The update pop-up is set to be displayed only once. There may be something wrong with your browser, ie if you use sandboxing or a single browser profile across multiple devices.

Sure! Thanks for reporting!

Yeah, I see it's reported to me, they have changed something on the website... It will be fixed in the next version. You may also let them to check which cookies you allow them to install and stop bothering you: https://www.i-dont-care-about-cookies.eu/cookie-installing-permission-header/

You can disable that feature in extension options, there is no need to uninstall it.

The notice is set up to be displayed only once, when the extension gets updated to version 3.0.2. If you see it more than once (in a single browser), there might be a bug in the browser itself. If you can, please send me more info about it. You can also try to uninstall the extension (I guess you've already done that part hihi) and install it again after the browser restart. That may help.

Also, if you have some kind of sandboxing software like Sandboxie, it can cause this kind of problem with addons, you should see the instructions provided by sandboxing software developers.

More info, please. Which pages did you visit when you saw this problem?
