This button that looks like a jig saw bit will not budge.

Can I delete this in about:config by deleting the 'unified extention button' and can I delete the 'HKLM/SOFTWARE/Wow6432Node/Mozilla/Firefox/Extensions' in the registry?

Firefox these days is getting a burden with more info and such like being collected behind out backs, it's about to be ditched on all my computers, the last few episodes make me want out.

Dave.

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.

Transferring bookmarks & backups for passwords is easy and I'm not worried about that. But the about:config settings that I have customized and accreted over years so that nothing beeps, spins, auto-plays, loops, or throbs a tab, are not so straightforward. I'd like to review what files I can save how to make sure I do not lose these, which are the most important things to me about my Firefox installs--keeping the web safe for quiet, nondistracting searches and reading.

Windows 10 Enterprise, managed by my organization, but with just enough admin privileges to customize my Firefox.

Good day everyone,

I have been breaking my head over this for about a week. After the last update that was installed, now my tab width is smaller than the minimum width I have set them to. However, this only happens with active tabs from pages that have an embedded video. At first I thought this was just a thing with YouTube, but it seems it also happens with other video sites. I guess it may be related to whenever the playback button displays in the tab title and it detects there is video content.

I would like to know how to fix this behavior so that my tabs are no longer shortened beyond the minimum width setting.

Thank you in advance.

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.

a website im using is trin to call an api with referer header and policy of "origin-when-cross-origin", but firefox overides it to "Same Origin Policy" with console msg: Referrer Policy: Less restricted policies, including ‘no-referrer-when-downgrade’, ‘origin-when-cross-origin’ and ‘unsafe-url’, will be ignored soon for the cross-site request

After a lot of search, i found that network.http.referer.disallowCrossSiteRelaxingDefault config setting should be set to false to allow any policy, but toggling between false or true has no affect. The request still fails with a cors error "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at..."

Is there a way to make this work? Or a way to allow the request to have this referer policy.

Recently in our workplace, we had several computers that suddenly stopped being able to access several websites, the issue started shortly after pushing a updated Firefox across the floor.

I tracked the issue down to being related to security.tls.version.fallback-limit defaulting to 4, instead of the old 3.

Setting the value to 3 resolves the website accessibility issue.

A.) How can I confirm if this is a recent change or not? Everything I read seems to indicate the default should already be 3, but its very definitively not.

B.) What is the best way to push a pref adjustment change across the floor if the option isn't present in the registry and isn't a GPO option? Is my only option really to make some script that scans every computer's users folder, check every user folder's appdata\mozilla, scan every profile for a pref.js file, and do a string search for a reference line and then do a line addition if a certain string doesn't exist?

I can do this, it just doesn't seem like a good long term fix as I would have to run this script regularly as users come and go....

I am on FF 128.7.0esr (64-bit) under a new profile.
