## Warnings

#### Regarding broken sites

µMatrix do not guarantee sites will work fine: it is for advanced users who can figure how to un-break sites, because essentially µMatrix is a firewall which works in block-all/allow-exceptionally mode out of the box: it not unexpected sites will break.

**So this means do not file issues to report broken sites when the sites are broken because µMatrix does its job as expected.** I will close any such issue without further comment.

I expect there will be community driven efforts for users to help each others. If µMatrix had a home, I would probably set up a forum, but I do not plan for such thing, I really just want to code, not manage web sites. If you need help to un-break a site when using µMatrix, you can try [Wilders Security](http://www.wilderssecurity.com/threads/umatrix-the-http-switchboard-successor.369601/), where you are likely to receive help if needed, whether by me or other users.

µMatrix can be set to work in [allow-all/block-exceptionally](https://github.com/gorhill/httpswitchboard/wiki/How-to-use-HTTP-Switchboard:-Two-opposing-views#the-allow-allblock-exceptionally-approach) mode with a single click on the `all` cell in the global scope `*`, if you prefer to work this way. This will of course break less sites, but you would then lose all the benefits which comes with block-all/allow-exceptionally mode.
