Well I experienced some inconsistency with the html navigation too (not linked to the issue mentioned before): tapping on links does not always work properly.

I noticed that especially when navigating certain sites (gmail, in all fashions, and ITT Forums, in mobile version): the pages won't open (it says "connecting" in the bottom bar and takes for ever). In the same conditions other web sites (Nytimes, repubblica.it), heavy sites with images and other stuff, are downloaded pretty fast.

Maybe it depends on the server? But for Gmail as well?
