Hello! I have a Acer One 10 tablet with the latest windows 10 update 1809. The update installed flawlessly, but after that, Firefox stopped popping up the windows 10 on screen keyboard. I choose Firefox over Chrome because Firefox automatically calls the on screen keyboard on every text field. I also have A Microsoft Surface Go, but the same windows update on that device failed for some reasons, so I cannot verify if the culrpit was the update itself. But I guess it is because I did not install anything else or changed options. I already checked in about:config if the path of the .exe file that triggers the keyboard was still correct and it was. My skills can lead me to this point. NB: Firefox is updated to the latest versions on both devices. I really do hope this is a solvable problem.
