In Windows 10, in a tablet environment, things aren't working properly. I'm referring primarily to the onscreen keyboard. In Windows Tablet mode, an onscreen keyboard should appear in address bar and text fields. Firefox is killing that onscreen keyboard. The keyboard appears, but then immediately disappears. There also is a visual glitch occurring in the title-bar simultaneous with the killing of the OSK (on screen keyboard). This only happens in Firefox. OSK in MS Edge functions great for example. In desktop mode, but still physically in a tablet environment (Lenovo Thinkpad Yoga X1, folded, portrait mode for example), no OSK appears at all anywhere. This is not working well for me and will likely be a problem for others as we continue to approach the future. I truly hope that Firefox prioritizes Windows 10 tablet environments. It really is going to be important to many users.
