PrivateTab button with Firefox UI Fix installed have wrong shape

[Aleksandra0056]

When I have installed “Firefox UI Fix” (https://github.com/black7375/Firefox-UI-Fix), then added “Open a new private tab” button right next to right “Open a new tab” button, then the “Open a new private tab” button have wrong shape (The shape of “Open a new private tab” button is wrong but the shape of “Open a new tab” button is right). In short “Firefox UI Fix” is not supported in “Firefox scripts”.

I will attach two screenshots for better understanding:

Open a new tab button have right shape.

Open a new private tab button have wrong shape.

If it is this issue with “Firefox UI Fix” and not the “Firefox scripts”, then I should file a bug in “Firefox UI Fix” bug tracker instead (But I think that I am in the right place, so I reported it here).

IMO this is feature request for “Firefox UI Fix” - CSS is injected on #tabs-newtab-button and "only" Google duplicate ID in (x)html5.

Fine, I will soon close this as not planned, and post feature request for Firefox UI Fix.
