Running Firefox & Thunderbird through a webserver?

There is KASM VNC, which easily allows to run whole Desktops or single Applications through your Web browser.

I think they use NoVNC or something. There is support for single Wayland applications, but I dont know currently how good it is and its a bit bloated for this specific use case.

Idea: Firefox and Thunderbird use Web Technology to display, dont they? The Browser is completely configurable with CSS. If there is something missing please add.

So you wouldnt need a traditional system and an X server / wayland compositor, but your browser could handle the compositing?

You would then need additional stuff

• shared storage for downloads
• redirecting local downloads to your browser, like KASM does it
• login interface to access the "website"
• some form of multi-user access, not sure if this is supported at all.

Why? Office 365 has this with Outlook, and Outlook is nowadays a Webapp afaik, just running locally.

It is useful to access

• a secure browser
• a configured mail app with many accounts, good interface, calendar, contacts, PGP, etc.
• you can use thunderbird from Tablets
• You can have an isolated Browser

This may be duplicating KASMs effords, but I think it may be really cool and better for these two apps, IF they actually use Web technology only.
