Tampermonkey: [Firefox] Export to zip/file/cloud not working and breaking FF

[rayman89]

When using the export to zip/file/cloud feature there is a loading counter that gets stuck at either 97% or 100% and nothing happens. If I close the tampermonkey tab then firefox breaks not being able to load urls on any tab or open new tabs which requires restarting the browser to fix.

What Firefox version do you use?

[rayman89]

Firefox 56 x64 release on windows 7

I tested disabling all addons but tampermonkey the same issue occurs here is the browser console probably has to do with the number of scripts installed ( I have 44 scripts installed) because I tested on an other profile with 1 script and it worked.

Here is the browser console log

File export is also broken for me, Tampermoney hangs on "Please wait..." and following error is logged in browser console.

Unchecked lastError value: Error: filename must not contain illegal characters ExtensionCommon.jsm:407

Zip and cloud export seems to work fine. I'm using Nightly 58.0a1 and TM 4.5.5570beta (Oct 6, 2017)

This should be fixed at the dev channel.

Edit: ... and also at the most recent stable version: 4.5.5564. I'll double check this.

I've tested this with Ubuntu 16.04, Windows 10, MacOS Sierra and FF 56, 57 and 58. I can not reproduce the problems.

@Keith94 This really should have been fixed since 4.5.5564. Are you sure, you're using a current version? If so, does a file save dialog appear? What is the proposed file name? Also, can you please check the "Download Mode" setting? Does it say "Browser API" or "Default"? What OS do you use?

@rayman89 Save to disk and cloud are working fine here. Can you please do me a favor and try at a new temporary profile?

[rayman89]

I can confirm the zip export failing is related to the number of scripts installed I tested different amounts of scripts 44, 39, 29, 19, 3, 1 and all failed except 19 and lower. Those low amounts worked properly ONLY when using export to zip when using file export it got stuck at "please wait" and the export to cloud got stuck at "One drive..." and then the browser hanged. I also tested 20 and it took very long time but at the end the zip export worked. On my 3rd post I posted the browser and web consoles log.

The test was done on a new clean profile; only tampermonkey 4.5.5564 installed. Installed 44 random scripts from greasyfork on windows 7 x64 firefox 56 x64 and then started to delete scripts to test with different amounts and got the results explained before.

When working the zip file name was "tampermonkey-backup-firefox-2017-10-10T15-55-38.876Z.zip"

Also tested the dev version of tampermonkey on my normal profile with the same results with 44 scripts installed.

@derjanb

Are you sure, you're using a current version?

I switched to 4.5.5564 stable now

If so, does a file save dialog appear?

No. It says "operation completed" but no save dialog.

Does it say "Browser API" or "Default"?

Default.

What OS do you use?

Windows 8 64-bit.

I continued testing and If I press on export zip file and leave it for like 10 mins or so without touching anything on firefox the export zip function completes properly but it shoulndt take hat long and make firefox crash if you try to use it IMO.

Just want to confirm this bug. FF56.0.2 TM4.5.5584beta as well as the latest regular release. Every export option breaks Firefox.

[derjanb]

Fixed at 4.5.5590beta.

[rayman89]

Tested works properly.
