Hi, I updated to Firefox 146.0 this past week and immediately noticed that the UI elements (scrollbars, sidebar, tooltips, etc) are once again in dark mode; the main websites window and the firefox settings remain in light mode (as set by my user preferences). I've been using browser.theme.toolbar-theme and browser.theme.content-theme to force light mode of all UI elements regardless of theme and as of this last update they have stopped working (editing them to any value of 0,1,2 does not make a noticeably change to the UI). What internal setting changed to stop firefox from using the browser.theme.(etc) settings and what can I edit to get them back? Thanks, Bre

My Bookmarks Sidebar is now displaying with white lettering on a very light gray background, making it almost impossible to read. How can I change either the font color in the sidebar, or the background color?

As the title says , im really hoping for a small change that will happen from Firefox team or an addon , since i started using vertical tabs it was the best thing ever happen. however im really just hoping to have the option to increase the icon size of the tabs, i usually just have the icons showing without the name of the tab thing, but my only need is just to have the ability to increase the size of the icon tabs thats it

In the previous version of Firefox, my Bookmarks folder was fixed in to the Sidebar so that when Firefox opened the Bookmarks were visible; how do I fix the problem?

Hi everyone, I just set nice custom colors for the websites. Problem is, not every website looks good then, on some it gets messy. Is there and option somewhere to toggle it off, for particular websites, while still keeping the setting on for the rest of the internet?

Best wishes, Techno

Firefox Sidebar view only shows a 'Search' window and no Bookmarks or History lists

I have never had this problem before.
I can still view Bookmarks or History but only if I select it.

Incoming messages on Firefox display is quite small as compared to Microsoft Edge and I cannot seem to enlarge as I do not see a "zoom" icon. When

I highlight the words, they are Arial font size 14 but visually they are not.  How do I zoom and default the window size? Here is a frame shot.

The scrollbar slider isn't displaying correctly. If I grab the screen, zoom in, and look very carefully, it is possible to see that the slider is a very slightly different darker shade of grey to the rest of the scrollbar, but it's almost impossible to see, so something is clearly not working properly here. The scrollbar should be highly visible as it's the most often-clicked control of the entire browser.

When using vertical tabs and having bookmarks toolbar only visible on a new tab, there is this behavior where if you are on a website (bookmarks toolbar not visible) and then open a new tab, the vertical tabs move because they need to make space for the bookmarks toolbar. Would it be possible to make it like it is, for example, in Microsoft Edge, where when you open a new tab, your vertical tabs do not need to move because the bookmarks toolbar is as if off to the side a little bit, so the vertical tabs do not need to provide extra space for it? My hope would be for the bookmarks toolbar to be next to the vertical tabs, not above them.

How do I disable the cruft which appears in the URLbar? Specifically, the trackers detected symbol, the certificate verified symbol, the bookmark this page symbol, and the question mark symbols which appear on both the URLbar and the searchbar.
