What I want is a History functionality that allows me to better search through visited pages. Firefox does this, but they only show the page title, which is often not sufficiently descriptive. They should show search results like DDG/Google shows them.
With a better search, I wouldn't feel the need to keep so many tabs open.
That’s what was “to be native” in Cliqz. They were indexing url, title and I’m not sure about content was in plan or implemented - forgot my trials. But they approached exactly that issue in their browser (Firefox fork). There was something like internal index which was pre-fetched and updated next to user data which were added while using. All that was 1 search, 2nd was going to internet. That was really cool idea.
