I swear this update of Safari has to be the worst one ever!!!!
*** were they thinking by getting rid of favicons....when you look at a web-page with loads of tabs open on a 27" imac it's impossinle to differentiate which tab is which without pressing your nose against the screen.... who's bright idea at Apple's was that.... some hipster dude who thinks 'grey' looks cool? I can imagine the problem might be worse on a Retina laptop. Also the difference in grey variance between an active tab and the others is practicaly non-existent so, yet again, you have to squint to see which one is open.
If anything the speed issue seems to be getting worse.... first few tabs fine.... then it's like crawling through treacle.... I have 8GB ram, - this never happened with the older Safari version....
Also some other have mentioned scrolling seems to just stop working on some pages with huge bits of white space.... I can confirm the same for me.
Did all the beta testers just open one or 2 tabs and that's it?
I could have bought myself a new Ferrari with all that I've spent on Apple over the years and have to say the last 2 Safari updates have been truly terrible.
Steve Jobs would never have accepted this version.
