Hope I fixed my mouse’s right click this time for my FF browser w/my Dell laptop

I’m fixing my right click problem with my dell laptop right now. Many times, I’ve uninstalled my FF browser to see if right click will be fixed. But it’s the same. Until I uninstalled everything I stored with my FF and then installed it again. Right now, so far it’s functioning. But I’ll try to observe this thing first. I hope after erasing all of my records with my FF, this time, my right click will function both in my laptop’s mouse pad and with my cordless mouse. I’m now with using my Dynex cordless mouse again.
