If you have automatic updates enabled in Firefox, the browser will check for updates periodically by querying a Mozilla server.
The frequency of checks depends on the release channel of Firefox with Nightly being updated the most and stable the least.
The reason for that is simple: Nightly updates are published more often than other updates of the Firefox web browser while stable updates get only released occasionally (usually once or twice a release cycle).
Related to that is the notification interval which Firefox uses to notify the user of new updates.
In case you are wondering, here are the default update frequencies for all Firefox channels. The value is listed in seconds by default and I have taken the liberty to add the time in hours as well.
The values are taken from Firefox 29 Stable, Firefox 30 Beta, Firefox 31 Aurora and Firefox 32 Nightly.

Change the update check frequency
It is possible to change the frequency in which the browser checks for updates. This can be useful if you want it to check more frequently for updates, by reducing the interval, or to configure it to check less often for updates.
Here is what you need to do:
You can reset the value at any time with a right-click on the preference and the selection of reset from the menu.
Change the update notification interval
You can change the notification interval for new updates as well. Repeat the first two steps from above and do the following afterwards:
You can reset the value at any time with a right-click and the selection of reset from the context menu.

Once a week for aurora as of FF32 ? Are you sure it is not for stable or… ? As a test version, I would expect it to prompt faster, not slower than beta/stable.
No it is once week. According to the bug report, this is for developers mainly who are irritated by the frequency of updates.
Which bug please?

Very interesting, thks
Won’t these modifications erased by the following update ?
No they won’t be reset.
What I would like to know is how to get it to stop updating without my consent. This occurs no matter how often I change the setting to notify me but do not update, or even if I tell FF to never check for updates. My profile is NOT read only, and all my other settings work just fine. It is so annoying, it is one of the reasons that I use Palemoon now. I still have Fitefox installed, but the day of having it that way are close to being over.
What is the ideal setting for the search browser.search.update.interval? I mean what is the typical file size that it downloads for the index? That would tell me what kind of a hit in performance I am taking. Also how often make sense? Is google or duckduckgo updating their search index constantly or just once per day? I would like to get the most current results but I don’t want to take a huge hit in performance for it.
Thank you for any comments/feedback you could offer.
