DO NOT INSTALL THIS PLUGIN. MASSIVE SECURITY RISK!
This plugin recently changed the permissions it wants you to grant it to access ALL of your data used on websites. This means this plugin can now collect cookies, passwords, whatever it wants if it so chooses. The plugin creator "assures" you it's not collecting data, but there is simply no way to be sure. I heavily recommend deinstalling this plugin immediately. The plugin didn't need said massive security risking permissions to work before, and that it needs them now is extremely fishy. My personal guess is that the creator/s bank on people just updating the permissions without reading the permission changes, to then collect user data and sell it. So. DO. NOT. INSTALL.

发布于 1 年前Actually, this add-on has ALWAYS needed and requested the "< all_urls >" permission in order to modify requests to websites. That is *not* new, but probably you have become more security-conscious since you originally installed it. We should all be careful, and there is a support article on this: https://support.mozilla.org/kb/tips-assessing-safety-extension
If anyone prefers to install the previous version, you can grab it from the All Versions page at: https://addons.mozilla.org/firefox/addon/dont-accept-webp/versions/
(What *is* new in version 0.9 is checking whether you have another add-on known to have a conflict with this one.)
For what it's worth, I still have no interest whatsoever in what you are doing in your Firefox, and there's no way for me to know because this add-on still doesn't send me any data. If you don't believe me, then don't use the add-on.

发布于 1 个月前Hi pjcamp, thank you for your report.
This extension makes a change to how Firefox requests images, but many sites ignore the change. If there is a specific site you want to mention, you can contact me by creating a new Github issue on https://github.com/jscher2000/dont-accept-webp/issues or emailing jscher2000@outlook.com.
On the other hand, if it fails on every single site, check for this issue: https://support.mozilla.org/kb/extensions-private-browsing
There also are some pages that give Firefox multiple format options (picture tag/source tags) and it selects WebP for some reason. I don't have a fix for that yet.- 评分 5 / 5来自 Crowbar Scientist， 2 个月前

发布于 4 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 4 / 5来自 Firefox 用户 18285487， 5 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.
Unfortunately, this extension only works on some sites. Some are still sending me Webp,oravif (less often) and even twice I got a Jpegxl (I wish to force jpeg from these bossy CDNs that are enforcing inferior formats upon me). - 评分 5 / 5来自 Major Gear， 1 年前This addon installs easily and does what it says on the tin. I recommend this addon.

- 评分 5 / 5来自 Firefox 用户 18347256， 1 年前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.

- 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."
