I run Fraidycat in a separate Firefox profile which I don't use for anything else. If I want to hang onto a link from a feed, I'll just open it again in my main profile. I've found a side benefit in that the slight extra friction of opening a window for a new profile results in less frequent checking for feed updates, which seems like a good thing for me.

I also have my Fraidycat profile set up with the Temporary Containers extension, so that every link I open from my feeds automatically opens into an ephemeral container and nothing is shared. Doesn't protect against Fraidycat itself, but does keep things of only passing interest nicely hived off from everything else.
