I'll see what Secunia PSI say on the subject. They've been telling me for sometime now that the last official 'Firefox' version was recognised as unstable, as is IE7. Adding if I wanted to go on using Firefox and IE7 there was nothing I could do about it.
They didn't mention the Beta version, so I supposed that too was unstable! (as most beta's quite often are?) So I tend to steer clear of beta's in the main. Unless it's a new free art or music package. Which I may be getting in as a beta tester, with an option to keep for free when the product goes commercial.
