Sometime Firefox crashes due to overload and thus there is a limitation on how many tabs that you can open in a single windows of Firefox.

One of the beautiful feature of Firefox is that, if your Firefox is crashed then it will automatically restore all the tabs when you reopen Firefox but sad news to all there is a limit on the numbers of tabs that can be opened if your Firefox is crashed. If it exceed the limits then the Firefox will not open the recently crashed tabs.
