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.

For tab settings I have checked these: Open links in tabs instead of new windows When you open a link, image or media in a new tab, switch to it immediately

In the past links opened in new tab immediately. But now some links open in SAME tab immediately. For example: I open https://www.pbs.org/livestream/ and start watching the livestream. When I click the link On Air Schedule It opens immediately in the same tab, which ends my livestream

Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over. I can access using Chrome. How can I access without changing from Firefox?

Apparently Firefox did an update (version 136.0.4) in the background while I was using Firefox on March 27. At some point I wanted to save a page to my bookmarks and realized all my bookmarks were missing. I had just used bookmarks earlier, so it had to have been an update. This happened to me before back in January 2025. I was without my bookmarks for several weeks when all of a sudden they showed up again.

I cannot use the instructions to go back to a previous profile, as the two options showing do not have my bookmarks, bookmark toolbar or customized Firefox homepage. I also cannot import my saved bookmarks to get them back. I get an error message when I attempt to do that option.

This is very frustrating, as I use my bookmarks, toolbar and customized homepage EVERY day. I have all my important links saved to bookmarks. Firefox developers need to find out why an update removes bookmarks, as this seems to be an ongoing issue with me. I've used Firefox for over 17+ years and never had bookmarks removed after an update before, so something in an update is causing this issue.

I have no idea at this point IF everything will return to normal in a few weeks like it did back in January. So right now I am without all my bookmarks. Please get this ongoing issue resolved, it's a royal pain. I need those bookmarks to maintain my daily routine for accessing financials, medical websites, etc.

Thanks for any help you can give me at this point. This is the second time it has happened.

My "Pearls Peril" game is unable to open for past week. I've tried checking and rechecking Firefox (not my default browser) where I've always played "PP" and "JJ". "June's Journey doesn't completely fill the screen; there's a red band about an inch thick.

Help me return to correct settings in Firefox so I can enjoy playing "June's Journey" and "Pearl's Peril"(which isn't opening). As I explained in my question, there's a wide band across top of "JJ" game which appeared, as well. 

 About one week ago, I was trying to re-set use of my debit card, was unable to as I'd probably severely cancelled it 6 months ago. I don't have a clue as to what the connection between these two activities have to do with each other but it's all I have to go on.

Thank you for any help! I've asked Wooga to give me some steps; I tried following them but Pearl Problems continue to plague me.
