Users on Safari 12 / Safari 13 and later, see the list of new Safari App Extensions.

Apple have announced that "the [Legacy] Safari Extensions Gallery will no longer be available in September 2019. Legacy Safari Extensions (.safariextz files) are not supported in Safari 13 on macOS Catalina, macOS Mojave, or macOS High Sierra. Users on macOS High Sierra or later [should] find extensions on the Mac App Store by choosing Safari Extensions from the Safari menu."

Unfortunately, due to these changes, legacy extensions can no longer receive updates.

The following extensions have been rewritten for Safari 12 / Safari 13 & later and continue to receive updates: BackTrack, CustomSearch, FullPath, HoverSee, ReMap, TranslateMe
