[Desktop-packages] [Bug 1983010]
The tab doesn't completely lock up in this case - media continues to play audibly, and keyboard input is possible within the browser -- although invisible -- until the window and tab are visually obscured and then re-opened. In other words: after the issue appears, switching to a separate application and back again permits a single frame of the browser contents to render, but after that point they remain visually static (until the next manual refresh occurs). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1983010 Title: Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index2/size Status in Mozilla Firefox: New Status in firefox package in Ubuntu: New Bug description: I use Firefox Beta and launch it from the terminal.

Ok, this happened to me again a few moments ago while browsing GitHub, and this time Spotify web player was not open (so my apologies for mistaking that as the possible cause). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1983010 Title: Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index2/size Status in Mozilla Firefox: New Status in firefox package in Ubuntu: New Bug description: I use Firefox Beta and launch it from the terminal.

Hi Gian-Carlo - this is on Debian 11 (bullseye), using the Intel i965 VA-API driver (and media.ffmpeg.vaapi.enabled=false in Firefox, if that's relevant). I'm not super keen to attempt repro without the sandboxing in place at the moment but I'll add details if & when I do. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1983010 Title: Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index2/size Status in Mozilla Firefox: New Status in firefox package in Ubuntu: New Bug description: I use Firefox Beta and launch it from the terminal.
