@Peder the icon is no longer showing up in recent versions of Firefox.. any chance you can fix it?

This is a great addon, though it doesn't work anymore :<

Since the last update of Firefox (58) the reload button no longer appears on the extension page or options page. That is a problem for me.
And the trick with user.css to maintain the button on the right of the address bar doesn't work to.

I try to modify this "browser.pageActions.persistedActions" in about:config

This
{"version":1,"ids":["bookmark","bookmarkSeparator","copyURL","emailLink","sendToDevice","canvasblocker_kkapsner_de","_owl-comfortable-reading-addon","_e1ed7a80-7c11-4f7e-968b-79b551a0067f_"],"idsInUrlbar":["canvasblocker_kkapsner_de","_owl-comfortable-reading-addon","_e1ed7a80-7c11-4f7e-968b-79b551a0067f_","bookmark"]}

To this

But it does nothing. I know it's a little bit persnickety but I really want to have it on the far right of the URL bar.
I'm pretty newbie in coding and programming stuffs so I'm trying steps by steps. If anybody can help it will very welcomed.

If nothing can be done to remedy these two points I will give up the add-on to use the default reload button, outside the URL bar... Sadly.

Works but it would be nice if "go" would also be implemented.

Also it would be nice if there would be a way to move it to the end of the address bar if this is used:

So a css class would be nice.

Good addon but the button is off center, any way you can make it more aligned?

Works as documented, however the .svg doesn't pick up the inherit the css color as other icons do, so it doesn't blend well with themes.
