Great extension, works perfectly for me

# Lacks: interception of RSS and Atom URLs, prevents other extensions from loading on its preview pages

I need "Disable context menu" option.

Look in your address box for the icon. If there is a feed, you'll see it. If not showing, then there is no feed. Simple. Popup under it is also clean looking and simple but effective. Good tool. I use it to grab feed url for QuiteRSS on Linux Mint Mate 20. All good.

It just works. The icon needs to be tweaked to appeal to the eye.

Simple, useful and light.
One suggestion, the tab icon is hard to see in a dark theme like mine:

Please use the same gray of URL icon.
Thanks.
