Web Compatibility Support • Holy smokes - look what's working again! Proton Drive. And Proton Calendar is all better on PM

We last discussed this in October 2025 in this thread: https://forum.palemoon.org/viewtopic.ph ... ve#p265740

Proton had found the problem and promised to fix it in their "next update", but the months went by and there was nothing. Tried Proton Drive again today and it's working perfectly again!

And some old errors in Proton Calendar seem fixed now.

Have to try out their other web apps.

• Lumo AI isn't working, but I didn't expect that to work and haven't turned in a bug report on it yet. I should do that.
• Proton Pass looks perfect as usual
• Proton Docs and Proton Sheets give an "unsupported browser" message. Bit of a bummer. Maybe I'll bug report those just for the heck of it.
• ProtonVPN site looks correct
• Proton Wallet is a no-go right now
• and of course Proton Meet video conferencing isn't working with Pale Moon, but that's to be expected without WebRTC. Might have to try that in Basilisk.

Anyway - the basics are now working - mail, calendar, pass, vpn, drive. Progress!!
