FTP support already removed from Nightly and Beta builds
Mozilla has just announced that it’s planning on giving up on FTP support in Firefox browser, with version 90 to be the one removing the feature completely. In the meantime, Mozilla plans to just disable FTP in the browser, and the upcoming Firefox 88, which is due to ship on April 19, will no longer allow FTP connections. At the same time, FTP support has also been disabled in the current beta and nightly builds of the browser. Plans to remove FTP in Firefox were officially announced back in April 2020, and at that point, the team working on the browser explained that few people were still using it, so keeping this feature around made little sense.
