The only problem I have encountered that if you use the "back"-button twice, quickly one after another, the browser will hang with ~100% CPU. This is new to the latest version of Diablo.

And I tried the livejournal page you mentioned in your bug report, and it loads perfectly, no hangup and no extensive CPU load.

So the bug is not in microb!

I suggest, though, to get rid of any "addons" including adblocker. In my experience, they just do harm and make the browser slower.
