So glad to have found this. It's a real timesaver as opposed to using third party sites on additional tabs, to determine the path of redirections. Athough in the interest of transparency* I would still like to know whether the crafter of the shortURL/redirection link is able to receive tracking info at the time the extension runs its query. But using Quo Vadis does exceed expectations otherwise.

*I would not recommend to anyone seeking a high level of privacy to use any extension which collects every URL visited.

Though rarely used, it's great at untangling webs of redirection. I just wish I could control when the option appears (e.g. only show the option on certain domains), but only because I'm trying to trim the number of options in my context menu, a bit of an XY-problem situation.

Really useful tool, can't understand why Firefox doesn't implement something like this by default, beats "copy link without site tracking" option by a mile. At the very least Mozilla should review and promote addons like this one.

Quo Vadis? is the only link-unshortening extension on AMO (that I know of) that does not send your URL to the developer's server or a third-party service for analysis. That makes it significantly faster and more private. It also has a better user interface than the others: Instead of opening an interstitial page with a link for you to click, and/or opening the final URL after checking against a blocklist, Quo Vadis? simply opens a popup in-page that shows you the redirect(s) and lets you decide whether the final URL is something you want to click on. Very well done.

Very insightful.

The last update made this perfect! Click on a FB or any other link and the ultimate URL is shown.

Even better, the link is live and the FB landing page is skipped. Yay!

If you do not have this extension, you are flying blind.
