Don't "Accept" image/webp
This extension removes image/webp and/or image/avif from the list of formats Firefox tells sites that it accepts. That discourages many servers from replacing JPEG and PNG images with WebP/AVIF. (But some may send them anyway; they aren't blocked.)

| 2024-11-12 | Firefox user 18285487 | | Great idea. Lossless WebP is generally a superior alternative to Png (except it cannot handle HQs beyond 16k on a side), but when you get served a webp on a web site, there is a 95% chance it is just a Jpg that has gone through another round of lossy compression, a different type, at a lower bit rate = worse quality (fewer fine details). In an ideal world, the digital master would be encoded as both Jpg/Png and Jxl, and the browser would have an option built in to preference one format over the other. JpegXl is the best new format. Jpeg2000 was decent but I don't think any browsers support it, and it even has a lossless format. |
