Firefox 15 is really slow

I use both Firefox and Chrome on my Linux laptop.  Some websites are so poorly written, that even on Chrome they run really slow.  That is where the NoScript Add-On for Firefox comes in handy.  I use Firefox for most webpages, since NoScript blocks tons of crap.  I go to Chrome for watching Flash video or when I want a more responsive interface.

I noticed something when I upgraded to Firefox 15, however.  The entire browser started running really slow.  There is a significant lag between when I tell it to perform an action and when the action actually gets performed.  As an example, opening a new tab takes about 3/4 of a second now.  Page up/Page down can take up to a second.  Switching between tabs seems to take over a second.  I did a quick search and there is a support ticket that seems to match my issue.  The Mozilla people seem to think it is operating system related.  They said check things like Windows Firewall and see what anti-virus programs are running.  Really?  That sounds similar to "did you turn it off and back on again".  I know its not the operating system since Chrome didn't suffer a performance problem when Firefox upgraded.  Firefox has been my favorite browser for years.  What is going on with Firefox these days?
