Yeah, as I mentioned in the quick review, LastPass seems to have some buggy issues, thought it still works overall. I am using the Dev channel too, though — I wonder if people have better experience with the Beta?

I have noticed not a single bit of slow down with extensions installed. Not even a tiny bit!

I originally went with Chrome, back in the day, because its load time was so much faster than Firefox. I could just start the browser and be on line in a second or two, even on a slow computer, whereas Firefox would take up to a minute or more (waited for 5 more than once) to load, and would often hit me with update screens beforehand, etc. I went back to Firefox with the advent of Firefox 3, as the load times had been streamlined a bit, and my workflow had become so online-based that I needed the extensions offered. — Lately, it has been annoying me though, and was getting slower and slower, it seemed. I had to leave the browser open and sleep-mode my computer to keep things fast. Now, I am almost 100% back to Chrome — I just need the extensions to improve a bit and Firefox will likely not see me until Firefox 4 is released…
