Blocksite stopped working suddenly without apparent reason [Firefox, Windows 10]

[Ironbull200]

I've been using Blocksite for a couple of weeks now and it worked great. However, today it just didn't anymore all of a sudden without any obvious reason as to why. My custom rules are all still listed properly on the options page and all the settings seem to be the same as before.

To give you an example, if I add the rule R:example the URL "https://www.youtube.com/results?search_query=example" should be blocked and it WAS blocked until yesterday. However, for whatever reason, it doesn't get blocked anymore. I can't pinpoint when Blocksite stopped working exactly; I noticed it when I tried adding a new rule and was confused why it wouldn't work. Then I tried an already existing (and properly working) rule and saw, that it didn't work either anymore. That's when I knew something was broken.

Troubleshooting steps I tried already:

• I checked about:debugging but nothing gets listed there at all.
• I checked if either Firefox or Windows made an automatic update that might have broken something; both was not the case as far as I am aware.
• I also suspected, that maybe my rules were too many in number (~320 currently), so I tried deleting them and trying with just a single rule. Not even then it worked anymore.

My system is a Windows 10 machine (Version 10.0.19043 Build 19043), Firefox version 99.0.1 (64-Bit), Blocksite version 0.3.5, the addon gets force-installed via a policies.json.

Any help would be greatly appreciated!

Edit: Now it started working again on its own, wtf. Can somebody explain to me what is going on and how I can make sure this doesn't happen again?

Can you share the JSON file of the preferences? You must have a rule that breaks the blocker.

I'm having the same issue, BlockSite doesn't seem to be working on Firefox on Linux for me

@arjunnnnnnn Please export preferences on the options page and share them here.

@ray-lothian here's my preferences.json - the only rule I had was for google.com :

{
  "blocked": [
    "google.com"
  ],
  "close": 0,
  "contextmenu-frame": true,
  "contextmenu-pause": true,
  "contextmenu-resume": true,
  "contextmenu-top": true,
  "css": "",
  "initialBlock": true,
  "last-update": 1658718891776,
  "map": {},
  "message": "",
  "no-password-on-add": false,
  "redirect": "",
  "reverse": false,
  "schedule": {
    "times": {}
  },
  "schedules": {},
  "sha256": "",
  "timeout": 60,
  "title": true,
  "wrong": 1,
  "managed.storage.overwrite.on.start": false,
  "guid": "f8cb8098-cf72-4d06-ae9d-cfb8ca2e9a3b"
}

This was a recent install so hopefully it's not me that only has the problem

I don't see any problem with these preferences. Anyhow, I've just submitted the 0.4.4 release to AMO. From this update, Firefox is going to follow the latest changes. Hopefully, the update fixes your issue. If not, please report back so that we can debug.

~~So I tested it with version 0.4.4.1 - seems to work for google.com but not other domains~~

It appears to work now - I forgot to click "Save options" - please disregard my previous message
