(In reply to Valentina Claudia Ona from comment #0) > [Actual result]: -The search icon is on the right side(on Ubuntu and > Windows) Yeah, that's buggy because the synced tabs sidebar is implemented in HTML and a big mess. :( > -The text from the search field is "Search synced tabs" (on Ubuntu and > Windows) Not sure if this was actually supposed to change or just an arbitrary difference in the mockup. > -The search box has square corners(on Windows) As far as I remember, Stephen said the native textbox styling is fine here. Reducing the scope of this bug to the first issue so that it's actionable.

You can check by setting intl.uidirection to 1 in about:config.
