1286198 - Firefox user agent truncated when a service worker is registered

Status: RESOLVED DUPLICATE of bug 1286125

(Core :: General, defect)

Description

Details:

The statistics page above displays on overlay element, stating:

 To try the thousands of add-ons available here, download Mozilla Firefox, a fast, free way to surf the Web! 

But I am browsing the page from Firefox:

navigator.buildID
    20160711143754
navigator.language
    en-US
navigator.languages
    en-US,de
navigator.userAgent
    Mozilla/5.0 (X11; Linux x86_64; rv:50.0) Gecko/20100101 /

I would suggest this information should only be displayed in browsers other than Firefox.

This is not a security bug. Please file non-security bugs at http://github.com/mozilla/addons/issues/new .

Thank you.

This is a Firefox Nightly Bug. My user agent is:

"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:50.0) Gecko/20100101 /"

and?

"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:47.0) Gecko/20100101 Firefox/47.0"

Note the "Firefox/..." on the end. 

Its that which AMO uses to determine if you are using Firefox or not.

I think this could be related to Bug 1286126

That's not related to the UA at all, though...

Andy, where does this UA come from? Are we sure this is about the UA rather than the bug Alex referenced?

Either way, this is a gecko or an AMO issue, so moving to core for now.

That came from Nightly I downloaded this morning.

I'm 100% sure if you send the proper Firefox user agent to AMO, it will detect as Firefox.

My user agent in today's Nightly says:

"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:50.0) Gecko/20100101 Firefox/50.0"

But if I have a service worker registered I get upon restart:

"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:50.0) Gecko/20100101 /"

Great, so this is just a dupe of bug 1286125 which will likely also be fixed by bug 1286126.
