Both Firefox and Chrome have been running experiments where current versions of the browser report being at major version 100 in order to detect possible website breakage. This has led to a few reported issues, some of which have already been fixed. These experiments will continue to run until the release of version 100.
There are also backup mitigation strategies in place, in case version 100 release to stable channels causes more damage to websites than anticipated.
