It's overly simplistic in its categorizations and therefore breaks things more often than not.

Breaks all google sites - including agenda.
No option at all (white liste for example).
Not managable at all.
So, can't use it !

I just installed this and immediately a web page appears demanding money for this product. Really, guilt me into paying monthly, annual donations for an extension that I'll likely uninstall later today because most extensions are useless garbage. And then you call this an honor system. LOL@you!

Beware. This is not open source. It is written at the bottom of their own page: https://github.com/disconnectme/disconnect

Did not make pages load any faster than before. Also, breaks all google sites - content in drive, youtube, etc does not show up and when I got to a google doc by having a link directly sent, I could not type anything.

Why do you not have options - this new update caches pages - and I don't want that - sure, some might - hence the need for choices.
so - uninstalled.

Deceptive licensing, dead project (no updates in over a year), and does not play nicely with other privacy enhancing add-ons.

The Addon is dead, no Updates since 2 years, better use Ublock Origin and Privacy Badger

After a while the Disconnect icon turns to a jigsaw icon. That does Firefox incapable to connect any site. I don't know what happens but it's grazy!

Used it for 2 years, but now it started collecting data and sending it back to their server. Something has changed and it's different to before. Basically, now it's spyware. So, beware, monitor outgoing traffic from your PC.

Pas d'icône, bien que l'extension ait été installée avant ADBlock.

This is bad

The "content" option should be blocked by default!
If an user found that it breaks websites, then he might have the option to unblock "content".
It is a shame to force all users to behave as soft-users. You are downgrading users to the same low level.

Also, if you don't block "content" by default, then why do you count "content" as blocked?
It should not appear at the counter in the icon.
It is a shame (if not a scum) to do that.

And worst, if an user blocks "content", why the add-on doesn't remember/respect user' choice after browser restarting?
Why users must block same "content" at every session?
... just crazy!... so mediocre!

And you are hearing from us users, the same complains every year... and nothing, zero changes, zero improvements.
You deserve zero stars due to your blindness along so many years.

The license for this add-on is falsely stated here as GNU GPL 3.0. This add-on in fact also includes two proprietary (non-free, not open source) third-party software products, as stated on the add-on's github page (https://github.com/disconnectme/disconnect). Claiming that the add-on is free software and licensed exclusively under GNU GPL 3.0 is highly deceptive, dishonest and inaccurate. Please rectify this and include the licenses of all software parts of the add-on on its official Mozilla Firefox add-ons page.

I've now reported this issue to the authors, to amo-admins@mozilla.org, via the form on its AMO page and on Mozilla's forum (https://discourse.mozilla.org/t/information-about-add-on-stated-incorrectly-by-authors-on-amo/23377). All with no effect, the mistake remains. Apparently any add-on developer can just claim anything they want about their add-on, there is no control. It's good to be aware that addons.mozilla.org can't be trusted and doesn't really care to provide accurate information about add-ons.

useless with uBlock Origin

With Firefox Version 57 (the new Quantum), I no longer have an icon on my toolbar which allows me to control it (e.g., whitelist). I removed Disconnect, NoScript, and AdBlockPlus, restarted Firefox, and then installed Disconnect again. It does show to be installed; but no joy! No icon.

This program was installed without my permission. I'm generally pretty careful about looking for all of the click boxes and check the terms before installing a program - though I do give the terms a quick scan. Generally, anything that sneaks its way onto your computer should be treated with great suspicion.

Same problem as the user levdr. I now have a green jigsaw icon instead of the black D. Pressing it does nothing. Using firefox v57.0. Been an incredible extension until now.

I've given up using this extension. I don't have the proper icon, stats or anything anymore. All started since the change from legacy.
