Allow caa: URLs to be clicked (through to the Classic Add-ons Archive)

[grahamperrin]

At https://github.com/RandomEngy/RehostImage for example we have a caa: URL,

• caa:addon/rehost-image

– added in response to RandomEngy/RehostImage#10

Enhancement request

Please: can Waterfox be enhanced (with an about:config preference) to automatically link caa: URLs?

Why in Waterfox, not in an extension?

@JustOff re: http://forums.mozillazine.org/viewtopic.php?p=14809593#p14809593 (quote below) I assume that the enhancement will be not (or not easily) achievable in the Classic Add-ons Archive extension.

AutoPlainTextLinks won't make a URL out of something that Firefox (or Waterfox) wouldn't ordinarily treat as one when manually selected. If you try select it manually and then right click, then if you don't get the "Open Link" context menu items, AutoPlainTextLinks wouldn't be able to add them.

I just realised … in multi-process mode, whilst the Tools menu approach to caa: will open a new non-e10s window, manually entering a caa: URL will not.

I'm aware of the incompatibility with multi-process but until today, I didn't realise that manually-entered URLs were affected. This almost certainly means that making links clickable will be (ultimately) frustrating for most users so I'll close this issue, wontfix (unless someone can submit a PR to fix JustOff/ca-archive#2).
