Looking for something?

When using the Amazon website, when I click accounts and lists, it says page not found. It works fine in Safari. Since FF80 came out, many addons have been having trouble. Such as speeddial, where I've been in contact with the developer and he's says there'll be an update in 2 weeks to fix it. Adblock was playing up, allowing acceptable ads, not allowing access to prefs from the toolbar icon's gear, and only sometimes allowing access to prefs from FF-Tools-Addons. But today that is working. Amazon had been working fine until today, when it wanted to use those annoying "I'm not a robot" things to get me to sign in again. I rang up. Cleared cookies etc. But still had the problem. I had addons that re-directed me from amazon to smile.amazon I've disabled that. I've also disabled the Tampermonkey addon which I'd used to redirect to smile.amazon {and also remove Youtube end cards.} But still, when I'm on amazon, and I click on accounts and lists, it says page not found. I can hover the cursor over the accounts and lists bit, and from there I can get to my lists, orders, etc. But still not my account. I get: Looking for something? We’re sorry. The Web address you entered is not a functioning page on our site. Click here to go back to the Amazon home page This is getting beyond a joke. I've tried to check on the macbook downstairs, and it's the same problem. Worse, now when I start to type amazon into the search bar, it brings up amazon.com as the default, not amazon.co.uk as before. {And is still working here.} I have no idea what's going on. But somehow it's all broken. Any ideas?
