Hello,
Since an 3.5 update on firefox , the bitfender anti-phishing toolbar 2.0 is blocked.
"Not compatible with Firefox 3.5.7"
It is grey in list of extensions :
- Uninstall button is grey and not active
- no update available (and have not seen anything relevant in bitdefender base)
- Options button is grey and not active
What could I do ? 
My conf : Vista premium - Asus 32 bits - Firefox 3.57 - Bitdefendef Internet Security 2009 - Antiphishing Toolbar 2.0
Thanks for any valuable help
