New buttons under LINKS sidebar

Noticed the FF and NS8 buttons under sidebar? I have tried NS8
recently but moved back to FF because I think FF deserves to be kept. NS8 is a nice attempt by AOL but it needs slimming. During a week or so of testing it crashed few times, it's a bit heavy weight comparing to FF and it's not that stable. I think after all AOL has other intentions for NS8 other than just providing an alternative browser.
