Quo Vadis? Firefox

Quo Vadis?

By: basa Add-on
Quo Vadis ends the lack of transparency of shortened URLs, by revealing every link in the chain of URL redirections.

Features & Capabilities

When you click a shortened URL, like https://bit.ly/3yuZeRo, do you know where it leads? Probably not. Don't you wish you could tell where a URL leads? All URL redirections, including URL shortening, should be transparent. That is the mission of "Quo Vadis?", which is Latin for "Where are you going?".

Quo Vadis is a web extension that ends the lack of transparency of shortened URLs, by revealing every link in the chain of URL redirections. It allows you to decide whether you actually want to visit the unshortened URL.

First download and install the extension in your web browser. Now, whenever you see a URL that looks funky, just ignore it and move on to something else 🙄. When you still want to know where the link leads, without opening it in your browser, right click the link and select "Quo Vadis?" from the context menu options. Quo Vadis probes the URL you selected. The URL may redirect to a second URL. The second URL may redirect to a third URL. And so on. Quo Vadis follows and displays the complete route of linked 'affiliated' URLs. These are mostly trackers, gathering your data for advertisers in a split second, unseen by you. This route ultimately leads to a URL that is not redirected: the final URL. Seeing the final URL, you can make an informed decision about whether you want to open it, or avoid it.

Each encountered URL is colored:

  • Black: Currently being probed.
  • Gray: Redirects to another URL (probed next).
  • Red: Redirects to an already encountered URL.
  • Orange: Returned an error.
  • Green: Final URL, no errors, no redirections.
Quo Vadis requires no configuration. Check out https://basa.nl/quovadis/ for more details, and some interesting examples of Quo Vadis results.

User Reviews

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.

Is Quo Vadis? Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Quo Vadis? requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ****** *** ********* ** ******* *** ******* ******* ** ****** *** *** ******** ******
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Quo Vadis? has earned a fairly good reputation and likely can be trusted.
