Cannot use Jitsi Meet with PureBrowser (user agent issue?)

Steps to reproduce:

• Open PureBrowser (46.2.0esr+really45.4.0esr+pureos-1pureos2)
• Visit https://meet.jit.si (or a room, like https://meet.jit.si/MacabreVegetablesDiscussRapidly )

What should happen:

• Page loads
• Prompted for WebRTC access (microphone and camera)
• Able to take part in a meeting

What happens instead:

• Page does not finish loading (grey background, favicon visible, nothing else)
• JavaScript error in console (looks like it’s related to user agent, see below)
• No WebRTC prompts

Notes:

• PureBrowser is a fork of Firefox for Pure OS. It has a user agent of “Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 PureBrowser/46.2.0”

• Related report here: https://tracker.pureos.net/T201

• Confirmed that media.peerconnection.enabled (under about:config) is True

• Successfully prompted for WebRTC access (microphone and camera) when visiting https://test.webrtc.org/

• Console error message (when visiting https://meet.jit.si ):

Yep, looks like an extra check would be needed in order to treat PureBrowser as Firefox. The logic will probably need to go here: https://github.com/jitsi/lib-jitsi-meet/blob/master/modules/RTC/RTCBrowserType.js if you’re up for witing a PR 😃

This issue is resolved in PureBrowser 52.5.0
