How to prevent Firefox from updating and disabling plugins

Postby admin » Fri May 26, 2017 6:37 am

To prevent FireFox from updating and potentially disable add ons, running all your plugins or putting them out of work, do the following:

From the FF options menu:

Select the “Menu” Menu Button button in the upper-right corner, then choose “Options“.
Select “Advanced“.
Choose the “Update” tab.
Select one of the following options as desired:
Automatically install updates
Check for updates, but let me choose whether to install them
Never check for updates
Check or uncheck the “Use a background service to install updates” option as desired.

From about:config Menu

Type “about:config” in the address bar, then press “Enter“.
Search for the “” setting.
Double-click the “” option to toggle the setting. If set to “true“, automatic updates are enabled. If set to “false“, automatic updates are disabled.

Via prefs.js file

Close Firefox.
Navigate to the following location based on your operating system.
Windows XP/Vista/7/8/10 – “%APPDATA%\Mozilla\“
Unix/Linux – “~/.mozilla/“
Mac OS X – “~/Library/Mozilla/” or “~/Library/Application Support/“
Open the “Profiles” folder.
Open the folder that represents the profile you would like to edit. The name of the folder will vary. It is usually a bunch of characters, followed by “.default”.
Open the prefs.js file with a text editor like Notepad.
Look for a line that contains app.update.enabled. If it doesn’t exist, add a line for it in the file and set it as desired using these examples:
user_pref("app.update.enabled", true); = Automatic updates enabled
user_pref("app.update.enabled", false); = Automatic updates disabled
