After Installing Bitdefender 2011 Firefox is very slow and worse when multiple tabs are open

Firefox performs very poorly after I installed Bitdefender 2011. There was no such problem with Bitdefender 2009. When multiple tabs are open, switching between them is not possible until tab contents are completed.

I found that disabling the bitdefender anti-phishing toolbar solves the problem. Which leads me to believe that when a page is loading, the toolbar checks to see if it's a phishing page which causes the delay.

As ninjafox says, the problem seems to be the BitDefender Anti-phishing Toolbar. Disabling this through Tools -> Add-ons and restarting Firefox seems to fix the problem for that session. However, the problem then reappears when the computer is restarted, presumably because BitDefender re-enables the toolbar.

Another way of disabling all add-ons when starting Firefox is to hold down Shift while clicking on the icon (Windows only I think - at least doesn't work on Ubuntu for me).
