My one complaint is...doesn't *dark gray* usually mean something like "inactive"? I'm having trouble figuring out which tab I'm in when I only have 2 or 3 open because I keep thinking the *lighter* colored tab is the active one, not the *darker* one.
Ok, just figured out why I'm so discombobulated.

This is a disaster on my 2015 MacBook Pro. Anyone know how I can revert to an earlier version?

Yes, this change is absurd, IMO. Whoever decided on it should be fired immediately and banned from anything to do with computers or design.

Guys if you don't like Safari don't use it. Apple is too controlling. Things are beautiful on the other side, using FireFox ('http://www.firefox.com') and Brave ('http://www.brave.com') (Chrome without Google surveillance code) both of which are open source which is so much better for you on the privacy side and they let you do much more than Safari with extensions. Most problems I have with websites are Safari and its webkit engine anyway.

If you are looking for webkit engine and something that gives the same cool and quite performance of Safari, there is a new browser in beta called Orion ('https://browser.kagi.com') , its webkit based, get updates for older MacOS versions unlike Safari, and allows use of Firefox and Chrome extensions! Signup and you will receive an invitation link in some days.



Why what happened?



FOSS FTW!





I have been bitten before.

There are options in the browsers under bookmarks where you can book mark ALL opened tabs in each Window. You can save a copy. There is also an export option under File to user with other browsers too.
I like Safari, I hate this update.

Have been using Safari for a while and it has replaced Chrome in daily browsing. Sometimes, also when developing, as I find errors faster, as Chrome is more error forgiving which tends to bite you in the end.
Safari is generally faster and no noice from the fans.

Ugh, maybe I'll get used to it but right now I'm finding this "chameleon" toolbar very awful to look at -- it's different on every site I visit and calls so much attention to itself. If you switch tabs a lot, it's very distracting. Maybe someone will write a plugin that stabilizes its appearance. Not a fan!
You could always... turn it off
