Created attachment 8696477 [details] Gif showing the issue Affected builds: - latest Aurora 44.0a2 - latest Nightly 45.0a1 Affected OS`s: - Windows 10 64-bit - Ubuntu 14.04 32-bit - Mac OS X 10.10 (string needs to be displayed on four rows) STR: 1. Start Firefox 2. Start a conversation 3. Resize the width of Firefox until the string is displayed on three rows Expected results:. IMHO I think the string should be allowed to be displayed only on two rows or one, and the missing string should be hidden by three dots. Actual results: A black line is displayed. Notes: - This is not a regression, it was introduced when the Share bar was added, bug 1214214.
