A short while ago, I suddenly noticed that google streetview stopped working.

There was no error messages, and the page would just continue to show the google map.

After some searching I discovered that streetview uses flash, and a recent change by google has caused my browsers flash blocker (flashblock) to stop streetview.

Luckily, the solution is very simple:

go to firefox tools -> add-ons -> extensions -> flashblock -> options -> whitelist

just add the following to the whitelist:

http://maps.google.com/

http://maps.google.com.au/

http://maps.google.co.uk/

and any other country code that google has used to streetmap.
