The same thing happens on my two Dell laptops (Inspiron and Latitude), and a Hyper-V VM (on my desktop PC). They all run Bazzite Linux 6.17.7-ba25.fc43.x86_64.

A video may play for a second or two, and then it's either a black screen, or an error message of "The content doesn't seem to be working."

On the same two laptops and VM, the Chromium Browser, and LibreWolf (a fork of Firefox?), have no issues playing the same videos.

Firefox version on all three systems is 147.0.3.

Any help/guidance welcome with thanks.

I'd like to know how to hide the previews for vertical tabs in Firefox. I've already unchecked the "Show preview image when hovering over tabs" option in the settings. Is it impossible to hide them?

What happened, All my important bookmarks are missing. I have had to log into every account I have, No saved passwords. Really upset. I need help to restore all this information that I need

Hello,

I have just setup a new desktop computer which has the latest versions of Firefox and AVG Free.

Firefox is not working properly, sometimes not completely loading pages, images or is not loading pages at all.

If I disable the AVG Web Shield Setting “Enable QUIC/HTTP3 scanning” then Firefox behaves normally.

The build of AVG Free is 26.3.10886.974 and the version of Firefox is 149.0.2.

Regards,

I face an issue with the browser crashing when in google meeting (meet.google.com). The problem persist in a new profile created with 'firefox.exe -P' and also in the troubleshooting mode. The crash is triggered when I am in the google meeting (with allowed microphone) and I manipulate with windows of the browser - across multiple monitors (switching tabs, moving tabs between windows, closing firefox windows, opening them, "dropping" the tabs onto another applications - chrome, spotify - which opens a new firefox window). Sometime the crash happened once I closed the google meeting tab. Unfortunately it happens "randomly" and I was not able to come with a specific series of steps to reproduce the crash. But it happens always when I am in the meeting and play with the windows for a while.

The crash: Firefox freezes for a few seconds (~3s) and then closes itself - all windows. %appdata%\Mozilla\Firefox\Crash Reports\pending contains a new .dmp file, but it has 0 bytes and no .extra file is created, hence it cannot be submitted via about:crashes. The crash reporter is not opened when firefox crashes. The attached troubleshooting information are from the new clear profile where the crash happens as well.

Just found that using Iolo System Mechanic to clean up my desktop is constantly causing the loss of my bookmarks and possibly my passwords. I have tried to specify which file(s) to ignore in System Mechanic to avoid this issue, but it is not allowing me to specify the files in my Appdata folders that I suspect it is clobbering. Has anyone been successful with this? I am getting tired of restoring my bookmark files every time I use the program. My wife's computer is having the same issue, and even worse in that she has also had her entire bookmark backup files wiped clean, which required her to re-enter all of her bookmarks manually. The folks at Iolo want me to pay for support before I can get any help from them.

Hi,

My Firefox had auto updated to the newer version with AI built-in and auto-enabled, which meant the browser would crash EVERY. SINGLE. TIME. I would launch it.

For perspective, I am running an old Lenovo Thinkcentre mini PC with an Intel i5 6th gen and 16gb of ram; its got Windows 11 installed, and always running out of memory with the simple things like browsing and word processing. This is NOT a PC or use-case that needs or warrants AI.

So, I uninstalled Firefox (149) and installed the latest version WITHOUT AI built-in (147).

I then synced my profile, and things ran fine. An hour passed, and then i kept getting an error, saying my profile was created with whatever and I need to create a new profile.

So, I created a new profile and synced, again, and I got the error, AGAIN...

I'm about to boycott Firefox on all the devices I control, and opt for an older version of Opera or something more obscure, so that I don't have to deal with this nonsense.

I am using Firefox 149.0 (64-bit) with Yahoo.Com as my home page. All of a sudden, when I use the search bar at the top of the Yahoo Home Page, Firefox opens up a blank tab in response. Doesn't matter what I search for, same thing happens. Then, if I close that blank/empty tab and reattempt the same exact search again, it works fine.

This has been happening only for the past few days - was fine before. Is this Firefox? Or is this Yahoo? And how can I resolve the issue?

Thanks in advance.

YouTube is playing 4K videos like they are in slow motion. If I lower the quality they work fine, but switch back to 4K and it's slow motion stutter-fest again. I have seen several topics about this but it's still happening to me despite all of the "fixes" I've tried. This is a list of everything that I've seen and tried, and not a single one or any combination of them fixes the problem for me.

In about:config I tried changed the following to False: gfx.webrender.layer-compositor media.av1.enabled media.wmf.dxva.d3d11.enabled

Tried uninstalling all extensions.

Tried a complete uninstall and reinstall of 149.0.2 with a fresh profile instead of updating from 148.0.2.

Tried installing uBlock Origin and used the following rule: ||www.youtube.com/web-reports$xhr

Tried unchecking the uBlock "Quick Fixes" filter.

Tried disabling hardware acceleration.

Tried disabling DNS Over HTTPS.

All that said... what DID fix it was reverting back to Firefox 148.0.2. I tried again to update from that to 149.0.2 using the FF built in updater but the same issue immediately came back. Zero issues at all playing 4K YouTube videos on FF 148.0.2 or the latest versions of Chrome and Edge. Issue is ONLY on FF 149 and 149.0.2.

Hi there,

I woke up this morning and opened firefox. Normally it opens the days previous tabs and this morning it didn't. When I tried 'restore recent tabs' it didn't do it. When I went into history and found the previous day's back up and tried to restore it also failed. Can you help?

Best wishes, Inez

Suddenly—with no changes made in Firefox, no power failures, no anomalous occurrences, and with the latest version of Facebook—Facebook would not display reels when clicked on.

What came up was at first a briefly (maybe a second) displayed image, but rather than remaining, the image disappeared, leaving an all-black screen except for the usual icons normally there: in the upper left, the "X" for closing the window and the Facebook logo; in the upper right, the Facebook menu, messenger, notifications, and account icons; at the middle right, the up and down circled arrows (which function but which lead to more displays of only black as well); and lower-right center, with the vertical display of the thumbs-up emoji, comment, share, the three-dots more options icons.

Firefox 149.0.2 is installed on a Windows 11 computer less than a year old (which has displayed no anomalous or unusual behavior at all).

Clearing the Firefox cache and restarting Firefox have done no good. What is wrong here?

Thank you.

All of a sudden I can't download files from apps I use all the time... and download files from all the time. I just tried in Edge & I can download just fine. This just happened this morning. I downloaded multiple files yesterday within firefox & the same apps I'm running today.
