Error fix Rated 4 out of 5 stars

For those who get error "CSS Usage Warning: storage not yet available" this is the solution. Find file C:\Users\YOUR-WINDOWS-PROFILE-NAME\AppData\Roaming\Mozilla\Firefox\Profiles\km6qm46h.default\extensions\csscoverage@spaghetticoder.org\chrome\content\cssusage\CssUsage.js on your computer

and change line ~60 from

// return Application.extensions.get("csscoverage@spaghetticoder.org").storage;

to

return Application.extensions.get("csscoverage@spaghetticoder.org").storage;

This review is for a previous version of the add-on (0.2.4).
