User.js: Do I really need "window.opener be gone", if I am using this user.js?
Do I need to install Firemonkey and suggested script?
I tried the test site and it was unable to make changes in opener tab.
Hence, I am assuming dom.targetBlankNoOpener.enabled is enough. Although this comment makes me think twice:
2429: enable (limited but sufficient) window.opener protection [FF65+]
(limited but sufficient)

Maybe it's the case of updating this wiki page to include a note, at least?

Personally I use the extension, as it never fails. @earthlng is the author (of both the script and the extension). My understanding is that the extension covers more cases where it could be used (but is probably rare?), but comes with the downside that you can't allow any domain exceptions. Personally, I've never seen an issue, and I think earthlng only ever found microsoft catalog to be problematic: but of course that is all anecdotal.
As for scripts, I think they're problematic and generally risky: also see #891 - which led E to put up the bit in the wiki that it's not reliable in GM
tl;dr: go with the extension and if you hit a problem with a site you sometimes/always use, re-evaluate (or use a different browser for that site). The pref is probably enough for most people

Does it mean the pref fails sometimes?

Can you give me a hint on what "enough" means?

No. I meant the script can fail (see #891). The pref shouldn't fail: if it does, then that's a bug

earthlng knows more about it - my understanding is that the pref only covers common use cases, so it's unlikely that what it doesn't cover will affect you, or at least rarely - but I guess without some real world studies, no-one would know for sure
As to what is not covered by the pref (but is by the extension, not sure about the script) earthlng can explain. As I said, I just use the extension since it doesn't fuck around, covers everything, never fails, and doesn't affect me (sites breaking)
