Firefox hangs with 100% when reloading a page on Mac Lion
I am using Firefox 16.0.1 on a Mac running Lion 10.7.4 and Java 7 update 09. When reloading any web page that uses Java, a new Firefox task starts which uses 100% of the cpu and hangs Firefox. By doing a 'force quit' on that task, Firefox successfully reloads the page and the cpu and Firefox return to normal.
I have disabled add add-ons, I have re-downloaded and installed both Firefox and Java and nothing makes any difference. I have even gone back to Firefox 13.0 but it had the same problemI would welcome some help please.
Additional System Details
Every time Firefox opened
This started when...
new version of Java was installed (I think)
- Shockwave Flash 11.4 r402
- Displays Java applet content, or a placeholder if Java is not installed.
- User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:16.0) Gecko/20100101 Firefox/16.0
