I have to be honest and say I don't know. The PFX was exports with the entire chain, and the XPI was signed using XPISigner (also tried Key Manager plugin) and in both cases the XPI only installed on the signing machine. Other machines received the -260 error.
Interestingly, the XPI installed flawlessly in Firefox 4 on all machines. It appears that this problem only occurs in Firefox 3.6. How do I validate that the chain is correctly added to the XPI, and what software should I be signing with? -- dev-tech-crypto mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-crypto
