Firefox Community Forum

I cannot change the background image when my Firefox app opens on my MS Windows laptop. During set-up, the system had me select an image, but I want to change it as I find it distracting. Thanks!

I opened Firefox this morning and all of my pinned shortcuts have disappeared. Shortcuts are enabled in the settings. I checked the browser.newtabpage.pinned pref on the about:config and all of my pinned shortcuts are still there, but they're not appearing on the actual page itself. Are there any other settings that I'm not aware of?

I deleted all the shortcuts from Firefox desktop browser's homepage and now I cannot add them back.

There are no blank shortcut icons on the page anymore. No setting to enable them. Shortcuts are enabled. Page is mostly blank, only has Firefox icon.

I tried to close and open Firefox as well as disabling and enabling the shortcut setting. Adding more rows did not do anything.

Before this issue occurred, I had one shortcut on the page that was linking to localhost. I opened the edit window to the shortcut and pasted the same address and saved changes. After that I removed the shortcut. All of the blank tiles immediately got removed from page and I had no way of adding more shortcuts.

I'm on Linux.

I've been using this method to setup a custom new tab page for Firefox for almost 4 years, and it has worked great: https://jamesnorth.net/knowledge-base/article/firefox-new-tab-page

Navigate to /usr/lib/firefox.

Create autoconfig.cfg:

// var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

/* set new tab page */ try {

 Cu.import("resource:///modules/AboutNewTab.jsm");  
 var newTabURL = "file:///home/james/ff/index.html";  
 AboutNewTab.newTabURL = newTabURL;  

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

Create defaults/pref/autoconfig.js:

// pref("general.config.filename", "autoconfig.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false);

However, upon updating to Firefox 136, I only get a blank page. All of my autoconfig files still exist in /usr/lib/firefox.

When I create a new tab with Ctrl+T, it's a blank page. When I create a new window, it loads the local page I want it to load with the file path in the URL (which it never had before; the URL bar was blank in Firefox 135). So it seems to be partially working.

Any tips?

This has been asked before here, but it seems currently there is no solution:

Firefox's default behavior when using the mouse middle-click on an empty area of the tab bar area will create a new tab; I don't want this behavior. How can I disable it?

On the posts I found here, they mention using UserChrome.css, I enabled it and tried, doesn't work. custom styles are enabled but not disabling this feature.

I use DisplayFusion on my multi-monitor setup since years, and middle-clicking a window title bar or Chrome tab bar or Firefox tab bar will move the current window to a second monitor.

Currently with Firefox, middle-clicking the tab bar will move the window to the second monitor AND open a new tab. I use it a lot with YouTube, so when I move a playing video to the second monitor, I get an empty tab with audio in the background.

I recently moved from Chrome to Firefox, but this is driving me crazy.
