Kee 2.0 is currently undergoing beta testing.
You can download the beta version from https://addons.mozilla.org/en-GB/firefox/addon/keefox/versions/220.127.116.11b2
The Google Chrome beta can be accessed at https://chrome.google.com/webstore/detail/kee/mmhlniccooihdimnnjhamobppdhaolme?hl=en
Some people are experiencing a stability problem with Firefox when Kee is installed. We have yet to identify what causes this, whether it is under the control of Kee or whether Mozilla will need to fix a bug in Firefox before Kee can function reliably. We hope that we can learn more as a result of having people use the add-on in Google Chrome too.
We have only a couple of weeks left before we must force all KeeFox users to upgrade to this version regardless of whether the add-on is as stable as we would like.
With that in mind, we are encouraging all Beta testers to upgrade to a beta version which is likely to suffer from this intermittent problem.
We do not know how prevalent the problem is, nor what causes it to affect some users but not others.
Since it does not affect luckyrat (the main Kee developer) it is not possible to progress any work on a fix unless someone else with development/debugging expertise can contribute to the issue.
If you come across the problem where Firefox freezes as described in https://github.com/kee-org/browser-addon/issues/27 please contribute to the resolution of the issue in any way you can so that we can try to eliminate it entirely before all KeeFox users are upgraded in a week or two.
