Adware Issue?
 

I turn on my computer today and go onto the Globe and Mail on Firefox as I always do every day to check my investment stocks. Then the below shows up. It only happens on Firefox and only on the specific link site that I bookmarked. I try the same page on chrome, no issues.

I tried Eset and Adware antivirus and still picks up nothing. I even did a system restore to earlier point in time, still issue. What gives? Any thoughts guys? Not much information from google I could find. Stupid thing keeps popping up...

Im not really good with computer but it seems like you clicked on something that opened it up.
Maybe your bookmarks url have been changed?
or pop ups??

do a clean wipe of browser cookies and history and cache on firefox. should fix the isuse.

It seems like your browser was hijacked by some adware.
Try install and run Malwarebytes:

It's messed up, haven't been using Firefox so far at home.

Even at work computer, same thing happens. What gives...

I use AdwCleaner from BleepingComputer: AdwCleaner Download

Pretty powerful tool. One time job only.
