I encountered a Problem since the last update. When watching a Video on Youtube, the Playback is flashing, especially on green and red colors. I did see some People mention a similar issue years ago, so I followed the same troubleshooting by disabling Hardware acceleration and all extension. The Issue keeps persisting I am browsing on a M1 Macbook Air - no other Browser on my System has that issue. Here is an example with Screengrab https://imgur.com/a/EFrzzAD

When clicking a web link from the "Finder" (and Firefox is inactive/closed) a blank google search page opens. If Firefox is already open the desired link will open

Hello,

I had to deactivate 2FA briefly, and then attempted to use a reactivate it again. I am able to scan a QR, but when I try to enter the OTP codes that show up, I receive the following message "Incorrect two-step authentication code". This has happened with Raivo and Authy (the previous 2FA app). What is causing this?

When I go to certain web sites, (Xfinity, Blue Cross Blue Shield), a message pops up saying, "This page is slowing down Fire Fox. To speed up your browser, stop this page". When I go into Safe Mode, I can get to those sites. How can I get rid of this message/problem? Fire Fox has current update as does my Mac.

Every time I open a video on a website and try and enter fullscreen mode, it never lets me exit fullscreen mode. Then I have to close the entire window. Also, sometimes I have to refresh the page once or twice to even get in to fullscreen mode. Google is only showing me stuff about Firefox fullscreen mode, NOT fullscreen mode for videos, which is the actual problem.

After upgrading to the latest version (112.0.1) on MacOS 10.15.7, the bookmarks toolbar disappears when I enter fullscreen mode ('Always Show' is selected under Bookmarks Toolbar in the View menu). When I exit fullscreen mode, the toolbar reappears but a large grey bar then appears at the top of the window (see screenshot). I've read answers in the knowledge base that suggest that the toolbar always disappears in fullscreen mode, but I am 100% sure that this behaviour did not exist before the recent upgrade (perhaps this behaviour has been around for a while in Windows?). Either way the grey bar is clearly a bug and feels related to the toolbar behaviour. Has anyone else experienced this?

Every time I try to login to a different page my firefox crashes.

I also did get the attached message, wasn't forsure if this was apart of the issue?

I have tried to dump the preferences, clear cache, restart, clear history.

As of a week or two ago I can no longer save URLs to bookmarks folders in my bookmarks toolbar. I can drag and drop it but nothing happens, does not save in that folder. Neither can I save a URL via clicking on the star then choosing a folder. Doesn't stick in the folder. How can I fix this.

Hey there, I was using one of my macs today and it suddenly started updating. It was taking ages and seemingly stalled, so I closed the app.

Now, all our bookmarks and history is gone. Also, the now updated version is not showing my new history etc.

Is there any way to retrieve our original bookmarks, history and passwords?

Firefox gives the following message on screens where news sites want to show for example a news clip "THEOplayer workers could not be loaded. Please check that the worker's version matches THEOplayer's version 5.1.0". Can this be solved? Or do I need to use Chrome instead?

Example of a place this happens https://www.expressen.se/tv/nyheter/miljogruppen-far-smaka-egen-medicin-igen-/

As described in the title, any form of video playback on any website will randomly dim almost like autobrightness for video playback. This has nothing to do with auto brightness etc because I have this turned off in my device settings as well as the only affected region of my screen being the part that is playing video. This does not happen on any other browser.

tldr when using firefox something keeps dimming my video and i don't know how to turn it off.

Recently, my FireFox has been acting a bit strange when it comes to playing videos. I am using a site called Udemy to watch a video course I'm taking, however, the videos don't seem to play for either a long time, or until I tab into YouTube and play a video there.

This issue is not only with Udemy however, as the YouTube videos also take longer than normal to start playing; It's not only at the start of the video either (whilst waiting for the video to fully load), It's all the time, between every pause I have to wait around 3-4 seconds before It actually start playing.

The issue is clearly something to do with videos but I find it very strange that playing a YouTube video forces my Udemy video to load.

It's been a real struggle trying to get todays course day done, since every time I pause the video I end up having to wait a while or go to YouTube and play a video to make it continue.

I've gone through all the basic troubleshooting recommended for video issues on here and other places: Turn of hardware encoding, lower security levels, enabling autoplay etc etc; absolutely no luck. I've tried disabling extensions one by one, disabling themes, running FireFox in troubleshoot mode, clearing all data/history/cookies/cache, making sure DRM-controlled content is enabled as well as trying it disabled. You name it, I feel like I've tried it at this point... Any suggestions are highly appreciated!

Another thing to add is Chrome isn't having this issue, neither is Safari.

I'm a web developer working on an app running in Docker on my MacBook. Chrome, Edge and Safari trust the self-signed certificate that has been imported into the Mac's root certificate store and have no security issues, but when I try and access the web app, I'm hit with "Warning: Potential Security Risk Ahead" and the error code is MOZILLA_PKIX_ERROR_CA_CERT_USED_AS_END_ENTITY

I really miss Firefox, particularly the multi-account containers feature. What do I need to do so that Firefox will trust my certificate for my local web app?

When I enter a text in the address bar and press the 'return' key nothing happens given that all of these are true:

1. I'm connected to Mullvad VPN
2. I'm using Firefox
3. Address bar default search engine is set to 'Google'.

So to give some examples: 1. If I'm on chrome and everything else is the same as above, it works. 2. If I'm disconnected from the VPN, and on firefox, it works. 3. If I'm on VPN, and using firefox, but I set the default search engine to 'duck duck go' it works.

I tried all the steps in the troubleshooting guide here - https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems and none of them worked for me. I'm quite confused about the issue here.

What could be wrong here?

I'm attaching a screenshot of what happens when I type text and press 'return'. Literally nothing happens, not even a 'webpage loading spinner'. Also attaching screenshots of network settings.

If you need any other information that can help with the troubleshooting please let me know. Thank you for taking the time to help me!

I downloaded a app on my Macos Big Sur workstation (https://kevin-de-koninck.github.io/Clean-Me/) and I ran it (I did not have the option "User Preferences" Selected) Somehow, after rebooting my computer shortly after, it had logged me out of my Firefox account. That shouldn't be a big deal right? Somehow at the same time my Lastpass password program does not have that account saved in it. It has a secondary account ( that used to be the primary, but I guess I switched it at some point) that I can login to, however whenever I login to it, it says

No videos appear at all on Teachable, just a blank space where video should be. I have allowed video and audio (video and audio work on many other sites). I have cleared my cache. I have to use a different browser to use this site. I have also noticed other sites that have the same problem.

I hate twitter, yet all I have to do is touch the search bar and I see the fascist, vile 'X' suggested for me. I've tried everything and there's nothing that seems to get rid of it, like the vile roach that it is. It's like seeing a swastika every time I use the computer. Do I have to see it every day or can I get rid of it? Any help would be greatly appreciated! Not an 'X' fan, Tony
