Hello,

Can not play YouTube videos anymore in current version from Firefox. Before this update (again not needed and messy one) they worked. The videos shown at home screen or recommendations on the YouTube website. Same for my subscriptions, current videos as videos I played earlier somewhere. The YouTube website shows their picture and then the "no content available" message. Refreshing that page and try sometime later, both do not solve this. Unknown why this is happen. It seems another "new" bug inside Firefox.

Lors de la mise à jour hier du logiciel Mozilla, ont disparu : - tous mes dossiers locaux (certains très importants) - tout mon carnet d'adresse - et mon agenda Impossible de les retrouver. Que puis-je faire ? Merci d'avance pour votre aide Cordialement Christine

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

I searched around DDG for awhile and didn't seem to find others with this issue. I have firefox-esr installed on another device and the optiion is still enabled over there. Is there a way I can gain that back on this install? I use it for every link I copy. Thanks

I do have an account to my passwords, history and so on simplify my work with Firefox. I did logon to firefox with a new instance on an Apple computer of a friend with my account. After my session, I did close this account again. Now I found out, that I got all his usernames and passwords. Does he have mine as well?

With the recent update, this horrible side bar thing has appeared and I've clicked every place I can find to get rid of it. Please advise how to lose it. Thanks.

I am reaching out to seek assistance with a recurring issue we are experiencing in the Mozilla Firefox browser.

Issue Description: On the user's first visit to the page, the thumbnail fails to load and displays a black screen instead of the intended image. This issue is observed specifically in Firefox, while the same functionality works seamlessly across other browsers.

Steps to Reproduce: Open our webpage in Mozilla Firefox. Ensure it is the first visit (clear cache if necessary). Observe the thumbnail image section.

Expected Behavior: The thumbnail should load and display the intended image correctly.

Actual Behavior: The thumbnail displays a black screen instead.

Troubleshooting Steps Taken: Verified server response and headers; no anomalies found. Checked CORS policies and ensured they are configured correctly. Tested in other browsers (Chrome, Edge, etc.), where the issue does not occur.

Request for Assistance: Could you please help us identify if this issue is related to:

Any specific Firefox rendering engine behavior? Known bugs or limitations in handling thumbnails or images on the first load? Additional configurations we might need to implement for Firefox compatibility?

Hello

I use Firefox 132.0.1 under Fedora 14 Linux. Whenever I click an urls in another application (e.g. Libreoffice, Keepass...) a new tab is opened in Firefox (according to Firefox's settings), but Firefox itself does not pop up in the foreground, it remains in the background. I highly appreciate the setting 'open links in tabs instead of new windows'. But FF only comes to foreground in case I deactivate 'open links in tabs instead of new windows'. How can I prevent FF to stay in the background in case 'open links in tabs instead of new windows' is enabled?

Thank you in advance

All of my desktop bookmarks are on mobile, but after resetting my password they won't sync back to my desktop. I can't even access them from my desktop, despite browsing data still being clearly accessible. I have 10 years of bookmarks on my mobile device that for whatever reason now will not transfer to my desktop firefox no matter what I try. Since there's no way to manually export to xml on mobile I have no way of accessing these and I am at risk of losing 10 years of bookmarks, many of which are vital to the work I do.

I have an mp4 (h264 AAC) video of 37MB which plays acceptably from my website in Safari, Chrome and Edge, but when played in Firefox (my default browser) the sound and picture synch is significantly seperated. When the video is compressed to 26MB it suffers some expected loss of sound quality but plays with near perfect lip synch. What is the issue with playback ?

im not very good with tech so ive probably clicked the wrong things, but i cant use my firefox at all anymore. only to search up 'google.com' lol. it opens on the homescreen, but when i want to search anything it always comes out on the screen in the image included. ive been using firefox for a year or so and never had issues. ive tried deleting and reinstalling, restarting my laptop, the whole deal. im on windows 10 but that shouldnt be the issue i imagine. ive asked some friends and they dont understand it either. id love to get some help otherwise i might have to go back to google chrome D:

My page throws errors in Firefox Nightly such as

Expected color but found ‘undefined’. Error in parsing value for ‘background-color’. Declaration dropped. preview.htm:1:1

and

Expected color but found ‘undefined’. Error in parsing value for ‘color’. Declaration dropped. preview.htm:1:1

The page references ten CSS files besides having dozens of its own CSS declarations. The issue is tha the reference provided to the error (:1:1) does not indicate where I can find the error. That is, I don't know which declaration is at fault. Is there some straighforward way to find the declaration in question?

The autostart of the page is attached. It is not possible to disable it. I have tried everything. I have uninstalled firefox and reinstalled it, but unfortunately the page still appears every time I start firefox. Before the update everything was fine, but after the last update it keeps showing me this instead of a blank page with favorites
