In case you are using private windows, make sure you enabled the add-on to run in private windows: https://support.mozilla.org/kb/extensions-private-browsing

If that's not the problem, hmm, could there be a conflict with a different extension that also modifies request headers?

    It doesn't always work on every webpage (half the time on Aliexpress), however it works most of the time.

    Doesn't do anything. Webp images come anyway.

    Hi pjcamp, thank you for your report.

    This extension makes a change to how Firefox requests images, but many sites ignore the change. If there is a specific site you want to mention, you can contact me by creating a new Github issue on https://github.com/jscher2000/dont-accept-webp/issues or emailing jscher2000@outlook.com.

    On the other hand, if it fails on every single site, check for this issue: https://support.mozilla.org/kb/extensions-private-browsing

    There also are some pages that give Firefox multiple format options (picture tag/source tags) and it selects WebP for some reason. I don't have a fix for that yet.

    I wonder how
  • di 64fanatic, 3 mesi fa
    Not working atm. Go to Youtube Community and try to save an image.

    Hi, sites decide what format to serve based on different criteria. This extension only changes the "Accept" header. Some sites check the user agent instead (to see whether it's a modern browser). If you had the problem with a post on the Community tab of a YouTube channel, I see it, too. I don't think Google offers those images in alternate formats. (If I try to download one using the Internet Explorer 11 user agent, I still get WebP.)

    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.

    Unfortunately, this extension only works on some sites. Some are still sending me Webp,oravif (less often) and even twice I got a Jpegxl (I wish to force jpeg from these bossy CDNs that are enforcing inferior formats upon me).

    This addon installs easily and does what it says on the tin. I recommend this addon.

    Fantastic! Does what it's supposed to and doesn't get in the way.

    Really helpful
  • di Utente Firefox 18347256, un anno fa
    Extremely useful and efficient, now I can save an image in it's original jpg or png format, instead of paying 2 conversions jpg-webp then webp-jpg. Should be the default when saving a jpg or png image.

    this is one of the most convenient and helpful add-on in the world, it made my life so much easier when using Reddit and is the sole reason I switched to Firefox.

    After using this add-on for a long time, I'm only giving it 3 stars, because it's very unclear to me, if it's actually accomplishing anything...? There are lots of sites that keep pushing webp and avif files, even when this add-on is in use, and it feels like the number of those sites is increasing, all the time.

    Unfortunately, this add-ons is only effective on sites that pay attention to the "Accept" header. Other users have identified certain sites that ignore the change made by this add-on, such as NexusMods and PlayStation. These sites either no longer support legacy browsers, or require a legacy user agent (such as Internet Explorer 11) before sending legacy media formats. For cases like that, you could consider using a converter. I have one here on the Add-ons site called "Save webP as PNG or JPEG."
