I have just reopened my Firefox and have found that recent changes have suddenly put my tabs right at the top of the window - initially very confusing because I feared that I had lost them. I would like to put them back where I find them easier to work with, how can I do that?

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.

Since the latest update, I can't see the text in contextual ("right-click") menus. I'm using Version 154.0 (64-bit) on Win 11 for Snapdragon. I've attached an example.

How to deal with this?

The autocomplete dropdowns for form fields have recently changed appearance, and I strongly prefer the previous, simple design.

The new version has:

• Clock icons next to autocomplete/history entries
• Much more vertical padding, making the list unnecessarily large
• Rounded "pill-shaped" highlighting when hovering over an entry

The previous autocomplete list was much more compact and clean, without the clock icons, excessive padding or rounded hover backgrounds.

Is there currently a setting, `about:config` preference or other supported way to restore the old autocomplete list appearance?

Ideally, I would like to use the previous style:

• No clock icons
• Compact rows with the previous amount of padding
• No rounded/pill-shaped hover effect
• Otherwise retain the existing autocomplete functionality

If there is no setting to restore the old appearance, could an option be added to allow users to choose between the old and new autocomplete UI?

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

August 24, 2026 Sometime during the last month website backgrounds changed to black. I can't see well with black. I did not install colorways. I had things setup as I liked then suddenly everything changed. How do I switch to a lighter background? My desktop background is a custom medium green. I tried enabling a light theme - no success. I've already tried the Windows settings for accessability. All help will be appreciated.

For some scrollables, v153 doesn't respect the Mac OS setting to hide scrollbars unless scrolling on page load. If that OS setting is adjusted after the page is loaded, then the page respects it again until refresh, so there's apparently some sort of race condition going on where it's not reading the setting in time before the page loads?

This is not a problem in v152. I downgraded back to v152 and it's working again.

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).

When entering the "customize Firefox" page, the option to enable or disable the title bar is missing. From looking at pass guides it used to be on the bottom left of the page but now it's gone. In case it matters, I am not in fullscreen mode.

As of 20 August 2026 Firefox update, my right-click menu is messed up. It USED to be black with white text; now it's unreadable gray with slightly darker gray text. Putting Firefox in "Dark Mode" brings that back, but makes everything ELSE completely unusable. I use the "default" setting under the Appearance Settings, and always have (as in really always, from the day Firefox was first available). I use "Orion Nebula Center" by Lightyear, and have done for years. Disabling it doesn't do anything as far as the right-click window. I've uploaded a screenie of the specific menu, in case my description isn't clear. I did try a Firefox "recommended" add-on called Stylebot, but it appears to work only on a specific element of a specific page, and not globally to correct the issue on any/all windows. How can I get the black background, white text version of the right-click menu back? Thanks!

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,
