Did you go to Customize and add the button to your toolbar area?

Guess what? I didn't have RestartFirefoxButton_Movable.uc.js in the Chrome folder after all. Dumb.

So happy. Works fine. Been hoping to find this type of restart option for a long time now.

In past custom button setups, it was possible to source the button image from a local file. I still have the previous RestartFirefoxButton_Movable.uc.js. The section of that file pertaning to the button starts with

var dataUrl = "data:image/png;base64," +

after which the base 64 code is added.

Can someone tell me if this can be done, and if so, how?

Thanks

I just upgraded to Firefox 89, and the restart button icon changed

Firefox 88.01

FIREFOX 88 01 RESTART

Firefox 89

FIREFOX 89 RESTART

Is there a way to bring it back?
