On macOS, I set System Settings -> Desktop & Dock -> "Double-click a window's title bar" to "Fill".

In Firefox, double-clicking the window title bar does nothing. If I change the macOS setting to "Zoom", double-click works correctly in Firefox doing Zoom effect.

I confirmed that other applications respond correctly to the "Fill" setting.

Environment: - macOS version: 26.3 - Firefox version: 147.0.4 (aarch64)

Last week I went to my Firefox browser, my main browser for years, only to find the background is a disturbing pink and all my bookmarks are gone. What happened to change my data and page...did I do something to choose a new format?

When using Firefox mobile for android, a black bar appears at the bottom of the screen, above the address bar. Please see attached picture.

It only seems to occur when the "scroll to hide toolbar" setting is disabled. The bar moves upwards when using the keyboard.

Samsung galaxy s25 Android version 15 Firefox version 147.0.3 (Build #2016141759)

Please let me know if any more information is necessary.

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

Hello. I have some questions. I want to delete the image, but I don't know how. How can I do this? I've looked into it, but I couldn't find a solution, so I came to ask for advice.

some items are large, some items are TINY. I have tried resetting my display setting scale, but the url bar, the menu where are my open tabs, the bookmarks toolbar, and some other things re TINY.

I use Firefox for genealogy research because it always keeps track of which pages I've previously accessed since their hyperlink will change color. Today, I ran Microsoft's PC Manager software and it suggested clearing the cache of Chrome and Edge. For some reason it also must have cleared the cache of Firefox since the previously accessed hyperlinks are no longer a different color. Since I had a created a restore point this morning before installing PC Manager, I restored the system to that point. Following the restore, Firefox would not open so I re-installed it from the website. I had previously backed up the profile folder and so copied that to the new profile folder of the fresh install. My bookmarks and history seem to be fine but I still don't see a color difference in the previously accessed hyperlinks. Any suggestions on how to get them back would be greatly appreciated.

Web pages that are supposed to contain emojis are blank. I can highlight where emojis are supposed to be shown but the actual images of the emojis aren't there. about:config font.name-list.emoji correctly contains "Apple Color Emoji" If it is relevant, this has been a bug/issue that has persisted for a couple of months now (can't name an exact date).

Current behaviour in fullscreen mode: When I move my mouse to the top of the screen The tabs appear and the whole website content gets shifted down. It's ugly and distracting. Desired behaviour: The tabs appear as an overlay and part of the website content is hidden underneath them. No transitions.

What css js should I modify to achive this, any help? This prevents me from using firefox in fullscreen mode and saving space.
