A few hours ago, Apple launched the new version of the Safari browser for Macs, in this case version 13. This update must appear automatically on your computer as soon as you open it, otherwise you can access it directly from System Preferences> updates.
The truth is that not everyone works well with this new version of the Apple browser on their Mac and this is something that is surprising considering that the company tests every two weeks with the experimental browser Safari Technology Preview, anyway It is something specific that does not happen to everyone.
Some extensions have stopped working at the moment
This new version also affects some of the extensions that we had installed on the computer and that is that Apple in the new version of Safari prioritizes security and it seems that some of them could affect this important section of our Mac, and they have already warned that some of these extensions would stop working in macOS Catalina.
The truth is that in my case I had some extensions that now do not work, these are: Gosthery and the well-known Amazon extension camelcamelcamel. Can you live peacefully without them? Well, clearly yes, but it is evident that this elimination of the extensions is a part of Safari and many of the users of these extensions have to know this information before updating. If your extension is not available in the extensions section of the Mac App Store, keep in mind that you will not be able to install it.
