I'm doing a clean up and restoration of my current windows. Its great that now firefox has sync which makes transferring easier. Base on the article https://support.mozilla.org/en-US/kb/view-synced-tabs-other-devices "Additionally, you can use the Firefox Sidebar to access synced tabs. While viewing synced tabs in Sidebar, right clicking on device name allows you to open all tabs from a device at once. " I've tried and search everywhere but I don't see this option at all. There is no option even after right clicking. At the same time, i'm wondering if sync is better than copying the entire profile over
