URLs mistakenly flagged

[evilpie]

Thank you so much for reporting this issue here! Sadly, I can't reproduce it.

As you can see I bookmarked your pages and none show up as expired. What text is inside the parentheses () after the links?

The Expired bookmarks and Other bookmarks headings are new since I last uninstalled the extension.
I hope this helps:

Very strange indeed. Do you have some VPN or local proxy? Can you try disabling every other extension?

[Dennywuh]

I have a direct fibre optic connection, no VPN, no proxy, no firewall other than Windows Defender. I do keep my Hosts file updated from http://winhelp2002.mvps.org/hosts.htm but I can connect to those sites without a problem, so that's not it.
Some of the sites I blanked in the uploaded image are Facebook URLs. I intentionally block facebook.com, facebook.net and fbcdn.com with uBlock Origin, so I expect them to be unreachable.
I've disabled all other add-ons, restarted and tried again and now the Facebook links work but the others still appear in the Other bookmarks list, except www.bellazon.com, that's not there anymore.

Yeah sorry, seems like other extensions are at least partly to blame. What version of Firefox are you using?

[Dennywuh]

Firefox Quantum 57.0 (64-bit).
I'm sorry, I don't think other extensions are involved. When I disabled them all except 404 Bookmarks nothing changed, apart from the Facebook URLs becoming available because the uBlock Origin extension that usually blocks them was disabled.
I'm finding that some links are flagged as not-working only temporarily. Bellazon.com, for instance, only appeared once, early on. Since then various others have turned up on the list once and never again.

Maybe I just need to add some code to retry those URLs a few times.
