What are the Spectre and Meltdown issues related to FF52esr?

  • 772

As far as I have read, including USN-3516-1: Firefox vulnerabilities, only FF57 (in 57.0.4) is being updated due to these issues.

As some people are using FF52esr (currently 52.5.3), is there any downside or different plan for these users? I haven't seen any updates for these issues.

  1. SharedArrayBuffer is disabled by default on Firefox 52 ESR.

    Firefox ESR 52.6.0 has been released. From blog post on Mozilla:

    performance.now() mitigations will be included in the regularly scheduled Firefox 52.6 ESR release on January 23, 2018.
