Add-on summary
Adds a download button to the youtube.com/feed/channels page. It exports the listed channels as an XML, in a fashion it used to work in Subscription Manager. You have to log in to your Google account beforehand, of course.
It's open-source, you can have a look at what's under the hood: github.com/ajohntom/tube-sub-export
User reviews
I see no button on the page.
PS: You should note in the description that the click from this page https://www.youtube.com/feed/subscriptions DOES NOT WORK (still does not work in 0.1.4 w/o page reload). User must to directly input link: https://www.youtube.com/feed/channels

It's a shame we have to undo what Google has done for managing subscriptions in YouTube but this app helps. Now, if I could figure out how to get it into an OPML format for importing into Feedly and Thunderbird...
Thanks for the response but every time I try to load the file into an OPML reader (i.e., Thunderbird or Feedly) it tells me it's an invalid OPML file.
