Firefox update by command

Hello,

I have a question about updating Firefox on Windows. Is there a command that tells the MozillaMaintenance Service (or Updater.exe) to check for updates and if there is a new update, to install it?

When Firefox is started, Firefox also checks for updates automatically or when the user goes to Help -> About Firefox. And that's exactly what I want to start with just one command. Is that possible?

Thanks a lot.

You can only update Firefox from within a browser that is running. Otherwise you would have to download the corect MAR file and apply the update manually yourself.

wiki.mozilla.org/Software_Update wiki.mozilla.org/Software_Update:Manually_Installing_a_MAR_file wiki.mozilla.org/Software_Update:updates.xml_Format

You need these three files in the updates\0 folder to update Firefox via a MAR file:

update.mar (renamed update partial/complete.mar) update.status: pending + linefeed (0x0A) (use this data URI: data:text/plain,pending%0A) update.version: xx.xx.xx (version to update to, e.g. 50.1.0) In my view there is no any commands for upadte. Thank you.
