Yes, 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.

Hi, there is one new permission in version 0.9, the "management" permission, which allows checking the names of your installed add-ons and whether they are enabled or disabled. You can see the added code in the comparison page on Github: https://github.com/jscher2000/dont-accept-webp/commit/25eea9332a3819f5d0c9c224b7178bd3db830694

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/

And if you do not trust me, don't run my add-ons.

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

(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.

Hi Niklas, if you right-click > Open Image in New Tab before dragging, the tab should tell you the true format (hold your mouse over the tab to see the full tooltip).

You can test using https://i2.wp.com/radical-mag.com/wp-content/uploads/2019/08/@Test-BMW-320d-8.jpg -- normally, if you hover your mouse over the tab, it will say it is a WEBP image; with the extension enabled, it should be a JPG image.

If it doesn't work on that one, check whether it's the private window issue: https://support.mozilla.org/kb/extensions-private-browsing
