Firefox Support Forum

After I have started the computer and have opened the Firefox Developer Edition, there is no website content visible - everything is transparent. Links are clickable and context menu opens up, but the content is just transparent (screenshot attached).

When I close & repone the firefox, then usually on 5th to 10th attempt everything starts working until next reboot.

Firefox(Default edition v94.0) is working just fine with no problems on same machine.

When I first noticed this, version was 95.0b3. Now I'm on 95.0b12.

OS is Xubuntu 21.10 and hardware is HP ZBook Power G8 - i5-11400H, Nvida Quadro T600.

I've already tried: 1) opening on safe mode, 2) reinstalling using Ubuntu's "umake" commant line tool, 3) reinstalled by downloading it from https://download.mozilla.org/?product=firefox-devedition-latest-ssl&os=linux64&lang=en-US and copying the files, 4) opening computer using both Nvida's and Intel's built-in gpu

but nothing have worked so far - still the issue persists.

Is there anything else I should try?

Thanks!

Firefox has become very slow for some two weeks om my desktop with Linux Xubuntu 18.04. Some sites can be approached without problems except for the speed, other sites are opened after some time, but freeze so that scrolling and clicking on links won't work. I tried to find an answer in the Settings......

I deinstalled firefox 98 completely from my Xubuntu 20.04.4 I then deleted all firefox related things from ~/.cache and ~/.config I rebooted I newly installed Firefox 98 from repository. Firefox 98 still does not produce sounds. Even a local file:///home/rp/Music/testfile.mp3 runs but does not produce audio output (it worked fine in Firefox 97). The Volume display is showing max. value. Firefox is even visible as stream in sound system's Volume Control / Playback (when the mp3 file is running) with 100% On my system, audio works fine with chromium browser as well as all other audio apps - as before. The earlier release Firefox 97 ran fine and produced audio output as it should. Firefox 98 currently runs without additional add-ons (no one installed besides the default Open H264 Video Codec).

What can I do to get Firefox 98 to output sound?

Hello

I want to open pdfs from firefox (snap 101.0.1) with the default application of the system (Xubuntu 22.04) and not open them in a new tab within forefox.

But it does not work, as if there was a problem with the system handler but only for pdfs and not for other file formats.

More details :

• I changed Preferences/general/Applications for pdfs to use either "always ask" (and then chose "open" " With system handler" when asked) or "default system application". In both cases the pdf is downloaded but not opened. If I right click on the downloaded pdf in the list of downloaded files and then chose "open with system handler", nothing happens.
• Opening the pdf inside Firefox works well and opening pdfs saved on my disk (outside firefox) as well.
• Opening other file format by choosing to open them from firefox with the system handler works well too (tested eg with .torrent, .xls, .tif,...).
• I tried to change the default system application for pdf (Atril) to other softwares without success (Okular, Evince).
• If I try to open a .djvu file with the "system handler" it is opened correctly using Atril which is the also default for pdfs... So Atril works for .djvu files but not for pdfs...
• I tried to replace the handlers.json file from my profile by a handler.json file from a brand new profile, without success (I still have a backup of my old profile file if needed). I did that because opening with the system application worked before and the bug appeared after I changed all applications preferences to "always ask" (and there were a lot of them in my rather old handlers.json file).

I'm lost...
