I have 3 questions:
On some webpages, even on popular sites, sometimes bad words come up, how to block them?
And also, on some webpages, even on popular sites, sometimes such language is written that does not contain bad word(s) but the language is such that makes impact like bad words. So, how to block that language or how to convert it to a polite and gentle form?
When viewing a webpage, then how to remove information, that's not related to the subject matter, and only display the main information?
I prefer a solution that is in the form of a software or a browser extension to solve the above three problems. And I prefer Open source software and open source browser extensions more, and please cite sources for any info. I use win. 10 and have Firefox browser.
A basic feature in the software or browser extension should be that the user should be able to add, delete, and edit the list of words and phrases that are to be blocked (this feature can be helpful in solving the 1st problem written above). However, this does not mean that other features are not wanted that are required to solve all the 3 problems above.
