Check Your History Settings

Remembering your browsing history can make Firefox slowly.So better it to remember history for less number of days to optimize Firefox more.Change this by going to Tools—->Options—->Privacy—->History. OR you can manually remove history by clicking Remove Recent history in that window.

Bonus tip : You can remove your browsing history,cookies,cache and all your browsing data just by pressing Ctrl+shift+Esc and choose the time period from where you wants to erase your history.And If you don’t want Firefox to remember your any browsing data for some time then select Start Private Browsing from tools menu or just by pressing ctrl+shift+P.
