Firefox has started refreshing pages randomly. Like, everytime I hit the "back" button, it goes back to the previous page and then refreshes the page. And if I have multiple tabs open, when I switch tabs it stops and refreshes the tab I just switched to.
And some other times if I open a link in a new tab, the new tab will not load until I switch to a different tab. It will load in the background, and then refresh when I switch to it.
It's becoming annoying.
