0Annoying firefox extensions that can’t be removed

I have vari­ous annoy­ing “exten­sions” lis­ted in my fire­fox install that can­’t be removed through the nor­mal exten­sions tab. Here’s how to get rid of them…

1. PC Sync 2 Synchronisation
run reged­it and delete the key bkmrksync@nokia.com in HKEY_LOCAL_MACHINESOFTWAREMozillaFirefoxExtensions

2. Mul­tiple Java versions

Run fire­fox as admin­is­trat­or and remove thru nor­mal panel
