Firefox V3.5.10 vrs v3.6.6 in Software Posted July 11, 2010 Yeah, over the last few major updates to Firefox, I've noticed that it grew bigger and bigger in size. It also seems to lag a bit too, like when my custom Google background loads. I only have AdBlock Plus, Java Console, and Chromifox extensions, and the Chromifox theme. I'd suggest Google Chrome, but it has even more of a "plugin separation"... as in, each tab AND each plugin creates its own process, as well as the actual program. At least Firefox attempts to store my tabs if it crashes.
