Decent little extension. Works and works very well. I wish the icon were updated, it looks a little dated. Other than that, perfect!

I used to always have to go to firefox settings to clear the cache when I was changing things on my website. That was frustrating when I made small changes. This is a lifesaver.

It's great

Please create an option to disable F9 since this is also the shortcut do activate the Firefox read-mode.
