Who Uses Greasemonkey?

As Johan and I begin to take over development of Greasemonkey, one of the important questions we need to answer is: which platforms should we support? We can inform this decision with some of the usage statistics that Mozilla Add-Ons gathers.

The statistics page for Greasemonkey is visible to everyone. The raw data is even available for download. But it can be hard to read, due to the level of detail and formatting that is applied. So, I've taken the time to analyze it carefully. The first interesting thing that we can see is the usage trends over time:

(Looks like Mozilla had a reporting issue around May of 2009.)

I've also made a pie-graph of app usage, for the average values of the past 4 weeks:

That pie chart represents these numbers:

AppUsersPercent
Firefox/<=1.05980.02%
Firefox/1.555020.21%
Firefox/2.01139214.31%
Firefox/3.0147058455.70%
Firefox/>=3.5104909239.74%
Other4460.02%


So, let's say first off: we know this is a bad measurement. There's (almost) no "other" because there's no official support for other platforms, so only third party alterations make this usage possible. Thus, this data doesn't help us answer (i.e.) "Should we support Flock?" or "Should we support SongBird?".

It does let us know a little bit about what versions of Firefox we should support. All of 1.0 and 1.5 make up only 0.23% of the user base. Firefox 3.0 and 3.5 make up 95.44% of the user base. Firefox 2, however, makes up 4.31% of the user base. That's a much harder call.

There is no reason other than inertia to use Firefox 2.0. Greasemonkey is for power users who can be expected to upgrade.

"Greasemonkey is for power users who can be expected to upgrade."

Exactly my thoughts. Don't support older versions, I say. Focus on fixing all those bugs and requests instead.

I say drop FF2 support, and we still cover ~95% of the users, and they still have older versions to use, that's a decent situation.

I absolutely love this addon :)I've updated my firefox to the current 3.5.3 version but greasemonkey doesn't seem to work :( Am I missing something?

Incompatible Extension
Greasemonkey 0.8.20090123.1 could not be installed because it is not compatible with Firefox 3.5.3.

(this is the error I get. re above comment)

Could it be possible that User Agents Switching could possibly screw the results up?

Some people pass the responsibility to expert writers because they miss the ability to compose a respectable paper about Greasemonkey in order that the reason why students need to use plagiarism detection, but such customers like writer don't do that. Thank you very much for the article

Chrome will never be the future unless it implements an addon system, fixes it's tab system, stability issues, and makes a better theme system among others, but why wait on Chrome when we have a great browser already? Chrome may end up being the future, but not until it catches up to the present. Hey, at least it beats Internet Failsplorer.
