I was using Firefox 3.5.x - don’t remember the version - and at one point noticed Google Street View didn’t work correctly. I was able to drag the orange figure onto the map, and then there it would stand, like a human traffic cone, and nothing happened. No photos.
So I first installed 3.6.6, figuring there was a problem with Firefox that had been fixed in a more recent version. No success.
Then I googled “street view doesn’t work in firefox” and found this site. They suggested upgrading my flash player, which I did. The installation completed 100%, but no success with Street View.Out of ideas, I switched to IE and tried Street View. It told me that the flash player was outdated and needed an update, so I upgraded here, too. And ta-dah, it worked!
So, back to Firefox: I went to the Flash download page again and found instructions for downloading and installing with Firefox. I added www.adobe.com to the list of sites that are allowed to install add-ons (Tools/Options/Security) and for good measure to the list of sites that are allowed to generate Popups (Tools/Options/Applications). The installation looked a bit different, but it displayed the same message of a successful installation and again did nothing to fix Street View.
Aha, I thought, I bet it’s my Flashblock. I disabled it, restarted Firefox, and ta-dah, Street View works! I don’t know who (Google, Adobe, Mozilla, or the Flashblock programmers) is to blame, but Flashblock 1.5.13 seems not to work right with the current Street View and Firefox and Flash 10.1.
So, although I liked it (especially for youtube playback control), I’m turning Flashblock off for now, but if I find I don’t use Street View enough, and the instant playback on youtube bugs me enough, I’ll turn it back on. I wish they’d fix this situation, though, so that for Street View I’d get the same “play” symbol Flashblock usually displays.
