Screenshot of it asking? I never got this ask-I myself had to make pin to Taskbar command to make it happen.

Thanks for responding @Dropa If you've never seen it, then I reasonably assume you've also never solved the question asked. Nonetheless, it's may be additional info that it doesn't happen on every installation.

For those that may know if/how to solve this: o My Firefox version is 100.0.1 (64-bit) o Anecdotally the popup seems to happen ~once a week o Maybe triggered by an update (idk)? o Most recent was today

I have pin many things to the taskbar and never had issue doing this. I am using Windows 10 with latest updates and software updates and FF100.0.1 and can make Pin to taskbar without issue-so there was issue to be solved. I used Windows since 95 and only from 7 to 10 did I do Pin to Taskbar and had no issues doing so. I even PinToTaskbar-Chrome and FireFox icons and open from there without issues. And Notepad and Epub reader and they worked single click to open and run. And say it again never heard FireFox "Ask" to PinToTaskbar. So your going to have to get a screenshot of it saying this - I suspect something else is doing this other then FireFox.

@ Dropa Erm... ok. So to confirm: you're saying (twice now): a) You can't help me, and b) You don't even believe it's happening. Given this, I'm not sure why you'd bother responding at all. As it isn't helping me...

For your edification, attached is a screen shot of the message. I hope that helps you understand just because you haven't seen something, doesn't mean it doesn't exist.

For anyone else reading this: Still haven't worked out how to turn this off (and am starting to believe one simply can't)

For anyone who can do anything about this: Could you please add "Don't ask me again" to the options?

That's coming from duckduck from the screenshot. Nothing mentions it's a notification from firefox.

No it isn't. Can you please leave this is others?
