How does the Addon update its Agent Strings to newer version of Brosers?

[gitgetgot]

Say, I downoaded this Addon in 2016 the first time.
After that, it updated within the FireFox Updateprocess for Addons. (I guess)
Will each update automaticly update the internal list of Agents for all Devices/OS?
Or does the User has to keep track of it?

I'm asking, because I still use FireFox 53.x but want to use a Agent for 57.x

Thank you.

@gitgetgot It doesn't auto-update since the developer has abandoned it. However, it's fairly easy to do and several of us have been keeping it alive by forking.

The best way to do it is: Get someone to send you HTTP HEADERS + Browser Info (From BrowserSpy.dk), then adapt this information to random-agent-spoofer/data/json/useragents.json

Then when you want to manually update it, just download the .xpi, open with Zip Utility, and drag + drop the new useragent.json into the appropriate folder. Re-Save and load in Firefox! Works well.
