I am told by a friend that he has arranged two meeting today first for 15:30 the second for 16:00 nothing has arrived on my laptop or email what has gon wrong

You deserve a zero for non-existent support.

I do not understand how to use it. There are no instructions.

This extension doesn't offer much as it requires the Zoom client to be installed on the machine to start or join meetings.

difficult to navigate

Not sure if it's new, but it takes over the default save button for adding a google calendar event and makes it "Make it a Zoom Meeting".

Doesn't work with latest firefox, even when signed in it doesn't show the "make this a zoom meeting" button. Please fix it!

Doesn't work anymore (latest firefox on linux)

Not working anymore on Firefox version 108.0.1. Did all the trouble-shooting that I found online. Disabled & enabled the extension, checked all settings, restarted browser, restarted workstation, logged out of all other tabs in also on all other browsers incl. the Thunderbird google calendar view, where it never worked, cleaned browser cache, ran a bunch of other cleanup software, but it keeps working on Chrome browser and just not on Firefox anymore, since the latest Firefox update today. Most crucial function for my business event planning hence if it was actually working flawlessly, I'd give it 5 stars!
