Delicious Library 3.9

I was curious about this app, but when I try to visit their site, Firefox shows the following:

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

I’ve been using Delicious Library for years and have not been able to open it since upgrading to Catalina so jumped at the change to up grade to 3.9 and got to the web site with no problem in Firefox. I downloaded and have installed 3.9 and it will not open either. Checking with the developers…

We’d investigated Delicious Library and purchased it some time ago. We were going to use the mobile app to go down the shelves and get an idea of just what we had. I’m an archaeologist and she’s a planetary geologist so we have A LOT on the shelves.

We only got a small sample in when we got distracted by moving halfway across the country.

Hadn’t even thought about it until I saw the TidBITS article so I updated.

After the ‘install and restart’ my library was empty and there was the old app, several folders and .plist files and other stuff in the trash which I removed and put in a separate folder.

I’m going to contact tech support now. I am glad I only had several dozen entries in the database. I’ll post again if I find anything out.


I was able to restore all

I rummaged around and found a version 3 data file in the trashed files which I was able to restore from from the ‘import’ menu.

Apologies for the excitability.


Still running low Sierra. I downloaded the new version with Firefox and dropped in Applications. Took it bit longer to open than before on first
launch. It just worked.

My data file seems fine with 1,540 items.


I use the Mac App Store version, so updating was uneventful.

May I also remind everyone that Bookpedia is a viable alternative to Delicious Library?

I’ve used Library Thing for years. I used to have a massive library (about 6,000 books) before I retired. I used Library Thing when I went to my last church but we were out in NE NC where internet flows slower than a slumbering stream so it really limited my ability to get everything online, even using a hand scanner. But it is very worthwhile and it has helped me locate other sources for some of the books.
