The software giant first introduced malware-like pop-up ads last year with a prompt that appeared over the top of other apps and windows. After pausing that notification to address “unintended behavior,” the pop-ups have returned again on Windows 10 and 11.
Windows users have reported seeing the new pop-up in recent days, advertising Bing AI and Microsoft’s Bing search engine inside Google Chrome. If you click yes to this prompt, then Microsoft will set Bing as the default search engine for Chrome. These latest prompts look like malware, and once again have Windows users asking if they are legit or nefarious. Microsoft has confirmed to The Verge that the pop-ups are genuine and should only appear once.
Ublock Origin does not block "malicious Javascript" reliably. You need NoScript for that, and a opt-in approach. Block everything, unblock what you need, hope its not malicious.
That probably is a Ublock origin filterlist. Did you ever open UBOs settings? Try to not use too many, too many lists increase RAM and CPU usage and are all using badness enumeration so they will be 80% duplicates.
I dont know if UBO deduplicates them (removes duplicates), that would make sense.
And sometimes it prevents sites from working, because paywalls that are avoidable by blocking the cover are deprecated and nowadays real solutions are used. This means such size will just break.
Ublock can also remove overlays, and I am sure it you add more lists they will be blocked by default.
Having less code run in your browser is always recommended.
I have nothing to do with Librewolf at all. Don't confuse the two. I just said what Duckduckgo did with trackers based on a search agreement with Microsoft. BTW, this issue was initially exposed by others, not Duckduckgo itself.
