Wish I had seen this earlier. I was pulling my hair out trying to figure out why FF was suddenly so sluggish. It just happened to coincide with getting a new modem from Xfinity so thought that was somehow causing issues. It wasn't until I started disabling addons and got to MBG that everything returned to normal. I was prepared to just leave it disabled, but the above fix worked for me. At least if it happens again, I know where to start. I removed a star from my review for the hair pulling.

Пользуюсь расширением несколько лет. Около месяца назад расширение стало сильно тормозить загрузку страниц. Я сбросил настройки расширения к заводским. Это частично помогло. Загрузка страниц всё равно занимает в 2-3 раза больше времени при включенном расширении. Надеюсь, что проблема будет исправлена.

I've been using the extension for several years. About a month ago, the extension began to eriously slow down page loading. I reset the extension to factory settings. This partially helped. Page loading still takes 2-3 times longer with the extension enabled. Hope the problem gets fixed.

I was happy to see this on firefox but .....there is a big one, after install watch how nice it works then close the browser and later on all my performance and page loading went down hill just like i was 56kb/s .....

Offer most if not all options Bing and the other Browsers and MS Operating Systems and Servers.

Will update soon this review. Just installed Win 10 Professional and added to Mozzilla today 052123.

since last update slows firefox to a crawl

По моим наблюдениям - данное расширение даже после рекомендаций разработчика всё равно ощутимо замедляет браузер. Мне пришлось отказаться от использования этого расширения до момента его наилучшей оптимизации! Optimise the product better!

Since the last update my browser has become very very slow.
Web pages take up to 10 - 20 seconds to land.
I am a premium member of Malwarebytes for Windows Desktop.
If it does not run properly again by next week, I will have to look for an alternative.

For all the people that noticed a slow performmance in firefox loading webs (even if you can't load those webs) using the last versión of Malwarebytes' extension. The factory reset of this extension worked for me.

da un paio di giorni l'estensione mi bloccava tutti i browser su cui era installata con utilizzo spropositato della R.A.M.. solo disattivando l'estensione, son tornati a funzionare correttamente. così com'è ora è inutilizzabile. Se correggerete il problema la reinstallerò di nuovo visto che fa egregiamente il suo lavoro....

Aggiornamento: dopo aver seguito le istruzioni e aver resettato l'estensione, il problema sembra essere risolto. :)

Estava funcionando bem, mas a atualização mais recente está causando lentidão no carregamento das páginas. Depois que desativei a extensão, o problema acabou.

TURN OFF NOTIFICATIONS!!!!!!!!!!!!!!!!!!!!!!!!

Latest update with 113 stable and 115 nightly causes memory leak and pages either not loading or sluggish responses.

new update (May 11th 2023-FF 113.0 64 bit) is not allowing web pages to load (at all). Process of deduction of add-ons points to MB add-on as culprit.

Causes the whole browser to freeze up and crash in latest update (113.0), disabling it for now.
