Rated 5 out of 5 stars
Yes, having Adblock installed does affect your browser start up time. With Adblock installed, start up time is 30 to 40 seconds, without Adblock 5 to 10 seconds, huge difference! But, the pro's for me out weigh the con's. But, is there another add on out there that does as good a job as Adblock??? (Please reply)This review is for a previous version of the add-on (1.1.3).
