Font info may display wrongly on different window widths Rated 4 out of 5 stars

Thanks for the extension. It is very useful. However I encounter a bug when viewing a Chinese passage.

I see this bug on different Chinese characters if I set different window widths.

This review is for a previous version of the add-on (0.1.1-signed). 

Thanks for reporting this - I can reproduce this problem, and will try to look into it.

Follow-up: this is due to a bug in the API used to get font information for a selected range of text; see https://bugzilla.mozilla.org/show_bug.cgi?id=695639. Once that is fixed, the results should be consistently accurate.
