Firefox – How to Prevent Firefox Sync on Startup

firefoxfirefox-sync

In Firefox, I have a master password setup for my passwords. I also sync my passwords (and bookmarks, extensions and settings) using Firefox sync.

The annoying thing is that when I start up Firefox, it will always ask for my master password after a few seconds. So when I start up Firefox and type a web address or search query, I get interrupted by the password dialog popping up while I'm typing. I want to get around this because it is annoying me so much.

Questions:

  1. Can I make Firefox sync manually?
  2. Alternatively can I make Firefox sync only when I have to enter a password somewhere?
  3. Alternatively can I enter a delay value somewhere in about:config between starting up Firefox and running Firefox sync?

Best Answer

I asked the same question on Mozilla Support and got very useful answers. Answer that worked for me:

  • In about:config, create or modify Boolean services.sync.autoconnect and set it to false.

This may work in a future version of Firefox: Create or modify integer services.sync.autoconnectDelay and set it to a delay in seconds. Both settings did not exist for me yet in Firefox 28 beta.
