Hello! As of recently (within the past couple months), I was able to go on Petco.com from a desktop. But now, every time I try, the website doesn't load correctly. It jumps on and off about 100 times a minute and never stops. This does not happen on all other browsers. Something is wrong somewhere. When trying to log into Petsmart.com from a desktop, something different happens. It does completely load but when I try to log in, it will not log me in! I am able to log in on all other browsers. The third website, Rakuten.com, same thing happens like Petsmart.com . It loads but when trying to log in Rakuten.com I get: Oops. There was a problem. Please refresh page and try again. BUT AGAIN, I am able to log on on ALL OTHER BROWSERS. Is there a fix for this for Firefox? Please let me know if you can fix this or this is the way it will be for these websites. I have been using Firefox for years and like it the best! Never had this problem. Thanks!
