How to disable Firefox add-ons update check on start

Question

I have a problem and I hope you have the answer.
Here it is:

I start Firefox (Linux) via command line using a cron-job. When there is no update for the add-ons, it start up normally, then I can tell it what to do. However if there is an update for an add-on, then it ask whether to take that update or not. I don't have the ability to detect the pop up window and choose no.

So, how can I disable all question upon startup of Firefox.
Qustions like:

Do you want to update add-ons?
Do you want to upgrade Firefox?
Do you want to open previous tabs or new session?

I pretty much would like to keep my version of Firefox the way its and no have any questions asked.

When I start Firefox, I would like to have it start nice and clean without any questions.

Answer 1

Unless the linux version is very different, under settings > advanced > updates, there are settings you can disable, that are concerned with the automatic searching for updates for firefoxx and its add ons.

In "about:config" you can set "Browser.sessionstore.enabled" to false, in which case firefox will not restore your tab state after a crashed browsing session.

Answer 2

Depending on what functionality you need while FF runs, you may want to look into the safe-mode switch when starting Firefox:

/path/to/firefox -safe-mode

Answer 3

All those options should be in the standard settings of the application. From the command line, safe mode is what you want to look into.
