additional decoder compression options

It would be really useful if decoder had options to deal with deflate and brotli as well as gzip ...

Yes, I agree. These are on the development plan, although with the current focus on Burp 2 are likely to be a little way out. In the meantime, the Decoder Improved extension supports deflate.

This would not only be useful in the Decoder, but also support for Content-Encoding. Brotli is supported by browsers: https://caniuse.com/brotli I have a case where Burp will only show gibberish because "Content-Encoding: br"... Inspector is of no help, Decoder is of no help, only Hackvertor works. When I ActiveScan it's of no use because Burp won't recognize that it's actually br encoded HTML, so missing basically every vulnerability class there is.

Thanks for your feedback. This is still in our development backlog, unfortunately. We will update this thread with any further information in the future.
