I've been using Chrome on my Ubuntu machine. It seems a little faster than firefox, but I really can't live without Adblock and Noscript on Firefox.
There are at least two adblock systems for Chrome. I'm using it right now. I don't know about the Noscript, I've never used that before.
My impressions of Chrome are very good for speed, but I've had it lock up several times in the first week or two. I'm running it on my W7 64 bit machine, and on my XP Acer Aspire 10.1" machine. In both cases, the stuff most always come blazing onto the screen, but every now and then, something just won't work. I also am quite aware of every thing being monitored by Google, even watching the googleanalytics notification in the progress bar at the bottom. Especially whne a page won't load. I'm thinking that maybe the googleanalytics may be at fault for the crashing of the browser.
I'm thrilled that Xmarks is finally included. It is the primary reason I was staying with Foxmarks for so long.
