## New

New filtering ability to remove specific response headers from document resources. Example:

    example.com##^responseheader(refresh)

Only the following response headers are allowed to be removed, anything else will cause the filter to be invalid and discarded:

- `location`
- `refresh`
- `report-to`
- `set-cookie`

### Chromium-based browsers

[Google's FLoC](https://www.eff.org/deeplinks/2021/04/am-i-floced-launch) is defused by default. Websites will be able to use the FLoC API (only if already present), but will be unable to get a result from it -- uBO causes the API to always fail as if there was no FLoC data available.

If your Chromium-based browser supports the FLoC API, this is the result you should get with uBO when testing with [EFF's _"Am I FLoCed?"_](https://www.eff.org/deeplinks/2021/04/am-i-floced-launch) (assuming you did not disable uBO's _"uBlock filters -- Privacy"_ list):

![Fetching FLoC data fails](https://user-images.githubusercontent.com/585534/115114281-742f5a00-9f5c-11eb-9e77-4642da2d1d6f.png)

Additionally, uBO causes all websites to opt-out of being part of FLoC calculation by injecting [the appropriate response header](https://github.com/WICG/floc#opting-out-of-computation).

You can opt-in to FLoC by creating the appropriate exception filter, see [commit message](https://github.com/gorhill/uBlock/commit/bfdc81e9e400f7b78b2abc97576c3d7bf3a11a0b) for details.
