The issues in the new version of add ons is caused by cookies permissions.
If you use a cookie controller (for example cookie monster) put allow cookies as default action.
If you do that the new version works perfectly

Thanks for this add-on. Still giving some sort of problems, but it works what it's made for..

It stoped working months ago. Even after several Firefox updates it still does not work. Tried on Win 7 an Win 10. Several install/uninstall plug in attempts, several reboots, so I guess the thing just does not work. For what I read, it is pretty common, not just "scattered" cases.
Just a green jigsaw piece that does not do anything.

I use Firefox 52.1.1 ESR and the behaviour is the same as previous versions of FF. It has varied from NO icon, to an icon that looks like a puzzle piece. Either way, there's no way to do options at all. Not worth using if there's no options or display that contributes. This has been going on for quite a while now with nothing done to help this. Why?

The latest version works fine with Creator and FF53 -- except when I forget to untick "clear cookies" when clearing my history during a session. Then it's time to re-boot Firefox. I have tried several alternatives to WOT, and Disconnect is the best I have found so far. It plays well with uBlockOrigin. A very nice add-on, thanks for the work!

Oh, and don't' forget to run an un-Sandboxied sessions if you want your settings to stick....

I've had considerable problems getting Disconnect to "stick." During a session, the green "dashboard" would be replaced wiht a minimal list that was not responsive. I could re-activate with a "disable/enable" sequence in the add-on manager, but that was really clumsy as well as being subject to random failure again. After some research, I discovered that, when clearing history (which I do a lot; nervous twitch, I guess), THAT was enough to cripple Discovery. Still further trial/error indicates that unticking the "cookies" box fixed my problem. So: short answer: don't mess with the cookies. Who knew? This is a good add-on, and worth the trouble. Thanks!

Older version 3.15.3.1 is stable with Firefox 53.0 and icon displays "D" functionality correctly. Icon reverts to generic green blob and functionality disappears with most current 5.18.21 update (Firefox 53.0, WIndows 7).

Doesn't work on the Facebook website itself. Too bad.

Used to work efficiently for years , but after the last addon update , every site preferences resets to default after close the browser . I am tired to set each websites preferences every time i open Firefox , again and again.Please make this addon , to save each websites preferences , as it was happening before last update, otherwise i am sorry , but i will stop use it anymore.

Aide à protéger la vie privée, merci !

Used to work (until a few days ago), tried re-installing, still doesn't block ads. Time to go look for another product.

03-APR installed update and everything seems to be working fine now

It was working very well until the latest update. Now, it annoyingly sits on the toolbar with a long 'View and manage requests' label; the site preferences have to be reset every time I start the firefox and the site speeds are low, defeating the original intent of this add-on. Please roll back whatever update you did recently.

従前より、このアドオン（アプリ）に対しての評価は、バラツキが見られ、不思議でなりません。
UI （ユーザーインターフェイス）が、非常に単純化されているので、理解しづらいのかもしれません。
ホームページ＞ https://disconnect.me/
FAQ（Frequently Asked Questions ：よくある質問）＞ https://disconnect.me/disconnect/help
を参照すれば、疑問点は雲散霧消すると思われますが・・・。
アプリも解説も全てが、US米語のみで、多言語化がされていないので、
S3.Google Translator （https://addons.vaultpit.io/ja/firefox/addon/s3google-translator/?src=cb-dl-mostpopular）などの翻訳アプリが必要かもしれませんが。

このアドオンは、３年半ほど前から使用しています。
期待されるべき機能が申し分なく、大変、満足しています。
あまりにも素晴らしいので、昨年、有償版アプリの「プレミアム」に 、UpGrade しました。

プレミアム版の VPN は、TorBrowser と遜色のない Secure な機能を（Window-PC、MAC/iPad、Android の）3 devices に、もたらしてくれます。
Tracking を阻止し、Traffic の安全管理と秘匿化（masking）を実現できます。
絶大な信頼を寄せており、このアプリ無しでは、安心感を得られないほどに満足しています。


【追記：March 30, 2017】
デスクトップアプリの「Disconnect-Premium」に UpGrade しており、 Browser も Pale Moon 27+ を常用しています。
休眠中だったサブブラウザの Firefox を最新版（52.0.2）に更新したところ・・・、Disconnect の Browser-Extension（アドオン版）に、（最近、 Reviewer が相次いで指摘している）不具合を確認しました。
開発側の回答は 『Mozillaが、update の承認適用を完了していないため』 とのことらしいが、その最新版（Disconnect 5.18.19）に於いても「UI」が、意図せぬ表示になり、機能不全です。
a screenshot of the "View and manage requests" label を「サポートメール」し、対応を要請しましたが・・・、
いち早く、互換適合がされ、再び、素晴らしいパフォーマンスが発揮されることを願います。
評価（★★★★★）は、正常動作時でのものです。
＞最新版：Disconnect 5.18.21（最終更新日: April 2, 2017）が、リリースされました。更新直後は、正常に動作をしました。しかし、翌日、PC を再起動し、Firefox 52.0.2 を立ち上げると・・・、またもや「機能不全」状態が再現されています。しかもブラウザの挙動も不安定。当面は、「無効化」を選択します。

因みに、デスクトップアプリの「Disconnect-Premium」は、Browser には影響されないので、問題はありません。
年間$50ですが、日額$0.137（≒14円）です。費用対効果（満足度）は抜群です。「Premium」版への UpGrade をお薦めします。
＞ Tor-network 同様に、国際間の VPN を経由させるので、時差が掛かり、接続確立も “数秒から数分も要する” ことがあります。Location-Control は、USA／Asia／Europe（仏）／Germany（独）の 4箇所から任意選択できます。

Since new version 5.18.17 every time I start Firefox an annoying Disconnect web page pop up appears. Please turn off that.
