Librewolf is too strict: for example, on slickdeals.net, a link there is like this https://slickdeals.net/click?pno=1011750&lno=1&sdtid=1783030... which leads me to https://www.kqzyfj.com/click-4485850-13804... with which ublock origin asks if I want to continue, I click on the Proceed button and I go the the page https://www.kqzyfj.com/click-4485850-13804171?url=https%253A...... and librewolf sometimes says that it's unable to connect (maybe librewolf doesn't like www.kqzyfj.com?).

LibreWolf is indeed very good.
