I'm running the latest version of firefox 17.0.1 on ubuntu 12.10 on a Acer Aspire One 722 Netbook. It has an amd dual core C60 processor and 2GB RAM.

As you can see, firefox is absolutely killing my system, it responds really slowly and opening tabs is a royal pain. I have on an average 4-5 open tabs at a given time. Is there something that I can do to make my browsing experience more zippy?

Additionally I run the following addons

1. Firebug
2. HTTPS Everywhere
3. Ad block plus
