Greasy Fork

People are complaining in my script that it does not work.

Indeed this is userscript manager issue (Tampermonkey latest version requires developer mode)

Can Greasy Fork do something to guide the users that the userscript not working is because of this?

window.external.Tampermonkey.getVersion((r)=>console.log(r))

This can show TM's version. I think base on the version, there can be warning messages to be shown during installation in Greasy Fork.

Based on changelog and issue644, the version to MV3 should be >=5.2.6195

For example, for TM VM3 >=5.2.6195, show a warning message first. users can select do not show again.

It seems to me this is more of Tampermonkey's responsibility...

I can maybe include a link to TM's docs in the general user script install instructions.
