Treat referrers as allow-conditions still blocks

[rcmosher]

Version: 1.6.4
Browser: Firefox
OS: Windows 10

I have LeechBlockNG setup with 1 simple block set:

>duckduckgo.com
>startpage.com
imgur.com
reddit.com
youtube.com

Treat referrers as allow-conditions rather than block-conditions is checked

However, if I click a link to one of the blocked sites from one of the referrers they are still blocked. I've reproduced this on a few machines. My current one only has one block set.

It may be that the referrer is being reported from the content script too late to prevent the block. Try setting a value in the option Wait __ second(s) after page has loaded before checking blocking conditions (under Advanced Options).

Setting Wait __ second(s) after page has loaded before checking blocking conditions works sometimes. But most of the time the page is blocked well before the configured second has expired. But it is not consistent. I have gotten through with high values like 15 or 30 seconds. I'm not sure if it is because they are so high. Or it was just random as it doesn't work every time.

Try this:

• Select "Diagnostic mode" under General options.
• Go to about:debugging, click "This Firefox", then the "Inspect" button for LeechBlock (a console window should open).

The next time a page is wrongly blocked, look at the debugging output to the console, specifically the 'referrer' item. Is it blank?

[rcmosher]

The "referrer" item is always blank. Thought the Network debugger tab shows the Referrer request header is as expected on the initial page load. I assumed this was what determined the header in LeechBlock

Not sure what's going on. I do know that Firefox can be a bit unreliable about passing the referrer info to the referred page. LB relies on this document property to detect the referring site.
