Rated 3 out of 5 stars

There's no doubt that this add-on improves performance but it has caused me a headache recently. While using only the moderate 'Optimised' setting, my IP address was banned by a web site which I need to visit regularly. To other Fasterfox users: if you ever find that a web server on a small site suddenly becomes 'unavailable' after you've hit it a few times, Fasterfox may very well be the issue.

This review is for a previous version of the add-on (3.8.2Lite). 

I have never had any problems with any web sights using even the highest of settings.
