Before the Quantum update, swiping sideways would highlight text in Firefox, and double tapping would highlight a word, pretty much like how a mouse pointer behaves or even the default Windows notepad behaves with touchscreens. This was great and very convenient for me for browsing lots of sites without having to use a mouse. I don't know how to restore that (or if its possible even) since disabling the cellphone-like teardrop carets on about:config doesn't change anything. Any help would be appreciated and if its currently not possible, I would like to know how to request that as a new feature (which really is just restoring old behavior) since many other people using touchscreens seem to miss the old behavior. Thanks.
