UXP is an actively maintained fork with a historical fork point of the Mozilla code at Firefox 52 ESR with significant modifications to be a codebase for updated web technology support and creating any number of XUL-based applications. To demonstrate, develop and refine the platform, Straver used it to create a new browser, Basilisk. Pale Moon 28, released in August 2018, was the first version built on UXP, thereby providing improved support for web standards and video. Pale Moon for Android was a distinct development effort that is no longer maintained. First released in 2014, Straver announced the following year that it would likely be abandoned due to lack of community involvement. The final release was 25.9.6. , Straver has remarked that the role of benchmark tests is questionable, stating that they "can't be used to draw hard (or regularly even any) conclusions. Plain and simple: they are an indication, nothing more. They serve well if you compare closely related siblings (e.g. Firefox and Iceweasel) or different builds of the exact same browser, to get a relative performance difference between the two on the limited subset of what is actually tested, but that's about as far as it goes." The questionable role of benchmarking was confirmed by leading technology experts when, for example, Google announced it was retiring its Octane benchmark in 2017. In 2013, Pale Moon was a bit slower than Firefox in the ClubCompy Real-World Benchmark, with the browsers respectively scoring 8,168 and 9,344 points out of a possible 50,000. In a 2016 browser comparison test by Ghacks, Pale Moon version 25 had the smallest memory footprint after opening 10 different websites in separate tabs. However, in the same report Pale Moon scored bottom in the Mozilla Kraken, Google Octane, 32-bit RoboHornet tests and second-to-last in the 64-bit RoboHornet benchmarks. Whilst other browsers hung during some tests, Pale Moon only hung during the JetStream JavaScript benchmark. Current (UXP) versions of Pale Moon score comparatively to other browsers in benchmarks, showing, for example, no significant difference on the Sunspider benchmark compared to Firefox Quantum. Worldwide market share according to StatCounter was stable at 0.02% between March 2019 and 2020. It was reported on 10 July 2019 that a data breach of the archive server holding previous binaries of the Pale Moon browser had occurred and malware inserted into the executables. This breach was discovered on the previous day.
