来自 Moltres Rider，3 年前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.

发布于 3 年前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.

发布于 2 个月前Hi, 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.)- 评分 5 / 5来自 Firefox 用户 18285487，2 个月前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. - 评分 5 / 5来自 Dan，5 个月前

- 评分 3 / 5来自 CodeIcannot，1 年前After 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.

发布于 1 年前Unfortunately, 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." - 评分 1 / 5来自 Andrew，1 年前

- 评分 5 / 5来自 Firefox 用户 16974979，1 年前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.
