Hello everyone,

Why some Wikipedia pages cannot activate reading mode under Debian 12 and Firefox ESR 115.9.1, for example this English Wikipedia page on Emmabuntüs does not allow reading mode to be activated while French, Spanish and German pages can ?

See our test video on this subject: http://share.emmabuntus.org/Accessibility/Firefox_mode_lecture_non_disponible_emmabuntus_en.mp4

Is there a utility to test pages compatible with reading mode?

Or otherwise in which Firefox log file to see if a page is compatible or not?

Thanks in advance for your help.

I just got a chromebook! Details:

Device name: Lenovo Flex 3 12.2" chromebook, 8GB ram. Intel N100 Device code name: IP Flex 3 CB 12 (pujjo, version 123.15786.0) Firefox version: 124.0.2 (flatpak) OS version: Version 123.0.6312.112 (Official Build) (64-bit) Chrome: Version 123.0.6312.112 (Official Build) (64-bit)

When I watch a youtube video with chrome my cpu usage is 20-30% When I do the same with firefox my cpu usage is 50%

Running `about:support` and going into `webrender_compositor` I get the following errors under `env`: 1. Blocklisted by gfxInfo 2. Blocklisted; failure code 3. FEATURE_FAILURE_WEBRENDER_COMPOSITOR_DISABLED

I have set almost all these force renders = True and even granted gpu access to firefox flathub but still no difference in performance. I am asking now because I am just going in circles in the rabbit hole.

i am using firefox developer edition version 126.0b3 (64-bit) on linux mint with an x11 desktop and for some reason the drag and drop breaks frequently.

i think i have figured out how i can consistently recreate the bug as well as sort of fix it temporarily.

i start with a newly launched browser. everything works fine. but then if i attempt to drag and drop something shortly after i drag and dropped something else and it did the little animation where it returns to its original position, i find that i cant drag and drop anything FROM firefox to anywhere else. and i also cannot rearrage tabs.

it seems to fix itself whenever I drag something from another program TO firefox successfully such as text into a textbox, or a .html file into the window to view it.

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

When I run firefox on WSL2, buttons dont work on any pop up windows. Foe example when installing a firefox extention - it will download and pop up a small window at the top right to add the extentionto firefox. The buttons dont work. Another example is when opening up the firefox menu bar (hamburger bar) - it will pup up a small window to allow to open up settings, go to add ons, open bookmarks or history. The buttons dont work. Last example is the pop up window for this Ash your question page for firefox support - When clicking "Which topic best described your question - it will pop up a small window to select what type of question Im gonna ask. The buttons dont work.

I dont know how to fix this. I restarted, deleted my firefox profile, started of safe mode, nothing worked. How do I solve this issue?
