Change the behavior of the icon in the address bar.
When you install the "Firefox Translation" add-on (https://addons.mozilla.org/en-US/firefox/addon/firefox-translations/) the icon show the translation bar and I need to go on the right over the X to close it.
I think is a good idea (like the icon of Firefox Container add-ons) to close the translation bar, when it is already open, by click on the icon in the address bar. And to open the bar when it is closed (like a toggle).
I hope this is the right place to post this idea. Sorry for my poor English.
Thanks who will want to support this simple idea.
