FF7 bug Rated 1 out of 5 stars

on FF7 it causes a problem where whenever you open your browser it doesn't open to fit your screen it opens in a window size. First I thought it was the new FF7 update tried to solve it nothing works but then disabling this add on finally did the trick!
To the developer, if you can fix this issue ..please do, this add on is pretty important to me.

Thanks for reply I'll investigate the issue
