Thanks! BM 2.9.7 did the trick. When I first updated, nothing happened - I'm guessing a reboot or re-login was necessary - but it's good now.

You are not seeing the Add… menu item in either Safari or Firefox 

Do you see it in any web browser?

There are, several conditions which must be met for a web page to appear in the Add… menu item of BookMacster's or Markster's menu extra.  Please check these:

• Except for the Safari web browser, either our BookMacster Sync or BookMacster Button extension must be installed, enabled and loaded in the web browser you wish to land new bookmarks from.  A couple years ago there was trouble if you had both of our extensions installed, but that issue was supposedly fixed.  If you install the BookMacster Sync extension, there is a button in the Manage Browser Extensions window to Test it.

• A web browser (Firefox, Safari, Vivaldi, Opera, Chrome, etc.) must be the active application; that is, the one whose name appears after the apple in the top left corner of your screen.

• For Firefox, the active "Profile" must be one that has our extension(s) installed.  For Chrome, the active "Person" must be one that has our extension(s) installed.

• The web page you want to bookmark must be the web browser's frontmost window.

Hello, JT.

Thank you for contacting us.  I think you mean that the Add <whatever> menu item in BookMacster's Menu Extra, which magically appears whenever you click the Menu Extra while visiting a web page in a web browser does not appear.  It does appear when you are visiting a web page in a different browser such as Firefox.

Pleas reply and tell me if I am wrong.

Anyhow, if I have described the situation correctly, this is what happens when one of Apple's little enhanced security gifts in Mojave goes wrong.  In the following, I describe what happens when you try to add from the Menu Extra in BookMacster, but the story is the same if you use the Dock Menu, or the Global Keyboard Shortcut, in BookMacster, or Markster.

To populate that menu, when Safari is active, BookMacster asks Safari for the name and URL of the current web page via AppleScript (because, sadly, Safari does not provide any more reliable means).  Aha! says macOS.  Some app may be trying to steal which web page you are viewing!  What should happen, and I think this has happened for most users, is that, the first time you click our menu extra with Safari active, macOS displays a warning dialog asking if it is OK for BookMacster to play with Safari.  Then when you click Allow, a new entry, BookMacster > Safari, appears in System Preferences > Privacy > Automation, with a checkbox that is switched on.  And that is permanent, so the next time and the next day when you do this, macOS allows Safari to pass its information to BookMacster, and everything works.

I think it has worked that way for most users.  But I'm guessing that if something goes wrong during that first interaction, BookMacster > Safari does not get added to the System Preferences > Privacy > Automation, and the next time and the next day when you click our menu extra, instead of asking again, macOS simply refuses the connection and hands BookMacster an error.  Furthermore, there is no way to manually add allowed connections to the list in System Preferences > Privacy > Automation.

I've done a lot of experiments but cannot find a workaround.  If anyone finds one, please tell us.  I plan to submit a technical support incident to Apple tomorrow morning.  An answer may take several days to a week or more
