Best of its kind Rated 5 out of 5 stars

Greasemonkey allows to run small bits of JavaScript that change the way webpages look and function. The possibilities here are endless. I use it to automatically fill the registration form and make the bots for online games. No decent replacement.

Can't update from url? Rated 3 out of 5 stars

Great addon, but can't find anyway to update js from url. Tampermonkey has this function already.

RAM usage Rated 2 out of 5 stars

Big problem with RAM usage, I don't know why but without greasemonkey ff usually consumes about 500mb ram. In some cases the usage can be over 1,2GB RAM just because of Greasemonkey addon.

If this is truly happening, it must be due to a script you have installed. Greasemonkey does not do this on its own.

Interesting but ... Rated 2 out of 5 stars

Interesting but their privacy policy definitely made me uncomfortable enough to uninstall ...

Good idea Rated 5 out of 5 stars

Really good implementation. Too bad the most user-friendly userscript-site has gone down. Alternatives are less user friendly.

Good extension Rated 5 out of 5 stars

It's simplicity is the best. Don't need all that fancy options TamperMonkey provides. Wish it would be easier to debug userscripts though.
