I no longer trust cloned browsers, and the issue of delayed security updates must first be resolved. I'm not talking about a delay of a day or two, as is the case with Brave and Vivaldi browsers, which is acceptable, but at least a whole week. I was a happy user of the Waterfox browser until I discovered that it had not yet been updated to the latest version of Firefox ESR, even though it was a critical security update.
Thanks to
@Marko :) for telling me this earlier, and now I'm back to using Firefox again.
