EDIT
This issue may be due to WebRTC being disabled. WebRTC is required for google meet, but also used for fingerprinting.
Recently I tried to join a google meet meeting in my hardened config firefox browser, and google meet didn't let me in at all. I was confused as hell. I could join only on my phone, but not any of my three computers I tested it on. I then went into a virtual machine with regular firefox(also linux), and the meeting works. The only conclusion I can draw is that google is so desperate for my data that they refuse to service me unless I give them this.
This post intends to inform people that issues with google products may be related to their valid wish for security, and the actions they have taken in pursuit of that. The post also intends to inform people of a solution. The two apps that I recommend are:
- Jitsi Meet: This is self hosted, but you can also make a meeting with jitsi's own servers. A excellent alternative to google meet, the only reason I didn't use it is that I had issues the day I needed to meet, and had to fall back to google meet instead.
- Jami: This is a distributed-network chat and video calling app which is open source and a GNU package. It does require an app, but is free and open source and will serve your purpose.****_________
I don't know if it's related, but I noticed very recently Google sheets quit working correctly on Firefox.
Try: gfx.canvas.accelerated = false. There is a ff bug since a few months that causes various apps, including all kinds of google docs to malfunction severely, and this setting works around it.
Apparently I already have that setting turned off so I'm not sure what the issue is. I've been having issues with the overlays like "find and replace" and "sort range" not appearing. It just randomly broke recently with no apparent change to plug-ins so I'm not sure what's up. I haven't bothered disabling plug-ins one at a time to see if one broke it.
