I normally default to SearxNG search engine but sometimes use swisscows.com.
For some reason, if I let FOSS browser remove the tracker portion of the search, it will no longer work. If I allow the tracker to be used, it works every time. I have tried multiple Searx engine instances, and they all seem to have the same issue.
It sounds like maybe it’s removing the actual search query part of the URL?
Because swisscows.com has no trackers in the URLs for searching or clicking on results.
