Fixing firefox after upgrade

Firefox recently upgraded to 3.6.15 and in the process appeared to mangle all of my add-ons – really very frustrating when they make a significant difference to how I interact with firefox. Fortunately I found that there were a couple of useful fixes available; firstly to clear out the extensions cache and ini files as described by David Moore IT service blog in the article How to Fix Firefox Break Down Add-ons. The second thing was to do a bit of updating manually – some of the add-ons have updated that you can get from the mozdev.org site that haven’t yet made it onto the firefox repository.
