Hi ! I don't know what you mean by 'getting a mixed version' - could you be a bit more specific ? Maybe this will help : https://www.mozilla.org/en-US/firefox/57.0beta/releasenotes/ https://blog.mozilla.org/blog/2017/09/26/firefox-quantum-beta-developer-edition/ As for the missing bookmark star, what you could try : Click on the 3-bar menu (Firefox menu - 3 horizontal lines in the upper right corner) and at the bottom click on 'Customize'. If you see the bookmark icons there, you can drag and drop them where you want them to be. If that doesn't work : click on 'Restore Defaults'. See : https://support.mozilla.org/en-US/kb/customize-firefox-controls-buttons-and-toolbars And this might come in handy : Press Ctrl + D will let you bookmark ......
