setTimeOut Did Not Function Correctly in Greasemonkey 0.9.19 / Firefox 12

 [Updated] Greasemonkey version 0.9.20 beta released, check out my latest post

Today I got lot of complains from players whom using MouseHunt AutoBot or Fish Wrangler AutoBot that the script stop working in Firefox. The problem they are facing is the timer only manage to run half way (maybe 2 – 3 seconds) then it stop. While the other browsers can run the script without any problem at all. This is because Greasemonkey just push out their latest update 0.9.19 to your Firefox browser without you knowing and this version screw up the setTimeOut javascript function which is used to run the timer in the script. In version 0.9.19, they claim to have a better version of setTimeOut function wrapper, but in fact it screw thing up. Maybe you wondering why the in game timer run without any problem but that is because they are using the actual javascript engine offer in Firefox and not though Greasemonkey like user script.

What you can do then? For the mean time, use other browsers like Opera or Chrome until there is another update by Greasemonkey that fix this problem. Or you still insist want to use Firefox? Then you will need to downgrade your Greasemonkey version. How to do it? First, uninstall your Greasemonkey add-on in Firefox then restart your Firefox. Then go to install version 0.9.18 instead. you might need to reinstall the user script too. Please note that your friendly Firefox will try to help you update the Greasemonkey to the latest version if you restart Firefox.

Let’s keep our fingers cross that Greasemonkey release an update to fix this mess. I will update you all when a better solution found.

Easy Way To Add User Script in Firefox

Ever downloaded a user script from website other than and figuring how to install it into Firefox? Ever write your own user script and have problem install it into Firefox?

I do have those problem when I first installed Greasemonkey and download some user script to try. The Greasemoneky Installation dialog usually won’t pop up if I download any user script from website other than Every time I drag and drop a user script file into Firefox, the Greasemonkey will definably pop up a install button on top of the page, but the button never work out for me.

After spending some time playing with user script, I finally discover a better way of install a user script into Firefox instead of click on the New User Script menu button and paste all code into the new created script. It is nothing new or special, but the menu button is hidden instead of disable when no user script is open in Firefox. This cause many users include me did not realize the existent of the button at all.

To install a user script after download and save at local disk, just drag and drop the file into Firefox, then go to Tools > Greasemoneky > Install User Script. If you did not found the Install User Script button, this is because you are currently not viewing the tab that contain the user script file open in Firefox.

After click on the Install User Script button, the Greasemonkey Installation dialog will pop up. Click on Install button after the countdown end and the user script will be installed into Firefox.

I’m very curious why the button is hidden instead of disable. It just doesn’t make sense to me. The install button pop up on top of the page every time user drop a user script into Firefox never work, a bug? Anyway, I never know the answer unless I go and ask the developer, which I’m not going to do.
