Update: Native smooth zoom is starting to appear in newer Firefox builds. Try enabling it by going to about:config in the url and setting apz.allow_zooming to true. If that works for you then you don't need to use this plugin :) --------- This extension adds support for smooth zooming with the pinch gesture on a trackpad. It's been designed to match the behavior of Chrome and Safari. Make sure all the "browser.gesture.pinch" settings in about:config have been reset to empty, otherwise it wont work properly GitHub user QWERTYUIOPYOZO has recently developed Windows touchscreen support, please test it out and leave feedback on GitHub :) Non-multi-touch users can still smooth zoom by scrolling and holding down the SHIFT Zoom can be reset by pressing ⌘ and 0 on macOS or CTRL and 0 on Windows It will not work on this page because addons are disabled on the addons website Requires Firefox 55 or greater Report issues and see more details on the github repository: github.com/haxiomic/firefox-multi-touch-zoom
