cannot see the Safari Reading List anymore

I presume you mean the Reading List in BookMacster, which should contain the bookmarks in Safari's Reading List after importing from Safari.  The Reading List should certainly make the journey because it is the same file – there is no journey.

Hmmm, this could happen if you created a new .bmco document in BookMacster instead of opening "Synkmark.bmco".

It could also happen if the Client Safari did not make the journey, although that should not happen either.  But assuming something went wrong, the Reading List could be named Other Bookmarks if Firefox precedes Safari in the list in Settings > Clients or if Safari is absent from Clients.  Moving Safari to the top (using the up-arrow buttons in the Clients list) should change the name of that folder back to Reading List.

Am I understanding the problem correctly?

Ok so something weird happened.. Before when i was just using SynkMark... I could see Safari Reading List... When i added something to the Reading List in Safari, that URL would show up in Bookmarks on Firefox.

Now after upgrading to BookMacster, I do not even see the Safari Reading List anywhere.

Real quick, I am using Synkmark not BookMacster. Will this only work in BookMacster as it has the "collections" feature?

Hello, Redman.

Thank you for contacting us.

I was thinking how to write a Sorry, no response, but then from way back in my memory I remembered that we added features to do this a few years ago.  I just tested making such a Fake Reading List in Firefox, and by golly it still works 

There is even an article in the Help Book which explains how to cofigure a similar thing, for Chrome.  For what you want, do this:

• In BookMacster create a folder named something like "Fake Reading List", which will be your "Reading List" in Firefox.

• In Settings > Clients > Safari Advanced Client Settings > Tag ↔ Folder Mappings section, click the "[+] button and add a Folder-to-Tag Mapping which acts during Import, tagging any item from the hard Reading List with a special tag, such as "to-read".

• In Settings > Clients > Firefox Advanced Client Settings > Tag ↔ Folder Mappings section, click the "[+] button and add a Tag-to-Folder Mapping which acts during Export, moving any item with your special tag into the Fake Reading List folder in Firefox.

• Set an Export Exclusion so that the "Fake Reading List" folder is not exported to Safari.

• Click in the menu: File > Export to all, to export your still-empty "Fake Reading List" to Firefox.

Now, whenever you import from Safari (or whenever our Agent imports from Safari while BookMacster is quit due to a change in Safari), items in Reading List will get the special tag.  And whenever you export to Firefox (or whenever our Agent exports to Firefox to effect syncing), those same bookmarks will be exported into the "Fake Reading List" in Firefox.

I think you could also add two more mappings to make it work in the other direction too – items added to "Fake Reading List" in Firefox would be moved to the hard "Reading List" in Safari.

This probably warrants me making a 5-minute movie explaining how to do it, if for no other reason than so I don't forget again   Tell me if you think the movie would be helpful and I shall do.
