How can I download FF 6? FF 7.0.1.4288 (the version I am using) is not compatible with Norton 360. I need to return to FF 6.

FF 7.0.1.4288 intermittently uses 97-100% of CPU capacity for a few seconds, alternating with a few seconds of normal idle usage; this can continue for long periods. During these periods the computer responds very slowly. I can terminate it (temporarily) by rebooting.

FF 7 occasionally uses 97-100% of capacity continuously for several minutes; my impression is that it would continue indefinitely if I did not reboot. When I try to reboot in this condition, FF does not respond, I have to click End Now, in which case previous sessions are not saved.

Norton believes this is due to an interaction between FF 7 and Norton 360. They say that 7.0.1.4288 is a beta version. Norton tells me that 360 should become compatible with FF 7 in a month or two. In the mean time I need to reinstall FF 6. I cannot see how to do this on your website.

Please help.

Firefox 7.0.1 is an update to Firefox 7.0 and there was no beta of Firefox 7.0.1.

You may need to update Norton. A patch for their toolbar to make it compatible with Firefox 7 was released on the same day that Firefox 7 was released. You may need to run Norton's "Live Update" several times to get all that is needed.

Does not relate to your question, but...

You have multiple old Java Console extensions that Java did not clean-up during updates. You need Java Console only if you do Java programming/development or debug Java applets on web pages. You can see them in Add-ons > Extensions, but you can not remove them from there. Removing them will not affect the functioning of Java on websites. You can manually remove them, if you do not do Java development work to avoid future, possible problems/conflicts:

Your old Java Console extensions:

  • Java Console 6.0.22 {CAFEEFAC-0016-0000-0022-ABCDEFFEDCBA}
  • Java Console 6.0.23 {CAFEEFAC-0016-0000-0023-ABCDEFFEDCBA}
  • Java Console 6.0.24 {CAFEEFAC-0016-0000-0024-ABCDEFFEDCBA}
  • Java Console 6.0.26 {CAFEEFAC-0016-0000-0026-ABCDEFFEDCBA}

I followed the instructions I above. I downloaded three Norton updates, none of which mentioned FF, and then got a message that there were no more available. So I appear to have all updates, presumably including the FF 7 patch. So it appears that my problem is occurring despite the patch.
