Ability to Right Click Tab (as one does to Pin) / choose Colorize-Trans / 9-20 available colors (millions-color picker?) / Tab stays in location.. but is colorized and set to transparency of that available on color tab transparency slider....Improving 1's "Performance", as well as 1's brain "connectivity" of finding tab desired... Instantly. (identical to tab groups BUT for unnested tabs outside of group/ nested tabs in group 2 have ability 2 colorize/trans b handy as well) Thnx (move to appropriate forum/support/requests link as needed)

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

When I select Dark Theme, I DON'T wanr to see this. I just noticed this on my Linux Mint desktop machine tonight when I logged in. I also have Dark Reader installed and it isn't affecting ioit eitherit either. Make this go away. It burnsssssss!

Very often it happens to me that I'm not able to tell whether I'm at the beginning or at the end of a document. The scrollbar colors displayed by Firefox do not provide enough distinctive information to tell. (See images attached.)

From the 80's 'til the 10's we had 3D scrollbars with outset borders giving the impression of a raised scrollbar … for a reason.

Is there a setting to have Firefox display 3D scrollbars on Windows?

I am experiencing a weird scaling issue on one of my monitors with Firefox. The whole firefox window looks as if it's scaled to high resolution mode. Not just zoom of the content, but the whole window, including the title, toolbars, etc.

Note that only happens on ONE monitor (I've tried this on total 6 monitors now), and it happens only on one Firefox Profile. If I use a new profile, the issue is gone. However, if I copy the profile folder to the newly created profile, the issue comes back.

Here is a screenshot of the two windows opened at the same time on the same screen. Right window is normal, and the left window is the scaled up version.

I don't want to re-create my entire profile if I don't have to. Does anyone know what kind of setting/feature did this and how can I revert it? Since it does not happen on a different profile, and is replicable by copying the profile settings, it must be some kind of a firefox setting somewhere.

After update to 141.0.3(64bit), sidebar comes with waste space, as pink area in attached image.

It didn't shows in these years I'm using FF, I want to remove it but keep sidebar exist, like it was before. Where can I adjust it ?

If it's needed to be exist, why not put it on top of Sidebar ?

Dark mode in Firefox has broken just now. The issue appears restricted to Firefox - all other elements in environment (Ubuntu/Cinnamon) appear to be operating correctly.

The elements at the top of the screen and some menu screens are now white rather than dark grey. Due to a neurological condition this causes near-instantaneous cluster migraines.

Is there a way I can fix this? Is there a way you can fix this? Is there a way to access the web without a browser? (eg through the text terminal)

the last couple days my bottom bar has disappeared when im looking at you tubes or websites, so i can't change screens to check email, or access speaker selection... changing magnification doesn't help. escape key doesn't work to reduce size and see the bottom bar.. so annoying... is this windows trying to force me to give up on windows 10 or is it something i can solve on firefox.?.... im 78 so that tells you what level im at with solving this myself lol....

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.
