I've been using Firefox as my primary browser since 2005-2006ish. A site misbehaving because of it is a rare enough occurrence that offhand I can't remember any time that it has happened.
One issue I do come across occasionally, and I'm not sure if it's Firefox alone or the combination of add-ons I use in Firefox, is sites being overzealous with captchas. I find myself doing 3-5 captchas occasionally just to use a site.
