    I've never been able to use Firefox as my primary browser, it's actual performance has always been pretty terrible on OS X. Since 4.0 I actually have to launch FF, quit it and relaunch for it to be responsive or let it 'warm-up' for a few minutes. I've always felt like if FF on the Mac is a low priority for the Mozilla group. I hope 'Telemetry' gets Mozilla to care more about UI performance.

    On the other hand Chrome has always performed great on OS X, since beta, and It's my primary browser.

    Another pet-peeve for FF: it's not possible to run 2 versions of it at the same time and checking/relaunching for plugins at startup.
     
  3. @marioestrada: As of Firefox 4, addons are no longer updated at startup, interrupting the flow. Instead they update silently whilst Firefox is running.

    It is also possible to run two versions at the same time, you need to add -no-remote to the command line - and if you want them to use different profiles, you can add -P "profilename", with a different profile for each.

    If you are having slow startup issues, I would also recommend trying a new profile, since broken profiles (and a build-up of badly performing addons) can reduce it drastically. To run Firefox with a clean profile, see:

  4. I don't understand how people still care about memory usage. You can buy 8GB of RAM for less than $80 or 16GB of RAM for less than $150. I'm running only 6GB and I rarely see more than 2GB actually being used. :s
     
  5. Yes, let's throw money at the problem instead of coding efficiently or creating a more on-demand, consistent experience. What exactly do you want Firefox to be? Vista RTM?
     
  6. Because very simply with modern CPUs access to uncached RAM is very slow!
    That's what SMT is about, run 2 threads in same core to do something on 100 cycle memory stalls.

    Before FF3, I found it bloated and slow (even with 4GiB), but thanks to efforts at improving memory usage, it's felt fast & snappy on my box since and it's even OK on a 1GiB Athlon 2000+ machine that's 8 years old.

    I'm running both the Aurora and Nightly versions of Firefox and the browser is indeed much faster on startup and while browsing the Net so much so that sometimes I feel that it is actually faster than my Chrome 13 Beta.
