No matter what I try, I can't allow any sites to present my screen or a window, I can't find an option in settings neither in the option to allow in the tab. The "allow" button is simply not available at all. How do I solve that? The problem happens in all sites that I've tried: focusmate, cofocus, discord, google meet, etc

This bug occurs very randomly, but it seems there have few things in common.

- Occurring on domain level, one domain at once. For example, if Youtube.com stuck, any sub address including each video page is not loaded. Other website and whole browser works fine. - Other program on same PC is not affected, too. - Which page is stop loading is completely random. It might be happen only on a popular, feature-rich site like amazon, google, but not sure. - The timing is also random. Maybe after waking PC up from sleep, but not sure. Frequency of occurrence is once every 1~5 days. - The workaround without restarting browser is 1.)switching to other container tabs(strangely), 2.)opening website on private window. Disabling all the addon manually didn't help.

Since it's randomness, I didn't have any logs about this issue.

Am I understanding this correctly?

HTML backup (bookmarks) doesn't support tags and annotations, but JSON backup does, and JSON backup doesn't preserve the website favicons, but HTML backup does?  

So, what I can do, is restore my (saved) bookmarks using JSON backup, then restore the HTML backup, this would get my tags and annotations, and the website favicons back? But the downside, I will need to remove duplicates?

Please enable the ability to use the "Dark Reader" add-on on this site or let us change it in the settings. Horrible experience in light mode. On the added image you can see that the "Dark Reader" add-on is enabled.

I have noticed for awhile now that when I load my Firefox homepage its keeps taking longer, certainly longer than it used to take. Also, when I load a You-tube video it takes about a minute for things to work properly. The video and audio are erratic and skipping and simply disjointed for about the first minute, but then after that period of time the You-tube video runs OK, both audio and video. Something seems to be causing those problems recently that I didn't have previously. The problem seems to just keep getting worse also. I would appreciate any input and suggestions that may help the problem. Thank you.

Hey, since 2 months firefox started crashing when a video comes to the end. I tried it in troubleshoot mode skipped to min 10:45/10:50 and played. after this 5 sec it just crashed. I noticed it on youtube but tried it on other players and it also happened. Today I also started a video on a other website and it crashed but not when starting youtube videos.

Here my last 5 crash reports: bp-8fdedc8b-c8bc-404f-9e3e-8f2fd0230813 bp-b15becdb-456b-4a22-971c-2c0c20230813 bp-9754361a-f67b-445a-9163-c88a20230813 bp-cffc46ae-9ae5-4678-a323-7b60b0230813 bp-a863679a-577e-45f4-9f4e-002bc0230810

Best regards, Michal

my firefox youtube is broken, every time i close firefox, and open youtube, the comments and the sidabar wont load, until i clear my cookies and login. so that fixes it, but its not permanent. if i close or restart firefox, id have to repeat this process again. and yes, ive disabled all my extentions and cleared cache. and updated firefox.

Hi everyone, I am currently using Firefox "112.0.1 (64-bit)" on Windows 10 "10.0.19045 Build 19045]"

I have problems using almost all Google websites: most of the times they do not load at first attempt, and when they do they do not works properly. As example: Youtube does not load (or the cached version says that there is no internet connection), then after a few attempts it loads but all thumbnails on the home are gray.

On another browser (Edge) all websites works normally.

Using private window has the same problem, I have no extension and no plugin other than OpenH264 Video Codec provided by Cisco Systems, Inc. and Widevine Content Decryption Module provided by Google Inc.. I tried emptying cache and also reinstalling Firefox.

The only fix I found on the web is to disable hardware acceleration from settings. If I disable it and restart the browser, then all websites works normally. Actually I can't see this as fix but as a workaround, since I am using a notebook and I'd like to use my GPU for video decoding and save energy.

Maybe I am missing something? Is there something I can do? Thanks.

I'm using freshly-downloaded Firefox version 102.2 on a brand new laptop (Windows 11 Pro version 21H2), and every single extension is showing a "Installation aborted because the add-on appears to be corrupt" message when I try to install. I have tried checking for updates, quitting and reopening firefox, restarting my computer, refreshing firefox, uninstalling and reinstalling firefox, as well as any and all combinations of those. I've scoured these message boards and nothing is working for me. Please help!

I use Iosevka font as my preferred custom font for websites, I really like this Firefox feature (actually one of the main reasons why I swapped from Chromium browsers), and as of updating my Firefox Nightly to "Nightly 119.0a1 (20230908094535)" version this feature no longer works on all websites, and only seems to work on the search bar when I open a new tab.

Image 1: Settings (unchanged since previous version when this feature worked) Image 2: Search bar in new tab is using Iosevka font correctly Image 3: An example of another website where the font is not being loaded where it did in the previous version.

Thanks.
