Firefox: Can I have a visible address bar when the window is narrow?

Question

Sometimes I like to put a browser window on half the screen instead of fullscreen. But then the address bar gets tiny which is very annoying when I want to edit the url. I think it used to overflow the addon buttons into a >> menu the way it does bookmarks, or maybe that's wishful thinking. Is there a way to get it to overflow addons into a menu instead of hiding the URL?

Also, why does it add so much space before the >>, that's ridiculous (and no I did not manually add a spacer there). And there are now three of those site icons for per-domain settings/security/cookies, can't they be collapsed into one? and both the translations addon and and multi-account containers also pollute the url bar</rant>

EDIT: With compact mode on:

Answer 1

Do this (as long as it still works) :

• Go to about:config in the address bar
• If a warning appears, click "Accept the Risk" and Continue
• Type browser.compactmode.show
• Double-click the entry to set it to true
• Restart Firefox
• Click Settings > More tools > Customize toolbar…
• At the bottom click "Density"
• Choose "Compact (not supported)"
• You may also hover over user-interface elements and close them by clicking the X or move them around
• Click "Done" when finished
• You may return to the previous state by selecting Density as Normal.
