Hello,

It is suspected that latest version of Firefox version 78.11.0esr (64-bit) is causing operathing systems to crash. I have not seen it on Windows platform as I am not using it. Platforms I am using are OSX and XUbuntu. The error occurs lingering on a site for a very long time. First it starts getting screen graphic errors like, some pixels are not being updated correctly. Then after a while screen starts to flicker, in a massive state, like the graphic processor is broken. In some cases with command key strokes one is able to kill Firefox, screen is back to normal and one can continue working. Facebook is the site that most commonly is causing error, but there are also other sites.

Wrong offset for the right-click menu → Right-click on link immediately opens link in new tab unless button is held (at least three years old bug)

Hi. There is this at least three years old GUI bug that is not yet fixed, I'm writing this post to show the temporary workaround and hopefully get more interest in the bug itself. This would be an urgent usability bug, but it's still here because probably not everyone can reproduce it.

Link to one of the bug reports: https://bugzilla.mozilla.org/show_bug.cgi?id=1504021


> Description

Removing the title bar doesn't set an offset for the right-click menu → the right-click menu will appear slightly wrong positioned, with its first entry below the mouse cursor → the first entry of the menu will get a mouse-release event and will trigger.

The effect of this can be different depending on what you right-click:

  • right-click some empty area in a web-page: you will be taken back to the previous page (because the first menu entry does that)
  • right-click a link: you will open the link in a new tab (because the first menu entry does that)


> Steps

  • Have a non-maximized Firefox window.
  • Disable the title bar (through the "Customize..." option)
  • Right-click anywhere on a webpage: you will be taken to the previous page.


> Workaround

Enable user styles by setting toolkit.legacyUserProfileCustomizations.stylesheets to true. Create "chrome" folder in your profile directory. Inside, create "userChrome.css", and write:

   #contentAreaContextMenu{ margin: 20px 0 0 20px }

Dear all,

I am having a severe issue using Firefox on Linux. That is when I use the browser to watch YouTube it is almost guaranteed that the entire system will hang, become unresponsive and then require a hard reset.

I'm using Xubuntu 19.04.

The laptop is a ThinkPad T450. It has a standard configuration except that I installed a SSD. I ran a comprehensive self-test using the Lenovo BIOS' testing feature and everything was given the all-clear. I note that the same problem doesn't occur on my preferred WebKit-derived browser which is Vivaldi.

I'm not the only owner of a T450 in my household. Curiously, this other T450 which runs Xubuntu 18.04 (LTS) does not manifest the same issue. This system also uses Firefox as its browser.

I was advised to check the system logfiles. The only mention of anything likely in the logfiles is the xsession-errors file:

(xfce4-panel:1291): xfce4-panel-CRITICAL **: 21:01:45.450: panel-window.c:2245 (panel_window_active_window_geometry_changed): expression 'WNCK_IS_WINDOW (active_window)' failed.

(/usr/lib/firefox/firefox:1631): dconf-WARNING **: 21:01:47.129: Unable to open /var/lib/snapd/desktop/dconf/profile/user: Permission denied [Child 1577, MediaDecoderStateMachine #1] WARNING: Decoder=7f15d3e94c00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::MozPromise<RefPtr&lt;mozilla::MediaTrackDemuxer::SamplesHolder&gt;, mozilla::MediaResult, true&gt; &gt; mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file /build/firefox-9JL5Vx/firefox-69.0+build2/dom/media/MediaDecoderStateMachine.cpp, line 3309 [Child 1577, MediaDecoderStateMachine #1] WARNING: Decoder=7f15d3e94c00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::MozPromise<RefPtr&lt;mozilla::MediaTrackDemuxer::SamplesHolder&gt;, mozilla::MediaResult, true&gt; &gt; mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file /build/firefox-9JL5Vx/firefox-69.0+build2/dom/media/MediaDecoderStateMachine.cpp, line 3309 </p>

Reference to my post on the Ubuntu forums: https://ubuntuforums.org/showthread.php?t=2426276

I'd greatly value any help to solve this issue. I'm willing to look at other logfiles or send over any additional information that might help diagnose this problem. Anything to help me get back to using my browser of choice!

Kind regards. Thran
