Why am I getting this white line completely around Firefox? I did a reset last night and it seemed to have disappeared but it's back again today. I think it may have started with the last update. It seems like with each new update comes new problems. Some days Firefox doesn't work at all for me. Firefox has always been the browser that I have preferred to use but it's rapidly becoming unusable for me. The white line is just cosmetic but Firefox is also plagued with tons of functional problems that keep getting worse. Is there a paid version that actually works?
