Firefox for Enterprise Community Forum

We've been noticing for some time now that we haven't been able to load the Microsoft Bookings Page using the Microsoft Store version of the Firefox web browser.

Here's what we have tried and what we know: -We cleared cache and cookies using the "Everything" drop down option to no avail. -Confirmed that we are running the latest version and no extensions are running. -Tested running it in "New Private Window" to no avail. -Tested Diagnostic Mode to no avail. -Tested Refresh Firefox to no avail. -We confirmed that we are able to login and load the Microsoft booking page using different browsers (Edge, Chrome and even Firefox directly from their own page) with no issues. - We confirmed that different users can replicate the issue and can be replicated on a different computer as well. -We confirmed that we are able to access other Office 365 web apps with out an issue on the Microsoft Store version of the Firefox web browser.

Microsoft Support stated that they are able to replicate the issue on their end, but advised to reach out to Firefox support to investigate this further.

Feel free to let me know if any other information would be helpful such as .HAR log file(s) etc.

Thanks!

I need some help to get Intune Firefox Extension Management to work.

I have imported the Firefox ADMX into Intune but cant seem to get the JSON correct for this to work correctly.

The scenario I would like to give is I would like to block all extensions but allow Power Automate Extension and Cisco Web Ex Extension.

Any help would be appreciated!
