What steps will reproduce the problem? 1. Install hybridfox-1.6.000083.xpi 2. Install Firefox 5 Update 3. Open Hybridfox

What is the expected output? What do you see instead?

Expected: Listing of currently running instances. Actual: Popup with the following error message:

An error occurred while calling DescribeRegions
TypeError: activeEndpointType is undefined

What version of the product are you using? On what operating system?

hybridfox-1.6.000083.xpi Mac OS X 10.6.7

Please provide any additional information below.

The hybridfox xpi file is from Issue 80: http://code.google.com/p/hybridfox/issues/detail?id=80

Clicking on any of the items near the top of the window (Instances, Images, Keypairs, ...) results in the same error.

click on the regions dialog your endpoint type should be undefined , set it to your preferred type and check it after reloading.

The regions dropdown shows us-east-1 from EC2 like it did while using an older hybridfox. I tried changing it to other regions, but nothing happens. I also tried opening the regions dialog, it shows a list of endpoint names and endpoint urls I have set up before, but upon closing the dialog, the popup error appears again.

I cant get you, but still if you have an error go to about:config remove ec2ui.endpoints,and restart hybridfox. This should work.

That worked nicely, thanks!

For reference, here are the values of ec2ui.endpoints before and after the reset (one IP blocked out):

Original: ({'us-east-1':({'name':'us-east-1','url':'https://ec2.us-east-1.amazonaws.com'}),'eu-west-1':({'name':'eu-west-1','url':'https://ec2.eu-west-1.amazonaws.com'}),'us-west-1':({'name':'us-west-1','url':'https://us-west-1.ec2.amazonaws.com'}),'ap-southeast-1':({'name':'ap-southeast-1','url':'https://ec2.ap-southeast-1.amazonaws.com'}),'Private Cloud':({'name':'Private Cloud','url':'http://xxx.xxx.xxx.xxx/services/Eucalyptus'}),'ap-northeast-1':({'name':'ap-northeast-1','url':'https://ec2.ap-northeast-1.amazonaws.com'})})

Reset: ({'us-east-1':({'name':'us-east-1','type':'ec2','url':'https://us-east-1.ec2.amazonaws.com'}),'us-west-1':({'name':'us-west-1','type':'ec2','url':'https://us-west-1.ec2.amazonaws.com'}),'eu-west-1':({'name':'eu-west-1','type':'ec2','url':'https://eu-west-1.ec2.amazonaws.com'}),'ap-southeast-1':({'name':'ap-southeast-1','type':'ec2','url':'https://ec2.ap-southeast-1.amazonaws.com'}),'ap-northeast-1':({'name':'ap-northeast-1','type':'ec2','url':'https://ec2.ap-northeast-1.amazonaws.com'}),'ECC':({'name':'ECC','type':'euca','url':'http://ecc.eucalyptus.com'})})

this just happened to me using the latest Hybridfox 1.7000177

clearing the endpoints in about:config fixed it - many thanks for posting the solution
