changed font to sans sherif: Solves #676

[shikhar-scs]

The font as marked out by @johngruen in #676 was different (Fira sans) and it has now been set to Sans sherif as required.

@sevaan Please have a look at this. Do I need to change anything else too.

[sevaan]

It's sans-serif, not sans sherif.

Plus, I believe there is some alternate font information missing (redundancies, etc). I can see it when I view other text on the site in inspector. @dannycoates might be able to provide the missing info.

ohk I'll have a look and revert back here

@sevaan

what I've noticed is that 'SF Pro Text', sans-serif and 'Segoe UI', 'SF Pro Text', sans-serif have been used alternatively in the main.css file and so for the time being I've used 'SF Pro Text', sans-serif. However, if the latter is required to be used then I'll do that accordingly.
Also, once the PR gets reviewed, I'll squash my commits too :)

@sevaan @dannycoates @johngruen do you mind giving a review?

[dannycoates]

This should be:

font-family: 'Fira Sans', 'segoe ui', sans-serif;

and also applied to #dl-firefox, #update-firefox

[shikhar-scs]

font-family: 'Fira Sans', 'segoe ui', sans-serif;
and also applied to #dl-firefox, #update-firefox

I'll do that rightaway
