Hello,
I am looking for a way to get rid of the following popup:
"Firefox can be updated to a newer version"
I have deactivated the auto updates and possibillity to update in general as i've seen in other posts.
But i can't find the proper setting for this not to show up.
You can set an enterprise policy to do it. Create a distribution folder within FirefoxPortable\App\Firefox and in there create a policies.json file. Within it, add this:
Save it and copy that distribution folder to FirefoxPortable\App\Firefox64 as well. When you start Firefox, type about:policies in the address bar to ensure it is working.
Sometimes, the impossible can become possible, if you're awesome!
