I took away one star for the permissions, BUT..............
Compared to the other gesture addons this is the best. i.e. Gesturefy states they DOWNLOAD files and read and modify the browser’s DOWNOAD history. Why are they worried about what i download?

Anyway it works without the added concern.

With this addon enabled, Firefox loads the CPU by 15-20%. Sorta miner?

Fantastic. I was also a FireGestures user for years past and it's so ingrained in the way i interface with firefox I can't live without my gestures.
I found FoxyGestures to be an improvement on FireGestures, giving me everything I needed and more. Thank you for creating this addon.

not bad, but seems certain pages can't use gesture? like this one...

Excellent extension. One request: Please make the "Close Other Tabs" gesture works as default Firefox behaviour. Currently Foxy closes all other tabs without any warning. Thanks!!!

thank you for recreating this long time awesome addon

Seems to work, but one drawback make me to uninstall this add-on. After the gesture "Back" - move mouse from right to left it seems that something makes the status of "Ctrl" key as "pressed infinitely". So after this gesture the mouse wheel works as the Zoom In-Out of page instead of normal scrolling. Maybe I should change something in add-on options, but I have not found anything to correct this problem.

If you are looking for a quality mouse gesture addon, look no further!

I like this extension.

It would be great if you can add 2 more built-in commands: go to first/last page in current tab history. Currently, I can make it work by making use of user scripts like below:

/* go to first page in history of current tab */ for(let i = 0; i < window.history.length; i++) {window.history.go(-i);}
/* go to last page in history of current tab */ for(let i = 0; i < window.history.length; i++) {window.history.go(i);}

Besides, I noticed some comments saying thie extension doesn't work on firefox's pages (like this one). This is not the limitation of this extension. It is the restriction introduced by Firefox on ALL extensions. And it can be bypassed by about:config:

extensions.webextensions.restrictedDomains (empty it, create this string first if it's not there)
privacy.resistFingerprinting.block_mozAddonManager (set it to true, create this boolean first if it's not there)
