Since upgrading to 5.0, many websites tell me my browser is not up to date (for example, if I try to sign up for Google +, it says my browser needs to be upgraded...same with some pages on FaceBook). This is keeping me from using some websites and quite annoying.

Not sure if it's related, but ever since I did upgrade, if I click on options on one of my add-ons, nothing happens except it renders the browser frozen and I can't click on anything without having to force close it and restart the browser.

In case you did not get why Ed gave you that link, you appear to be posting with a Firefox 3.5.5 useragent . It was not until Firefox 4.0 and newer that Mozilla made it so extensions could not tack stuff on end and potentially make the UA get stuck at the version one had when a the extension that affected it was installed.

Your useragent. Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 FBSMTWB
