In the case of microb I don't have an answer for you. As much as I prefer microb I have had trouble with a few sites also. (php? and doubleclick.com redirects.)

I tried Opera on the site sylo posted and it rendered better.

As a self defense strategy I would recommend installing a few different browsers, ie. Opera and Midori for instance. Not the ideal solution but use the tool that works
Take care.
