Minor Security Flaw in Mozilla

MozillaZine reports that there is a minor security flaw in all current releases of Mozilla. Basically it allows a website that uses the onUnload Javascript handler to find out what website you are going to. Unfortunately, this issue has been known for awhile, but hasn't been fixed yet.

There is a simple workaround, though. Create a file called user.js (if it doesn't already exist) in the same directory as your prefs.js file. Add this line to it:

user_pref("capability.policy.default.Window.onunload", "noAccess");

As far as security flaws go, this is a rather minor one. I suppose it's only really problem if you visit a porn website right after your church website or something :) Despite the fact that it is minor, I'm very disappointed that it's been known for months, but hasn't been fixed yet.
