Take a look at these links. https://support.mozilla.org/en-US/kb/how-do-i-set-sync-my-computer https://support.mozilla.org/en-US/kb/how-do-i-choose-what-information-sync-firefox

The screenshot is of my synced devices. This way my data is backed up on different devices. If something happens to 1 browser I can send it from another.

Thanks for replying. I deleted Firefox as a dry run. Tried what the links suggested and seem to have lost the bookmarks unless I click on bookmarks in options top right (Three horizontal bars). I have also lost another button which was on the top toolbar which was about 50% of other bookmarks. Looked like an Envelope as I recall and used to be about an Inch in from the right, next to the pocket button. Sorry, struggling :(.

I'm confused... You say it's resolved, but is it??? ;-)

Misclick or Mistake. We all make them. On topic, when I click the options top right I get a "Shrunken" list of Bookmarks. Still only showing half what was available. I Click on manage bookmarks Ctrl+Shift+O gives me the other ist of bookmarks after clicking around the other small options top of the other list. Not really making sense am I? Trying my best.
