Significantly affected performance after installing, for example I can't even smoothly switch between tabs using Ctrl+PageUp/PageDown when this addon is enabled.

Edit: I'm just looking for an addon that blocking JavaScript from certain sites, it seems this addon is overweight for me.

This is the best recommendation i received and i would recommend it other people to use it.

it made slow websites faster and blocked many trackers

invadente , è vero che blocca la pubblicità soprattutto su youtube ma poi salta fuori ad ogni accesso e invita a passare alla versione a pagamento, inoltre ache dopo averlo disinstallato si ripresenta e si deve eliminare anche l'icona x liberarsene definitivamente

llevo años usándola, es muy buena
