to the one mentioning his firefox is blocked/erased and he/she now has to use IE:
you did something wrong!
maybe erased one thing too much?
- if you don´t have a "restore" option,install firefox again.
i know it is convenient to have your passwords eg automatically stored and inserted when you visit certain pages, but i would never do so.
- if you have set a date for system recovery (recommended!), just recover your system.
it´s really not rocket science ;)

i am using the tools as advised by OP, and it does work.

for all those paranoid about being followed by glp:
it is only 4 sites following when you´re on here.
that is - from my experience - less than when you read your online newspaper.
to those afraid about who is following them:
it is google+, facebook, twitter and Quantcast

just the usual suspects. no doom here ;)
