Question

linux

After updating Ubuntu in the Chromium browser, some kind of Custom Search System (google custom search) was installed by default as a search engine.

This is not convenient when typing a query in the address bar.
And in the browser settings, the ability to change the default search engine settings was blocked.

How to fix this? Thank you!

Answer 1

I suggest making the screenshots even smaller.

Answer 2

on the second screen, the item "management of search engines" are there options for other search engines inside? when you hover over them, the "set default" button pops up?
