v1.6.19 broken by firefox 18.0(.1) enhanced HTTPS security fix Noté 4 sur 5 étoiles
if you upgrade to Firefox 18.0.1 and enable the optional HTTPS security enhancements mentioned in the 18.0.1 release notes, then FireGestures will not recognize ANY GESTURE at all and the options in the advanced configuration window will be blank.
The only way to get your gestures back is to disable the enhanced security (reset the two preferences below to the current, potentially insecure defaults = "false"), and then restart the browser.
item from the release notes: Disable insecure content loading on HTTPS pages (bugzilla #62178) (btw, that's a 12-year old bug ticket, recently fixed)
security.mixed_content.block_active_content (default FALSE) -> TRUE
security.mixed_content.block_display_content (default FALSE) -> TRUE
setting these to the new recommended secure value, TRUE, will break FireGestures at the next browser (re)start.
Currently for FF 18.0.1 the default value for those prefs is still "FALSE" but from what i read on the ticket, the plan is that in a future firefox version the defaults for these will be "TRUE".
