Add-on summary

Supports most standard operations. Do note that it struggles with floating point operations so sin(3.1415926535897932) will be a really really really small number instead of zero.

The only permissions this addon has is to read the omnibox whenever you type m@. You are free to audit the source code at the GitHub link below.
