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.

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.

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?

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.

Hi, the home page shortcuts used to be bookmarked sites I selected, and they stayed in one place. After a recent update Firefox litters the page with recent searches, displacing the ones I saved. I can't see a setting to select recent search shortcuts ON/OFF, how to restore the old (and very useful) shortcuts?

Hi, I recently started using Firefox's beta built-in VPN and look forward to the protection it will provide. One small problem... every time I close Firefox, the VPN deactivates, requiring me to manually activate the VPN. How do I set VPN to remain active all the time? Thanks for your support. Stay well.

I normally have 4 windows open, each with multiple tabs, for 4 work streams.

Whenever Firefox or MS decides to do an update, one window sometimes, 4 rarely, none usually, are recovered after restart. How can I ensure that Firefox remembers all the windows and their tabs before shutting down? Then reinstates them after starting up. After the last MS update, the option "Recently closed windows" was greyed out. But there had been 4 of them.

Firefox's recovery after simply rebooting the computer is more, but not completely, reliable. Win11 on a desktop computer

Thank you

I just lost my bookmarks again, it happened a month or so ago as well. Appears to have been due to updates.

I have already followed the recommended ideas of navigating to restore, but there is no date given to restore to.

Just "choose a file comes" up, and that appears to lead nowhere.

I also went about:profiles , and all that was there was the current "cannot be deleted " profile and the option to make a new one, I tried that, it did not restore bookmarks. I need some of tose bookmarks quite badly this time

What more can I do ?

Starting the Windows 11 laptop again. Then Firefox. Result: No sites are starting. All history lost, many tabs: lost. Great work!!! Last update was already shit (many exception rules have to be set manual again. I love such updates! Useless). And now that. I think I will switch now to chrome. Sorry. Such experience is enough. It is my time - I need a reliable browser, not where I have to spend time to get the things like they have been before

A windows update occurred this AM 04/15/26 and it has affected my browsing. Don't know if this update effected my G mail. My U tube profile changed form browsing to history. example: when I click on to my U tube profile it brings up the last view I was browsing. I cannot refresh Firefox like before from the help menu, of which would select the profile I desire.

I tried a restore but the only date available for bookmarks was today (jsonlz4 file). I tried other online suggestions but I cannot locate any old files to restore from. If I cannot get them back, I will switch browsers because the loss is unacceptable.

Whit the new things of the profiles or something I just didn't like it so I just delete the thigs that appear in my face, but that deleted all my stuff(hystory, bookmarks, passwords), I supossley had all on my account on mozilla but it's not there, i don't know what to do, I already try the backup or something that appear in the support page but the only profile that is older than the rest doesn't work or is empty, pls I need help
