I’m really beginning to appreciate the lockin caused by browser plugins. It’s just simply easier to keep going back to my Firefox browser from Safari or Chrome to get some plugin love (time savings). Predominantly, this is a hassle-of-change lockin. Still it’s real.
I haven’t done much research on Safari plugins, I’m sure there are some good ones out there and I found a few here at Pimp My Safari. Chrome is fast and if it had the plugins Firefox had I might be tempted to set it to my default browser. My top 3 plugins are Firebug by Parakey Inc, MeasureIt by Kevin Freitas and SeoQuake by Aramis, Pelmen and Lelik.
