Devs: STOP. CHANGING. THE. UI!
I don't know if it's a need to mark your territory, or some marketing major blathering about "holistic new user experience paradigms"--and I put up with the stupid move to tabs on top (because apparently some dev felt that what Firefox users really wanted was Chrome!)--but this is a hideous, steaming turd.
'Oh no, showing the 'close tab' icon and clearly delineating between tabs interrupts the synergistic flow of the UI! Let's make the tabs one disgusting, unreadable blur from left to right! Also, let's make them take up more real estate on the screen, because people have higher resolution screens now--we can totally dominate the upper quarter! Oh, and force the change to the new layout, don't give people an option to revert--and don't warn them, either! EVERYONE MUST SEE OUR MAJESTIC, PERFECT, UNASSAILABLE VISION! Surely that won't confuse TF out of a bunch of grandparents whose hapless children/grandchildren will have to completely re-explain, multiple times, how to get to Facebook!'
Rolled back to 88.01, went through the "new profile" crap you put in to discourage rollback/cover for poor programming, and disabled automatic updates. Barring a major, earth-shattering security vuln, I'm done updating. And when that time comes, I'll find another browser.
Posting here because they've stopped soliciting feedback--probably because they know they've unleashed a sloppy splattered dook onto the world and they're tired of being screamed at.
