I have seen someone posting a link to the new browser game from mozilla using HTML5. Its a short game that can be finished in a couple of minutes. The game  style is patterned MMORPG, with other online players inside the browser. You can interact to each of the online players or even talk to them. The browser game link is at Browser Quest game. The game is actually similar to the Diablo 3 beta where the ending gets to defeat King Leoric or the Skeleton King. Nah, purely coincidental…

There are 2 more achievements in the game which are hidden or with no clues on how to get them. If you are looking on how to solve the last two hidden achievements in the game, here’s how. These last two achievements are called “For Science” and “Rickroll’d”. They are actually very easy to get.

Here is the screen shoot of the last two the quests unlocked.

For Science Mozilla Browser Quest Hidden Achievement

There is a place down the town to the right where you can see portals. Just get into the portal and wait for the cake to come out and grab it. See the images on how to do it on your own.

Rickroll’d Mozilla Browser Quest Hidden Achievement

The other hidden achievement is located just above town in the forest where are are ogres guarding the cave. Its a bit tricky and confusing so remembering which door you entered is important. You could test each door until you find the place where there is Rick singing. Just click on him and get the achievement.

Tip: There is a trick in getting into Rick easily. When you get into the confusing doors, always select the leftmost door, May it be located on top or at the bottom and even if you came from that door.

Just in case you were wondering who Rick is, we’ll here is the source of the real Rick
