Sorry to take so long to answer. It's been really hard to access the site.What error? please explain in more detail.
Actually the last time the issue happened to me was probably 2 or 3 years ago. Version 3.5 has been a jewel so far. Also they found a potential Java exploit last Monday and gave us a new fixed version on Friday. I'm running Version 3.5.1 now.
When they come up with something like "AdBlock" and "NoScript" for Chrome or Opera I might consider trying them. Til then I'll stick with Firefox.
