by sabuncu, 4 years agoUse this extension to prevent Firefox from saving New York Times images as webp. Works great, thank you.

posted 5 days agoHi, 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.) - Rated 5 out of 5by Firefox user 18285487, 19 days agoGreat 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. - Rated 5 out of 5by Firefox user 13807639, 2 months agoTipTop, endlich wieder vernünftige Datei-endungen

- Rated 5 out of 5by Firefox user 18347256, 8 months agoExtremely 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.
- Rated 5 out of 5by Asmodeus, 9 months agothis 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.

- Rated 3 out of 5by CodeIcannot, a year agoAfter 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.

posted a year agoUnfortunately, 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." - Rated 1 out of 5by Andrew, a year ago

- Rated 5 out of 5by Firefox user 16974979, a year agoI 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.

Any picture I try to save from nexusmod is shown as webp.
Ex https://www.nexusmods.com/skyrimspecialedition/mods/24791
Or more specifically: https://staticdelivery.nexusmods.com/mods/1704/images/24791/24791-1554680316-435236928.png
Clearly a png which is what I get from chrome. But FF gives me this crap webp even with this add-onDeveloper response
posted a year agoYes, the NexusMods site ignores the change made by this add-on. But for me, the .png file saved from Chrome is the same WEBP file -- with a .png extension.
If you hear of any way to fool the site, I can try to implement it. Until then, when you are viewing the image in its own tab, you can get Firefox to download it as a PNG by using the built-in screenshot tool. Either right-click the blank area above/below the image > Take Screenshot, or use the keyboard shortcut (on Windows, Ctrl+Shift+S). Then move the mouse toward the upper left of the image and a dashed rectangle should appear around the image. Click to select the image, then click the Download button. The file name is a mess, but it will be a true PNG file.
