A site is laggy when i use firefox what is the problem?

[Watervav]

The site is http://www.memecenter.com it recently updated the layout and a lot of features and ever since that happened if i use firefox the site is very laggy but if i use Internet Explorer (10) it goes swimmingly so the problem must be with firefox and im wondering what could cause the laggy when using firefox but not internet Explorer (10)?

Use Google Chrome is fast and it has more features sry for bad english and google chrome loads pages without any lag or anything else

Just use Google Chrome!
It's way faster than these two together and It's "lighter" in terms of Toolbars and stuff

I tried the site on Firefox v. 24 & it worked well. Then updated to v.25 & it still worked.
I would suggest updating Flash Player (Like Chrome, I.E. 10 has a built in Flash Player)
See if that works..

Also check your FF add-ons & extensions & disable if necessary..
