Please understand my query. I removed the Firefox completely out of my computer, went into Regedit.exe (Please don't go in it unless you have used it frequently and know the consequences) and removed it as through as possible, when I get done there was nothing left in the computer of Firefox not even a single file or a string. Then I installed again and every website works fine, but if I log into my Firefox account only after that everything disappears, then if I open a new private window everything works fine again It seems to me the problem is my account in Firefox server. But I do not have access to it. I have it on two of my cell phone and 2 other computers but this is the newer one I use the most and only on this one I have problems I am signed in all my devices and they all work fine, I already checked the computer with different Antivirus programs and have also change my router
