FireFox & Thunderbird "not responding" issue

Hello,



Hello,   I have recently run to a problem with a streaming capture program which was causing a BSOD 0xC2. Finally determined that it was related to the rrnetcap.sys from Audials. Anyway, used Revo UNinstaller to remove all traces, I think. Have had no issues with booting/startup in Windows 7 SP1. I then began to realize issues with both FF & TB afterward. So, being frustrated saved my profiles and uninstalled with Revo Uninstaller as well. Finally things still working correctly after 4 times finally uninstalling and reinstalling, decided to remove anything which remotely looks like a plug in. Adobe, Flash, Java, etc. Reuninstalled FF & TB completely, and even after removing any traces of Mozilla in registry, still having a problem with nothing but a clean install, default profile, nothing else added FF alone still have a problem with trying to open Options. If I try using "about:preferences" I get the same response. I realized this in TB as well and that's why I figured this to be a common problem between the 2 applications. I have performed CHKDSK with recovery no bad sectors, performed SFC /scannow - all is without error. Really cannot figure this out, and see nothing discussed as similar. Have tried other things noted in forum, but perhaps I have overlooked something. Appreciate any assistance anyone may have.

This question has been posted to the Mozilla Forum and have received the "pat" answer. I have followed the recommended clean install, all with totally default settings after removing all traces. Additionally, have removed whatever I can recall as "plug-ins" including Java, Flash, Real player, etc. all. This is a strange problem seems to be solely related to the Mozilla applications. It first caught my attention when attempting to "send to" an email, and also realized attachments did not work either. Honestly, I am guessing I am going to have to totally reinstall Windows if no one has any ideas.

Thanks

Brian
