Now drag-drop file to this window and appears the option to install the new extension.

Contacts Sidebar enfin ! Rated 5 out of 5 stars

Un grand merci à Stéphane qui a donné une solution (ci-dessous le 1 septembre). J'étais resté sur la version de Thunderbird 51 pour continuer à utiliser Contacts Sidebar. J'ai ENFIN pu passer à la dernière version 56

Thunderbird 52 - contactssidebar Rated 4 out of 5 stars

Stephane I just read I could download I've done it.
But how should I install it? It's not an add-on for Thunderbird. I've still got:
XML-parse error: undefined entity
Location: chrome://contactssidebar content/contactsPanel
xul nr 250 col. 9
<label value="&searchInput.label;">
Please note I'm not a Win user, I'm an Ubuntu Linux user. But I don't there's much difference. Pls advise how to install everything in the zip-file.

Sidebar's Demise Rated 5 out of 5 stars

Love the add-on, have been using it for years. And I'm very sorry it's not being taken care of. Can maybe some coder buy it from the owner. Love live my hopes for an updated version.

Reason we need a contacts sidebar Rated 5 out of 5 stars

In reply to gmeades's post, the reason we need a contacts sidebar is that it is stupid to have to create a dummy email simply in order to be able to look up someone's telephone number, or postal address, or to see the notes in their contact record. The logical place for a contact sidebar that contains all of the above information is to the left of the inbox, not within an email, and that's why the Contacts sidebar transformed Thunderbird from a decent but flawed email client into an excellent one. Why Thunderbird's developers haven't made this functionality available in the core product is beyond my understanding. I hope the developer of the add-on makes it work with TB 52 soon, as I am greatly missing having it's functionality.

One of the best addons for thunderbird! Rated 5 out of 5 stars

That addon is the most usefull addon for thunderbird! I don't understand why the mozilla-developers did not build it in thunderbird! Please bring it back for the new releases! Or stop the "every-week-a-new-version"-strategie. It is really annoying to lose perfect addons at every update on thunderbird!

Thunderbird Already Has Contact Sidebar Built In...! Rated 1 out of 5 stars

I have no idea why anyone would want to go through the time and trouble to create this, as Thunderbird has always had a Contacts Sidebar built into it.

In any new email window, just press the F9 key and the address book sidebar appears... This has been a feature of Thunderbird like.... forever....

Press "Write" to bring up a new email window, press F9, and the Contacts sidebar appears. You can right click on an item in the sidebar and a context menu will come up showing you different options that are available, like "create a new address book" or "add contact", etc.

Thank you Sparky! Rated 5 out of 5 stars

This is not to rate the original developer's work (he seems long gone :-( ) but Sparky's effort to bring this invaluable add-on forward to newer versions of TB!
The revised add-on works flawlessly under 38.3. That is one fine job you did here! One can find the download here:

Hard to believe this is the ONLY extension that does this sidebar Rated 1 out of 5 stars

I'm new to Thunderbird (days old) and why are all the extensions here SO OLD? I'm concerned about security. Maybe Thunderbird is an obsolete client?
