Why is my browser spawning invisible windows?

Operating system: OS X 10.9

Starting about four months ago, I began to see untitled and non-selectable windows spawning after my browser had been open for a while (i.e. after I visited a few sites). The number of these invisible windows grows over time, but are removed if I close the browser and start a new session. This has persisted through many new versions of Firefox.

I tried turning off all of the add-ons. Still happened.

I tried keeping track of what sites caused the problem. No correlation.

Today I uninstalled Firefox, using AppZapper -- which should have removed everything -- then did a new install. The only thing that I imported were bookmarks from the backup directory in my old Profile folder.

...and it's happening again. Here is a screen shot: http://imgur.com/ojcODd1

Any help would be appreciated.

Isisombululo esikhethiwe

By default "privacy.clearOnShutdown.cookies": false, is usually true. and network.cookie.lifetimePolicy": 1, is usually 0.

I do not know exactly if this is the result of cookies not being removed, however these are the about:config entries that stand out from version 34.

I did have Adblock Plus installed. Currently I am running Adblock Edge.

Have you tried the mal-ware scan?

Yes. ClamXav found heuristic matches in gmail archives, but nothing that seemed like an active threat.

I believe that I have found a clue:

If I leave only a single tab open, I do not get the invisible windows. It's only when there are multiple tabs. This leads me to believe that opening a new tab creates this window instance.

Now I'm just not sure what to do with that information...

Having more than one version of a program may cause issues.

That's really interesting. App Zapper was supposed to remove everything related to my previous installation, but it appears that all of my plug-ins are there. I'm going to manually delete those and see if that helps.

Thanks! I'll report back.

I removed the earlier instance of BlueJeans plug-in and everything seemed to be going well, but today the invisible windows are back :-(

I've called the big guys to help you. Good luck.

Does your sessionstore file have a large number of blank entries? (textedit or notepad) Profiles - Where Firefox stores your bookmarks, passwords and other user data

Looks like this is a test version of Blue Jeans? https://community.bluejeans.com/bluej.../firefox-equivilant-of-google-chrome-extension

The file called sessionCheckpoints.json has this in it:

{"profile-after-change":true,"final-ui-startup":true,"sessionstore-windows-restored":true}

and, interestingly enough, I do not see a file called "sessionstore.js" in my profile folder. Other .js files are not hidden. Could that be the issue?

You are right that there is a more recent version of the bluejeans plugin. I have installed it, and hopefully there won't be two versions this time (though now I know how to manually remove the old one).

more options

That is because they moved to session-backups folder. There are the last 5 or 6 sessions.

Mine says the same, sorry wrong path: {"profile-after-change":true,"final-ui-startup":true,"sessionstore-windows-restored":true}

Ok, what else can we try as I type aloud. Try to rename recovery.js to recoveryold.js and rename the recovery.bk to recovery.js and restart Firefox.

more options

No luck. I'm going to try removing everything - the app, the extensions, the add-ons - whole shebang - then reinstall.

If that doesn't work, do you have an exorcist on duty?

-( I deleted all of my add-ons. Removed any folder in both the all users and my username's Libraries that was related to Mozilla or Firefox. I used AppZapper to remove the application and its associated files.

The only thing that I put back in was 1Password.

STILL getting spawned windows.

I will change those entries and see if it makes a difference.

Definitely an issue on shutdown as well. I will ask someone to take a look at this too/

more options

I have been running the browser all morning and thus far no invisible windows :-)

It did delete all of my cookies after I shut down the browser, which meant any two-factor sites that I signed into previously were once again suspicious of me. I will undo that bit of privacy control and see if the problem returns.

more options

Still no spawning invisi-windows for a couple of days. I'm re-adding add-ons one by one (but only the most critical - some of those were leftovers that should have been deleted a long time ago).

I am adding Adblock and will see how that goes.

Thanks!!!!

Problem seems solved. Thank you muchly for sticking with this one until the end.
