Does What It Says It Will & Does It Well Rated 5 out of 5 stars

I would not use bit.ly or any other URL shortener until Quo Vadis.

Call me old-fashioned, but I've been on the Web since the late 80s and, as another old goes: "Fool me once, shame on you; fool me twice, shame on me."

Quo Vadis hasn't failed me yet. Thank you much to the author.

This user has a previous review of this add-on.

Thank you.

Thanks, but where's the source code? Rated 2 out of 5 stars

Nice addon, useful and with a clean UI. Sadly, it works on some links, but stops on roughly half short URLs.

Apart from that, this add-on is supposedly under the BSD license, implying its source code should be available somewhere. However, I can't find any mention to a source repository neither here nor on the developer's website.

@basa, are you still working on this project, or is it true that "[This add-on is no longer supported by the developer.]", as told in Quo Vadis description ?

- If you are still working on it, I'd be glad to contribute to such an useful tool. But then, where do you host the code ? Where can we contribute to your work ?

- If you did stop working on it, is this project really under BSD license ? The current version of the extension is shipped without any license information, even if BSD license mandates that "Redistributions of source code MUST retain the above copyright notice, this list of conditions and the following disclaimer." Moreover, the file quovadis-logic.js bears a header with the mention "// (c) Copyright 2014 by basa.nl.", which definitely does not look like a free licensed project.

Could you please clarify your position on this matter ?

EDIT: Here are some example of links that are not unshortened:

- https://t.co/MzaDzwFtm0 -> http://po.st/qWzYws (Quo vadis stops here, orange link) -> http://www.frenchweb.fr/5-start-up-francaises-de-liot-qui-vont-seduire-au-ces/221372 (final url)

- https://t.co/poEJoSYlGh -> http://po.st/qWzYws -> trib.al/P2Forxy (Quo vadis stops here, orange link) -> http://www.theguardian.com/commentisfree/2016/jan/08/kardashian-revenge-body?CMP=twt_gu

- http://t.ted.com/OdoRlwx (Quo vadis stops here, orange link) -> http://www.ted.com/talks/gayle_tzemach_lemmon_meet_the_first_women_to_fight_on_the_front_lines_of_an_american_war

- http://bit.ly/1S1JFrb (Quo vadis stops here, orange link) -> https://bitbucket.org/DjebbZ/bistromathique/

And so on. I hope this can help you debugging !

Really?

All final URLs were reached and all final URLs appeared as green text, indicating a HTTP response code 200 OK.
You quoted text from the source code file, so I guess you found it.
I wonder if you are using a the latest release of Quo Vadis?, being 1.4.0.1.
Are you using a release version of Firefox? Which one?
What platform are you using?

Why for referrer uses http://quovadis.basa.nl/?

upd:
@basa Really, why?.. But some strange people specially install addons to change referrer. Why do they do it?! Why does not everyone use your site for that?! Strange...

Why not?

I want to copy some of the intermediate links and
I would like to display another, URLs to be seen all at once.
Sorry for my English.

I've had this request eariler, quite a while back.
I'm thinking about a nice way to do this.

This is exactly the tool I am looking for. Unfortunately does not seem to work (with Google search results). The tracking URLs were presented as-is in the right-click Quo Vadis popup instead of showing the target.

This review is for a previous version of the add-on (1.3.0.1-signed.1-signed). 

Thank you for your review.
Version 1.4.0 fixes the issue with Google (and DuckDuckGo) search results.
