I use this all the time. How is e10 compatibility coming along?

Great addon to avoid sending busybody referers Bewertet mit 5 von 5 Sternen

I like the fact the extension allows you to treat subdomains as different domains, and to configure how the referer should be set (same than URL or direct hit). The project is on GitHub:

Great but Bewertet mit 4 von 5 Sternen

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

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. Bewertet mit 3 von 5 Sternen

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

Stops login to FlickR Bewertet mit 3 von 5 Sternen

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! Bewertet mit 4 von 5 Sternen

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... :( Bewertet mit 3 von 5 Sternen

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. Bewertet mit 5 von 5 Sternen

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 Bewertet mit 4 von 5 Sternen

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 Bewertet mit 5 von 5 Sternen

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.

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 Bewertet mit 3 von 5 Sternen

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. :)

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 Bewertet mit 4 von 5 Sternen

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 Bewertet mit 5 von 5 Sternen

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!
