    Fantastic. Works exactly as described so far, only issue I ran into is you have to restart firefox for it to work after installing, but this might be a thing with all addons.
    Don't mind the 1-star reviews: some people just aren't very smart and they put the blame on the program rather than the user.

    Worked perfectly. I have it turned off by default because, obviously, the new formats are better, but sometimes I need the older formats for compatibility.

    Overall very nice to have. Recently I've had to disable it though as it's been causing issues blocking me from accessing Patreon. Could we get a way to exempt certain sites from the addon in the future?

    Edit: Haven't heard anything from Patreon yet, but thank you for the exemption ability and being so open and responsive to feedback! Zero problems, have that 5th star!

    UPDATE: Added an exemption for Patreon (patreon.com, www.patreon.com) in version 0.8. Hope that works for you.

    ----

    Thank you for the suggestion. I looked at how to do it and there is are a lot of user interface bits to build out, so it's going to take a little while.

    Meanwhile, I don't know why a website would be concerned about the changes to the Accept header -- perhaps they look suspicious when image/webp and/or image/avif is removed? If you hear anything from Patreon about it, please let me know.

    Doesn't uninstall properly. Had to reinstall Firefox to unbreak pages using .webp

    That's strange. Disabling the extension should prevent it from making any changes. Any chance that the "image.webp.enabled" preference somehow got set to false in about:config? (I don't recommend setting that preference to false.)

    Where it can, does what it says on the tin and removes this annoying 'improvent' - thanks muchly.

    Absolutely beautiful. I've finally found the thing that solves my image search nightmare that is the WebP. Thank you!

    9gag still saves as webp and when I copy image and paste it, it still pastes it as webp

    From what I can see, 9gag uses a newer method of image substitution: a picture tag listing both webp and jpg options, and Firefox is choosing webp. This extension can't help with that issue. Currently, I recommend behind! to work with that design: https://addons.mozilla.org/firefox/addon/behind/

    Excellent, get rid of webp, heic and all that proprietary rubbish. Stop ruining the web and computing, else in a few years nothing will work any more !

    This addon is a dream that comes true for anyone who hates webp. :)

    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.
