PLEASE DOWNGRADE FIREFOX TO 39.0.3 TO USE THIS WONDERFUL FEATURE. PLEASE VOTE ON https://webextensions.uservoice.com/forums/315663-webextension-api-ideas/suggestions/9437394-add-an-api-to-monitor-and-alter-existing-about-con
Apparently, updated Firefox (currently 40.0.3) disallow something that this add-on needs. So it's up to Mozilla now to update their policy.
I've downgraded Firefox to allow "toggle cookie" to work because i think this is more important that any security update!
Firefox 39.0.3 for Windows : http://filehippo.com/download_firefox/62612/
Firefox 39.0.3 for Mac : http://filehippo.com/mac/download_firefox_mac/tech/62620/

I don't like the idea of being tracked without my knowledge or permission so use Toggle Cookies to turn off cookies when not needed. It is by far one of the best add-ons someone could have. That being said, all of a sudden it has disappeared from the menu bar. I have removed it and reinstalled it, but it still doesn't show up. I suspect Firefox has struck again and messed with add-ons by way of an update. Very irritating, to say the least. I hope this problem will be fixed soon.
I've been happily using this add-on for years but it's suddenly stopped working. It was fine yesterday but now the icon has disappeared and there’s no sign of it anywhere when I press the Firefox ‘customise’ button. Very useful tool though, assuming this problem can be fixed.
I really like this add-on. It's simple and easy to use. Thanks for your work :]
Update: with version 0.7.4 everything works fine again, thanks for such quick response :]
There is a bug on Firefox 22 and Toggle Cookies 0.7.3 that makes button icon invisible in Private Browsing Mode. On the previous version 0.6.0 you can see button but it doesn't work, now it's completely gone.Thanks again for great add-on.
I initially didn't think it mattered in private browsing what the prefs were because it never saves cookies, but then decided if the users want it, they get it! You can get 0.7.4 now while it awaits review from the "View all versions" link at https://addons.mozilla.org/en-US/firefox/addon/toggle-cookies/versions/
I've never had it in the add-on bar, as I also don't have that bar visible. See https://bugzilla.mozilla.org/show_bug.cgi?id=586029 for why I have no say in where the icon is put, otherwise I wouldn't put it there. I moved it to the Titlebar for myself, as you can see in the screenshot I uploaded for it, and it stays there for me across restarts.
The moveability of the icon is totally dependent on the underlying add-on kit which this add-on uses, so please file a bug with the maintainers of it at https://bugzilla.mozilla.org/enter_bug.cgi?product=Add-on%20SDK
There is hope in https://bugzilla.mozilla.org/show_bug.cgi?id=695913 for having icons in the navigation bar, and if by process of elimination you discover another extension triggers this bug, we can inform that extension's author. I'm sorry about the formatting of this reply, the form doesn't allow clickable links, and thanks for the review, I appreciate it :)
