"Bookmark All Tabs" is not located in the Bookmarks menu.

If you would like "Bookmark All Tabs" to be visible in the bookmark menu, then you need to contact the developer of the add-on you installed to move the menu item or to allow user to choose a location.

Note: You can RIGHT CLICK any TAB and the "Bookmark All Tabs" is possible. That is built into Firefox.

...I downloaded the add-on from the firefox website so they would be the developer...?

I did not know that about right click thanks.

Add-ons are Developed by 3rd party developers; ie not Firefox. The Developers name is listed below the Title of the add-on.

Be sure to make your Support Question as solved if it was answered.

Some menu entries in the main menu bar are hidden if you use the mouse and only appear if you use the keyboard to open the menu (Bug 626825).

You can see the difference if you use Alt+F to open the File menu or other menus like the Edit menu (Alt+E) and Bookmarks menu (Alt+B) and compare that to what you see if you use the mouse to open the menu after you have made the menu bar visible by tapping Alt or by pressing F10.

• "Bookmark All Tabs" (Shift+Ctrl+D) no longer shows in the Bookmarks menu unless you open the Bookmarks menu via the keyboard (Alt + B).
• "Bookmark All Tabs" can be accessed via the right-click context menu of a tab on the tab bar.

I did not know that core-el. I just tried it and I see it on there now. How strange it is like that!

iMarshmellow, I think I should uninstall the add-on then? because I don't know the developer and you both have told me a different way to get the feature I want. Can you tell me how to go about uninstalling it?

Detailed instruction on how to Uninstall an Add-on can be found here:

• Uninstalling Add-ons

"remove" is the same as uninstall?

Yes, if you click the Remove button on the about:addons page then you uninstall the extension.

thank you both
