I've just completed building a brand new PC and installed Windows 10 on it. I'd always used Firefox on my old system specifically for the Amazon Review Checker that automatically popped up in the browser when I opened an Amazon Product Page. I don't understand why, but this is not happening on the new computer. I've double-checked "about:config" and enabled everything to do with "experience2023" and it still won't work. I saw mention in other support posts that there is supposed to be a $ dollar sign icon in the address bar, but it is not there. I tried manually installing the extension but that just adds links to the Amazon page, that open in a new tab when you click them (I've since uninstalled the manual extension). I'm not sure why I can't seem to open the integrated Review Checker, can anyone help me? Thank you.
