'Both Edge and Chrome already allow users to try unreleased, experimental features (by typing about:flags in the address bar). Soon there'll be a similar "Firefox Experiments" option starting in Firefox 79. Slashdot reader techtsp shares this report from the Windows Club: Mozilla has a dedicated Experimental Features page on MDN just for that. But limiting experimental features to Firefox's Nightly channel has a limitation: A fairly limited number of "curious" users. Now, extending some of these experimental features to stable releases will increase the scope of "Firefox Experiments" as a whole... This option will allow users to enable/disable experimental features under Preferences... [In Firefox 79] Navigate to Preferences by entering about:preferences in the browser's address bar or click the gear icon and got to "Preferences." Discover and set browser.preferences.experimental to True. Now, you should be able to see the "Firefox Experiments" menu under Firefox 79 Preferences.' -- source: https://tech.slashdot.org/story/20/06/27/0321206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
