filtrite

filtrite is a project for generating filter lists for Bromite and Cromite. See the page about Custom Ad Block Filters for more info.

Lists

You can choose any list from the table, then hold the name to copy its link. Add it to Bromite by going to settings > AdBlock settings, then setting "Filters URL" to the link you just copied.

Link	Description
Bromite Default	Bromite default filter list, but generated by this tool
Bromite Extended	The default list with additional annoyance blockers I use with uBlock Origin on Desktop
Bromite Extended (Soft)	Same as the "Bromite Extended" list, but with less aggressive filtering (should break fewer sites)
German	The "Bromite Extended" list with additional region-specific blocklists for german sites

Alternatively, you can go here to search forks of this project for more lists, e.g. for other countries.

These lists are regularly updated automatically using GitHub Actions.

Note: I'm not 100% sure if all list formats that are used are actually supported by the ruleset generation tool (as the output indicates some failures). If you have a comment on that, please open an issue :)

Advanced blocking

The normal Bromite ad blocking engine does not support all blocking formats. However, since the introduction of user scripts, it has become possible to block even more annoying elements. If you want more blockers (e.g. for cookie prompts), see my custom Bromite user scripts repository.

Using your own filter lists

This program is designed in a way that allows easily adding new lists.

To create a new list:

1. Fork this repository
2. Enable GitHub Actions by switching to the "Actions" tab of your repo, then confirming that you want to enable them
3. Choose a name for the list, e.g. in the following the name is example-list. Please note that the file name must end with .txt, so in our case we call it example-list.txt (put it in the lists directory).
4. Search for filter lists you want to use. You can for example find them here, use those in "uBlock Origin" or "AdBlock Plus" format (however, it's possible that not all types of rules are supported). Go to info, then "View" and copy the URL to the list.
5. Create a file lists/example-list.txt (in the lists directory) that contains the URLs to filter lists you copied before. It should look like this:

   # Lines starting with # are ignored, empty lines are also allowed
   # List one URL per line:
   https://easylist.to/easylist/easylist.txt
   https://...
   
   # The following line doesn't work, only put either a comment or an URL in one line, not both
   http://  # Invalid comment on URL
   

6. Save your file, commit and push. GitHub Actions should now build the list and create a release
7. After GitHub Actions generated the release, you can copy the linked URL in the release to always get the latest generated version. This URL looks something like https://github.com/USERNAME/filtrite/releases/latest/download/FILENAME.dat. If your URL (except for the username/filename part) contains numbers, you copied the wrong link.
8. Check that the generated filter file size is less than the allowed maximum of 20 MB. If it isn't, you must remove some lists
9. Set this URL as the filter file in Bromite settings.

Another thing to note is that GitHub disables scheduled workflows after 60 days, meaning that you sometimes have to commit something to keep your fork "alive".
