Chrome extension not working for web pages

I’m looking at a web page: Washington Times

The right-click menu for “Read in Language Reactor” is available on that page:

But when I select “Read in Language Reactor” I next see the message within Language Reactor that the browser extension is required. Then when I click “Browser extension required for this feature” I see that it’s already installed.

All permissions for Language Reactor are switched on in my browser settings. How can I get Language Reactor to work for me with web sites? Any advice will be appreciated.

Thank you,
Len
