This doesn't always happen, but its annoying when it does. It also only happens if I have the first tab in the list selected, and seems to not happen if all the tabs have the same favicon. Reproducible: Sometimes Steps to Reproduce: 1. Open Google as the first tab in a new browser 2. Perform a Google Search 3. Begin opening results (you can use just one or different links) in tabs until close buttons disappear Actual Results: When the tab bar is just full enough that close buttons are removed, tab bar begins to go crazy. Expected Results: The close tab buttons should disappear and the tab bar should remain stable.

fixed width tabs will be turned on once tab overflow is implemented.
