Edges of FF Browser is way, way off. I have several screenshots of this. The only way to correct the issue is to minimize and maximize, + or - the Browser until it snaps out of it. I'm going to restart my system in a minute here, to reset everything. Issue has gotten slightly worse this past week or so.

I use Firefox quantum 66.0.1 64bit on Linux Mint 64 bit on 24" screen PC with newer hardware. I use Chromium occasionally and I have not seen this border issue there. FF Browser seems to only do this when I use it on a Linux system, haven't seen this issue yet on windows. I have wondered if this issue is related to me using very large displays. I use a 24" screen.

This particular problem doesn't bother me much, but I thought I might say something.

Thanks!

OK. I went in to each of my profile folders and made the changes as you described. I deleted each xulstore.json file. then I started the browser. It seems to have done the trick! Thank you.
