In my observation, the 47 was a lightweight and stable version. Since it 
does not handle new features, new browser is needed.

5x starts chewing more memory when loading certain pages on both FreeBSD 
and Linux.

54-57 seem having a bug that can take Nx100% CPU when loading some pages 
(consume all cores).

Not used any 6x, but when upgrading to 7x, Firefox starts slower, and 8x 
starts even slower.

The latest Chrome starts slow as well. Not clear if this is related to 
new web features, Xorg, or browsers.
