Now I'm a big Firefox fan. I like it so much. But there are some caveats bugging me over a long period of time. And some minor bugs sums up to some annoyances.
First of all, I have problems with the "AwesomeBar" when my screensaver or screenlock jumps in, and if I restart my computer from standby in Ubuntu (different version). It disappears. It won't work at all. I have to open the preferences dialog and open the tab for the bar settings. Then it will work as usual. This is so annoying. The bug is known for many month now on launchpad, and nothing has happened. I know this only happens under GNU/Linux. But that's what I'm using. And it doesn't help if everyone blames the other. There has to be a fix. Chrome works, so it should be possible.
Speed is the next problem. All this benchmarks and stuff isn't much about real usage. Firefox is significantly slower than Chrome on Ubuntu, no matter how you put it. No extensions vs. Chrome with extensions and it's faster. Yes, even the Flash-plugin, although the same, works faster. I can feel it, I can see it. Whenever Javascript is involved, it feels faster. The time I have to wait when starting the browser is also way faster with Chrome.
Resources used by the browser are also a topic. Not so much important, but after 5-6 hours of running Firefox, my Computer is getting slow. I have to quit and restart it (which can take up 18 seconds for Ubuntu to finish the task, so there is a lot of garbage collection going on). I never had this with Chrome.
On Chrome not everything is gold. I still don't want to have Apple named in my user-agent. So you can start Chrome with the non-evil User-agent with
