For the past few days the website 'dictionary.com' does not load on Firefox (I'm using a laptop with Windows 10). The screen reads "Unexpected Application Error! aN.findLast is not a function". I've deleted all cookies and caches, but the problem still is occurring. Help!

It loads without issue for me. Try restarting in troubleshoot mode.

That may fix the issue without more but, if it persists, you need to test your extensions. If none are at fault, try right-clicking the site in History then Forget about this site. Make sure you have a backup record of your user name and password before doing that because they will be forgotten also.
