javascript - 系统JS : WARNING error running cfx run once updated to Firefox v25

Question

我正在尝试测试我正在开发的附加组件，该附加组件在我升级到 Firefox v25 之前一直有效。然后我开始收到以下错误:

System JS : WARNING chrome://browser/content/tabbrowser.xml:2635
        function loadURI does not always return a value
System JS : WARNING chrome://browser/content/tabbrowser.xml:2655
        function loadURIWithFlags does not always return a value

然后当我点击任何东西时出现过多的 js 错误。我运行了 cfx testall 并遇到了一堆错误。然后我下载了全新安装，但在运行 cfx testall 时仍然出现错误。

我运行的最后一个 cfx testall 的完整结果:http://www.otherrealm.org/cfxErrorMessages.txt整个错误跟踪太长以适应一个 stackoverflow 问题，但这是其中的一部分:

Answer 1

Javascript 严格警告，包括您提供的 tabbrowser 警告，可以安全地忽略，来自 Firefox 代码本身，只是因为 how the SDK sets up javascript.options.strict 而出现。 .

我测试了some stuff from github使用 SDK 1.14，虽然确实有很多严格的警告(以及一些可以忽略的不相关的 Firefox 错误)，但总体上似乎可以正常工作。

如果您遇到任何无法正常工作的具体问题，请修改您的问题。

testall 错误是预期的:您正在针对 Firefox Release 运行 SDK master，它尚不支持 function* 也不支持它有 bug 910517然而(collectReports 东西)。同样，这没什么好担心的，因为将使用 Firefox 附带的 SDK 库版本，除非您明确告诉 cfx 否则(无论如何都不支持)。
