Sometimes this is simply because the site preemptively throws an error on detecting Firefox because they don't want to QA another browser with a smaller market share. Usually those sites work fine if you just change the user agent Firefox reports to look like Chrome (there are add-ons for that). Personally, I haven't had to resort to a non-Firefox browser or user agent spoof even once in well over a year now.
