Summary of known Firefox issues on Ubuntu 24.04:
All browser automation that does not need the XModules works fine in Firefox, too. But there are some XModules related problems:
- Regular Firefox V138: Computer Vision XModule not found
- Firefox 128 ESR (Extended Release): All XModules detected ok, but XModules mouse clicks are not executed.
These bugs are Firefox specific.
So for now, please use Chrome on Ubuntu for RPA automation.
Alternatively, if you want to use Firefox, you can use the older Ubuntu 20.04 LTS (Focal Fossa), everything works fine there.
