Firefox ერთობის განხილვა

I have to manually change the layout.css.devPixelsPerPx setting evertime I switch from my laptop to an external monitor. What can I do to avoid this every single time?

Hi. I have followed the instructions on the Mozilla site above however this does not work. The Enterprise Roots keep reloading after a while.

Any idea how to stop this happening?

I have read many articles on this but nothing works. The E Roots will in initially not reload but eventually after a day or three its back.

Many thanks

When accessing about:logins, Firefox prompts for system authentication (Primary password or master password). However, if the user cancels the prompt twice, the password manager still opens and displays all saved logins without authentication.

This behavior bypasses the intended security check and could pose a risk, especially in shared or public machines

Hello,

I have old 15 year old mac el capitan -10.11.r with outdated firefox 78.15.0esr 64-bit.... in perfect condition. Unfortunately I can not make updates on browser anymore. Online banking websites does not allow me to use this outdated browser. Would you be so kind to make even paid update for me? Or at least let me know what settings I should change under about:config

Waiting to hear from you! [edited email from public]

Hello,

as per description I noticed that firefox version 138 requires an ArrayBuffer as the argument of WebAssembly.compile() and doesn't allow anymore (like in 137) a SharedArrayBuffer, is this intended or it will be fixed in the future? Follows a simple test case. Kind reagards.

--- index.html --- <title>Example</title> <script> let instance = undefined; async function loadWasm() { try { const response = await fetch('./sum.wasm'); const buffer = await response.arrayBuffer(); const sharedBuffer = new SharedArrayBuffer(buffer.byteLength); const tmpView = new Uint8Array(sharedBuffer); tmpView.set(new Uint8Array(buffer)); const module = await WebAssembly.compile(sharedBuffer); instance = await WebAssembly.instantiate(module); } catch (error) { alert(`failed to compile in wasm: ${error.message}`); } } loadWasm(); function testWasm() { if (instance) alert(`sum 1 + 2 = ${instance.exports.add(1, 2)}`); else alert('invalid instance, failed to compile'); } </script> <button onclick="testWasm()">Press to run wasm function (sum)</button> --- ---

--- sum.wat --- (to convert into .wasm using: wat2wasm sum.wat -o sum.wasm) (module (func $add (param $lhs i32) (param $rhs i32) (result i32) local.get $lhs local.get $rhs i32.add) (export "add" (func $add)) ) --- ---

I have tried every support advice I can find and no matter what I do passwords are not restoring. Here is what I have done: Opened about:profiles Opened profile folder Exit firefox transfer key4.db and signons.jstor files from backup to the new folder

Nothing happens.

I have tried creating new folders and following those steps. I have tried everything.

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.

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.

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.

new Date(1743623960000).toLocaleString(['en-ES'])

outputs "4/2/2025, 7:59:20 PM" in normal firefox and "2/4/2025, 7:59:20 PM" in Firefox Developer. Test on MacOS and Ubuntu.

Is there a way to make the URL high lighting of the domain more obvious? I find that most people can barely see the highlighting and I'd like to make it obvious (bolder and red, or highlighted in yellow, for instance.)

Can this be done via userchrome.css?

Thanks,

Thane

I need to block domain in my Firefox. Lets say example.com. Better if via about:config

Extentions is not a solution (sorry, I cannot comment this for privacy reasons)

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.

Recently (around Fx 134) css code for chrome files stopped working. The code I use is set out below. It previously changed the background colour to tan ( #dbc3a3 ), the text colour to dark blue ( #000080 ) and the font size to 17 px. The code found at the following location also no longer works for chrome files : https://gist.github.com/MrOtherGuy/c592f6443dd228022966cbe5715ad5c9

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.
