How does Chrome/Firefox make sure add-ons are safe? Do they have any protection against a malicious add-on?
How much access can add-ons have? Can they access internet history or maybe even cookies and such and send them to a server? Do I need to worry about this?
I do have Kaspersky and Kaspersky add-ons but I still wonder should I still worry about add-ons? Considering there is nothing I can do to make sure some add-ons are malicious or not even if they still have an OK reputation.
EDIT: bonus question, if an addon says it can read the data on websites you visit, does it mean it can know which websites I visit and technically can send them to a server and basically record my history this way ? (considering many adblockers and such addons have this permission)
