Firefox Community Forum

If letterboxing (anti-fingerprinting) is used or when a webpage is smaller than the window (such as in about:config), Firefox fills in the rest of the window using a dark gray. I want to make it completely black.

This is what I currently have in my userContent.css

```CSS @-moz-document url-prefix("about"), url-prefix("chrome"){

 body{ background-color: rgb(0 0 0) !important };
 .sticky-container{ background-color: rgb(0 0 0) !important };
 #toolbar{ background-color: rgb(0 0 0) !important };

}@-moz-document url-prefix("about"), url-prefix("chrome"){

 body{ background-color: rgb(0 0 0) !important };
 .sticky-container{ background-color: rgb(0 0 0) !important };
 #toolbar{ background-color: rgb(0 0 0) !important };

} ```

Is there a way to show bookmarks on particular sites without showing them all the time?

My use case is that I have a plugin's url set as my home page and new tab page and would like to be able to see my bookmarks when I open a new tab but not when I'm on other tabs.

Bonus question; is there a way to have my new tabs open to that plugin's url but also have the url bar empty for browsing?

Thanks in advance for any help with either of these I imagine specific questions.

Dear sir or madam,

Can you please help me with a deeply frustrating problem I'm having with Firefox? After the last update, the shortcuts on my FF homepage disappeared and I can't restore or rebuild them.

Under settings, the homepage is set to show two rows of shortcuts but none are visible. I changed it to show more rows, closed & restarted FF, but no shortcuts appear. I then changed it to no rows, closed & restarted FF, then set it back to two rows, closed & restarted FF - still no rows. I've tried starting FF in troubleshoot mode, but to no avail. Looking through the Community Forums, I can't find anything that directly relates to my problem. In case this may help, I've had this problem once or twice before but I'm afraid I can't remember how it was resolved or if it was anything I stumbled upon that fixed it.

The environment is FF version 136.0.2 (64-bit) on an Acer Aspire E5 PC running Windows 10 Home, 64-bit, version 22H2, last updated 16 March 2025.

If you can offer any suggestion how I can resolve this and stop me pulling my hair out (in my case, it's an endangered species!), my remaining hair and I will be eternally grateful.

Yours faithfully, Peter Palmer

Is there any setting that allows to get rid from this annoying Titlebar (line with buttons) in fullscreen mode? So that it never shows up even when hovering the mouse pointer over the top edge of screen. When it jumps out everything slides down and always leads to miss clicks when I try to select tabs. I don't want it to be constantly present here as well because it takes up screen space.

Bought a new monitor which is set to 3840 x 2160 by default, so i had to change the Windows UI display setting to 200% for my eyes.

This is fantastic on Windows and works as expected with Chrome and Edge browsers. Type appears to be correctly anti-aliased. It does not work with firefox, however. Both the browser UI and viewport content is pixelated.

Attached are three examples of the pixelation on text that we are seeing.

There is no scaling set within the browser - this is a new install with everything set to default at 100%.

Is there a system setting that we need to invoke in order to smooth type within the viewport. There are several articles on this forum that seem to touch on type smoothing but we were looking to confirm whether there is a default setting that can be changed outright.

My Firefox toolbar used to show the address box, and at the end of the address box was a search box. After the last update, the search box disappeared and I would like to get it back. I used it constantly because it would hold my search and if I needed to tweak it a bit, it was still there and easy to do. Now I have to type the search in the address box and it goes away immediately. There was also a drop-down that listed my last few searches. The address bar goes almost completely across the page. Is there a way to get my search box back at the end of the address box? Thank you.
