I'm willing to install FishEye but I can't find any download available on Atlassian's website . The download archives are also unavailable . Same problem for Jira and Confluence.
perhaps you have a FireFox extension which is causing problems?
You can use this direct link to download the latest version of FishEye: http://www.atlassian.com/software/fisheye/downloads/binary/fisheye-2.7.6.zip
