Safari Web Content quit unexpectedly

hold shift key and open safari>> clear all history.

go to library delete safari folder

under the library>> preferences >> remove all safri plist.

reboot your mac.

( if you want you can save the book marks and top sites under the safari folder. drag them at your desktop before deleting)

Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items. Quit/reopen Safari and test. You can also try try Safari/Clear History…. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Caches/com.apple.Safari/Cache.db and move it to the trash.

Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.

Hello,

I had been having the same problem and I followed most of your recommendations and so far so good in terms of no longer having random safari webkit quits. However, in the last month I started to have the "web content quit" specifically with yahoo. I have an email with yahoo and when I'm in my mail, on the home page or reading an article from the home page I repeatedly get that error message and it reboots the page or article or kicks me out of an email I'm reading and sends me back to the inbox. I've tried those help steps you listed again and I cannot get to the Show Library Folder to get to the caches. (I have a Macbook Pro 2010) My Finder doesn't seem to show it. I've used the Go drop down and don't see it nor can I seem to find it in view->show view options either, there is no checkbox. I haven't contacted Yahoo support yet as my issues were at first in general now only with Yahoo. If you have any suggestions or advice I'd greatly appreciate it.

Thank you,

Kevin

I had the same issue and improved it by blocking Adobe Flash Player for those websites: yahoo.com att.net ebay.com

Safari Menu -> Preferences

Plug-in Settings

Under Adobe Flash Player, choose Block (or at least Ask) for each website

If you don't use Flash player, I would recommend disabling the plug-in altogether.
