I have set four custom URLs to open each time I use my main Firefox profile - this works well. (I have several different profiles I use for different roles and sets of logins).

I frequently open new windows to hold a set of associated tasks.

If I specifically open a link into a new window, the new window only has that one tab - all good.

However, if I just open a new window (Ctrl-N), Firefox always opens four new duplicate tabs for my custom URLs.

Is there a way to limit custom URLs to the first window opened in a profile or to open custom URLs only if they are not already open in at least one window?

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

I'm at a loss here, problem is in subject line. This has happened for a long while and has persisted through various versions, I have attempted to:

- Alter my antivirus and internet protection settings to allow as much traffic as I can. - Download addons as XPInstall files and try and use the File -> Open File option in the Menu Bar - only returns a line about not having permission, despite having Admin permission.

My Firefox Version is the current 118.0.2 (see: attached image).

Thanks in advance.

Is there a way to create a new keyboard shortcut to copy current tab URL?

I've been using Arc to try some of their features, and what I miss the most is the hability to copy current URL to share without touching the mouse.

I really often need to copy/paste from a terminal opened in my browser. Because the shortcut for copying in a terminal is always Ctrl+Shift+C, it's a mess to have instead Firefox opening Inspector from devtools.

How can I disable this shortcut ?

I've tried to update some about:config settings but it doesn't seem to be helpful and old working correctives add-ons are not supported anymore.

Hallo there, somebody knows how I could on my side the log out timeout of any website where I have a login some longer? I am using a forum (ubuntuforums.org) quite often and after only few minutes I am logged out, I have to login again. This is annoying. I would love to manipulate such logins so that the site thinks, I just logged in and does NOT log me out automatically after x minutes or seconds.

Is there such Add-On or setting? I guess its the expiration date of session cookies, isnt it that, where these log outs are calculated? Thanks for hints, I am on Firefox latest (119.0) on Windows and Ubuntu. frank

I'm using Firefox 112 on Windows 10. The toolbar contains icons for several extensions that I don't want to see. I click on the >> menu and then Customize Toolbar. That opens the Overflow Menu. It says, "Drag and drop items here to keep them within reach but out of your toolbar." I try to drag one of those extension icons onto the Overflow Menu. It won't go. The dragged icon picks up a circle with a line through it, indicating that this is not allowed or not working.

How can I use the Overflow Menu as advertised, to remove unwanted extension icons from the toolbar? Or is there a good workaround?

When I go into fullscreen on firefox macos, hovering near the top shows the traffic lights (fullscreen, minimize, close window buttons) and moves everything down. This may be expected behavior, but it is very annoying as when you try to open new tabs the tab bar moves out of the way of the traffic lights, and the traffic lights area is around the size of the tab bar. Is there any way to make the traffic lights always visible or keep them from moving?

Hi

I have a new mac mini with ventura. I am trying to transition from Chrome to Firefox and I have one single thing that is stopping me from doing that.

It is the color of the scrollbar thumb. Currently it is light grey on slightly lighter grey. Almost impossible for me to see with my older eyes.

What I've done so far is to set this to true in the firefox config:

toolkit.legacyUserProfileCustomizations.stylesheets

and created the userChrome.css in the correct profile folder (from firefox troubleshooting information page)

What I want is that anytime the scrollbar displays, I want the thumb to be blue so I can see it. I've not been able to find the css to do this.

Please help me with this, Chrome has become almost unusable and I need to switch to Firefox.

thanks Nick

Hi, I made a theme but have since not used it and swapped to another. Everytime I open the browser, it swaps back to the one I made for some reason. Under themes, it will still say the one that is showing is the chosen theme, but it most certainly is the one I made. I turn on another theme and toggle back to the chosen theme and it then changes correctly. Any idea why that could be?

I have AdBLockPlus (free version) installed and have not had any issues until today. Firefox did some updates and now the Add-In is no longer working. I have checked that it is specifically turned on for the websites I'm visiting and I've tried turning it off and back on to no avail.

I am having a hard time getting accustomed to the Firefox scrolling experience. I am only using the touch pad and the touch screen. When I release the finger the time it takes for the scroll speed to come to a halt is way longer than on Chromium browsers and uncomfortable. I want to configure this to decelerate faster or to remove the smoothing completely.

I have tried playing around with scroll configurations and I found that setting apz.gtk.kinetic_scroll.enabled =false disables smoothing correctly, but only works for touch pad, not for touch screen.

- Is there some config I am missing to disable this kinetic scroll using touch screen? - Is there a preference where I can halve the time it takes to decelerate, rather than disable it completely?

I am running Ubuntu 22.04 on Wayland if that makes a difference.

I've searched for answers. I tried the About:config and changing some settings to false and others to true as suggested (e.g. browser.search.context.loadInBackground), etc., and of course I have the option chosen under settings.

This is a new computer. My old computer would switch to the new tab when I right click it, but this new one won't.

Any latest fixes?

Is there any way I can completely disable horizontal scrolling? I'm using a laptop with a trackpoint (lenovo x230, Windows 10) and it's not terribly accurate, which means scrolling whilst a youtube video is going often makes it track backwards or forwards, and another website I use uses a horizontal click to send me to the next page, which sucks. I would prefer to just be able to disable it entirely. Thanks!

I swear to god I used to have it disabled, just need to work out how again.

OS - Ubuntu22 Firefox - Default firefox on ubuntu22 (Mozilla Firefox 103.0.1)

Use case - 1. Custom profile folder (named prof1) contains pref.js and chrome folder with custom css file. 2. prof1 is created in -> "/customData/profiles/prof1" 3. The folder "/customData" has full rwx permissions and is owned by $USER (not by root)

Output -> 1. When launching firefox mentioning the profile -> "$ firefox --profile /customData/profiles/prof1"

The browser does not load, but there is an error box saying Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible.

Questions -> 1. Is it possible to load firefox profile from root directory ? 2. If custom profile folder is created in "/home", then it is launching and working perfectly. How is this possible when the permissions and owner is same as the one in "/customData"

I've tried following both methods for dissabling the mute button on tabs, it's a slight annoyance, since it's easy to accidentally mute a tab when it's pinned.

Specifically, the first method I've tried changing the setting in about:config called "browser.tabs.showAudioPlayingIcon" from true to false, which was from 7 years ago it seems, which had no effect.

The second method was by making a new rule in a "userChrome.css" file in a new folder called "chrome" with that exact naming, case sensitive. The code in that file is as follows:

/* Hide the mute/unmute button */
.tab-icon-overlay:not([pinned], [sharing], [crashed]):is([soundplaying], [muted]) {
    display: none !important;
}
/* Keep site icon visible on hover */
.tabbrowser-tab:hover .tab-icon-stack:not([pinned], [sharing], [crashed]):is([soundplaying], [muted]) > :not(.tab-icon-overlay), 
     /* for site icon with Compact density */
:root[uidensity="compact"] .tab-icon-stack:not([pinned], [sharing], [crashed]):is([soundplaying], [muted]) > :not(.tab-icon-overlay) {
    opacity: 1 !important; /* overrides full transparency with full opacity */
}

If there's an updated version of the code that's meant to have that effect in modern firefox, then please let me know, or if there's some other new way of removing the mute button on tabs. Thanks.

Just updated to the latest firefox version 119, and noticed that the url links are now all underlined again. Checked the support page that says it can be undone in settings, but when I opened up to the said setting page, there's no option to uncheck underline links. Where else can underline links be disabled?

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

Hello, in past versions of Firefox, I was able to follow the steps on this page to set a custom HTML file on my PC as my home page for new tabs: https://peterries.net/blog/firefox-ubuntu-local-file/

I have Firefox 107.0.1 now and it's not happening. When I open the browser from scratch, I see my custom home page file. But when I open a new tab, I just see a blank screen. If I then click the Home icon on the toolbar, I do see my custom HTML page, but I don't want to have to click that button for each new tab.

Right now, in my settings, I have the URL to the page set as the custom URL for the HTML fiile, like this:

file:///home/peter/Documents/homepage/peter-home-homepage.html

That works. And I also have followed the steps on that blog post to customize my /usr/lib/firefox/autoconfig.cfg and my ../firefox/defalults/pref/autoconfig.js files. That's no longer working.

Did something in a recent version change? Is this no longer supported? Thanks for any ideas!
