On macOS there is a native affordance for this by using force click. It's kind of annoying that Firefox chose to not support this and instead made it click-and-hold only.
I agree with the other comments that say it's not discoverable. I've been using MacOS for 10 years and I didn't even know that "Force Click" is a thing. This comment caused me to look it up and then try it.
I disagree that it's "everywhere". I just tried it in Spotlight Search (Command + Space). I can never remember how to see where a thing is located there and I hoped a force click might show me. Hint: pressing command will do it but it takes 250ms to 500ms to show up and somehow I never wait that long.
Not only does Spotlight Search not show me where it is, force clicking doesn't show me a preview, or seem to do anything else.
In Finder force click edits the name of the item you're clicking. So, this doesn't seem to be terribly universal.
I suppose I'll slowly figure out how this works now that I'm aware of it.
