Webextensions have nothing to do with element sizing in the firefox ui.  Sizing per-window like this I believe is intentional, but I'll let someone on Firefox verify that.

We do persist the side of the sidebar, so I don't think it's meant to be 'fully' per-window. Unfortunately we only persist the size when the window with the sidebar closes, so to fix the steps from comment #0 we'd probably want to also store it when the sidebar (but not its window) closes.
