|Add-ons are generally very small in size.. especially in browsers. In my history of working with computers, I have never seen an add-on slow a computer down. What I think the problem more here is that one of the add-ons/toolbars that you have might be a trojan or a virus of some kind. |
What I would recommend is going to download.com and downloading a program called Spybot - Search and Destroy. It has rules and functions in it that search for problems and things just like this.
Please come back and let me know what it found. :)
