Does not process Credit Card payments
My Firefox has suddenly stopped processing my debit card payments to Tesco online. I have cleared cookies, history and everything I can but still the same. I fill in the card details and the site asks me to wait to get authorisation but nothing happens. I can do the transaction quite ok on Microsoft Edge.

If you use extensions ("3-bar" menu button/Tools > Add-ons > Extensions) that can block content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that such extensions do not block content. There is security software that can interfere with loading content, so check that as well.
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: "3-bar" menu button/Tools > Add-ons > Appearance
- Do NOT click the "Refresh Firefox" button on the Safe Mode start window
Hello, I am personally having the same issues that other have reported concerning the inability to process payments while in the Firefox browser. In fact, we have had to put a Notice of issues on our website to forewarn our clients of potential problems trying to make payments in Firefox. We use two basic payment gateways, PayPal and Square. The PayPal gateway offers no issues. However, no one trying to make a payment using our Square payment gateway (including ourselves) are able to complete the transaction.
This is NOT an issue when one (again, us included) uses any other browser, i. e. Internet Explorer, Chrome, or Opera. The error we receive is the same as the error other receive. You can see screen shot of error by following this link:
