This aspect of Safari 5.1 is really lame!

I'm now using FireFox after a ridiculously long delay last evening and Safari Web Content slowly but surely grabbing more than a gig of my 4GB of RAM.

I have to get work done afterall.

I had Safari crash when having 10+ tabs open in previous versions, but now it pops up with the "Web pages are not responding.." window several times a day. Really annoying.

I have 4 plug-ins running, doubt those are the problem as I've had them for quite a while and didn't experience Safari being this crappy before.

Quite disappointed in Apple bringing out this bad software. Should probably try Chrome.

I made a mistake earlier : I don't have any error window.

I think "Safari Web Content" is crashing because of USB, but it seems to have no real connection to the problem on this thread.

Sorry. :-(

Same problem here. S*fari has been getting less and less useful and is now almost completely worthless! Obviously Apple's SE's are not reading my bug reports or suggestions! I don't see why they refuse to code a browser to allow THE USER to decide which page(s) get access to CPU and Memory! I may need 100 pages and tabs open, but I do NOT need Flash and animated gifs running on 95 of them while I'm trying to work with the top five. I guess people at Apple don't actually use web browsers except for maybe one page at a time. Yeah, the "geniuses" told me to only have one page and one tab open at a time!! :-/

I'm still having this problem. I used to love Safari but now it's a joke. I finally caved in and loaded up Firefox for the first time in ages (I think it's still version 3.X) and it was blazingly fast compared with Safari. I'm going to try to do more and more of my web usage via FF.

Yes, I typically have many many Safari tabs open, but that shouldn't be a problem. In this day and age it is insulting to expect a user to have open just 5 tabs.

When I'm really bored, I will still go to Activity Monitor and watch Web Content slowly take more and more memory.

I switched to Chrome. It's fast as ****. No reason to turn back to Safari.

One month and seven days after 5.1 was released.....crickets

This problem is well documented and covered.

However there is NO SOLUTION yet.

I need Safari for Applescript. Firefox is worthless with applescript...

Apple, PLEASE fix this!

OS X Lion is: =(

For me the extension "Facebook Photo Zoom" will cause Safari to spin the beachball like mad upon startup.

LAME? i think you're being too kind. it boarders on idiocy. of course, a lot of iOS5 does...

Well, yesterday's update at least seems to have resulted in Safari Web Content giving back RAM when it's done. I just had it lose 800MB after I closed a bunch of tabs/windows.

Early times, but 5.1.1 seems to be better.

PS: If you have been using 5.0.x I highly suggest resetting Safari and restarting it. I had some weird rendering errors before doing this.

OK, so instead of the "Webpages are not responding" dialog of doom which forces you to reload everything, 5.1.1 simply reloads everything as though I wouldn't notice.

FAIL!

Oh c'mon Apple. At least allow me to file your bugs as bugs instead of auto-rebooting. Next Microsoft will claim Windows is bug free by auto-rebooting instead of displaying a blue screen.

Yeah i noticed that... It's like brushing the dirt under the rug.. How very Microsoft!

Admitedly i only get this on pages with super long content but Chrome and FF seem to manage..

FAIL! +1
