Well, it just doesnt work on LinuxMint Firefox. Just keeps on trying to connect. Of course I have provided the flag in my client config.
Doesnt work on Chromium browsers either. Thanks for wasting my time. Apollo is great, this extension sucks.

Simply does not work in firefox, no new tab appears, only the Stack Trace is added when looking into a request's details

This seems to do nothing in Firefox. I see nothing added in the Extensions section nor in the Developer Tools tabs.

I wonder if all these 5 star reviews were given by the apollo team itself. This addon doesn't even work on firefox. Even the screenshot in the addon page is a chrome screenshot.
