I love vertical the tab view. Unfortunately, on one of my systems, vertical tabs to not render correctly. Groups are shown, but there are no favicons or titles shown (see attached image). The tabs are also not clickable. Any insight into how I could debug that would be amazing!

Good morning, today I downloaded Debian 13 Mate version and to install Firefox I entered the following commands taken from https://support.mozilla.org/it/kb/installare-firefox-linux#w_installare-firefox-tramite-il-pacchetto-deb-per-le-distribuzioni-basate-su-debian-consigliato and the commands were

sudo install -d -m 0755 /etc/apt/keyrings

wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

echo ' Package: * Pin: origin packages.mozilla.org Pin-Priority: 1000 ' | sudo tee /etc/apt/preferences.d/mozilla

sudo apt-get update && sudo apt-get install firefox firefox-l10n-it

but I get this result OpenPGP signature verification failed: https://packages.mozilla.org/apt mozilla InRelease: Sub-process /usr/bin/sqv returned an error code (1), error message is: Signature by 35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3 was created after the --not-after date.Il repository "https://packages.mozilla.org/apt mozilla InRelease" non è firmato.

What mistake could I have made? Apart from the fact that now we use sudo apt update && sudo apt install Thank you in advance for your response.

I have HDR working in Proton games and mpv fine (using Plasma 6.4 / Wayland)

I enabled HDR in Firefox (gfx.wayland.hdr), and HDR content works in YouTube fine ( looks amazing!) however.. I have an issue in that all non HDR content doesn’t show any video (I have sound) just a green sceen (see screen shot) including all ads.

Any idea how to work round this ?

I have AMD 7800 GPU .

Cheers

I have [[created a backup file|https://support.mozilla.org/en-US/kb/firefox-backup#w_protect-your-sensitive-data-with-a-password]] today with the latest available Firefox and switched to a new OS. Sadly, the backup file somehow seems to have gotten damaged, even if Firefox still recognizes when I'm inputting the wrong password. On Ubuntu, where I originally created the backup and where I tested it again after things weren't working out, Firefox tells me that there is an issue with the file and that I should try a different one (which I don't have). On CachyOS, which I'm currently testing out, restoring the backup never finishes and Firefox doesn't exit cleanly. In hindsight I obviously should 1) have tested the backup immediately, 2) not have wiped my laptop prematurely, and 3) have backed up the folders manually, but I haven't. Now the question: is there some way to extract the account details from the .html file? I don't care much about the rest, but restoring the accounts in some other fashion is gonna be a lot of work.

Hi there! The New Tab page looks great with white text, but Firefox 140.0.4 thinks my wallpaper is white, so text should be dark. I can change the body class to "activity-stream darkWallpaper" using the inspector and it works fine, but how make this change permanently?

New installation of Debian 13, Firefox setup with sync on successful. However, I wanted to add hone button and a few other mods to the toolbar but when I started customize the toolbar from menu pic the customization page would not work, it appeared and seemed OK but when I dragged and dropped anything it would not work. I could pickup items but they would not place in toolbar and just snapped back to the pallet. I tried several different ways to enter the customization area but it was always non-functional.

Hello, I just used the Firefox 141.0 (aarch64) wizard for Raspberry Pi OS 1.0, to import bookmarks from Brave, however the wizard said 0 bookmarks imported.

I also manually exported and imported the bookmarks.html file and the latest bookmarks aren't appearing at the top. It seems the bookmarks are nested in some bookmarks directory by default. I'm confused?

Also I tried a manual import several months ago but same issue about some strange nesting structure rather than simply appearing at the top. Now I'm really confused and worried I'll lose my bookmarks as there's about 3 version in various nested structures. Please help just make an easy move to Firefox.

I have a home server 192.168.0.240 in my local network. Firefox does not let me in to my own pages. On the address line appears text "Not secure",

I have found no way to get in. I have there REALLY IMPORTANT TOOLS AND MATERIAL and I need it AS SOON AS POSSIBLE !!!!

This is really stupid. I have used these pages until this weekend. I have had this problem many years, but always found some way to make it work. I am NOT going to buy a certificate to every server I have home. it costs $$$$.

I want to migrate everything from windows to linux, i've already synchronised browsers on both systems, but settings on linux didn't get overrided.

How can i make browser on linux exactly the same as on windows (including settingd)?

When I try to run firefox 141.0 (Linux x64) I get:

libxul.so: undefined symbol: gdk_wayland_device_get_wl_seat Couldn't load XPCOM.

Is there a way to fix this?

I'm using Slackware 14.2.

Hello!

'I have the menu bar enabled-

When I go to "History", the settings

I want my tabs back!

I have searches from a year (or more) ago that are still popping up and I don't know why. I have done multiple clears of my entire history and individually removed old searches when they pop up - they still keep coming back.

Mint 147.0.4 64 bit I click on a pdf, it opens in qpdfview. It also saves in wherever my default save folder is. I later have to go remove all these junk PDFs from Downloads or wherever because I either didn't want them or saved them elsewhere.

Please stop "helping me". I do not want to be "helped". How can I stop this auto-save """feature"""?

I think this started back in 98.

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

I am running Firefox 144.0 on kubuntu 24.04.3 LTS I have lost sound on Firefox. I have opened the same sites in Chrome and the sound is working fine. It's only in Firefox. I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?
