1507679 - Firefox Nightly considered an unsupported browser by GitHub

Status: RESOLVED INVALID

(Web Compatibility :: Site Reports, defect)

Description

[blurryisconcerned]

Attachment: GitHub telling me I can't perform certain actions as Firefox Nightly is unsupported

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36

Steps to reproduce:

I only needed to go anywhere on the GitHub website to have the unsupported message show up.


Actual results:

GitHub telling me my current build of Firefox Nightly is unsupported (error message pops up every once in a while). This issue has been happening for a few weeks now, sometime around the Firefox Nightly 65 branch.


Expected results:

GitHub shouldn't recognize the Nightly browser as unsupported.

Thanks for the report blurryisconcerned. I'm unable to reproduce the issue in Firefox Nightly 65 for MacOS.

Are you using any extensions that could be changing your user agent string?

Ah yes, it turns out something was changing my user-agent without my knowledge. GitHub now considers my browser as supported, apologies.
