I run windows XP on PC. A windows explorer style window popped up, urging me to update to Firefox 21. The window included a "more info" link and a "remind me later" and "install" button. I have never seen this style of notification before so clicked nothing and dismissed the window. Is this a legitimate firefox notification? If not, what have I been invaded by, and how do I proceed?

hello, it's hard to judge what was going on by description only - in case it does happen again, please try to create a screenshot of the dialog in question and attach it to a reply in the forum here...

in any case, firefox 21 has been released last week and you should indeed update to the latest version. just go to firefox > help > about firefox in order to search for & apply the update.

Update Firefox to the latest release
