Blocks whitelisted sites and unable to unblock

[qwerty-fortytwo]

After updating firefox quite a while ago did the blocker stop working some of the time. It works in most cases but not always.

I run it in reverse (whitelist) mode, allowing only listed sites. This have worked as expected previously but donesn't work anymore.
When a site was blocked before was I given an option to unblock or whitelist that site, now I only get a "restricted adress" page where "Title", "URL" and "Blocked since" fields are ... Trying to unblock does nothing.

A few of the sites I have unblocked (and that worked before) doesn't work anymore. I have tried removing and re-adding them in the settings page with no result. An example of one such page is farozon.se

block-site-preferences.json

I'm having the same issue when I tried switching over to reverse mode. When hitting add to whitelist page refreshes and *://.../* gets added to the whitepage list. This changes nothing, going back to the desired url you still get blocked.

I tested adding YouTube to the whitelist manually and that granted access. However if I remove that and try accessing YouTube I get to the Restricted Access page and have the issue stays the same. Can't access the site and can't add to whitelist either.

I'm using version 0.5.2.1 on Firefox
