I use a bookmarks toolbar located to the right of the "main menu" items (File, Edit, View etc.) with all of the names blank, so that only favicons are shown. First of all, it would be nice if the bookmarks bar stretched all the way from the end of the p in "Help" to the right of the browser, as would be expected. Not only does it not do this, but whenever I start Firefox, I have to hide the bookmarks bar and then unhide it in order for all of my favicons to be shown without being truncated by a chevron. For the rest of the browsing session all of them are shown.

Reproducible: Always

Steps to Reproduce:
1. Add 36 items to the bookmarks toolbar.
2. Use each bookmark on the toolbar to load the favicon.
3. Make the name of each bookmark blank.
4. Move the bookmarks toolbar to the right of the "main menu" items
5. Notice how the toolbar is unnecessarily truncated unless hidden and re-shown.
Actual Results:  
The toolbar is cut off even though there is plenty of space in the UI.

Expected Results:  
Allow favicon-only bookmarks to fill the entire space.

Default theme, no UI related extensions active.
