I don’t like Firefox constantly updating the version or the Add-ons all by itself at startup without my knowledge. You can enable or disable automatic updates in Firefox with these steps.
From Firefox Menus
- Select the “Menu”
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.
button in the upper-right corner, then choose “Options“.From about:config Menu
- Type “about:config” in the address bar, then press “Enter“.
- Search for the “app.update.auto” setting.
- Double-click the “app.update.auto” 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 enableduser_pref("app.update.enabled", false);= Automatic updates disabled
Go to windows RUN–>services.msc–>find mozilla maintenance services–>right click —>properties—>disable services.
Find Mozilla folder in program files, find *update* search criteria and rename all update.ini files.
Thank you
I suggest to uninstall Mozilla Maintenance Service. This service updates you firefox automatically, even if you disabled.
Ok. The missing part is “FireFox v42.0 installation folder” with arrow signs at two ends.
I’m still keeping FireFox v42.0, which is the last version allowing unverified add-ons. But it constantly gets auto updated to version 43.0.1.
I’ve done all the settings suggested here above. But once I open any item in the Help menu. Auto update is triggered regardlessly.
So, after auto update has downloaded all its files, I have to do the following to destroy the update:
(1)
While the old version of FireFox is still in session, clear the cache because auto update stores some files in it.
(2)
Before the next time FireFox is opened, delete these folders, which have been generated by auto update:
\updated
%LOCALAPPDATA%\Mozilla\updates
Even after disabling the auto updates, Firefox gets updated automatically.
