Blocks common browser fingerprint techniques to improve your privacy.
RubberGlove aims to reduce the ability of websites to globally fingerprint your browser. The Electronic Frontier Foundation's website, panopticlick.eff.org, and the associated study shows just how effective these techniques are for tracking you even without cookies.
Currently it wraps the window.navigator and window.clientInformation objects to cloak plugins and mime types similar to the way it's done in Firefox and IE.
Planned future features:
* Ability to add exceptions for specified sites (very soon)
* Reduction of detailed version information both in window.navigator and the http User-Agent header.
* Prevention of time skew and drift fingerprinting
* Prevention of canvas based fingerprinting
Please note that until this plugin or others like it are widely used, Panopticlick will likely still report your browser as unique despite the significant reduction in bits of identifying information.

- The author seems to be absent from the internet: no response on github, last activity on superuser.com summer 2016, no other web results for his name. The critical missing feature that someone needs to fork and implement is the whitelisting. This is the repository https://github.com/jsclary/RubberGlove

- Rolling out a whitelist (vs. having to manually disable it whenever I want to use a site it breaks) should be a priority. As of this writing the feature will be available "very soon" - it's been that way for a while, and it needs it like, yesterday. User customization of privacy enhancements - enabling and disabling first, then modifying, then manually adding & suggesting (I understand the latter won't be as easy) should come next. These features would make this tool a real winner among users concerned with privacy and in the privacy community. I would be very likely to endorse it at that point. RubberGlove is off to a good start. Some tweaks and mid-to-long term planning for changes could make it great.

- This made a huge difference on how Panopticlick read my fingerprint. It does kick me back to the old gmail interface but frankly I get tired of the wait while that loads. It also kills youtube from what I can gather so yeah a whitelist would be a good next step. It also kills my RSS reader and I tried 2 others and the same results. I find it also kills disqus commenting and probably livefyre as well.

- badly needs a whitelist

- Installed because of getting rid of my very specific font list delivered by Javascript. Turning this off is not an option. The extension changes nothing as far as I can see. no improvement.

- The Panopticlick fingerprinting test page reports almost the same identification level with or without the extension. The useragent got even more bits (14.9) than before (12). The extension list is still available, so is the font list. Don't know how this is preventing anything.

- Works for the most part but prevent some of my websites from working with no option to whitelist the sites.
- Nacho Garcia
- Funciona perfectamente.
