Somehow I got firefox.com when I clicked a link on the extension’s page to write a review. I had to create an account which I subsequently verified. I enabled cookies.
I wasn’t able thereafter to find any link for writing a review. I was sent back to the page for the web extension I had been looking at and there was no link there. I tried loading firefox.com independently of the web extension page and could find no means there of writing a review.
On the extension’s page there is an arrow pointing down. If I click that I get a dropdown menu with a variety of options (none of which are pertinent) ending with the option to “log out”. There is a long alpha-numeric string beginning with the word ‘anonymous’. If I hover over that I get the dropdown menu but no option to post a review.
I should add that two items in the dropdown menu are greyed out : My Account, Tools.
