Lower tab curve is missing in Firefox 102.

[CO-Windler]

I use a custom userChrome.css to render curvy tabs. Since I updated Firefox to 102 on Win10 the lower curves of each tab (except the leftmost corner) are not drawn properly anymore but stay straight.

@import url(userChrome-light_photon-australis.css); /* curved tabs */

So I won't dare to update my Linux Mint version of Firefox 101 yet. (FF102 on Win10 also introduced a cookies setting bug that risks privacy.)

Same here on Firefox 102.0 and Windows 10 21H2

Try this:

.tab-background {
  outline: none !important;
}

.tabbrowser-tab[selected="true"] {
  padding-left: 12px !important;
  padding-right: 12px !important;
}

This is only half of a solution. I tried this on my laptop (IBM X61t with Win10), but it makes the active tab shorter (less text visible) and any shadowed tab (unclicked mouse over) still has the wrong shape.

Maybe this:

.tabbrowser-tab { overflow: unset !important; }

Can confirm this works
