There is something wrong with Firefox Mozilla and causes me a lot of problems with websites. I am signed into youtube though says not signed in and problems with access to AliExpress account and messages. What is going on that I have to use another browser?

Hello,

I just set up a computer with Debian 13 'Trixie', and I downloaded and installed the latest Firefox for Linux (version 145) from Mozilla's site.

Then I noticed at first that it wasn't following my GTK theme. Then after testing a bit, I discovered it would respect only themes with names that end in "-dark". I've taken some screenshots and attached them to demonstrate the problem.

firefox-esr from Debian's repositories didn't have this problem. But also, I've got another computer that still has an older distro (Debian 11) installed, and I'm running the latest firefox 145 on that too, and it always respects my GTK theme regardless of whether its name ends in "-dark". So, perhaps this is a GTK/GTK4 problem or something?

Does anyone know about this issue, can anyone help? I would really like Firefox to respect my choice of theme regardless of whether the theme's name ends with "-dark" or not.

In the standart view of a video, the feature works, but not in fullscreen. In Chrome it also works in fullscreen. Firefox should have support for it since v126 or so, im on v145

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

Dear colleagues, please tell me what could be the reason why the Google AI Studio is not displaying correctly. The buttons are invisible, the fonts are stretched, and it's generally impossible to work (see the attached screenshot). Please refrain from giving advice like "update Windows to a newer version," as this is an old computer (its motherboard was manufactured in 2007), but it still opens most websites fine. I don't currently have access to a newer computer with Windows 10.

Hi,

On some websites (e.g. archlinux.org) most numbers are not rendered. See attached screenshots showing the same page on Firefox and on Konqueror.

In my font settings, I do allow pages to change fonts. Some pages (e.g. this one) do change the fonts and appear well. However, if I disable the feature, then they also break.

I'm using: firefox 145.0.2 (64-bit) archlinux plasma-desktop 6.5.3 wayland 1.24.0

Any idea?

Hi, I've got a "confirm your account" email, which I click through to get to my account but from there I don't know what to do to verify it. Is there a "verify" button that I'm missing, or an action I need to do on my account in order to finalise it? Thanks

Hello

I'm facing a frustrating problem. I asked an AI the following:

Firefox Developer Edition (v145.0.2) on Windows 11 host machine can play udemy.com videos but Firefox Developer Edition (v146.0b9) on Windows hyper-v virtual machine cannot.

I suspect the cause is due to either settings or the virtualisation Hyper-V. Other browsers (Edge, Brave) on the virtual machine can play udemy.com videos with no problems.

Gemini said: This is likely caused by a specific change introduced in Firefox Nightly/Beta (v146) regarding how it handles video decoding on Windows.

The Short Answer: Firefox v146 enabled FFmpeg-based hardware video decoding by default on Windows (previously it relied almost exclusively on Windows Media Foundation). This experimental feature often conflicts with the virtualized graphics drivers (Hyper-V Video) used in your VM, causing the player to fail (black screen or error) while audio might still work or the player simply refuses to load.

Is this true?
