Go into your uBlock settings and purge the cache and update your filters, that should fix it, filters do usually keep up to date with YouTube but uBlock stores the old ones cached.

As per the arkenfox wiki, you should not touch user.js but rather in user-overrides.js add (or create it) the following:
/* override recipe: enable session restore ***/ user_pref("browser.startup.page", 3); // 0102 // user_pref("browser.privatebrowsing.autostart", false); // 0110 required if you had it set as true // user_pref("browser.sessionstore.privacy_level", 0); // 1003 optional to restore cookies/formdata user_pref("privacy.clearOnShutdown.history", false); // 2811 // user_pref("privacy.cpd.history", false); // 2820 optional to match when you use Ctrl-Shift-Del
See info on overrides and the recipe to enable session restore
uBlock Origin has cookie/popups filters that you can enable in its settings that work pretty well
