User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:56.0) Gecko/20100101 Firefox/56.0 Build ID: 20170705100303 Steps to reproduce: Prob A) Dragging a URL from address bar into bookmarks will assign a 'favicon' icon based on previous drag into bookmarks. To reproduce, create a simple favicon-free html page e.g. <!DOCTYPE html> <html> <body> <h1>My First Heading</h1> <p>My first paragraph.</p> </body> </html> Open page this simple page into a tab. In another tab, open some other page (e.g. I used duckduckgo.com) Drag the 'other page' - click-drag the "i" icon in the address bar - down into the shortcuts bar and release it there. Now change to the simple-page tab, and drag it into the shortcut bar. The icon assigned to simple-page is the icon of the 'other-page'. Other problem (related?) Problem B) Wrong title on Tab after the event of 'A' above (May have to close the simple-page tab and re-open it?) The simple-page's tab has a Title of the "other page" (in my test case DuckDuckGo) Problem C) Doing an embedded base64 encoded favicon doesn't seem to be working in nightly. ie using form: <link rel="icon" type="image/x-icon" href="data:image/x-icon;base64,AAA.....characters....==" > placed in the <Head> section does not seem to be picked up by Nightly, yet works in Safari browser. Actual results: As above A) wrong icon assigned to bookmark B) wrong title on tab C) no favicon picked up from an embedded data <link> tag.
