For my general browsing, I use MicroB.
I installed AdBlock plus for it, so the flash ads don't bother me anymore.
Despite everyone from the N800 / N810 era seems not to like it, I think it is a fairly usable browser.

When I want something like searching a page from my desktop, or checking for something in my desktop tabs, I use Firefox.
It is fast, but you have to wait a little longer, and it renders the entire page. Then, it is more responsive than MicroB.
The nightly Fennec builds are even better.

Unfortunately, Tear and Midori are out of the question currently.
