU speed, RAM size, applications running aside Firefox, and more. So even if you reporter successfully narrow down "steps to reproduce", it may not effective on my environment.

Thus I hope that someone addon developer tries to inspect the problem deeply on his environment and creates a pull request...

[He4eT]

I had the same troubles.
Disabling of the "Optimize tree restoration with cache" checkbox solve the problem.

I Hope it will help you in your research.

[stapuft]

unfortunately, this just happened to me again, and has happened multiple times since originally making this post.

as for running programs, I only have Firefox, and "avast antivirus" running 90% of the time, my computer is rather slow, and so I tend to only run one program at a time, other than my antivirus. I would take a screenshot, but apparently you can't take a screenshot of task manager? wtf?

heres my basic pc info

just for examples sake, my messed up tab order again (all the reddit tabs should be under the "reddit" header, the GitHub tabs under "GitHub" etc etc)

[stapuft]

I had the same troubles.
Disabling of the "Optimize tree restoration with cache" checkbox solve the problem.

I Hope it will help you in your research.

I just tried this myself, will be testing to see if it works.

[Arthaey]

I've also unchecked "Optimize tree restoration with cache" to see if that helps me!

[irvinm]

Any updates @stapuft or @Arthaey?

[Arthaey]

Still crashes/refreshes for me, but I haven't seen it lose the tree structure in a while now…

[Arthaey]

It started crashing & messing up the tree structure a _lot_ more (multiple times a day again) recently. :(

Firefox 72.0b5 (developer edition)

[piroor]

Sadly I cannot fix this because this doesn't happen on my environment and it is impossible to inspect what's happen on your environment by me remotely. I seriously need a help by a developer who can debug TST itself by their own environment.

[Nexen23]

Seems I have same problem. TST looks grayish and if I try to collapse any tree, strange things happen (either tabs will overlap or nothing happens or few tabs will overlap while other don't collapse e.t.c.)

[davidmbesonen]

@Nexen23 What OS (exact version number), Firefox version, and TST version?

[Nexen23]

@davidmbesonen it seems problem was connected with the other one: https://github.com/piroor/treestyletab/issues/2517
I don't know why, but after a few hours of try-and-error to get tst cache cleaned Nth attempt to reimport scripts&styles finally worked and everything was fixed.

[irvinm]

@piroor I think you could close this as inactive.

[irvinm]

@piroor maybe just a friendly reminder.

[piroor]

I've seen similar problem recently on my environment. It looked to be triggered by something stucking on the extension process (please note that Firefox separates its processes for each purpose.) But there are too many possible reasons for me, for example my another addon "Text Link" sometimes triggers a slow script alert when a text is selected in a large webpage like Twitter.

Moreover, I've seen unknown freezings frequently after resuming of my laptop PC. It looks to be triggerd around text input, so it possibly be related to another serious problem around low level layers. The only one way to solve it is restarting of Firefox itself for me.

Both cases looked unrelated to TST for me. I agree that TST is almost slow and sometimes stucking is reported, but I think most cases are reprodusible with certain steps around operations on TST's sidebar. Both typing texts and operating text selection won't trigger something in TST, so I think they never hit TST's unidentified bug...

When you all watchers on this issue see freezing of TST's sidebar, could you investigate about other addons on your environment? If you see another addon is also stucked, killing the extension process may be the only one way to stop the freezing and you may need to restart Firefox itself.

[irvinm]

Thanks for the honest feedback @piroor. Hopefully with people continuing to watch out for this situation we can track down a process to reproduce it and then get it resolved.

[irvinm]

It has been 4 months ... are people still seeing this issue periodically?

[piroor]

Now I close this as outdated.
