Rectangular tabs with "Round corners" option activated

[Steami]

Hello,
in my themes I applied the "Round corners" option by setting it to the maximum to have the address bar and search bar rounded. However, this also rounds the tabs, which I would prefer rectangular instead. Can anyone suggest a way to achieve this result (CSS?)?
Thanks

P.S. I am posting here again as I previously posted in the wrong section.

Simply use

.tab {
    border-radius: 0 !important;
}
