- Type about:config in adressbar of Firefox.
- Type safebrowsing in filterbar. Now Change the following Values
- browser.safebrowsing.enabled FALSE
- browser.safebrowsing.malware.enabled FALSE
- browser.safebrowsing.remoteLookups FALSE
Thats all and the feature will be disabled now. Even though, My advice is not to disable it as Disabling it may increase the risk of getting infected.
And Firefox keeps phoning home for updates and turning it off in the options doesn’t stop it. Here’s a solution:
You can manually reset the Software Update feature by closing your Mozilla application and deleting the “updates” folder and the two files “active-update.xml” and “updates.xml”, which can be found in one of these locations (using Firefox as an example):
- Windows XP/2000: C:\Documents and Settings\<username>\Local Settings\Application Data\Mozilla\Firefox\Mozilla Firefox
- Windows 7/Vista: C:\Users\<username>\AppData\Local\Mozilla\Firefox\Mozilla Firefox
