Hi there! The New Tab page looks great with white text, but Firefox 140.0.4 thinks my wallpaper is white, so text should be dark. I can change the body class to "activity-stream darkWallpaper" using the inspector and it works fine, but how make this change permanently?

Hello, after ff updated, gray line appeared. It does not disappear after changing theme. I am using laptop and a monitor. On laptop browser window goes fully to the top, but when i drag ff to the secondary monitor, gray line appears. I will attach photos.

It looks an update occurred but now my bookmarks Column has a white background with white type. I can't read anything there because its all the same color how do I change the background to black?

During the week of March 7-13, 2026, upgrade(s) caused the size of my bookmarks, fonts and tabs to shrink to barely readable (see attachment) in the Firefox browser window on my Windows 11 PC. I've tried every internet base advice article. How do I increase the size of them?

I use the Firefox Search bar a lot (the one that has a magnifying glass). The latest version of Firefox's Search bar seems different and the magnifying glass has been replaced by an icon of my default search engine. Although the old and new Search bar are very similar, the newer one has a larger font, and the search options on the drop down menu have a magnifying glass next to it. It also takes up more space on the browser (not as packed) which I don't like as much. Is there a way to revert to the previous version of the search bar? The first pic is the new search bar and the second is the older version.

How do I enable syntax highlighting when viewing the mark up of a web page, using the "view-source" functionality of the current tab.

It no longer works for me, I need to use this feature so I can find errors in my HTML markup.

Does the "view-source" feature have any optional settings available to the user and how do I find them using the about: option

TIA.

Since a few months ago the newtab page layout has been changed. The site icons are now smaller, leaving a wide margin on the page. In my opinion this margin is too wide and looks strange. Is there any way to change it back?

See the OLD and NEW layout in the uploaded images.

My address bar disappeared. I can get it back by hitting F10 but it doesn't stay. How can I get it back and keep it? When I go to the Customize Toolbar setting, the address bar is not there.

My toolbar is visible when I click on the 'Open a new tab' plus sign at the top. But if I go to a site, either from a search or from bookmarks, the toolbar disappears.

I just (yesterday) had to delete profile, delete bookmarks, delete Firefox, install Firefox, in order to get it where it would save bookmarks again. The toolbar, prior to that, did NOT disappear when I went to a new site.

Please help.

Dear Firefox Team,

I hope this message finds you well. I would like to suggest a small but useful enhancement to the Firefox interface that I believe would improve user experience and accessibility.

Currently, in the "Customize Sidebar" section, the available tools are limited to a few items such as AI Chat, Tabs from Other Devices, History, and Bookmarks. I believe it would be very helpful to include "Downloads" as an additional sidebar tool.

This would allow users to quickly access their recent downloads without needing to go through the menu or use shortcuts. It adds convenience and aligns well with the purpose of the sidebar — offering quick access to frequently used features.

Thank you for your time and for continuously improving Firefox. I look forward to seeing future updates! Warm regards, Julabeeb a firefox user, developer, and contributor
