64-bit Firefox crashes with Citrix's XenApp VM

64-bit Firefox hangs or crashes on Citrix XenApp 7.13 VDA because Citrix XenApp’s API hooks are not compatible with 64-bit Firefox. Here are some solutions you can try.

How can I fix the problem?

You can work around the problem by disabling XenApp’s API hooks for Firefox executable filenames “firefox.exe” and “plugin-container.exe”. See this Citrix support article for instructions.

What is the long term solution?

Citrix has fixed this crash in XenApp version 7.14 (Citrix issue #LC6982).
