Mozilla/5.0 (Windows NT 10.0; rv:55.0) Gecko/20100101 Firefox/55.0 Build ID: 20170426030329 [Affected versions]: - Nightly 55.0a1 [Affected platforms]: - All [Steps to reproduce]: 1. Launch Firefox 2. Write something in the Search Bar 3. Press Down key to reach to the first one-off button 4. Press Righ/Left key until the first add-on is selected again [Expected result]: - Left and Right keys should cycle through the one-offs including the Change Search Settings button.(at least this is the behavior in the one-off bar in the Awesome bar) [Actual result]: - Change Search Settings button is not included in the navigation cycle when Left and Right keys are used.

I think this is intended. In the awesomebar the behavior is different because the settings button is on the same line as the one-off buttons.

Thanks Florian. Drew do you concur that this is a wontfix or do we need to ask shorlander?

Yes, that's the intended behavior. In the urlbar, the settings button is treated like a search button in this case (presumably since it's basically the same size and on the same line). In the search bar, it's treated as a separate kind of button. I'll mark this wontfix, but thanks for filing this, Simona.
