I-Firefox Community Forum

Does anyone know where Mozilla wallpapers are stored? I wanted to set a wallpaper from Mozilla's menu as the desktop wallpaper on my laptop. I looked for hidden files and checked the forums, but I can't find them in the given locations e.g. my profile. Maybe these files are masked somehow. I'm looking for particular wallpaper from the abstraction category (screenshot). Can anyone tell me how to find it?

Hello

Recently I've upgraded from Kubuntu 24.04 to 24.10. I'm almost sure that the minimize/restore buttons were available in my Firefox after the system upgrade. For the last few days I can see they are missing - please see attached images.

I can partly fix the problem by going to Settings->More tools -> Customize toolbar and selecting "Title Bar" checkbox. In that case I have the title bar displayed with all 3 button (minimize, restore, close).

But I would like to have the default behavior: title bar is turned off and the mentioned 3 buttons be visible in the tab bar.

How to have those buttons in the tab bar when the title bar is turned off?

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

I'm trying to add the zscaler certificate (my company uses it) to firefox using the certificate manager. When i select the certificate and click import, nothing happens. The certificate doesn't show up on the list of authorities and there are no error messages.

I'm using firefox in a VM running Ubuntu btw and the certificate I exported from the host machine running Windows.

How to shrink this vertical space? (see attached image)

Ever since 131.0.0 my shortcut icons got all messed up so I am trying to restore the original look. I've already removed the giant Firefox logo and made my icons larger. Now I need to condense them so I don't have to scroll to see them all.

Here's what I have so far in my userContent.css:

/* Minimize the size of the logo and wordmark on the Home/New Tab pages */ @-moz-document url(about:newtab), url(about:home) {

 .logo {
   background-size: 0px !important;
   height: 0px !important;
   width: 0px !important;
 }
 .wordmark {
   background-size: 0px !important;
   height: 0px !important;
   width: 0px !important;
   margin-inline-start: 0px !important;
 }

 /* Expand the shortcut icon images to max size on the Home/New Tab pages */
 .top-site-outer .tile .icon-wrapper {height:100% !important; width:100% !important;}

}

There are 4 toolbars at the top of the Firefox screen. The default order from top to bottom seems to be:

 Menu bar
 Tabs bar
 Navigation bar
 Bookmarks bar   (which Firefox apparently calls "PersonalToolbar")

I would like to move the Bookmarks bar above the Tabs bar so the order is;

 Menu bar
 Bookmarks bar
 Tabs bar
 Navigation bar

I tried to use ChatGPT to accomplish this. After well over 6 iterations, I gave up (ChatGPT was still going strong - hallucinating?). The only code in userChrome.css that accomplished this is shown below. Unfortunately it leaves the order as:

 Bookmarks
 Navigation
 Menu
 Tabs

Can a human expert help me where ChatGPT failed? ___________________

/* Move the bookmarks toolbar above the tabs */

1. navigator-toolbox {

   display: flex;
   flex-direction: column-reverse;

}

Hello,

I'm a bit out of ideas how I can get Firefox to display the correct characters. For reference: https://learnjapanese.moe/font/

Windows: I only have german and japanese locale installed, i even changed in intl.cpl the language to japanese. I have installed the japanese language pack / fonts and it's showing correctly in any windows editor.

Firefox: Second language set to japanese, disabled all addons, tried it on private mode to no success.

Any ideas how I get the characters to display?

Edit: I made it work by changing in about:config the font.cjk_pref_fallback_order-string to have ja as first.

Hello,

I use Firefox for Mac. When I click on a link to a map, I get a message to open the link in Apple Maps, installed on my computer. Is there a way to make Firefox open the link in Google Maps in the browser? Here's an example, the link is at the bottom of the article: https://sfstandard.com/2024/10/17/hunters-point-gantry-crane-illumination/

Thanks for your help

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.

How to change home page and new tab to desired URL or any extension of Firefox desktop in 2025?

I am unable to find any way to change how my new tab should look when I click + sign or new tab is opened up on browser opening or re-opening unlike Chrome.

I hate the change of position of typing from the search bar on the current new tab to the URL bar (unseen or unheard in Chrome) that Firefox implemented without considering users who would detest it.

Using Firefox 131.0.3 (64-bit)

Firefox 139.0.1 (64-bit) on Windows 11

I occasionally increase the zoom level of websites (usually forums) with Ctrl+mouse wheel if the default text size is too small. However, if I forget to set them back to 100% (Ctrl+0) before closing the tab, the next time I open that URL, it's at the former adjusted zoom level -- not 100%. Really annoying.

How do I force Firefox to open all URLs at 100% regardless of the last custom zoom level? I have default zoom already set to 100% in Settings and Zoom Text Only is not enabled.

Thanks.

Hello,

It's been a while I wanted to try vertical tabs and now is is possible with FF. I was wondering if it is possible to merge the two top rows when using vertical tabs ? (The address and buttons row and the Windows, minimize, resize and close row).

When using horizontal tabs, the top row (minimize, resize and close row) is merged with the tabs row. But when using vertical tabs, you can a "useless" row that takes almost as much space as the horizontal tabs row, so vertical tabs doesn't make you gain that much browsing space.

Thanks

The latest version of Firefox (115) always launches at fullscreen size in linux. I rarely use any application at full screensize because I like to have other windows open on the desktop at the same time. Virtual desktops are not always convenient. I have tried using the -geometry option at the command line, which is usual honoured by applications running under X11, but this is ignored. Nor can I grab the bottom right-hand corner and drag it diagonally to resize it dynamically. Maybe there is a setting somewhere for initial size?

I suspect Firefox Relay is not allowing me to sign into a site on the internet. Following instructions I put the Relay Dashboard in my Firefox Settings or so I thought. How do I locate it?

After the 139.0 update, I noticed 'Firefox Labs' is missing on my settings page. I checked the config and saw: browser.preferences.experimental true

I have telemetry checked Send technical and interaction data to Mozilla This helps us improve Firefox features, performance, and stability. Learn more

Once in a while the 'Firefox Labs' will appear momentarily then disappear.

Any ideas son why this is happening?

Hello, how can I remove or hide "List all tabs" btn?

Set "browser.tabs.tabmanager.enabled" as "false" stopped working for me after update to version 131.0. Hiding the btn before version 131.0 was not a problem.

I saw in release notes that "List all tabs" got some changes. link
