Hello, I love using Firefox. I've used it for years. However in the past year or so it is getting increasingly difficult to cling to using it as I'm finding that more and more websites don't like it. I cannot use it with my bank https://www.simplii.com/en/home.html. (when I go to sign in I end up in an ever ending loop where it just takes me back to the sign in page. I can't use it with some shopping carts. On this site (as it is one I remember) https://amaranthstoneware.ca/, If I put one thing in the shopping cart, it is fine, but if I put a second thing in, it doesn't remember the first. And now I was trying to watch a video from the National Film Board https://www.nfb.ca/film/affairs-of-the-art/ and the video buffers constantly and I miss words as it catches up. A fellow from the NFB gave me a special link to a vimeo video and it wouldn't load at all. https://vimeo.com/787578864/10f72d40e4  Just the spinning circle. All of this issues don't exist with Chrome (the site I did try it on). My version of FIrefox is up to date. I use Duck Duck Go and LastPass but I turned them off to test and it didn't fix the issue. I really want to continue to use Firefox, but it is getting hard with so many issues with it. I hope you can help. Thank you for your help.

You can check for issues with Total Cookie Protection.

This issue can be caused by corrupted cookies or blocked cookies.

  • check the permissions for the domain in the currently selected tab in "Tools -> Page Info -> Permissions"

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

  • click the shield icon for more detail and possibly disable the protection

You can check the Web Console for relevant-looking messages about blocked content.


You can try these steps in case of issues with webpages:

You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • hold down the Shift key and left-click the Reload button
  • press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • press "Command + Shift + R" (Mac)

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings).

"Remove the Cookies" for websites that cause problems:

  • Settings -> Privacy & Security
    Cookies and Site Data: "Manage Data"

"Clear the Cache":

  • Settings -> Privacy & Security
    Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
