My favorite product is add-on and Firefox android because it help us alot in each field like if we want to take snap shot of screen it is not possible in all android phone , but using using add-on one can easily grab the whole screen or half according to his wish.
And let me give you another example while reading a new blog or page it hard to copy down the entire document and most devices aren’t capable of copying thing but tools can help you to save the whole page and one can read it whenever he/she gets free time .
These add-ons should be highlighted to maximum extent so that one can find easy way to finish the work as soon as possible in this fast and busy life
I believe in order to stay alive in this competitive world we should start developing these tools.
