^DJIA Rated 4 out of 5 stars
This is, by far, the superior stock ticker for Firefox. However, I do not completely agree with the developer's reply on September 9. If this is a Yahoo! Finance issue, why do I get the same error message that ^DJIA can't be verified when I switch to Google Finance? Also, the "FoxStocks" add-on, which is a competitors plug-in, successfully displays the ^DJIA ticker. I believe the issue is in the StockFox code.This review is for a previous version of the add-on (1.3).
^DJI is a yahoo-only symbol. For Google Finance I believe it is .DJI. StockFox is using the Yahoo! Finance web APIs to retrieve data. Dow Jones no longer supplies Yahoo with this information via this web API mechanism, which Yahoo! verified to me. I am not sure how FoxStocks work, but they may be able to retrieve information via screen-scraping, which I would rather not do as it is too brittle. As an aside, I can assure you that the StockFox code is a beautiful, bug-free masterpiece, so I resent the implication :) Thanks. Tom
