Some people might be interested to know what the requirements are to be included as a search engine in Privacy Browser.
- The search engine must produce usable results.
Some search engines allow users to alter the default functionality, like the theme or pornography filtration levels, which usually requires cookies. This behavior seem reasonable to me, but default functionality of the website, like advancing pages in the search results, must work without cookies.
The current list of search engines is as follows.
Monocles is the current default search engine, although there are things I don’t like about them, and I would be happy to switch if I could find something better.
Monocles is a newcomer to the list, and is quite good. I would like to make it the default search engine. My biggest concern is that, as a (highly) customized Searx instance, it will fall prey to the same rate limiting issues that have dogged other Searx instances.
Metager is quite good, but with default settings on Privacy Browser it includes ads that use a URL redirect to track users. I don’t mind looking at ads, but I do mind when they look back at me. I would be very reticent to make a search engine the default if it returns results that use tracking URL redirects when I have at least one option that does not do so.
DuckDuckGo used to be the default search engine, but it was supplanted when their privacy chops started going down hill.
Users can add whatever search engine they like using the custom option.
