Hi everybody,
I’m trying to sign in to Zoom using my SSO login from the university.
When I click on “Sign in with SSO” and enter my domain, the browser opens correctly, and I can log in via the SAML page of my university.
Then I am redirected to a “success” page, where the user should click a “Launch Zoom App”-Buttom
In theory if I press the button Zoom should open and process my token.
Unfortunately in Firefox or LibreWolf, my default browser, nothing happens, no matter how often I press the button.
This might be a question on what the browser is trying to do and how it was installed.
For example if the browser is installed as a distribution package, a Flatpak or Snap.
Could also be a configuration issue.
For me clicking a Zoom URL and have it opened by Firefox worked until some day and I have not yet figured out why it no longer works.
I am using Chrome essentially just for that
In my case, Firefox (or LibreWolf) no longer asks whether to open the Zoom app when clicking the “Launch Zoom App” button.
This is what I did:
Open a new tab in Firefox and go to: about:config
In the search bar, type: network.protocol-handler.expose.zoommtg
If the entry exists: Set it to false (right-click → Toggle or Reset). This will make Firefox prompt you the next time a zoommtg:// link is triggered.
If the entry does not exist, you can create it manually:
Right-click anywhere → New → Boolean
Name: network.protocol-handler.expose.zoommtg
Value: false
The next time you click on a Zoom SSO “Launch App” button that points to a zoommtg://... link, Firefox will ask again if you want to open the Zoom application.
