Good but could be better Rated 4 out of 5 stars
I've been using StockFox for several months and I like it, but it is currently experiency a weirdness. Currently I'm using it with FF 3.6.13 under Linux. Overall, StockFox works quite well. But sometimes the display (ticker) at the bottom of the screen shows data that is several days old. Right now it is Thursday and the display is up to date; but several times today it has shown data from last Tuesday. I'm not sure what triggers this behavior, but I suspect it happens when FF has been idle for a while. Nevertheless, I'll keep using it because I like the features, and it's easy to bring up the "view stocks" display to see the date/time of the most recent update.
