Nobody here commenting on the fact that Slack blocks Firefox as well for voice/video calls?
I'm not a regular Slack user, but when I tried the voice call option earlier this week first I got a notification that they were switching to some new style of video conferencing called "Huddles", and it gave me an option to choose between "huddles" and "classic" video calls, which was confusing to begin with. I choose the latter, but I got a compatibility error with my browser, advising me to use huddles instead (really, they couldn't detect that earlier?). Anyway, when I tried to 'huddle' my customer, it simple said my browser (Firefox on Linux) wasn't compatible, and that I must install Chrome to use the feature.
This is where I closed Slack and used my phone to make the call.
It doesn't "block Firefox", it just doesn't work because it uses some now-deprecated experimental APIs for it that Firefox never implemented. The whole video stuff was kind of a mess for a time with different browsers implementing different things. This is probably why you shouldn't use experimental APIs, but people want features, so...
This was the status last time I used it a few months ago anyway; I believe they were planning on fixing it – they will have to sooner or later, since Chrome will remove these APIs at some point.
