Updated to Firefox 152.0.1 and I've noticed about:privatebrowsing now has a very bright garish (subjective) purple background; I'd like to replace this with something else.

Here's what I've tried so far:

• Adding the css in this 2023 reddit post to my userchrome.css
• Fiddling with about:config, per Ty and James' replies in this similar 2022 question
• As a sanity check, directly editing the style element of the body tag in the inspector to check if `background-color: #424242` the css works. (obviously doesn't stick, see first point)
• As a second sanity check, changing the colour in the userchrome.css to fuchsia, as I'd read in older articles there'd sometimes be a flash of colour before something else was applied and bright pink is easier to see than grey
• Changing the Firefox theme from System theme (Auto) to Dark, Light, and then Firefox Alpenglow to see if that would change the background colour (it doesn't).

I do see that Alpenglow theme now matches about:privatebrowsing shockingly well, but it's not my preferred flavour of utilitarian blacks/dark greys.

Tried to show what I'm after, screenshot of about:privatebrowsing in a split view next to about:newtab. Other than above, the only other things in my userchrome.css are some styles to attempt to return curvy tabs edges.

How do I get rid of that new sidebar, the slim section? It is totally wasted space! I just want my bookmarks there without that sidebar taking up real estate. It is totally useless for me! Sometimes you just need to leave things alone.

The Firefox main screen has about 2" of space on 3 ides. The icons are so far down (the 4th side) that I cannot read the second line without moving the page up. Many of the web sites I load are off kilter, mostly NYT and Facebook games which always have to be adjusted to a place where they are on the screen correctly. I have spent several hours searching through forums, resetting , refreshing , changing zoom, you name it. I then repeated the process with Gemini, at which point it seemed I only Made the Google search bar smaller but by now I m not even sure.

the resolution offered to my earlier question about removal of logo did not help and the youtube video also did not help. What am I doing wrong? Please consider me a tech 'idiot'.

Hello,

In Firefox (up to date), the “module” (right-click) that allows for direct translation is great, and I want to thank you for it.

However, do you plan to keep the “Windows 98-style” stamp-like format of the dialog box that opens for much longer? In 2026, on 27-inch screens, it’s honestly very annoying—even if you can zoom in just a tiny bit, it’s a pointless step and not ergonomic at all! It’s the little details like this that make us look elsewhere!

Thank you in advance for your understanding!

Greetings...

I successfully deleted the new weather widget that appears at the top right of my Firefox homepage but the horizontal space at the top of my homepage remains. I followed all of the steps (3) to delete the weather widget but none of them also deleted the horizontal space. As a result, there is a wide white top "margin" that appears on my homepage, below which the customary Firefox graphic logo appears.

On my Firefox homepage, I have three rows of shortcuts that now appear lower on the homepage and a vertical scroll bar now appears on the right side of the homepage. Before the new weather widget appeared on my homepage, the three rows of shortcuts were vertically centered on the homepage, without the need for a vertical scroll bar to appear.

Either there is a way that the horizontal space at the top of my homepage can be deleted, or I will have to resort to creating a custom HTML webpage containing my shortcuts.

Please advise which solution will resolve this problem. Thank you very much for your time and feedback.

Take care...

I found on a browser search that setting icon means there are customizable features available. I updated to latest version of Firefox but have no idea what other features are available to customize. Too many setting options to go through every one. How do I find out what I need to do to get the settings icon to go away.

I want to change my " theme" to "full black" but i cannot get it to switch. I want a black backf=ground but can't change

Any suggestions would be greatly appreciated

Since updating to version 150 (and 150.0.01) my title bar is missing. Sure, I CAN get it back with F11 (2 times) but it is annoying to have to do that every single time I start FF.

There is no longe an option (to checkmark or remove checkmark) in the right-click menu to show the title bar. (it used to be an option) I want the option to have it there permanently, or not. It should be up to me, not some dev somewhere that does not like it.

How do I get rid of the VPN icon and other crap that you put on my machine? I do not want VOIP, will not want it tomorrow, and would prefer not to waste space on my screen to your ad.

Up until a few days ago, whenever I opened Firefox a right-side sidebar would open with the bookmark directory - including all bookmark folders visible at all times. Now I can't find how to do that. Instead there is this awful hover feature that has a VERY clunky and time consuming way to find an individual bookmark. How to change back to the prior method? Can I revert to the prior version of Firefox? Thank you!
