Great addon to avoid sending busybody referers Noté 5 sur 5 étoiles

I like that the extension allows you to treat subdomains as different domains, and configure how the referer should be set (same that URL or direct hit).

Great but Noté 4 sur 5 étoiles

Great addon, but is it e10s compatible? Are you working on that? I hope I can keep using this with e10s.

I'm not exactly sure if it is or not, but I have a feeling it is.

In case it isn't I'll fix it tho since I use my own addon :P

Perfect Noté 5 sur 5 étoiles

I was using RefControl before but this one is better (more simple and just looks better). Plus this one works on Firefox Mobile unlike RefControl.

Works wonderfully for privacy. Noté 3 sur 5 étoiles

Not sure why everything online wants to spy on you nowadays...

Thanks developer.

Stops login to FlickR Noté 3 sur 5 étoiles

FlickR recently started preventing me logging in. Disabling Smart Referer resolved the issue. It's a shame, as it's been a reassuring add-on, but now unusable for me.

Works flawlessly, but Firefox 28 has (hidden) preferences for this! Noté 4 sur 5 étoiles

Since Firefox 28 there are three new items in about:config:

network.http.referer.XOriginPolicy: 0=always send, 1=send if base domains match, 2=send if hosts match
network.http.referer.spoofSource: false=real referer, true=spoof referer (use target URI as referer)
network.http.referer.trimmingPolicy: 0=send full URI, 1=scheme+host+port+path, 2=scheme+host+port

Referrer processing is done in this order. Thus, setting XOriginPolicy to 2 makes spoofSource and trimmingPolicy useless if going from to, since no referrer would be send anyway due to the XOriginPolicy.

If using the three new I'd suggest to set the old network.http.sendRefererHeader to 2 (default, always send referrer).

Just what I was looking for. The default whitelist is quite helpful too!

To bad... :( Noté 3 sur 5 étoiles

Not available for your platform. FF 25.0.1 (latest), Win8 (64)
This is an essential function and should be widely available. Please make this compatible or point me in the direction of something that is.

It's already available for that platform and version, something's wrong on your side.

A must have extension for privacy. Noté 5 sur 5 étoiles

Firefox should include this addon by default, it's simple and effective!!! Thank you for taking the time to make this! Five stars all the way!

You're very welcome.

It works, but when I make a change to the preferences, it seems that I need to restart the browser before the changes can take effect.

That shouldn't be the case at all, can you give me some ways to reproduce that behaviour?

Good Noté 4 sur 5 étoiles

I need my own local whitelist like in RefControl

You already have a local whitelist, just put them in the Allow field in the addon's preferences page.

Auto downloading of whitelist.txt Noté 5 sur 5 étoiles

The automatic downloading of the whitelist without user intervention is ok for most but not all. Removing the link in the options stops the download. How can the whitelist.txt be an option or manually setup? Where is it stored? Is it deleted when the browser closes, and then needs to get downloaded again? Other than what is mentioned about the whitelist.txt, the addon works as mentioned.

Reply: Ok, thanks!

It's already an option, if you remove the link from the addon's preference page it won't be reinstated unless you write the URL of your whitelist in that box.

It's not stored anywhere, it's just downloaded and set temporarily in the internal state of the addon, it gets downloaded every 24 hours or every time you enable the addon.

amazing! this should be integrated in firefox

Noté 5 sur 5 étoiles

A minimalistic add-on that does what it says on the tin. Excellent. My only suggestion would be to include an auto-updating rulelist to auto-whitelist major websites that, inevitably, have resulted (and will continue to result) in negative reviews here on AMO. It's important to have a custom whitelist field for fringe cases, but end-users really shouldn't have to whitelist things like and on their own.

That does sound like a good idea, I'll think about how to approach it.

Thanks for the positive review.

Has problems Noté 3 sur 5 étoiles

I've always said that security and privacy are a good thing... up until it interferes with your own access to content.

3 stars for effort. The addon is a good idea in theory.

This addon interferes with viewing content that is served from third-party hosting servers--both enterprise level, and discount alike), such as image hosting, flash media, and video streaming server hosting companies, to name a few, that won't serve the content without a receiving a referrer url from the site that is paying for the hosting to support their portal. This is typically to keep down bandwidth increases resulting from link proliferation due to other services (such as Google Search, for instance.)

This add-on interferes with a lot of sites on the web.If you are multimedia oriented, and spend much of your time looking at video, image sites (like, or listening to streaming music, then this add-on is not for you.

If you spend most of your time scanning news websites, reading articles, writing blogs, and doing research, then this add-on is probably a good idea for you, especially if your involved in controversy like 9/11 Truth, research into US banking and Wall Street frauds, and any other type of conspiracy or government cover-up studies.

* Update: The developer brings up a good point... the addon apparently allows you to "white-list" sites. I didn't check for that. :)

Cette critique concerne une version précédente du module ( 

As any other privacy addon you have to whitelist what you want to happen, and you can do that with this addon too.

It's like saying NoScript and RequestPolicy are bad because they break websites out of the box, you have to configure them, this is true for Smart Referer too.

Prevents videos from playing Noté 4 sur 5 étoiles

I was wondering why a lot of video sites were giving me "video not found" or notices that I needed to visit the video site to play the video (even though I was already there). After I disabled this add-on I was able to view videos on those sites without any problems. Perhaps a whitelist function might be needed in future releases? It was only after I posted this initial review that I found out there were instruction s on preventing this problem on the add-ons home page.

Yeah, it's on the preferences page of the addon in the addon manager.

Essential privacy tool Noté 5 sur 5 étoiles

After blocking tracking URLs and cookies, controlling information leakage through Referer headers is another important privacy measure. And this extension makes it pretty much install-and-forget!

Just works Noté 5 sur 5 étoiles

Coming here from the "change referer button" add-on, and breathing a sigh of relief. Now I can have a whitelist so disqus actually works. And I can use my own referer, which is handy. The "dumb referer" used by Change Referer Button was causing websites to not load properly, unless turn off referer spoofing, which renders the tool useless.

A nice addon just got better Noté 5 sur 5 étoiles

Review Update: my only complaint against this addon was that it didn't offer a GUI, but since this has changed with version 0.0.8*, I have nothing to complain about thus far.

Very nice addon, keep it up. :)

*) For other users: The new version is still marked as experimental until it gets reviewed by Mozilla but can be had from "complete version history" link at the bottom of the page, if anyone is interested.

[scraped]A simple/minimal GUI for...but nice addon nevertheless.[/scraped]

Cette critique concerne une version précédente du module ( 

I added an interface to change the settings, you'll find it in the preferences page in the addon manager.

Although this means bumping the minimum version to Firefox 7.0.

If you could bump the stars or add anything else you don't like after the new version is reviewed it would be nice.
