Revision to previous comment Rated 5 out of 5 stars
I'm sorry to have been unable to look properly into settings, and the selected tab visual focus settings were there indeed, both GMF tabs v2 and Alt. tabs v1 definitely fits my needs. Although, it should be noted that sites with SSL encryption increase the URL text area slightly so there are height differences between SSL and non SSL sites. That's a slight visual quirk that would be great to be fixed.
Overall, great addon and congrats on your great work :)
Could you post a screenshot and an url where that text area glitch appears? I've tested some sites and did not see any height differences:
Btw, there are no changes on urlbar text in this extension, maybe another one causes the glitch?
