In the latest version of Safari Apple has discontinued support for extensions in favor of a new extension format. If you currently use the Safari extension you will see the following message when you first open your browser after updating to Safari version 13:
Apple’s new format no longer allows standalone extensions. Instead, you must first download an App and the App can install the extension. TinEye does not currently have a Mac App, but we are looking in to developing one in the near future.
In the meantime, we suggest you consider using Firefox as an alternative. The TinEye extension is an official Firefox recommended extension, which means that it has been recognized as meeting “the highest standards of security, functionality, and user experience.” We also offer a TinEye extension for Chrome. We hope you’ll give one of them a try until our App release. Who knows? You may never be go back to Safari! :)
Happy searching!
