Works perfectly, I never found a problem with it and it helped me uncover some deleted pdf files.

Have been using this since it was a Firefox Test Pilot project called "No More 404s". Never had any problems with it. It's one of those features that should be built into Firefox.

So useful add-on.

But there is a problem with the context menu: When you right click on a link and select an option (like First Version) it shows the current site that you are visiting (the URL at your address bar) instead of the URL you clicked on.

I don't know if it's a bug or a feature but It would be very useful if it opens the link you right clicked upon :/

Also there is a bug unique to Firefox; if URL is not found, nothing happens. In Chrome it warns with a pop-up message.

Thank you for this add-on and glorious Archive.org itself <3

Works perfectly.

Extremely useful. The new update is great

The Internet's backup.

Truly useful.

Works well for me. Thank you. (I use it alot because I work with the Internet Archive)

Полезняшка!

I love this extension for referencing information I have seen in the past that may not be present in search bars. Thank you for this addon!

Which is quite a bit less than it would take you to do the same on the official site. It's a winner :)
