i have cell phone lg k20 plus with Firefox 57 , when i try to visit zamplebox website , it loads to about 75 present , them freezes . i don't understand why . it never did that before . even the hyper links freeze , nothing works , except the square box on the top of the page were the number of pages that are open , lets you back to the last page , nothing else works , you can close the window , but when you reopen Firefox , its stuck again . now what . you cant change nothing because the whole page is stuck . cant figure it out .
