FF89: Tabs have unnecessary space above them when window is maximized

epitaque commented 3 years ago

Sanity checks (must complete)

[X] I have read and followed the installation instructions in the README
[X] I have not modified the userChrome.css file
[X] I have tested the latest release for my Firefox version, or commit on master/beta branch (beta is for Firefox Beta only)

Describe the bug In past releases, there was no space above tabs when the window was maximized, they went all the way to the top of the screen. Now there's a gap between the top of the tab and the top of the screen.

To Reproduce

Open FF89 with this modification on Windows 10 and maximize the window.

Screenshots How tabs in maximized windows in FF89 currently look (notice space above the tab):

How the tabs should look (and how they currently look in Chrome):

System info

Do you have browser.tabs.extraDragSpace enabled in about:config by any chance?

Do I have to creat browser.tabs.extraDragSpace? It doesn't have this

I did have it enabled. I just disabled it, then restarted Firefox, and it still looks the same.

The toolbar of Chrome looks more compact, this theme is still a bit bigger, how to make it same size as chrome?

I've encountered the same issue in both the 89.0 and 88.0 releases. In 80.0 it was still fine.
