• (2020-07-01) Sylvain: This seems to work @ 300ms on Keytrack but they were able to get high confidence @ 200ms for me. The Experimental port on Mozilla Addons does not work at all for me however, any chance you can finally port this to Firefox, now that they have a decent WebExtension API?
• (2018-06-12) It's great stuff, super interesting.
• (2017-11-20) mytransceiver: No, as of 2017 Nov, all the "biometric" can over come this tiny trick with over 90% confidence. Even 1000 dwell/delay would not help at all.
• (2017-05-25) Franco GR: I've been using this extension for quite a while, both in Firefox and Chrome. It's great.
• (2016-07-30) Puppette Master: With the add-on disabled, converged on a green policy for the id; during testing of the trained id, needed to set add-on to 500 each dwell/delay to confuse the tested id to red reliably. Full training with the add-on enabled at 500 dwell/delay each still converged on a green id policy; also, it still recognized the id during testing with or without the add-on enabled at 500. Full training with add-on at 1000 each converged on a red policy during training, yellow policy during testing, yellow or red identification; during testing, did not matter with or without add-on Unfortunately it seems the only thing that confuses the app is the add-on slowing down my slow connection/processor so much that it cannot get any timing data off the keyboard at all due to the latencies.
• (2016-06-07) David McCarty: Man, I must be really easy to profile because I turned my settings up to 5000 for both gap and dwell and I am still consistently getting >97%. Actually, I'm not really sure if the plugin is actually doing anything because I don't notice any kind of delay, even with these really high settings. Of course, if I consciously make myself type in an unusual fashion, I get < 10%, but then it's not the plugin, it's me. On the plus side, the plug-in doesn't seem to be causing any determent to my online experience, so I don't want to be too harsh with my rating. I love the idea...
• (2016-05-04) Andre S.: i like dit. tx
• (2016-02-06) Zaki Manian: Would be much better with a url whitelist
• (2015-10-28) J Locky: Works like a charm also directly hits the page in way boosting my paging speed
• (2015-09-28) Andrés Aguilar: me parece una exclente extención, pero si saben darle un buen uso :)
• (2015-08-20) Roul Terra: Worthy add-on towards ensuring a bit more anonymity in the world of billions of personal data points!
• (2015-08-05) Dwell and gap times should be random for each keystroke
• (2015-07-30) Woo Hoo: Works, however, the dwell and gap times should be random for each website instance
• (2015-07-29) Mark Hansen: As the three one-star reviews note, yes, it does seem a bit wonky with the default settings. I upped mine to 100 dwell, 120 gap, and consistently get <50% accuracy on that site now. It works great; the default settings are just a bit too much within normal variation.
• (2015-07-29) David Lopes: It seems that if you thinker with the global settings you get a lower %
• (2015-07-28) Per Thorsheim: Works just as intended! :-)

• (2022-08-31, v:2.7) Clint Earl: Privacy policy
  There is no description of your privacy policy, and the use or collection of data. I'm hoping that there is no collection of any user data however it would be nice to confirm that.
• (2022-01-31, v:2.7) David A: Add-on for Firefox
  I have installed this extension on Chrome and Edge but as I use Firefox more frequently I searched for it but could not find it. Does it have a different name for Firefox or does it not exists for Firefox? Thanks.
• (2017-08-17, v:2.5) James Page: Super-slow keyboard performance
  I've noticed the extension has had an impact on usability in recent editions of Chrome - sites like Gmail, Twitter and a few others using form fields have latency of up to a few seconds when entering text.
• (2017-05-31, v:2.5) Gil Huerta: Inactive in Gmail.com
  It really slows down my browser. Why does this app always go inactive on GMAIL? I'm more interested in additional privacy for my typed messages than my browsing history. Is this Google's doing that blocks the keyboard privacy?
• (2015-09-30, v:2.4) Tim DuBois: Lag on pages with textareas
  I've noticed that pages with text boxes on them tend to lag terribly to the point of non-usability when I this enabled. Examples: Facebook messages, google translate and maps. My settings are at 100/120 at the moment. Is there any form of troubleshooting you recommend for this?
• (2015-07-29, v:2.4) Vidya Wasi: Firefox support
  Please add support for Firefox. Open source software needs your help with security.
• (2015-07-29, v:2.4) TWOK: Dwell/Gap Times
  Per the reviews, I tested the keytrac site with the default settings and got 88% accuracy. Set it to 100 for both dwell and gap and it went down to 55%. You may wish to consider altering the defaults to at least 100 because 88% is too high for comfort. Keep up the good work!
