I have just uploaded version 19.0 of the Rikaisama Firefox extension.
Download version 19.0 via SourceForge
What's New?
● Added word frequency information.
To enable, check the "Options -> Dictionaries -> Show frequency information" checkbox. It appears as a colored number to the right of all readings and conjugations.
Frequency of the highlighted word is shown in terms of the number of words that are more frequent than it + 1. So if a word has a frequency of 1563, it means that 1562 words are more frequent than it.
Frequency numbers are colored green-ish, yellow-ish, orange-ish, or pink-ish to indicate very common [1 - 5,000], common [5,001 - 10,000], uncommon [10,001 - 20,000], and rare [20,001 - infinity] words.
Screenshot:

Frequency information comes from analysis of 5000+ novels (via Japanese Text Analysis Tool). Frequency of words in other mediums, such as newspapers, might vary. Not all words have frequency information. It is possible for multiple words to have the same frequency if they where detected the same number of times in the frequency analysis.
● Added option to enable/disable the "no audio" clip.
See "Options -> General -> Enable the 'no audio' clip".
● Fixed bug that forced the pitch accent to be enabled in EPWING mode when the "Parse entry to add color, show pitch and enhance frequency" option was checked.
