Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

Recently, when I click on the email envelope shortcut on my FF desktop, it keeps launching the MS "New Outlook" installer instead of opening my desktop Outlook like it always did. Like so many others, I refuse to use MS Cloud for my email so they can sell my information. Thanks

Please for the love of God, get rid of the asinine Show All when opening about:config. It was a stupid unnecessary change (IF IT AIN'T BROKE DON'T FIX IT) and your users have been bitching about it since it was implemented.

Hello We have used about:config / app.update.url to change an internal webserver http://<internalserver/firefox This webserver is an IIS server with the latest Firefox EXE (<strong>Firefox_Setup_138.0.exe) on it. It has directory browsing enable and we have confirmed we can see and download the file OK. However, when we perform Help / About, you see Firefox Checking for updates... but then says Failed to check for updates. What are we doing wrong? Where can I check for errors? Thanks

I had to restart firefox but when i did it reset all my settings. I tried to increase the zoom through about:config but it does not work anymore. I've tried both ways below-nothing works/changes. Please help, it is extremely difficult to read my toolbar. This should just be a simple setting, ugggh.

Way 1. To zoom the whole browser. This will change more than the tabs.

   Open about:config

   Search for layout.css.devPixelsPerPx

   Change the value Slightly, such as 1 to 1.1 or more. The larger the value is, the bigger the contents are. Be careful, this may zoom in or out too much to see the viewport.

Way 2. To change the font size only of specific parts. This would be harder but safer.

   Open about:config

   Search for toolkit.legacyUserProfileCustomizations.stylesheets and toggle it to true.

   Go to about:profiles

   Find your profile's Root Directory and click Open Directory.

   In your profile directory, create a folder called chrome

   Open the chrome directory, and create a text file named userChrome.css

   Put the text below into the userChrome.css file

Hi, hey I forgot my PIN that allows my to view my passwords. The bubble that pops up says "You can reset your PIN by going to Settings > Accounts > Sign-in options". I'm not seeing it. Firefox Settings search is of no help. Any Ideas? Thank you.

I've been using Firefox since 2020 (Kubuntu 20.04 LTS) with a bit of a custom setup:

Since I like moving Data between my Windows and my Linux a lot, I've got a NTFS partition that mounts into my user in Linux.

So /home/user/Desktop or /home/user/Downloads, or [...] is a bind mount that mounts the NTFS user directory there. And since it's Linux and NTFS, this means all files have 777 root root permissions.

This worked fine back in the day. Moving to 22.04 LTS and then 24.04 LTS, I had the problem that Firefox came as a snap. And for snap to allow it to write to the Download directory, I needed to install it in development-mode. And because of my weird setup, I also ran into issues when uploading files.

So I moved to the version of Firefox provided by the mozilla ppa. And this worked.

However the nasty surprise came with version 138.0. First off, it was installed with snap. It ignored my pinned ppa and it did so without warning. I found it weird that once I launched Firefox, all my tabs and bookmarks had disappeared. And once I got the glitchy Downloads again where it would create 10'000 files per download with size 0 I put two and two together and checked the install source. And wouldn't you know it - snap.

Just as a general PSA: If I go through the effort of adding the ppa, pinning it as the prioritized one I wish for that package to fucking respect that. What else would you expect? A Laptop just happens to have the mozilla ppa pinned. And that just so happens to also be a Laptop that has Firefox installed from said ppa. Of course that's a mistake. Because it's less secure so it needs to be fixed for the user of said laptop. Mozilla you can stop pretending to know better how I want my laptop setup.

However with that not enough - the new Sandbox for Firefox (or whatever new feature this is I'm fighting) now also prevents it from downloading to my Downloads folder with the same 10'000 file issue. And even worse, I cannot edit the target directories for Downloads. It doesn't open the directory selection dialog.

So my question: How do I bypass the write protection for mounts with Firefox 138.0? And if that doesn't work how do I "unsandbox" Firefox?

PS: Mozilla and your Dev Team, get back to your roots. You're an open source project stop doing this corporate bullshit. First the TOS now this shit. You're starting to rival Microsoft treating user settings as suggestions.

So I downloaded a font, It was a helvetica one, and now it shows up on specific websites. I deleted it, restarted my computer, (which also got stuck on the restarting screen) and it still shows up. I probably wouldn't mind, but the font doesn't really look so good, so I need help!

In the image, the font is supposed to be roboto, but it definitely isn't that!

I've been using Firefox in Windows for years as my default browser. Suddenly tonight, Microsoft Edge became my default. When I go into Windows Settings and try to change back to Firefox, Windows offers me only Microsoft browsers as alternatives (or offers to let me into the Microsoft Store): Windows Edge or Internet Explorer.

The Control Panel / Settings page "Set Default Apps" is the only way that I know that Windows lets users set default browsers, but it suddenly seems to be restricting me to only MS browsers.

Firefox works normally in every other way, but warns me now every time I launch it that I have a different default browser. When I click the button in the warning (or in Firefox's Tools / Settings) I just get put back to the Windows "Set Default Apps" page, which, again, only lets me choose Microsoft browsers.

What could have happened? I haven't altered my Firefox configuration or installed extensions or plug-ins in a long time. If I uninstall & reinnstall Firefox, will I lose my many configuration & interface settings and will I have to reinstall all my extensions -- or will the reinstalled Firefox remember its existing configuration? Or would that probably not help at all.

I'm very computer-savvy, but have run out of ideas. Can you help??

When I open gmail on Firefox it is automatically opening a new email tab. How do I disable this?

I also cannot select gmail in my "mail to" applications.

OS: Linux Mint 22.1 Xia base: Ubuntu 24.04 noble Firefox: mint-001 -. 1.0 / 137.0.2 (64-bit)

When starting Firefox with a completely new generated profile, I still get following errors in the Browser console tool:

For example (see attachment): services.settings: UnknownError: IndexedDB: main/moz-essential-domain-fallbacks getLastModified() IndexedDB: The operation failed for reasons unrelated to the database itself and not covered by any other error code. Module: RemoteSettingsClient.sys.mjs:555

At this time using Firefox, I haven't configured a Firefox sync-account, to sync settings with the central stored profile on Firefox servers.

Solution: May it is helpful, that if a sync-account isn't configured by a user, these function calls should be suppressed by Firefox, in order to avoid these exception/error messages in Browser console. These error message are just irritating messages, as long as a sync-account isn't configured and activly used.

My settings does not have an option to enable Firefox Labs so I can enable AI support.

• Firefox browser.preferences.experimental.hidden was set to true and I changed it to false with no change in results
• there is no "Firefox Labs" section in my settings anywhere and I've checked "General" and "Privacy and Security"
• toolkit.experiment is set to true
• browser.ui.experimental set to true
• labs set to true

Found redit discussion with the same issue, but no solution

According to this page the option should be in my settings, listed after "sync" and before "more from Mozilla."

I've attached an image of what my settings menu looks like. There is no option for the labs.

What else should I try/do?

Note: using Firefox on Desktop PC. Not a mobile device. My Firefox version is 130.2.2

KINDLY KEEP BROWSER ACTIVE AFTER SWITHCHING OFF THE PC AND WHENEVER I OPEN THE PC MICROSOFT WINDOWS SHOWING SIGN OUT AND SIGNING AGAIN, BY DOING I DID IT BUT NO SOLUTION. IT HAS BEEN HAPPENING FROM FEW DAYS, I DID SYSTEM RESTORE BUT NO SOLUTION WAS FOUND.

Please provide the exact requirements for defaults in order to have the settings (occurring on the bookmarks settings) to state that Firefox is your default browser. Having had to attempt this process multiple times causes me to question if it is the user that needs some "tender loving care".

I have tried to make Firefox my default browser on my Dell laptop dozens of times and it keeps switching back to other browsers. How can I set if so it does not keep changing my default browser from of being Firefox? I have set is as Firefox default and it keeps changing it from Firefox. Many thanks, Alan

I have bookmarks for the application Obsidian, which uses the obsidian:// protocol, registered in Windows. I type the bookmark keyword, it opens the protocol, and asks to confirm whether I not want to open it.

While I wish I could get rid of the entire dialog, I understand that's a security risk, and I understand that the manual delay is ALSO a security detail (to prevent errant or intentional mis-clicks by malicious websites), I want to disable it.

I'm aware there's a lot of hidden configuration options, but I can't even find the name of what this dialog is called. Every search I have for it yields unrelated results. "Open with" is the only idea I have now, so maybe I should start searching for what the integration or protocol is called within Windows. Maybe that'll put me on the right track.

So, can I disable OR 'configure the confirmation dialog, either altogether OR the delay?
