+Efektīvs reklāmu bloķētājs: nepārslogo procesoru un atmiņu, un var ielādēt un pielietot tūkstošiem filtru vairāk nekā citi populāri blokatori.
+
+Ilustrēts apskats par tā efektivitāti: https://github.com/gorhill/uBlock/wiki/%C2%B5Block-vs.-ABP :-Efficiency-compared
+
+Izmantošana: Uzspiediet lielo pogu uznirstošajā logā, lai izslēgtu/ieslēgtu µBlock pašreizējā web vietā. Šī poga attiecas tikai uz pašreizējo tīmekļa vietni.
+
+***
+
+Elastīgs, tas ir vairāk nekā "reklāmu bloķētājs": tas var arī lasīt un izveidot filtrus no host failiem.
+
+Pēc noklusējuma, šos filtru sarakstus ielādē un izpilda:
+
+-EasyList
+- Peter Lowe’s Ad server list
+- EasyPrivacy
+- Malware domains
+- Long-lived malware domains
+- Malware Domains List
+
+Ja vēlaties, ir pieejami daudz vairāk sarakstu, lai Jūs varētu izvēlēties:
+
+- Fanboy’s Enhanced Tracking List
+- Dan Pollock’s hosts file
+- hpHosts’s Ad and tracking servers
+- MVPS HOSTS
+- Spam404
+- Un daudzi citi
+
+Protams, jo vairāk papildus filtri tiks lietoti, jo lielāks atmiņas patēriņš. Tomēr pat pēc tam, kad pievienoti Fanboy divi papildu saraksti, hpHosts reklāmas un sekošanas serveriem, µBlock patērē mazāku atmiņas daudzumu, nekā citi populāri blokatori.
+
+Arī jāapzinās, ka izvēloties dažus no šiem papildus sarakstiem, tas var izraisīt lielāku iespējamību, ka tīmekļa vietne tiks nepareizi parādīta - īpaši sarakstos, kurus parasti izmanto kā hosts failu.
+
+***
+
+Bez filtru sarakstiem, šis paplašinājums nav nekas. Tātad, ja kādreiz vēlaties kādu atbalstīt, padomājiet par cilvēkiem, kas strādā, lai uzturētu filtru sarakstus, ko lietojat, tie ir pieejami lietošanai visiem par brīvu.
