One user discovered an add-on was causing problems.

Donthavecow, I resized to 110 and back to 100. Right side doing the same with both settings.

Now check this out - this morning when I turned on my computer and started to browse, a pop-up surfaced and asked to restart my computer. The system did it by itself without me typing. I searched under my account and it appears Mozilla/Firefox did something - don't know what. Now the right side is working again, but i don't for how long.

FredMcD, would you happen to know which add-ons create this issue for future diagnostics? I don't link to any third party software except my antivirus.

I don't know if it was Firefox that caused the reboot. I never heard of something like that.

I don't remember what is was.

That the problem is gone is good news.

I was concerned about the reboot and, like yourself, never saw that before. I attached an image. Right side, highlighted in blue was completely non functional. Thank you guys for replying back.

Is the problem gone?

. . . Now the right side is working again . . .

Donthavecow, the key functions, on the menu bar and elsewhere on the screen, worked on every site visited. Why it stopped, I'll never know. Never had this happened before.

FredMcD, yes, somehow it fixed itself...

Thanks again, everyone...
