Hello, I am looking for a way to add a URL blocklist to the Firefox browser. I’ve seen some posts on accomplishing this through modifying a json file at browser startup but am lost in the process. Does anyone have any clarification on setting this up?
Best practice is for your company security / network team to setup a proxy for web traffic so that they can audit / track URLs.
Then all you have to do is enable web proxy in Browser (Firefox or Chromium).

Another option is to setup a non-existent proxy and then provide the list of URLs that are allowed.
No proxy for: List of URLs for which no proxy is to be used
Hi Ron, I am currently using an allow/block list for chromium. We have not tinkered much with Firefox. Do you have a UMS path that this can be accomplished with?
I do not.
If you are blocking a domain, just add a host file to send it to nothing
i.e.
http://google.com google.com -> 127.0.0.1
That blocks it everywhere
@member there are possibilities in the Firefox browser to block specific URLs or also to let users only access specific URLs, similar like in the Chromium browser. Personally I prefer the Chromium browser, because the configuration options are better described there and easy to configure. Unfortunately I don ́t found a easy and fast solution to configure the specific Firefox preference in the IGEL profile, because the options to configure custom browser policies/preferences with IGEL profiles have a lot of room for improvement.
Here’s my idea:
You have to configure the following custom preference, which can be done in the policy.json file from the Firefox browser. (The policy file is saved in IGEL OS under: /services/fbrw/firefox/distribution/policies.json)
Policy name: “WebsiteFilter”
Policy value: {“Block”:[“:“,”:“]}
…in the policy.json file it could configure with the following line:
“WebsiteFilter”:{“Block”:[“:“,”:“]}
(youtube.com youtube.com replaced with your URLs to be blocked)
Unfortunately with the Firefox Browser Global -> Advanced options I couldn’t get it resolved quickly. Maybe somebody can help you to add the line described above with a custom command.

Sorry, I can’t do more in my vacation at the moment. 😕
Why not use a hosts file to send traffic to youtube.com youtube.com to a bogus IP, like localhost?
