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"

My setup: A remote server running CentOS Linux 7 and Firefox Browser 102.7.0esr (64-bit), accessed via RDP from a Windows 10 Enterprise laptop (No tablet)

Up in the top right corner of the Mozilla Firefox window, I have only the close button, the Minimize and the Maximize buttons are missing. In the same gnome (desktop) environment, all other running windows has those buttons available.

Note: if toggle enable or disable those buttons “Minimize” & “Maximize” [command: gnome-tweaks > Windows > "Titlebar Buttons" > toggle] , all running windows in gnome will be affected correctly, except the Firefox window, with no impact. Reinstall Firefox did not help.

This behavior started after our latest yum update recently.

When connected locally to the Linux server, there are no issues, the buttons are available. (i.e., no RDP involved)

firefox-102.7.0-1.el7.centos.x86_64 xrdp-0.9.21-1.el7.x86_64

Any tip from the community?

With the upgrade to Firefox 106 on Mac, Private browsing windows open with a dark theme by default. How do I enable the light theme for Private browsing windows?

I use Private browsing at work for website testing, and the dark themed tabs / UI are much harder to read and use than with a light theme.

Hola , alguien sabe como puedo ver los videos de Disney plus en pantalla completa , sin las barras negras , al parecer los vídeos son 21:9 y mi monitor es 16:9 , alguna extensión que si funcione para cambiar la relación aspecto o hacer zoom ? gracias de antemano

Hello, does anyone know how I can see the Disney plus videos in full screen, without the black bars, apparently the videos are 21:9 and my monitor is 16:9

Extensions no longer shows on Customize Toolbar tab on the latest version 111.0. I had Dark Reader and SoundFixer on the toolbar before and I can no longer add them back.

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.

Hello, Firefox always downloads a pdf files from e-mail attachments, whether I open it in a browser or with acrobat reader. So, if I open the same file every time it goes to download folder with multiple clones, like example file-1, example file-2 etc. I've used every combination of options, but the result is always the same. I've refreshed Firefox, but nothing changed.

Please help me with this case.

Hey guys,

is it possible to disable the "saved logins" dropdown, whenever a password/email field gets focus? (see image)

I've already disabled "Autofill logins and passwords", but that just disables not directly autofilling the field.

I want to disable this field, since I can still use saved logins via right click "use saved password", which i prefer.

Its no form field, i've already checked that + it occurs on all login pages.

The only options i've found where: "signon.showAutoCompleteOrigins" - hides from which website and "signon.showAutoCompleteFooter", which hides the lower part with "view saved logins"

Is there a way to disable this Dropdown completly, without loosing the auto save/ask to save new passwords?

Kind Regards

Firefox 104.0.1 (64-bit) - Fresh install (just imported logins)

Procedure is written on this article: [[Tip] Enable Firefox to Show Media Controls on Windows 10 Lock Screen – AskVG](https://www.askvg.com/tip-enable-firefox-to-show-media-controls-on-windows-10-lock-screen/#:~:text=If%20you%20are%20using%20Windows,enabled%20preference%2Fflag%20to%20False)

Windows has feature that displaying media control popup on its lock screen. Firefox has an option to turn this off via advanced setting, but turn "media.hardwaremediakeys.enabled" to "false" doesn't stop showing it up.

Also, on certain website (in my case tweetdeck), control screen of previously viewed and closed video is keep showing up and can't erase it unless restarting browser.

I asked this question on Microsoft forum but suggested it's Firefox issue. Does anyone have same problem? How can I fix this?

Is there a way to disable the new tab button's container context menu? The menu pops up when the new tab "+" icon is right clicked, as well as when left click is held down for one second on the "+" icon. I've disabled everything in about:config that contains the word "container" and that did not remove the context menu. I do not use containers and do not want that context menu popping up when I accidentally do one of the two things that trigger it. I've included a screenshot of what I want to disable and circled it in red.

Firefox version 106.0.1

Thanks!

Hello everyone, I wrote an add-on for my own personal use. I don't intend to publish it. So naturally, it isn't verified, but I trust it. I am able to install the add-on as a temporary add-on under about:debugging, and it works as intended. The manifest file contains "browser_specific_settings": {

       "gecko": {
           "id": "example@example.com"
       }

} I would now like to install the add-on permanently. So I packaged it as a zip file. The zip file contains the files directly without a parent folder. Under about:config I set xpinstall.signatures.required, xpinstall.whitelist.required and extensions.langpacks.signatures.required to false. Then I went to about:addons clicked on install add-on from file and selected the zip file. I got the error message: "This addon could not be installed because it has not been verified". I am using Firefox for archlinux, version 112.0.

What am I missing? How can I install this addon?

I apprechiate your answers.

I just installed firefox on a linux machine, and spontaniously, I keep getting a message pop up toward the top of the screen saying: "To play videos, you may need to install the video codecs".

This occurs when I am not even trying to play videos. I can play youtube videos fine. I don't need to install anything. It normally occurs when I am checking my outlook email, but can happen at any time.

So my question is, how do I stop this message from coming up? Prefereably WITHOUT installing some codec that I do not currently need.

Another message that comes up is an offer to install an outlook extension to my browser, but this is triggered by opening outlook email. I have no need for this either, so it would be nice to get rid if this message popping up as well.

Thanks

I am reinstalling Windows\Firefox, and would like to hide\remove Bookmarks Toolbar & Other Bookmarks, as shown on the images. The Delete Folder option is greyed out for both, and Other Bookmarks is empty.

Both were hidden\removed in my original installation, but I can't remember how I did that. I've seen posts mentioning e.g. browser.toolbars.bookmarks.2h2020 (it doesn't exist) in About:config, right-clicking on the Other Bookmarks and uncheck it (it doesn't exist).

I'm using Firefox 101.0.1 (64 bit).

Hi,

I'm on an a pretty old Linux Xubuntu pc, but with the latest FireFox. In a profile I regularity use I unchecked the Title Bar checkbox in the Customize Toolbar screen, but then FF crashed and I can't get that profile opened again. I can still open other profiles (because I still use the old-fashioned profile manager and don't need to go into about:profiles), but when I open that particular profile, after some hangups, I only get FF in the taskbar, but no screen opens so I can't change the setting back again.

Is there a file in the profile folder I can edit or something like that to enable the Title Bar option again to see if that profile wants to open normally again?

In case that's not possible I can copy that particular profile into a new profile, but then I will undoubtedly also copy the title bar setting, which I don't want. So can I copy the profile except for the one file with that setting and use the file from the new profile instead? What file would that than be?

I hope someone can help me out. Thanks in advance for any help.

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?

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Cor-el (?):

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided.

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

Which file/s contains only the browser settings, not including the extensions, which are transferable to other profiles? prefs.js? the contents of the settings folder?

How do I turn off web translation permanently for ALL pages in Firefox 118.0.1?? It´s the most annoying feature so far from Firefox. Even if I delete all languages in preferences, it shows up on every page I visit.

Running WIN10. I have used FF w Google for about 20 years, and always had new searches open in same window, new tab. Following recent refresh of FF, that seems to be not possible. Links open in new tab, but not searches. In about:config the browser.search.openintab setting is True

I have closed and reopened FF, and closed and reopened WIN10.

What might be over-riding this? Many thanks!
