Lagging means that there is alot of memory is being used by Firefox so make sure you don't open enormous tabs and also watch your add-ons since there are some add-ons were reported to have problems with memory like memory lacking, etcetera.

Start your Computer in safe mode. Then start Firefox. If there is still a problem, try FF in save mode also.
