Hi noel.hilleret, To save your tabs so that they will automatically reopen every time you use Firefox, you will want to pin your tabs. To do this "right-click on the tab you want to pin and select Pin Tab from the menu." This article and video contains further instructions: [[Pinned Tabs - keep favorite websites open and just a click away]] If you would prefer not to have your tabs automatically reopen every time you use Firefox but to still save these tabs, then you will want to bookmark the tabs. You can organize them in a single folder for easy access by doing the following (discussed in [https://support.mozilla.org/en-US/kb/tabs-organize-websites-single-window this article]): "Select the tabs you want (Ctrl-click on each tab), then right-click on one of them and select Bookmark Tab.... A new folder will be created to contain bookmarks for each tab. Give the new bookmarks folder a name and choose which folder to store it in. Click Save to finish."
