I guess https://trac.torproject.org/projects/tor/ticket/20981 is a good
candidate for explaining this.

Thanks Georg. That sounds like it. Was "ToLocaleString" a recent change in Firefox function (or browser standards) that wasn't caught by Tor devs or users before Mozilla implemented it, or some other scenario?

Possibly another example of how dissidents, sympathizers, whistle blowers connecting TBB directly through an ISP (certain countries) could be more easily identified. Very difficult to consistently, quickly keep all leaks patched.

When issues like this are 1st discovered, should there be a better notification system for users, explaining risks and suggested workarounds? Few users have time to read every new Trac report.

Even if they did, many users wouldn't how to avoid risks. Is there any "early warning system" giving *precise* steps to avoid new anonymity threats? Similar to warnings OS & software developers often issue?

AFAICT, Tor bugs are reported, but often no steps recommended to avoid the danger, until patches can be developed. (Temporarily stop using TBB for serious activities?) Does this at times leave some users totally unaware they could be exposed in certain situations?
