Export licence issues: (with for instance Firefox ESR) ECCN & EAR is our documentation up to date

We have a WikiMo article 
Deployment:Deploying Firefox - 11 United States Export Control Information
https://wiki.mozilla.org/Deployment:Deploying_Firefox#United_States_Export_Control_Information
That article may well be out of date. The article certainly includes broken links.

I am prompted to ask this question because of a question an exporter asked in the Mozilla Sumo (Kitsune !! rollback) support forum: 

Home =>  Support Forum  =>   Firefox =>     EAR ECCN - Urgent Request
https://support.mozilla.org/questions/1159828

> Hi We are a company in the UK and we urgently require assistance to identify the Export Control Classification Number (ECCN) of your product under the EAR. After scouring your website the only information I have been able to find is from 2013 and references ECCN 5D002.c.1 and licence exception 740-13 (e) TSU Unrestricted. This information is however out of date and paragraph (e) of the TSU exemption no longer exists.
> Could you please confirm what the latest classification of your product should be? Many thanks 

I do find documentation in the US BIS site e.g.
https://www.bis.doc.gov/index.php/policy-guidance/encryption
but I also note some internal links on that site are themselves broken.

 
I will leave it to those that understand such matters to decide what documentation we need and to update documentation if necessary.
