Have you tried Snoopium to see what fonts are being searched for ?

This beta 4 has many improvements on beta 3 but I am finding more crashes than beta 3.

For example, a page kept trying to reload the same few images. I don't know if that was a javascript or what.

Anyway, it's definitely more usable, a shame the stability is slightly less. I am sure beta 5 will be even better :)
