Recently, I downloaded a userChrome file to make Firefox resemble an old version of Google Chrome. Everything looks pretty good so far, except for one issue: part of the first/leftmost tab always gets cut off, as you can see in the first attached image. What I want to do is add a small amount of blank space or padding to the left of the first tab so that the full tab is visible, sort of like what I have in the second image (I took that image by dragging the tab manually, which I obviously can't do while browsing). I ''also'' want to shift the rest of the tabs to the right by the same margin, so that I don't mess up the overlap pattern. How do I do this? For reference, I'm running Firefox 84.0.2 (I just changed the browser icons and website favicons with resource hacker).
