Did you try to disable the browsing history (Browser-Chronik)?

It's only internal by changing all addon updates to manually and by 
stopping other fancy things also. So it will be more complicated with 
newer fx version lacking ui support for switching those things.

I hope that your mozilla plugin directory is empty or plugin 
functionality is disabled - especially when upgrading from previous 
mozilla versions.

In the end I can only recommend to use seamonkey 2.28b5 (Dave's build). 
It has some problems with integrated audio-video support (fx has the 
same btw.). With latest mplayer + npmp-plugin it's definitely more 
reliable. Latest lightning 3.3.8 addon and couple of other addons seem 
to run almost without problems. I will report about results of long term 
https-ew usage soon.
