Why I see an error in Firefox?

||connect.facebook.net^$script,from=/\/*\web.securenetsystems.net/

Can you paste the filter which is erroring here? Transcribing from the screenshot is kind of tedious.

||connect.facebook.net^$script,from=/\/*\web.securenetsystems.net/

The parser for regex-based domain doesn't expect / characters inside the regex, as these never appear in a hostname. From your screenshot, it appears what you want is really (edited to remove pointless leading .*):

||connect.facebook.net^$script,from=/web\.securenetsystems\.net$/

I do see the same error in Chromium:

---

I see no error in 1.60.0 because the parser for network filter option was re-worked to better detect option boundaries. It 1.60.1+ it ends up extracting /\/ as the regex, which is an invalid regex.

||connect.facebook.net^$script,from=/.*web\.securenetsystems\.net$/

Tnx, this works for me.

[gorhill]

By the way, why not just use:

||connect.facebook.net^$script,from=securenetsystems.net

Avoiding regex whenever possible is preferable if this accomplish desired result.

Yes, securenetsystems.net does not have a request to facebook.net

||connect.facebook.net^$script,from=securenetsystems.net will be applied to all subdomains of securenetsystems.net.
