Excellent add-on that remembers the original URL of pinned tabs. Two options to update pinned tabs via a context menu, and to synchronize tabs and settings across devices make pinning tabs genuinely useful.

It would be nice if it had an option to update the pinned tabs list automatically when you add or remove a pinned tab.

An addon I depend on daily. The only feature request I might hope for is the ability to choose which tabs open on which days of the week.

It does what it does pretty well. It helps me when I run into a case where Firefox loses all of my pinned tabs when it crashes or has session state storage problems. But the biggest issue is that it (1) has no way to import/export the list because sometimes the addon itself loses all of its pins (!!) when the FF storage gets messed up, and (2) the editor interface is clunky and very basic which wouldn't be a big deal if I could import/export from a text file. So much potential, but it needs just a few key features to be the reliability tool we need :)

Exactly what I needed. Thanks.
If you add the ability to create & choose different groups of persistent pinned tabs, your extension (together with Pin Unpin All) could double up as a very reliable session manager – something which Firefox sorely lacks

Work as a charm. Sometimes I close my main Firefox window with pinned tabs if I have another window Firefox would reopen only the latest closed window without my pinned tabs. With the extension, the first Firefox window opened will load the pinned tab as I wished.

Works just fine, you just need to save the pins through the addon menu.

Can't seem to be able to edit the saved addresses however, need to add new ones and replace them manually for the old ones.

huh? It totally removed all my tabs and won't let me re-add them. Removing!

Works flawlessly, and is something I install instantly

Does what it is supposed to do. Nothing more, nothing less.

Works as advertised and was just what I was looking for!

1. when open a new window, it is not pinned
2. restart firefox and there will be two pinned tab, restart again and there will be three and so on

besides the two problem, everything is fine

Allows you to choose persistently pinned tabs while still clearing history on exit, which is exactly what I wanted. These tabs do load on launch, however, and if somehow they could be lazily loaded so as not to slow Firefox's launch when they will not be immediately used, that would be an appreciated feature.
