Hrqls: Opera is paid browser (if you don´t like advertising banner) and firefox is freeware. I like and use them both.
Did you try thunderbird - email client?

My questions is: what application are you using for your work (have installed)? I mean basic needed for everyone (compress formats, burning software, browser, audio, video, antispyware, antivirus, firewall, image tools...etc)

It would be interesting to know what is popular and why.
