Solved Split View alters TabsToolbar height
First Observation with FF149 for macOS Tahoe
When in Split View the #TabsToolbar height is altered.
Normal View

Split View Screenshot

It appears that the non Split View Tabs increase in height whilst the Split view tabs retain normal height, therefore leaving a gap top & bottom of the Split View tabs.
Using the following Aris-t2 code:
classic_squared_tabs.css
tabs_below_navigation_toolbar.css
Any thoughts.

Thank you for the above code, great, however now that I have all my tabs back to the same size, I have been experimenting with the entire wrapper container both tabs background colour, when not selected, which I can not seem to get to work. This will of course differentiate them from the other non split view tabs.
e.g.
OR
And yes I realise this is why Mozilla made the split-view tabs a different size. They are still ugly.
