When I search for something and open a Reddit post with recommendations, I might select some text (ex. the name of a recommended thing) and drag/drop them into the new tab area to look each one up.

Reddit blocks this when you are not logged in. I don’t want to be logged in, especially when I’m on incognito or a firefox container since I’m shopping.

Here is the specific UBlock Origin filter you can add (click the popup --> click the gears for Open the Dashboard --> My Filters tab)
