There is a blog post from February 2021 announcing the dropping of Firefox support:

https://blog.zencastr.com/blog/2021/2/16/zencastr-is-launching-video-recording-into-open-beta

It says "... we found that many of the APIs that we needed to make the highest quality audio and video in the most secure way possible are not currently supported by Firefox." but does not say what those APIs are.

Thank you for reporting this issue, I was able to reproduce it. The website displays the Unsupported Browser message after you create a room and then try to access it.

Tested on: • Browser / Version: Firefox Release 124.0.2/ Firefox Nightly 126.0a1 (2024-04-07) • Operating System: Windows Mac OS

Notes:

1. Reproducible on both Firefox Release and Nightly
2. Not reproducible on Chrome.
3. Reproducible regardless of settings of Enhanced Tracking Protection

Steps to reproduce:

1. Create an account and log into it.
2. Tap on the "+ New" sign on the top right corner and select room.
3. Create a rrom and try to access it.

Moving to Needsdiagnosis.

I've moved this to bugzilla for further tracking: https://bugzilla.mozilla.org/show_bug.cgi?id=1899831

I'm reopening a little bit here. Safari has the same issue where it is said that Safari is not supported on Zencastr.

• Firefox https://bugzilla.mozilla.org/show_bug.cgi?id=1899831
• Safari This is also tracked on rdar://64578001 at Apple.

I wonder if @lmcarreiro and @filblue can help us better understand what are the limitations or put us in contacts with the right persons.

Through contact with the support, we got a generic answer about the issues.

On the side of Safari, it seems that Safari now "supports everything Zencastr needs for the recording tool, primarily the Media Recording API and the File Storage API". But there was mention that the "differences in how you support it are significant enough that it would require non-trivial effort to make our app compatible with Safari".

I'm pretty sure both Firefox and Safari teams would love to hear about the specific details of what is breaking. Not asking specifically Zencastr to modify the implementation but to really understand the differences.
