Why does Safari hang in OS X Lion?

My Safari does exactly the same thing (MBP, bought around April 2010, recently upgraded to Lion). However, Chrome does none of these things. Sorry, Apple, but I will have to switch to Chrome for a while.

I am seeing Safari 5.1 hangs on multiple machines. The problem seems to occur only when there are multiple Safari Windows open, and most often when filling out a form. If I quit Safari and immediately restart and Safari "remembers" and reopens the previously hung window, the hang is cleared and I can complete the form successfully. My wife is more effected by this than I am, but then she often has several Safari windows open at the same time.

Speculating this problem may have its roots in Safari's infamouns memory leak, we have been able to reduce the frequency of these hangs by quiting and restarting Safari more frequently. I have used and like Safari from its very beginnings but this is becoming annoying. By-the-way I have tried other browsers such as Sunrise and LIghtening that are based on Apples Webkit and I have not encountered similar problems.

I have a similar problem.

My safari will freeze even I just boot the Lion OS.

Just to share: My apps hang or freeze when i'm on Energy Saver:"Higher Performance". So when I change to "Better Battery Life" it would not freeze anymore.

Please let me know if that really help as I am not quite sure this will help because It might caused by my faulty graphic card. Please share!!

I am having the same problems since I upgraded to Lion (10.7.1). In Snow Leopard Safari would ocassionally hang. Now it hangs A LOT. I don't like force quitting apps, so I usually exercise patience and give it time to get out of the mud. But there's a limit to everything. Firefox is working well, but I would rather continue using Safari, as long as it works properly.

I'm not sure what else is going on on your system, but in several hours of web surfing a day I never see this behavior on either my 12 GB MacPro or my 4 GB MBP 2009 era MBP.

I wonder if there's a system extension somehow causing this or if there's something else networking-related going on.

(It certainly could be Safari, but I don't understand why I don't see it, though I do not use tabbed browsing.)

Last month, purchaced a new MacBook Pro, i5 (comes installed with Lion) - Safari hangs and so does mail. Not seeing other apps unless mail and/or safari is also running. Haver performed all updates...problem persistes.

With as long as I've been with Mac -- (since the mid 90s) this is the worse experience I've had with upgrading my MacBook Pro. Safari craps out... MS Office 2011 ... and when you look at the Task Manager it says not only is the app not responding but it's the Finder not responding and you're forced to do a hard crash.

I've had this for a week and am regretting that I upgraded to Lion. Note: I had less problems with Lion prior to upgrading to 10.7.1 -- so I've no idea what you're talking about.

Furthermore, I agree with the others who are also jammed up. Stating that you're not experiencing the problems doesn't mean that there isn't one.

Severely disappointed and not looking forward to wiping my machine to re-install Snow Leopard. Shame on Apple.

Oh and I just attempted to Reset Safari and guess what happened?

IT HUNG!!! UN-BELIEVABLE!!

There's something seriously wrong with your system - either hardware or some piece of software you've installed that doesn't like Lion.

I had the same issue with web pages hanging. I'm running net barrier for secondary security. I turned off banner filtering and the issue seems to have been resolved. Not to say that everyone is running net barrier but if you have any non apple security or internet security apps running you may want to check the config for any sort of internet site content type filters and turn them off.

I don't run Lion, but the latest version of Snow Leopard and I have this problem too. It began when I updated to Safari 5.1. I don't have any third party extensions installed and I've done all the lame stuff recommended on the various sites like reset safari and downgrade Flash to 10.1, Nothing makes a difference. Apple needs to recognize they have a problem with this latest version and fix it. Meanwhile I'm using Firefox, which runs perfectly.

Sorry, but what does it mean to "reset" Safari? (I'm having the same problem -- the everlasting beach ball that prevents me from quitting Safari or even getting to any other app. I have to shut down via the on/off button.)

Click on "Safari" menu and you'll see "Reset Safari". What that does is clear the cache, all cookies, history, etc. It can help when Safari gets sluggish from time to time and with spinning beach balls. The problem with safari hanging up on some pages regularly, such as Yahoo Mail, is a problem that was introduced with the latest version.

Thank you. I'll give that a whirl. I see that the latest Safari update is supposed to "address issues that lead to hanging" or words to that effect.

My 15" MacBook Pro April 2010, has been doing the same thing, called Apple support about 5 times, deleted cache, you name it. Re-installed fresh Lion, about 3 times, did hardware test with Apple support, all ok. Finally gave up on Safari, and went to Firefox about a week ago. Not a problem since.
