In the Wiki Monkey: "Greasemonkey will periodically check for new versions of the script by downloading them. "But what does it mean? Once a week? Twice an hour?
Does anyone have real numbers?
According to http://www.greasespot.net/2012/02/automatic-script-updates-come-to.html ,
By default, updates will be checked every seven days and automatically installed upon detection.
While Hellion points to the original post when automatic updates were released in early 2012, this has not been true for some time. It is not documented anywhere, so we need to do digging. Here you can see . Greasemonkey uses what looks like Firefox's built-in mechanism for validation and updating. It's hard to say when. From experience, I know that this is actually much less than every 7 days. It happened to me in an hour. Restarting firefox doesn't seem to trigger it, but the shortest I've seen was within an hour. Also, if we look for about:config in Firefox for update , we can find the specific setting that stands out. extensions.update.interval;86400 . Obviously, this means that the extension update interval is set to 86400 seconds (24 hours). Since Greasemonkey associates the update process with the firefox update process, I would think that is all. I will try to change this parameter to make sure that I am right. Later this weekend, when I finished with this document, I am working on it, I will let you know what I learn.
about:config
update
extensions.update.interval;86400
Although this question is about Greasemonkey, I will go ahead and say that Tampermonkey (Chrome) is much easier to check. Just click on the Tampbermonkey> Dashboard icon, then go to settings and you will see that the verification interval is set to 12 hours or whatever you change.
