I use Inoreader, which is a RSS feed reader, and it has an extension that allows me to save pages in my "read later" list.
I can never stay logged in the extension on Orion. If I click on the extension, I get the pop-over below, then I get brought to their website, sign-in and in other browsers that's it. But here whatever I do I am never logged in the extension.
I wanted to try the compatibility mode but I the feature to allow a specific extension to work in compatibility mode has not yet been done. I don't think the issue would be from one of the other extensions I have installed though, because I kinda have the same ones configured the same in other browsers.
