842671 - Pinned App tabs shift off the screen

Status: RESOLVED DUPLICATE of bug 837486

(Firefox :: Tabbed Browser, defect)

Attachment: Screenshot of this happening

I don't have exact STR, but every now and then Firefox seems to shift my pinned app tabs outside the Firefox window. This is a recent regression, say 1-3 weeks ago. See screenshot.

Potentially related to bug 837486.

It seems to happen when the tab bar goes from the state where there are more tabs than that fit in the width of the Firefox window, to the state where they do fit if they are resized, by closing some tabs on the leftmost of the tabs row. But not always, so no hard STR.
