Mozilla has slowed the rollout of Firefox 82 just two days after its release due to printing bugs and crashes in the new version. Firefox 82 was released on October 20th, with only a few improvements in performance and its Picture-in-Picture feature. There are no immediate plans to release a new version yet or information on when Firefox 82’s rollout will continue. A fix for the printing issue is currently being tested in Firefox 83 Beta. There have been numerous bug reports stating that the browser is now printing blank receipts to receipt printers.
