Any idea of firefox's max URL length?

The Google Chart API does not limit the number of datapoints. However the browsers have a maximal URL length, for example Internet Explorer has a maximal URL length of 2083 characters.

I suggest to reduce the length of the URL by using a different encoding for the data. Currently you use 5 bytes per datapoint: 70.1, You can reduce this to 3 bytes by removing the last digit (and the dot), however you loose precision then. The extended encoding (http://code.google.com/apis/chart/#extended) only uses 2 bytes per datapoint and has enough precision.

Also you can try to reduce the number of datapoint, eg by only using every second or third datapoint.
