Safari keeps crashing in OS X 10.4.4 and 10.4.5 but is stable in 10.4.3
I've been putting off upgrading from 10.4.3 because of this problem but have decided to take the plunge. Safari crashes at random times and there doesn't seem to be a rhyme or reason. Sometimes it's stable for hours. Sometimes it crashes after minutes. It can crash while I'm opening a new web site, just reading a web site, in the middle of a Youtube video, etc.
I've already done the following:
Deleted Safari cache
Deleted History and Bookmarks and Cookies
Deleted the contents of ~/Library/Safari folder
Deleted the contents of ~/Library/PubSub
Deleted the contents of ~/Library/Cookies
Deleted the contents of ~/Library/Internet Plug-Ins
Deleted the contents of ~/Library/Caches/com.apple.safari*
Deleted ~/Library/Preferences/com.apple.safari*
Deleted ~/Library/Preferences/com.apple.webkit*
Disabled all extensions
Rebooted in safe mode to clear other caches
I've also tested Safari with a newly created User and it *seems* to be stable, but it's also possible that I didn't test it long enough.
Is there anything else I can do to fix/troubleshoot this?
