Tweaks uses local extension storage for your Tweaks preferences. I've found that in some cases, Safari not only forgets the extensions, it also erases the extension storage! Extension storage files are located inside the folder ~/Library/Containers//Data/Library/Safari/WebExtensions/ on your Mac. However, this command might not restore your extension data.
The problem has plagued all of us for more than a year, and Apple seems to refuse to make it a priority.Īs a reminder, if your Safari web extensions have disappeared, you can restore them with a command in Terminal: /System/Library/Frameworks/amework/Frameworks/amework/Support/lsregister -f -R /Applications/Safari.app And it continues to happen to other Safari users, not just users of my Safari web extension Tweaks for Twitter, but to users of all Safari web extensions from every developer. It's happening to me rather frequently now. The bug seems to have started on Big Sur, and unfortunately it hasn't gotten any better on Monterey.
