I was hoping for favicon bookmark support, that keeps me from using safari now. Oh and 1 search bar like chrome's would be nice...

After the update I have up to a staggering 97% free CPU! Wow. Was averaging 55%, now 85% and above.

Sorry, Safari it's too late to go back to you. You were too slow and used more memory then other browsers.

Safari became unusable in Lion. Dumped it without a second thought. Most of apple's latest releases have been less than pleasing.

Thank you. Just downloaded and rebooted. It looks much snappier and has much less memory usage.

If you want Chrome to continue to improve, you would try Safari when it improves. :D
 
Can't be any worse than 5.1 unless it just didn't launch at all...and that could arguably still be considered an improvement!

So far so good.

I've used the Safari 5.1 fiasco to familiarize myself with the other browsers out there. I'm using Firefox 6 as my default browser now. I do miss Safari's autofill. The drop down menu of choices is a bit slower to use most of the time.

Installing Chrome allowed me to delete the Flash plug-in from my system, but I do not want Google tracking everything I do on the web so I only use Chrome when I absolutely need Flash support and fortunately that's not very often.
 
For the record, the Windows version of Safari still doesn't preserve printer margin settings. That's a long, long, long running bug.

Also, very basic printer settings (like header and footer type and location) are missing entirely.

Said another way, Safari for Windows can't print too well.
 
Whats the build number of this patch? I'm currently running 11C73 and honestly cannot remember if its the new patch or the latest beta version :p
 
Somewhat better but still sucks. After a day or so of use pages are spontaneously reloading again. Feck!
 
Safari 5.1 and 5.1.1 have been a train wreck for me so far. Everyone I know, as well as myself, experience increased beach balling, especially on wake from sleep, and random graphical glitches. Especially on Snow Leopard. Was hoping 5.1.1 would fix it, but alas, that hasn't been the case.
 
Pretty much. I think it is somewhat better but still needs a lot of work.

I have a feeling that they changed the caching and memory management for the desktop version of Safari to use whatever new one they have been working on for Safari in iOS5. Would explain why it is performing so horrible with 'efficiencies' that don't make sense in a desktop environment where RAM is not so limited.

For the love of the Jobs Apple, please don't let this happen to Safari.
 
Downgrade?

Better but not great. Any easy way to downgrade? Launches VDCassistant too > :confused:
