For Firefox, this is a duplicate of bug 1312376. The fix/workaround is to use environment MOZ_USE_XINPUT2=1 or MOZ_ENABLE_WAYLAND=1 in your /etc/environment.
For Tor Browser, if that did not come from Ubuntu then we can't track its bugs on this site. For LibreOffice, there doesn't seem to be a bug for this yet that I can find, so this bug is now about LibreOffice. ** No longer affects: firefox (Ubuntu) ** Tags added: touchscreen -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903632 Title: Touchscreen can't be used to scroll anymore.
