Pocket is a web-based service for creating lists of URLs and sharing them between devices you use, even those devices do not use Firefox. If that doesn't sound useful, you can right-click the icon and choose "Remove from Toolbar" to remove it. (This also removes it from the Bookmarks menu.)

More information:

• Save web pages for later with Pocket for Firefox
• Disable or re-enable Pocket for Firefox

What is the difference between "Pocket" and Bookmarks+Sync ? I do not understand what "web-based" means.

Bookmarks seems to add every website I visit to its list, regardless of whether I want to save it or not. Does Pocket do this too?

I think you may be confusing "History" with "Bookmarks".

History keeps a record of sites you've visited with no input needed from you. I sometimes find that very useful for finding sites that I've visited.

Bookmarks require you to take action to bookmark sites.

So does Pocket.

I think Pocket is also a way to share those urls with others.
