Firefox Community Forum

I am the developer of FastF1, an open source Python package for downloading and analyzing Formula 1 race results, timing data and telemetry. The package is widely used in the fan community for independent analysis of results. For some advanced features, the addon requires users to authenticate with their Formula1/F1TV account. Since their services don't have an open login API, a companion addon is required to allow users to sign in using their browser and the official website.

I have just noticed that my developer account has been banned and the addon was blocked in Firefox. I have not received any email about this and don't know why exactly this decision was made. I'd like appeal this and reinstate my account and the addon, but I don't know how to proceed from here.

FastF1 and the companion addon are fully open source and intend no harm to users. https://github.com/theOehrly/Fast-F1 https://github.com/theOehrly/fastf1-companion

I hope this problem can be resolved.

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?

On some sites where the text input isn't a proper input box, pressing Back Escape takes me back to the previous page is there anyway to fix this? (for example the wordle page.)

Recently I started having this issue. Whenever I send a tab from my phone into my computer, instead of a new tab opening in whatever window I was last using, a new private window opens and then loads the tab. At first I was only transferring one or two tabs so I didn't really care at the time, copy and paste the tabs into the old window. But when I need to transfer 10+ tabs? how aobut 40? Now it's an issue since you can't just move them. The tabs in my phone are normal too, not private. I have, of course, found no normal setting in either the desktop or android version of Firefox to control this behavior.

Recently Mint upgraded my FF to v147 - possibly relevant, possibly not. There's no post mentioning anyone having this issue on the Mint forum though.

In my Settings, "Open previous windows and tabs" is definitely enabled, but it doesn't happen. I only get my homepage custom URLs.

I went into troubleshooting mode and FF then behaves.

So I figured the issue must be with an extension - but I disabled all my extensions, and it doesn't help. Only going full troubleshooting mode fixes it.

What do I do next please?

Hi,

At some point in the last couple of weeks, I've started running into very frequent crashes running Firefox in the Linux container on my Chromebook. It previously worked well, but is now unusable. I'm now running Firefox version 147.0.3 on Chrome version 144.0.7559.167. This is after I did a clean reinstall of Firefox using flatpak, which didn't help. It seems like it often happens when my mouse hovers over a browser tab or icon (eg account, extensions, hamburger). Other quirky display behaviour, which mayor may not related, is that videos are often not working (eg Youtube, BBC), and various browser windows (eg when selecting Manage Bookmarks, or restarting in safe mode), open a small size-reduced window. Latest crash reports below -

Thanks for any suggestions.

I am trying to find a way to restore the previous tabs that I had open. All the standard restore procedures out of the History button or elsewhere are not working due to the account change. Here's the background and scenario: Original account created 1 month ago on old Linux PC New PC purchased and Ubuntu Linux 24.04 installed Firefox installed and configured, bookmarks imported from .html file. No sync account was ever signed in to. Open a crapload of tabs that I wanted/needed to interact with (yes, I need a better task management system) Finally decide to log into sync account, successful sign-in Close browser for PC restart. Upon restart, all configurations from 1 month ago on old Linux PC are present, and no previously-opened tabs come back. Restore session/restore tabs/restore browser all are greyed out, no data to access in history anywhere. Signed out of account, closed browser window and restarted. Still displaying config from old sync account even when not logged in (different theme, toolbar settings)

I am unable to locate any files in the pathway Home/snap/firefox/common/.mozilla/firefox that clearly indicate multiple profiles; there is only one distinct profile folder present. I haven't cleared cache or anything, trying to not touch it more. Is it possible to restore or even see the URLs of those tabs from my session prior to logging in to my sync profile?

Desktop Firefox 142.0.1 (aarch64) iPhone 11, iOS 18.5, Firefox 144.1 (62735)

I just reinstalled the desktop which needs the mobile phone's bookmarks. If I wipe the phone bookmarks, I lose everything. Backup, how on the phone? Sync, how? The Firefox Bookmarks Sync isn't an exact science and a misstep could be catastrophic!

Here's what I'm looking at on the desktop and the phone, attached. 1. Desktop Firefox Bookmarks Sync window show a 3 horizontal lines (hamburger icon) for iOS Firefox settings. 2. Phone Firefox has 3 horizontal dots (meatballs icon) for iOS Firefox 3. Phone Firefox has my Firefox account logged in and a Settings option, but which one (I choose Settings 4. Phone Firefox Settings shows my ACCOUNT and a Sync Now option, but which one (I don't want the phone to Sync and pull no data from the desktop and wipe the phone Bookmarks (no backups)).

Hello,

I just installed a new version of Linux Mint (Zara) and all is right with Firefox, except the screenshot who doesn't work. The buttons "Capture the visible area" and "Capture the entire page" don't work. The additional tool in the toolbar doesn't work. What can i do, please? Thanks for your answer. Pierre

Internet searches for Firefox support/forums shows https://www.mozilla.org/en-US/about/forums/ and https://www.mozilla.org/en-US/about/governance/policies/participation/

Searching around these links is too difficult to find where to post any questions, which happens to be on this link https://support.mozilla.org/en-US/questions/

Please make UX friendlier.

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

Latest update on Ubuntu force reset the sidebar. Reminder for those that do not want, the process to remove it is:

• Go into about:config in the address bar,
• search for sidebar.revamp,
• set it to false.

From this Reddit thread.

Mozilla. Please do not reset the `sidebar.revamp` for those of us that have gone to the trouble of removing it. Thanks.

I have an idea for improvement of the mozilla browser, but I don't want to send it online here. So can you please give an email address and I will send it there instead(?).

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

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 .

Hi all. I have been using firefox with ubuntu 22.04 for about since when ubuntu 22.04 was released (2022).

On firefox, I usually use the nordpass and tab grouping extensions. For the third or fourth time in a row, firefox has simply vanished from my system from day to night.

I click the icon and nothing happens. I try typing "firefox" in the terminal and get

   Command '/usr/bin/firefox' requires the firefox snap to be installed.
   Please install it with:

   snap install firefox

Even if I accept the bizarreness of snap simply deciding from one day to another that I don't have this package (or did I never have it and never needed it in the first place?) and try "snap install firefox" I get:

   snap "firefox" is already installed, see 'snap help refresh'

After reading the result of "snap refresh help" I decided to "snap refresh" to update all of it's packages. Still, "snap install firefox" and "firefox" keep giving me the same result.

What is happening here?

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

I have recently installed the containers extension and have been having a bit of trouble with one site (the others are fine), which seems to originate from the manner in which the site is structured. As it references new pages, they are often in a different URL. For example, you start in login.site.com, which then tries to load dashboard.site.com, but it fails authentication on dashboard.site.com because it opens in a different container. Which then tries to open the login.site.com page again, which displays the login page, but showing it tying to complete the original authentication. I have tried to add each step along the way, but without success. Is there a way to overcome this?
