I understand that in previous versions, there was a preference in about:config that would let me adjust the delay in ms that I would need to hover over a tab until its tab preview is shown. This preference is supposedly located at browser.tabs.cardPreview.delayMs but when I searched for it in about:config it did not show me any results. Any Google searches do not point me in the right direction either. Does anyone know what I could do to adjust this delay anyways?

Attached is an example of the tab preview I'm talking about.

duplicate of /questions/1509077 thread

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.

It seems like every week I've somehow muted the audio in a tab. I think this started a few months ago, but I can't remember seeing any sort of an "upgrade" alerting me to this new functionality. How do I get rid of it?? It's driving me nuts. I search google for a solution, and it's horrible AI search just refers me to an ancient thread that does not work.

Btw, I just saw an announcement by Mozilla about modernizing itself. How about getting rid of the crazy About:Config and making it easier for users to make changes?

Is there a way to fully disable HDR support in the latest Firefox (138.0.1)? I use it on Linux/Gnome (wayland) where even though HDR support is disabled system-wide (gdctl confirms that) as well as on the monitor, Firefox insists on displaying YouTube videos in HDR resulting in washed out colors.

Looking into the issue I found that disabling the config flag layout.css.video-dynamic-range.allows-high seems to disable HDR but I'm not sure if this is the appropriate way or if there is another switch I currently don't know.

Any help is welcome!

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.

Hello, Until recently, I was able to double tap the browser bar and have the window expand to fill the screen just short of "full screen" mode so I could still see the menu/task bar. I remember I did need to adjust settings for this somewhere but can no longer figure it out now that it is not functioning to this spec any more.

Hi!

I am seeing the message in the subject line having completely removed all trace of snapd and installed Firefox deb under Ubuntu 24.04 using the ppa https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu

about:support says "User Namespaces false — This feature is not allowed by your system. This can restrict security features of Firefox"

The page shown following the link does not help as it just assumes I have installed from a tarball - not the case.

Any idea whats going on?

I am using the plasma DE having installed kde-plasma-desktop if that's of any consequence.

Thanks for looking

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?

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

So how on earth do we stop this stupid search option in the url bar. When i open a new tab, i'll get on a firefox tab. In the middle I can search (in the search bar), but after typing 1 letter, the search is moved to be in the address bar. WHY????

I had the same problem as, for example, this:

 https://support.mozilla.org/en-US/questions/1375244

firefox (on linux) was unable to open a file browser to the local filesystem on clicking a website-provided button for file uploads, e.g. here https://video-converter.com/

I have seriously messed up with firefox settings over the years in order to safeguard my privacy, against all the attempts by firefox to infringe it. (Admitteddly, not as much as google chrome, safari and, got forbid, m$ edge). One of these fixes was to link the file/database content-prefs.sqlite (found in my firefox profile dir) to /dev/null. It was this that caused a problem with the file browser not showing. WOW!

Once I deleted said file (linking to /dev/null). Firefox started and all was OK wrt the file brower.

That caused me to create a script to be run before and after firefox launch, searching for all these privacy-infringing databases in my profile dir and erasing them.

The steps to this are: 1) edit /usr/share/applications/org.mozilla.firefox.desktop and replace all Exec=firefox entries with Exec=/usr/local/bin/firefox-custom.sh 2) create a new file /usr/local/bin/firefox-custom.sh with this content

  1. !/bin/bash

CMD="firefox" if [ -x ~/bin/firefox-custom.sh ]; then CMD=~/bin/firefox-custom.sh fi echo "$0 : executing firefox with this command :" echo " ${CMD} $*" ${CMD} $*

3) create a ~/bin/firefox-custom.sh file with this content

  1. !/bin/bash

function eras { local f="$1" echo "erasing file '$f' ..." rm -f "${f}" }

echo "$0 : on starting, erasing various sensitive firefox databases ..."

while IFS= read -r afil && -n "$afil" ; do eras "${afil}" done <<< "$(find ~/.mozilla/firefox -type f -name 'content-prefs.sqlite')"

echo "$0 : now executing firefox ..." firefox $*

echo "$0 : on exiting, erasing various sensitive firefox databases ..." while IFS= read -r afil && -n "$afil" ; do eras "${afil}" done <<< "$(find ~/.mozilla/firefox -type f -name 'content-prefs.sqlite')"

lanuching firefox now either from a desktop file (e.g. via Plank launcher) or from the command line: gio launch /usr/share/applications/org.mozilla.firefox.desktop runs the above script before and after firefox running.

Disclaimer: the above script erases files in your profile directory, use at your own risk. Perpahs make a backup copy of your profile dir before.
