Firefox optimization

[Himura2la]

I tried to use ungit in Firefox 74.0b9 on Windows 10 and found some UI bugs:

1. When you hover a commit on the current branch, the new arrow appears near the old arrow (the old one does not disappear)
2. When you delete a stash, it does not disappear
3. When you hit F5, it shows the "Whooops" page for a second before refreshing

I can reproduce 3. but not the other ones. Can you please share a screenshot for 1. and maybe 2.?

I guess the other problems were caused by https://darkreader.org/
Did not notice that it was working
Anyway, the styles should not change the behavior
