This has somehow gone under my radar, and coincidentally I've been wondering in the shower a while ago whether it's possible to have an NPAPI plugin that loads a different browser engine...

Works great for my Discord btw! I can paste images and even join a voice chat and listen to other people speaking as well as watch someone's stream... Mic and screen sharing don't work but I don't care much about them, as long as I can join watchparties with this I'm fine with it! :thumbup: I suppose the only thing I can complain about is the lack of picture-in-picture mode (which I use to make the discord stream I'm watching larger than my viewport).

Anyway has this not been reviewed for the Add-ons site yet? It would be impractical to store the whole xpi in the APMO server, but an External listing should still be possible.

Something like this (but better) should be an official Pale Moon team addon, because whatever new standard they add, javascript engine will still be too slow on heavyweight sites (almost all popular sites).

I think something like this as a substitute for rendering whole webpages being an officially sanctioned add-on would be a bad look for the browser. It's pretty much admitting that there's no point in updating the Goanna engine as well as our own SpiderMonkey. I'd like something that only renders user-specified iframes in Chromium instead. One of the common causes of websites being slow is due to the amount of youtube and twitter iframes embedded within a page, and both of them notoriously perform badly for us if many of them are loaded at once. If instead they're offloaded to an NPAPI plugin and the rest of the webpage is rendered by Pale Moon then it would lend credence to the rhetoric of Chromium not being a web browser but its own runtime environment, like Flash and Silverlight were.
Ah good to see it approved then. "SubWebView" doesn't return any results in the search though, I think the author should add some indexing keywords. Also it's one version short from the latest one in GitHub (1.0.4 vs 1.0.5).
