with every secondary (safe mode) restart of firefox or every second restart of firefox the safe mode is checking if u want to open some or all the tabs u opened in the last session ... at this stage only one mouse gesture is recognized ... the left click ... through which u pick up the tabs desired to be opened ... if u bypass this step and go forward the mouse gestures will come back to original firefox ... this is my guess, is not because i am developing this add on, perhaps if ur fiirefox crashes many times u need to restart it and this is why safe mode is recommended by firefox and mouse gestures are reverted to their basics ... i wrote this before even checking this add on ... i will do it now and guess it will work fine ... a previous version of this add on haven't received yet complaints and i guess if that time it worked ... then will work now again, but better :)
