I noticed that my Tab background color doesn't change after recent Firefox updates.

I have this code (css - chrome) to change the color of the active tab to green and it no longer working.

/* Start code: Change color of active tab to Green and the inactive to default*/ tab[selected="true"] *{ background-color: #00c100 !important; /*Green */ font-size:10pt !important; font-weight: 650 !important; color: black !important; }

Any help in fixing this is appreciated. Regards,

I use the setting brower.search.widget.new = false to customize my search bar. Since the latest update of Firefox (Firefox 154), I noticed that spacing between search results is larger and I don't like it as much. I am hoping to revert to the previous version where the spacing is more tight and easier to navigate. The first pic is Firefox 154 and the second is a previous version (147).

I have switched off the "story" but want to get rid of the overlay for this. How can I do this. It is visually offensive to have this big gray blob in the middle of my screen. I have been loyal for firefox because I do not want this kind of intrusion.

I have two installations of Firefox on a desktop and a laptop. The first installation is pinned to the Windows toolbar and the 2nd installation has a shortcut pinned to Windows Start.

When I saw that the latest update of Firefox to 154 allowed changing icons, I changed the 2nd installation to a different Firefox icon (mini-fox with black background) so it was easy to see which installation to use when both were open.

The problem is the changed icon for the shortcut is wrong after shutting down the computers. I do not recall having this problem with the 1st installation or on my 2nd laptop where I only have one installation of Firefox.

I suspect this is just a glitch that will likely be fixed in a future update, but it is annoying to have to go through the process of changing the icon every time I startup a computer. If anyone has found a solution for this, I would very much appreciate your help.

my firefox auto updated to a new format, where all the text and bookmarks are forcibly spaced as if I were writing a double spaced essay. This has cut down the maximum number of displayed icons severely in book marks

As described, I (changes being intended as temporary) changed the maximal size for the sidebar to open upon hover. Only when, at that length, I try to revert the change, the sidebar closes before I can "grip" the edge of the sidebar to shrink its length.

My issue is not that I cannot fix this change. My issue is that my change isn't permenant. I followed the standard steps of "Right-click anywhere on Sidebar > select 'Customise Sidebar' in menu > let Sidebar collapse > in 'Customise Sidebar' panel deselect 'Expand sidebar on hover' option > close 'Customise Sidebar' panel > pick up the RH edge of now stationary Sidebar by hovering mouse until the 'gripper' symbol (double-headed arrow) appears... drag RH edge of Sidebar to desired new max-open width."

The issue is that, after doing this, the sidebar reverts to taking up half the screen once I re-enable "Expand sidebar on hover" and reversing the steps listed above.

Any help would be appreciated! I'd rather not have to re-install.

Today all of a sudden the size of tabs, toolbar, and sidebars on Firefox became so tiny that I cannot read them anymore. And although I can adjust the font size of each page I cannot do the same for the tabs, toolbar and sidebars. It has become unusable to me this way. I need a magnified glass to see what tabs I have open, to search or access the toolbar and sidebars. I hope you can tell from the screenshot how tiny they have become. Please help.

The mouse cursor does not highlight text in the address bar. It is selecting the text but the blue 'select' highlight doesn't show so I'm working blind. Firefox 154.0b5 Build ID: 20260731090442 (64-bit) on Windows 11 Home 25H2. Build 26200.8875 Tested in troubleshoot mode - same issue.

No point adding screenshots to show an invisible select highlight.  :-)

Name Firefox Version 154.0b5 Build ID 20260731090442

I do not have the function to customize my display screen to dark anymore after the last update, why? The screen shot below used to be a White on Black screen before the last update now it Black on White and I cant change it back

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.

I just updated Firefox to version 152. Now my bookmarks toolbar is broken. Can't open any site from that toolbar. Also,, the pinned sites and folders are scrambled one over the other on the left (see picture).
