| Implement incremental cycle collection to reduce<sup>1</sup> cycle collector pauses in the Firefox UI.
<sup>1</sup><span style="font-size: 80%;">Reduction in cycle collector pauses will be measured with the [http://mzl.la/XLsAoB CYCLE_COLLECTOR_FULL Telemetry probe]. The degree of reduction that can be achieved is currently unclear.</span>
