Short and sweet, what are you using and why? I was pretty happy with Firefox 1.5 really. It's not noticably as fast as IE but it does the job. Tabbed browsing and some security niggling feelings were why I used it over IE but I'm not a browser zealot. So now we've got something unprecidented, a couple of major revisions to the browsers we most likely use. So what do you used and why.
For me, when FF 2.0 came out I foolishly upgraded off the bat, having seen how long it was in beta I thought it'd be fine. It's not fine. It randomly doesn't start up and when it does this, even killing the dead exes from the task manager doesn't always coax it to start up. It locks up. It uses 100% CPU time, particularly on flash and PDFs. There's stuff I do like. Well, I like the form spell checker. To be honest, that's probably about it but otherwise the stability issues make it more or less useless.
So, IE7 then? The tabs are nice. I like the little blank one you click on. I like opening stuff in a new tab inserts it next to the parent tab. I love the speed of it and it's been rock solid for me. There's only two things I don't like, one is that when I do the toolbar folder bookmarks folders type thing, there's a bit of a fade/delay when hitting them which isn't as quick as FF. I'm also not happy about the fact that when I copy text from HTML tags in a form, IE7 randomly decides what character to start copying from and wont let me begin with < exactly, requirign me to edit every paste by hand. What's that about? Also, I've decided I quite like an in-form spellcheck as per FF although I'd like it with an English dictionary as well.
My options are to try get my bookmarks from FF into IE7 and then bin FF so I stop firing up the damn thing. Or to somehow downgrade to FF 1.5. I think on balance I'd prefer to use IE7 for the speed and because, I assume, FF 1.5 wont be supported forver. I bet I can find a little add-on to in-form spell checking with IE7 also and it's definately useful that those pesky ActiveX controls actually just work in your regular browser rather than having to dig out IE just for those.
So anyway, what about you chaps?
