    suddenly asking for a whole bunch of strange permissions suspicious as hell

    Developer response

    posted a year ago
    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.

    This add-on now wants some very strange permissions. It is apparently to prevent conflict with another add-on but I don't see why these permissions are required for that. I'd be very cautious of this for the time being

    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.

    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.

    So good! Thanks, this webp format is the worst and it can deliver a virus onto computer! Watch out

    If you're trying to copy images from Reddit and paste them into WhatsApp, this is the extension you need.

    been using for months & works awesome pretty much always. i hope you find 100 dollars on the ground

    Works great and as advertised, but I have a weird bug where the webp images do not load, kind of annoying unfortunately.

    EDIT: Nevermind the bug was my own fault not the add-on's.

    Great extension. Thank you.

    I haven't tried this extensively, but when I drag an image from Firefox to file explorer it is saved as a jpg, but it's still a WebP image only with a renamed extension. Not working as intended.

    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

    If you want to send me some problem URLs, you can create an issue at https://github.com/jscher2000/dont-accept-webp/issues or email me at jscher2000@outlook.com.

    Doesn't seem to do anything at all, even after closing and restarting Firefox.

    In a world where some sites lossily convert into webm to save 10kB of bandwidth, this is a godsend. Thank you.
  • by smow, 2 years ago
    It used to work pretty fine but for some time it doesn't work at all. Still all webp images are accepted.
  • by Ericb45696, 2 years ago
    It's worked great for the most part for years now but seems to not work on some sites for whatever reasons. Updated, and I tried changing settings back and forth but some sites it just does not work on. Imgur for example, it wont work if I'm on the main page, but if I go ahead and click on an image and then try it , it works. odd. Seem to be finding more sites it just does not work on lately, but it still works on most at least.
