Can someone who is using the current Firefox version (115.4.0) please advise if there are any (connection) problems with Companion (as long as not Legacy is used)?
Companion has stopped working for me with Firefox for the first time in over 10 years. (Chrome works.)
For me, with the latest version of Chrome (119.0.6045.106, 64-bit), using Legacy leads to a browser popup window pointing to http://192.168.XYZ.X:8001/_proxy, and App Inventor would be stuck at 10% (Finding the companion) for a long time.
Firefox version 115 will be the last supported Firefox version for users of Windows 7, Windows 8 and Windows 8.1. If you are using these versions of Windows you will be moved to the Firefox Extended Support Release (ESR) channel by an application update. Mozilla will provide security updates for these users until September 2024. No security updates will be provided after that date.
