Hey. After the creation of the issue in my repo (in this case), all attempts to gain access to the this repo "..../src" url result in a bug in the console:

Uncaught TypeError: Cannot read property 'isInlineDialog' of undefined links.js:40:
"if (!addon.options.isInlineDialog) {"

At the same time, when cleaning the cookie, the login page is opened, but after the authorization, the error still does not allow using the "/src" url. Also, if you go from an incognito or another browser - everything is OK.

Previously I encountered exactly the same error, but how it emerged and how it resolved itself - I do not remember (probably by reloading the browser)

Browser: Google Chrome Version 69.0.3497.100 (Official Build) (64-bit)
OS: macOS High Sierra Version 10.13.3 (17D47)

p.s. sorry for my english =)
