Last Firefox install starts offering to add “Evernote Web Clipper”.
However after installation, the offer is still there.
Would be much nicer for the user if the page detected when the add-on has been installed and change to a Thank you page or at least remove the link to the Web clipper Add-on. I happened to me that I installed the add-on and then looked at the page and had to go to the complements area to certify it was really installed as the still offered installation. Actually, this is happening to all install Add-on pages I think,
