This extension is great, but it is limited by the way things are trending online these days. More and more sites aren't letting you block them from sending the stupid WebP format to your browser, but for the ones that still allow it, this extension is perfect. Until more graphic editing programs natively support this new format, I will continue to use this extension to block it as much as I can.

People saying it doesn't work clearly haven't bothered to read the developer's notes about it. They explicitly state "sites are MORE LIKELY to send JPEG and PNG format images." Nowhere is there a guarantee that this will block WebP, it simply stops Firefox from telling sites it accepts it. Some sites ignore that and send WebP anyway, while others will comply and send you the original format, whether that be JPG, PNG, whatever.

I find that somewhere between half and two thirds of sites I visit that typically send WebP images will send the original formats when I use this extension. That's not perfect, but it's better than what I get without it, and with the way browsers and sites talk to each other, I don't think it can be improved beyond that.

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

It works. I get jpeg sometimes instead of webp.

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

I wonder how

TipTop, endlich wieder vernünftige Datei-endungen

Works as intended!

Works as intended. Thank you very much jscher2000

Good

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

Works great so far!

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

Really helpful

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.

I am so annoyed by the webp format as someone who collects art references on the internet for private use, and no reference program supports webp. Webp is a scourge on the internet and I am glad this plugin exists.

Thank you
