Duplicate Bookmarks

To get rid of all these folders, select one, press Command on the keyboard, and select the rest of the folders you want to delete. Then double click on one of the folders, and press Delete. If you are just trying to delete bookmarks, you don't need to export them. In Safari, press the Bookmarks tab on the very top of the screen. Then press Edit Bookmarks. In this page, you can both delete folders and bookmarks by simply double clicking and pressing Delete.

Since the Favorites folder is a subset of all the folders above it, it will be deleted if you delete any of the higher up folders. As a result, first copy and paste all your bookmarks into the folder you want to keep, and then delete the folders you don't want. For example, you can paste them into the folder "Imported 5/6/2021", rename it "Favorites", and delete the rest of the folders.

Yes, do this in Safari. You don't need to do this in Finder. If you want to get rid of folders or delete bookmarks, you can do it in Safari (by going to Bookmarks on the top of the screen, pressing Edit Bookmarks, and double clicking on what you want to delete). Let me know if that's what you mean.

If you are trying to delete bookmarks and folders, you should be able to do that in Safari. Is that what you would like to do? The plist file can be edited using Xcode, but this is much more difficult than just Safari.

Xcode can be used to delete bookmarks and folders, but there is a much easier way. Open Safari, and press "Bookmarks" on the very top of the screen (where there's the Apple logo). Then press "Edit Bookmarks". After that, use two fingers on the trackpad or double click the bookmarks or folders you want to delete. When you do that, a menu pops up, and you press "Delete".

As for getting rid of duplicate bookmarks, I think the easiest way was to use an extension, such as through Firefox or Chrome. Xcode is possible, but I'm not sure how that would work. However, I'm not sure why the Firefox one did not work...

Yes, you can sort bookmarks. Open Safari, and press "Bookmarks" on the very top of the screen (the bar with the Apple logo). Then click "Edit Bookmarks". Once that opens, double click or control-click the folder containing the bookmarks you want to arrange (it's usually the Favorites folder). Then press "Sort By". After that, click "Name". The bookmarks should then be sorted.

Yep, there's also a way to do it in Firefox. You want to open up the "Manage Bookmarks" page. After that, double click or control-click the folder containing the bookmarks you want to arrange. Then press "Sort By Name".

There is an article by Mozilla that lists the instructions with more detail: https://support.mozilla.org/en-US/kb/sort-bookmarks-quickly-find-ones-you-want

You're correct that by deleting the imported folders, the bookmarks in the Favorites folder would also be deleted. However, first copy all your bookmarks (which you can do by just coping the Favorites folder). Then paste it before the imported folders. After that, just delete all the imported folders. The bookmarks will be deleted, but you will still have a copy because you pasted it into a folder before the imported folders.

It was a pleasure to help, and I'm glad we were able to sort the issue out! We can't give our emails on Apple Communities because they will take down the post due to personal information, but feel free to ask more questions on the forum. It was nice to meet and talk with you! Enjoy your new mouse.
