Their new fangled update schedule is highly problematic.
I am using Ubuntu GNU/Linux.
Under the "Tools" menu, choose "Options," activate the "Advanced" section, then select the "Update" tab; you'll be presented with a myriad of options for disabling or controlling how the updates behave as shown in the screen shot I've included from Firefox v3.6.23 below for your convenience (it looks the same in Firefox v7.0.1, so I'm assuming it isn't any different in Firefox v6.anything).
What problems are you encountering with the update schedule, by the way?
Tools -> Options -> Advanced Choose stop checking updates or check Ask me what I want to do
You can set these prefs in about:config
to disable automatic updating:
app.update.auto - false
app.update.enabled - false
app.update.silent - false
Got these from https://support.mozilla.org/en-US/questions/1001740
When installing Firefox, choose the customize radio button instead of default installation may be in 2nd or 3rd screen of the installation wizard and uncheck
Mozilla/Firefox maintenance service
. It will certainly work.
plus:
app.update.auto - false
app.update.enabled - false
app.update.silent - false
in firefox configuration
plus:
Disable auto update from:
Tools->Options->Advanced->Update->
select never check for update
Good luck
