There’s still some issues with the website filtering. Try switching the option “ask” to “block” and it’ll block the page from even trying to load and that may resolve the issue. You can also use use wildcards e.g. facebook and it’ll block any URL containing that word.
I think it has something to do with Firefox running in containment. I get a few entries in normal or private browsing where the browser tries to connect to facebook but no browser or sysem lags or spikes.
I’ll wait and see if one of the other Mods or Devs have more knowledge on this,
Step 1
I had created a category with several sites.
I had created a rule with this category with the following parameters “Everyone”, “Block”, “Logs”.
I activated the rule.
I have not noticed any difference between standard FF and FF in the container.
There are for each activation of a site 3 lines in the log (see at the end of the html file attached from 14:36 to 14:41) and the web page is white without any message informing that CIS has blocked the site contrary to what is expected:
Step 2
I deleted the rule and attached the category I had created to the “Blocked sites” rule.
I made an access to 2 sites and the log file is flooded with events (see attachment from 15:13).
I hope this will help.
Thanks for your feedback.
PS: as I can’t attach the html file, I send you a link by PM.
