No, quite the opposite - Jitsi worked for me on all browsers.
SfB requires an EXE plugin. Zoom same, although you apparently can use their web client with a bit of hacking (because they first offer EXE). To schedule meeting on both you need to be a registered user.
None of these issues with Jitsi. I link to jitsi.rocks because it allows you to select the closest Jitsi instance.
