    Fundamentally, I like webp, but display considerations have to be accounted for. Irvanview64, with all the plug-ins installed, still doesn't play webp for me, and if I transfer images to my phone, I'm not sure how they'll display there. I asked r/firefox on reddit, and this extension got two quick recommendations. I tested it on Vanity Fair and the images I saw in webp were now jpegs. It works, and that's all I can ask for.

    Does not even deserve 1 star. False advertisement. It DOES NOT strip images of webp. EVERY PNG and JPG file STILL downloads as webp. I tried like 20 different images from like 15 websites that are clearly JPG and PNG, ALL try to save as webp.

    When you enable the extension (stop sign showing) the Accept header should no longer list image/webp. You can check on https://www.jeffersonscher.com/res/jstest.php When you disable the extension (yellow warning triangle is showing), the extension doesn't strip out image/webp.

    If yours doesn't work either way, I can think of two possible reasons:

    (1) You are using a private window but didn't enable the extension to run in private windows. In this case, the stop sign/triangle toolbar button will be missing. See the following article to fix this problem: https://support.mozilla.org/kb/extensions-private-browsing

    (2) There is a conflict between this extension and another extension or proxy that also modifies the Accept header. This could be hard to track down.

    Soooo helpful. Part of my "essential add-ons" after installing a browser.

    Works exactly as advertised. Various websites including Reddit appear to have stopped sending me webP images. I have experienced no side-effects or problems.

    Works as expected, and allows me to reject Google's WebP format, and save images in JPG and PNG format again. Thanks!

    I have image.webp.enabled set to false, I have image/webp;q=0 in my image.http.accept, but sadly some web sites still tried to shove this Google crap down my throat…
    With this extension — not anymore!

    WebP and other "open" formats and codecs by Google shouldn't exist in the first place.
    Thank you for doing god's work with this extension!

    Good initiative. Webp is a crap.

    WEBP is the worst image container format ever invented. thank you for allowing us to block them.

    TLDR: This addon genuinly tries to do what it promises but Firefox defaults + servers = useless addon.
    The addon does something, but it's not resulting in refusal of webp images.

    By clicking the "W" button on the toolbar, the sent "Accept" headers either include or don't include "image/webp", but it's of no use at all if the default following is "*/*".

    It's possible to change the value of the "image.http.accept" key in "about:config" to (for example)
    image/png,image/jpeg;q=1
    but this addon will then not be able to change this value anymore.

    Furthermore, websites such as Youtube (Google in general) just plain refuse to offer anything but webp, even if Firefox does not indicate support for it in the "Accept" header. You may need to fool these websites in assuming you're using an old browser by changing or emptying the "general.useragent.override" key.

    Edited at 14/01/2024: changed rating 2»4; addon is not to blame for servers ignoring user preferences, as indicated in response by addon author.

    Hi Bjorn, the purpose of this extension is to discourage server farms from re-compressing PNG and JPEG images as WebP images on the fly to save bandwidth, since this complicates saving in the original formats. It is not a goal of this extension to prevent sites designed to serve WebP images from doing so.

    > You may need to fool these websites in assuming you're using an old browser by changing or emptying the "general.useragent.override" key.

    That might work, but some sites might serve less useful pages, so you'll have to test and see what is the best compromise.

    Worked for about 5 minutes and then failed, allowing webp files through. I thought it was great while it lasted. It might be that the web site anticipated the add-in and bypassed it's functionality of not recommending webp images.

    The extension should discourage servers from recompressing JPG and PNG images as WebP images -- typically without changing the file name/extension. Can you share a URL of a page that recompresses JPG and PNG images despite the extension? Perhaps I can figure out a workaround.

    In case the problem is cached images from a previous visit to the page, you can clear Firefox's web cache: https://support.mozilla.org/kb/how-clear-firefox-cache

    Note: the extension doesn't block pages like https://developers.google.com/speed/webp/gallery1 from using WebP images when they are part of the design.
