When ordering on line, I click continue to get to next window and won't continue and shows a line at bottom with "true... false...true" and won't go to next window.

Question

When I go into any website to make a purchase, when I click on continue to go to the next window, nothing happens. I wexploreron't go any further. I get a long list of numbers and letters with true false true in a banner at the bottom of screen. I have tried to click on the banner but disappears when I go to put the arrow on it.
This all started when I was on a government website, hit back arrow, and lost the site. Ever since, I have not been able to conduct any business on Firefox and have to resort to using Explorer to do my business. Explore works but not FireFox.
Thank you!
