Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/120.0

Steps to reproduce:

  1. Tried to save JPEG image, saw that it was WebP instead.
  2. Verified that image.webp.enabled is false.
  3. Checked HTTP headers and saw that FireFox included image/webp in Accept header.
  4. Started Firefox 112 with a fresh profile and verified that the setting does work in the older version.

Actual results:

Unable to save JPEG images because the server sends WebP instead.

Expected results:

Firefox should not include image/webp in the Accept header when webp is disabled.

This is a regression somewhere between version 112 and version 127.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: ImageLib' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

There's is no longer a image.webp.enabled pref.

I'm going to mark this invalid based on the pref no longer existing.

If you wish to request the accept header be modifiable by pref or add-on, that code is in the networking component so you can either file a new bug in networking or morph this bug into that.
