Firefox never ever loads groupon.com without locking up. Firefox freezes, hangs and immediately says (not responding) for several minutes... ALWAYS!!! Once Groupon.com is loaded, anything you click on then freezes/ hangs. No other website has this problem. None! Just Groupon.com It takes on average 3 minutes to load the page. Then 3 more minutes to load anything you click on, on the site. The Groupon app on my phone works like lightning... But go to the Desktop computer to print out a purchase and you're there for a half hour trying to get on the website HANG, sign in to the website HANG, get to your purchases HANG, see your purchase HANG and print a receipt HANG. Ya'll might as well be prepared to camp out on the computer for a day if you have to print out several Concert tickets! This has been happening in every version of Firefox for more than a year. Mozilla, please, please fix this issue on my most prized Browser!
