Jabref chrome extention

I tried everything to make chrome extension work without luck. Followed all instructions here: Browser Extension | v5 | JabRef, Read all past threads etc.

I just get the following when I click the extension, and nothing else happens. I clicked the first tab to check if it was a visual glitch, but that just opened a new tab. I have attached
a screenshot of my problem.

I cannot see the screenshot.

Sorry, I forget to upload that. Updated now.

Can you add some more infos? (e.g. from about dialog in JabRef)
