With ABP disabled, all works like before under this default profile.Ģ. I deleted storage.js (was 39MB, now it's 13MB), patterns.ini, patterns-backup5.ini, then restored the filter backup (like suggested in ABP forum).Not as slow or blocking as the default Firefox profile, but a lot slower than before. I created an empty profile, made sure Firefox (last version) works fine, then as soon as I installed ABP (with default filters, so only EasyList), it went downhill, everything was slow.With ABP disabled, all works like before under this default profile.The sites with more content than usual work as before (Mozilla Firefox 52 or 2-3 weeks ago) Clicking on links or videos is also slow until mouse is ready. While Netflix homepage is unusable, other sites are affected by slowness (Twitter, YouTube, etc) and it's very slow to scroll in them. Images load slow, everything lags, whole browser becomes blocked until I close the tab. Filters: Adblock Warning Removal List, EasyList, EasyPrivacy, Malware Domains
