BookMacster

BookMacster is a bookmarks manager for your Mac, which plays nicely Firefox Sync Sign In to Chrome, and Opera Sync. It can be used in three ways, or all three:

• Manage Browser Bookmarks. Add alphabetizing and tagging. Verify, fix dupes, consolidate.
• Cross-Browser Syncing. Sync bookmarks of Firefox, Chrome, Opera and more among all your devices.
• Directly. Keep your bookmarks in one central store, accessible within web browsers.

Features

• Compatible with Firefox Sync, Google Chrome's Sign In. Bookmarks added to these apps on your Mac will show up in these apps on iOS or Andriod devices.
• Import/export with Firefox, Chrome, Opera, Vivaldi, iCab, Roccat, Pinboard, Diigo, and OmniWeb.
• Easily organize with tags, hierarchy, or both.
• Verifies bookmarks, fixes redirects, duplicates, can upgrade insecure bookmarks and remove URL cruft.
• Sort (alphabetize) automatically when bookmarks are changed. You control which folders you want to be sorted or not sorted, how to sort them.
• Supports multiple user profiles in Firefox and Google Chrome.
• Scriptable to collect new bookmarks from NetNewsWire or similar apps.

• Now supports Dark Mode when running in macOS 10.14 Mojave. (To see Dark Mode, users must select appearance Dark in  > System Preferences > tab General.)
• Fixed several minor cosmetic defects in the .bmco document window and in alert sheets and dialogs.
• Will now forgetold documents which are found to be deleted or corrupted, as was the behavior prior to version 2.9.1.
• The Agent (BkmxAgent) will now terminate itself immediately if macOS launches a version of it which is not currently installed in BookMacster, Synkmark, or Smarky. This is to prevent more than one agent from being launched if macOS has old versions in its XPC cache, a problem which some users experienced after our last update.
• If macOS has not opened a .bmco document after 35 seconds of trying, app now displays an error message (257938) instead of the Processing .bmco dialog remaining until user force quits the app. (In addition to adding the timeout, document opening is now peformed on a secondary thread.)
• Added a workaround for an apparent bug in macOS Launch Services which may be causing some of those document-opening errors.
• When running in macOS 10.14 or later, when user clicks a round ? Help Button, the relevant help page now opens in the user’s web browser, served from our website. This is a temporary fix, until Apple provides a workaround for their breaking of help anchors in macOS 10.14. When running in earlier macOS versions, the relevant help page still opens in Apple Help Viewer.
