Diễn đàn hỗ trợ Firefox

Hi I am using Firefox on Debian 10, and it just plays audio to the pulseaudio server to the right channel. No idea why. Other applications are serving audio in stereo. Any other reports of this or fix?

FireFox 102.6.0esr on Debian 11 with a 5.10.0-20-amd64 kernel. (http://security.debian.org/debian-security stable-security/main amd64 firefox-esr amd64 102.6.0esr-1~deb11u1 )

My problem initially started out on a profile migrated from Windows (with some extensions installed), but Ive reproduced from a brand-new profile. Similar to https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can

Although the problem is sporadic, it occurs more way frequently than I would like. I have done quite a bit of troubleshooting with different profiles, used the --profile flag, sometimes --safe-mode, sometimes called around strace -- the results are pretty much the same.

Launch FF (as a new profile), and it will display the two tabs:

• tab 1: "FireFox starts here" image of Soraya Osorio.
• tab 2: https://www.mozilla.org/en-US/privacy/firefox/

Sometimes I am able to load in an additional website (which is short-lived), but ultimately traffic peters out and tabs are just spinning endlessly. No network timeouts. Firefox's just waiting on ... something.

Other times, when loading the profile with extensions enabled (NoScript, Multi-Containers, etc), clicking on a extension's drop-down menu (eg: Multi-Containers) it's not a full rendered drop-down but instead a thin (~2px) vertical line.

Errors from commandline:

• Missing chrome or resource URL: resource://gre/modules/UpdateListener.jsm
• Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs

(The clean up of FireFox on normal quit can take up to 30 seconds)

When wrapped in strace I see ridiculous amounts of

• recvmsg(4, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable)

interspersed with

• recvmsg(4, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\16\0y\n+\0`\1\0\0>\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\

0\0\0\0\1\2z\n\0\0\0\0,\0`\1\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0},

0) = 64

Im not sure why this occurs with only FireFox. Ive ran instances SeaMonkey, Pale Moon, WaterFox, Epiphany, Google Chrome, Brave and Vivaldi without seeing these issues.

I highly suspect there's a conflict with something else I run. Already disabled fail2ban and apparmor. Are there any system calls from the strace that I should look for?

If Firefox is already running, opening a link in a new window from outside of Firefox will launch the new window and open the URL however the new window will not get focus.

This is easy to reproduce by starting Firefox and then from a terminal running `firefox --new-window` or `xdg-open http://`.

I believe this is a bug as it is inconsistent with the behaviour of:

• Opening a new window from within Firefox (new window gets focus)
• Opening a new window when Firefox is not running (Firefox window gets focus)
• Opening a link in a new tab when Firefox is running `firefox --new-tab https://bbc.co.uk` or `firefox https://bbc.co.uk` (existing window with the new tab gets focus)

Tested on Debian Linux using Firefox 112.0.1 (AMD64).
