Hi, your link works for me in the UK using Firefox 76.0.1.

  • If that doesn't help, disable any ad blocker you may be using then reload the site.
  • Try deleting ALL references to the Barclay's website. To do that, open the 3-bar menu > Library > History, then click the Show All History link at the bottom of the list to open the History-library window. Search for Barclay's by typing it into the Search History field in the top-right corner. Now in the search results, right-click on Barclay's, and select Forget About This Site. (Browsing and download history, cookies, cache, active logins, passwords, saved form data, exceptions for cookies, images and pop-ups for that site will be removed). Give it a few minutes to complete the deletion, then try the site (not from an old bookmark) again. More - Delete browsing, search and download history on Firefox.

If it works in Safe Mode, disable any theme or extensions you have - 3-bar menu > Add-ons > Themes/Extensions, then restart Firefox; now if it's still OK, re-enable them one by one until you find the culprit. You may need to restart Firefox after enabling some extensions.
