Cannot attach file with Firefox

[Erkki Lepre]

Last weekend we upgraded our Jira from 4.1 to 4.4.4. After that we have been unable to upload attachments when using the Firefox browser. (We have tried FF versions 4, 9 and 10). The error we get is Cannot attach file <file name="">: Unable to communicate with JIRA., where the <file name=""> is the name of the file. The problem is reproducable both with Windows and Linux clients. With IE and Chrome there have been no problems.

We have seen the case https://jira.atlassian.com/browse/JRA-24166 and tried removing the useHttpOnly=true attribute, but it didn't help, so it seems to be a different case.

We are running jdk1.7.0_02 on the server.

Same issue here (Jira 4.4.3). It is working with fine with Jira 5.2.3

Do you get the same error with jdk 1.6? I'm asking since 1.7 is not yet supported officially. http://confluence.atlassian.com/display/JIRA/Supported+Platforms

[Erkki Lepre]

Yes, the same happens with jdk1.6.
