How to exclude viewed search results Google, Yandex?

Question

Browsers

I want to be able to exclude from the search results (Google or Yandex) those results that I have already viewed.
Let's call this option the letter F (filter).
That is, for example, starting from the moment this option is created and enabled, each search will record links that are found among the results on this page (or better, those results that fall into the field of view - in the screen area). And in subsequent searches, these links will be excluded from the results.
Then this business can be developed and created different "sessions" (let's call it that for now). These are sets (lists) of such exclusion links. That is, let's say we enable the F option, after which you need to either select a session or create a new one. Only one session can be open at a given time. And all new search results are applied to this currently open session.
I think that it will be useful when preparing (creating) datasets.
And in general, if you often have to search for certain queries or on a specific topic, then each time the search returns almost the same thing.
Example:
I go to Google images, I drive in "cats".
By default (with the F option turned off), each time I click "search", I see the same results.
I turn on the F option. I create a new session called "cats" (the goal is to search for different cats)
And each time I click "search", I see different results (different cats).
Now, for example, you need to look only for kittens. I create a new session "kitties", search for "kittens" or "little cats" etc. and every time I see new kittens. At the same time, only links of this session — kitties — are excluded from the search results.
Then if I want to look for cats in general (not just kittens) again, I will select (switch to) the cats session.
I understand that the longer it takes to search for cats, the larger the file (files) of the cats session will be and the longer the formation of search results.
Then, in a good way, you will need to learn how to exclude links with the same pictures
(There is an option to store them in a reduced form, for example, 32x32), add certain sites to exceptions, etc., but these are details.
Do I understand correctly that it is better to write your own browser for this?
Does anyone have similar experience? What to pay attention to? Maybe there are some resources to read on this topic.

Answer 1

Links that you've viewed are purple, links that aren't are blue. Based on this, write a plugin that injects scripts and the script hides these links.
