DO NOT INSTALL THIS PLUGIN. MASSIVE SECURITY RISK!

This plugin recently changed the permissions it wants you to grant it to access ALL of your data used on websites. This means this plugin can now collect cookies, passwords, whatever it wants if it so chooses. The plugin creator "assures" you it's not collecting data, but there is simply no way to be sure. I heavily recommend deinstalling this plugin immediately. The plugin didn't need said massive security risking permissions to work before, and that it needs them now is extremely fishy. My personal guess is that the creator/s bank on people just updating the permissions without reading the permission changes, to then collect user data and sell it. So. DO. NOT. INSTALL.

Actually, this add-on has ALWAYS needed and requested the "< all_urls >" permission in order to modify requests to websites. That is *not* new, but probably you have become more security-conscious since you originally installed it. We should all be careful, and there is a support article on this: https://support.mozilla.org/kb/tips-assessing-safety-extension

If anyone prefers to install the previous version, you can grab it from the All Versions page at: https://addons.mozilla.org/firefox/addon/dont-accept-webp/versions/

(What *is* new in version 0.9 is checking whether you have another add-on known to have a conflict with this one.)

For what it's worth, I still have no interest whatsoever in what you are doing in your Firefox, and there's no way for me to know because this add-on still doesn't send me any data. If you don't believe me, then don't use the add-on.

    Невероятно полезная вещь, наконец то открывает jpeg а не богопротивный webp

    Hi, it depends on the site design. You can test on Total Wine glassware page (https://www.totalwine.com/accessories-more/accessories/glassware/c/001555). Use the Page Info dialog (Ctrl+i, Mac: Command+I) Media list to check the image formats. Reload after changing the "Strip image/webp" setting and check again. With the extension stripping webp, the original formats (PNG, JPEG) are used. If that doesn't work for you, check this article just in case: https://support.mozilla.org/kb/extensions-private-browsing

    If there are specific sites you would like help with, you can try creating a new issue at https://github.com/jscher2000/dont-accept-webp/issues or emailing me at jscher2000@outlook.com.

    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
  • by Firefox user 18285487, 8 months ago
    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).
