Is it possible for hackers to access my Firefox browsers login storage through the internet? For instance if I visit a malicious website?
The answer, according to me would be yes in cases such as:
- Website is able to execute code on your machine and exploit a vulnerability. In general if an attacker can execute code on your machine it doesn't remain your (secure) machine anymore.
- You are fooled into entering password on the wrong website using the browser password store.
- Finally, vulnerabilities in the browsers password store mechanism itself will lead to access of stored credentials. Refer to:
Hope this helps.
