Can’t Log into Feedly or Pinterest on Firefox 40? Check Ghostery!

NOTE: This article is out of date and likely obsolete.

I use Feedly to keep up with a lot of sites ranging from tech to entertainment. After upgrading to Firefox 40, I wasn’t able to log in using my Google account. The authentication pop-up would only bring up a plain HTML page saying, “Moved Temporarily The document has moved here.” The same problem occurs with Pinterest and Facebook login, though in that case the authentication pop-up is blank. Pocket also shows the “Moved Temporarily” message, but recovers. I’m having trouble logging into Disqus too. Lots (but not all) of third-party logins seem to be broken now.

Update: Ghostery 5.4.8 fixes it

TL;DR: Use this workaround!

  1. Go into Add-Ons and disable Ghostery.
  2. Log into Feedly / Pinterest / whatever.
  3. Go back into Add-Ons and re-enable Ghostery.

Troubleshooting Process

A discussion on Google+ suggested disabling add-ons. I tried it, and was able to log in – great! But I wanted to know which extension was the problem.

After experimenting a bit, I found that disabling Ghostery allowed me to log into Feedly with Google.

Just to make certain, I logged out of Feedly, re-enabled Ghostery, and tried logging back in. Sure enough, I was back to the “Moved Temporarily…” error again. I’ve had Ghostery on this browser for a long time with no problems, and the about page shows that the extension was last updated toward the end of July, so I assume the problem is that something in Firefox 40 changed the way the browser, Ghostery and OAuth interact. I wouldn’t be surprised if it runs into issues with other privacy add-ons like AdBlock or Privacy Badger.

Fortunately, Ghostery can be turned on and off without restarting your browser. And turning it back on after you’re logged in doesn’t seem to interfere with Feedly.

I may go back and try to figure out the specific setting that’s causing the issue, but for now, I’m able to run both Feedly and Ghostery, so I’m not in too much of a hurry.

Updates

Update: Ghostery will be releasing a fix to resolve the bug, which turns out to affect quite a few sites. (via Feedly on Google+.)

Update: Ghostery 5.4.6.1 is supposed to fix the problem, but it still breaks login on some sites, including Feedly and Pinterest.

Update: Ghostery 5.4.8 fixes it
