Recent Tab List for Safari
Apple has completely discontinued support
for "legacy" .safariextz extensions in macOS Catalina.
(It was deprecated but still functional in Mojave and High Sierra.)
A complete rewrite is needed to make it compatible with Catalina and Safari 13.
I've chosen to stop supporting this extension. The final version (1.7) is still available here
, and the source is here
. Recent versions of Safari have some similar features (for example, a list of recently closed tabs in the History menu).
Please feel free to steal any ideas from this extension if you'd like to make your own.
A Safari extension that keeps track of recently closed tabs and allows you to reopen them quickly. Will also (optionally) display currently open tabs. With a live text filter for easy searching.
