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 };

} ```

I'm trying to setup a new laptop and when I try to log in I enter my password, I get my email with my 2 factor code, enter it and then it kicks me back to the password screen saying "Incorrect password" . I've reset the password a few times and still get the same behavior. Am I only allowed to have 1 device logged in at once? I know in the past I was able to have multiple computers logged in.

I have two monitors: Monitor 1 is Asus PG248QP(Run in 1920 x 1080 360hz landscape 100% scale) Monitor 2 is G272U Pro(Run in 4320 x 2160 60hz landscape 150% scale). I arrange them veritcally, monitor 2 on top and monitor 1 at the bottom.

When I minimize the non-fullscreen firefox window on the monitor 1, black/transparent border shows on the left, right, and bottom of the firefox window.

When I arrange two monitor horizontally, everything normal. I place monitor 1 at the left of monitor 2.

When I do this on the monitor 2, everything normal.

I have to use two monitors vertically, since I don't have much space.

I also tried different versions of firefox. for now, 129.0 to 136 has these problems. I have install chrome, brave, edge. None of them has this problem.

windows 11 23h2 (22631.5039) cpu: 13900k gpu: 4090 with 572.60 ram: 32gb x 2

Firefox 137.0

already tried refresh firefox profile.

I have a typical search bar at the top of the browser window. Recently, as soon as I begin to type a search, the bar expands to cover the whole top of the browser window. How do I stop this from happening? It's unnecessary and irritating. Firefox 133.0, Win 11

Last year, I never could get the info in to register, but it did let me do my taxes on it. I hope it lets me do mine this year. I really need to get it done, I have more to do than usual. While I was writing I saw someone ask if Mozilla and Firefox were the same, but I did not see the answer.

I recently purchased an IMAC 2024 M4 running Sequoia OS computer and migrated my files from my old IMAC. I have been using Firefox for over 15 years without at problem. Now I cannot open often visited sites like my bank, American Riviera Bank, Craigslist and others. I just get a blank white screen when attempting to access the website. The same ones are fine on Chrome. What has happened here and how do I correct this - Its really making me crazy. Thank you, Richard Houser
