I understand why the developer re-wrote the extension to work with Firefox's future requirements... BUT the implementation of going from 3.5 to 4.0 was NOT smooth. Give users a warning or the option to back up our saved settings and import into the new version. Like another user said, I can only click on one e-mail at a time to launch. Used to be able to one click and open all e-mail accounts with messages. This app needs a lot of fine tuning to get it back up to par with the old version.

no session for each tab, need relogin to switch different account.

latest update is a bummer!!!

The new update is very bad. It wiped out all my settings and cannot open multiple accounts from the same email provider after re-configuring email accounts.

been using for almost year, never will come back to this after the latest update which erased all accounts, no toolbar.

The extension stopped working after last update. All configuration is gone. After restoring to last configuration from backup, not verifying any account and multi accounts not working. I had to install previous version.

After last update, this add not be the same! Is worst is possible!

Latest update wiped this out for me. All login info is erased, button grayed out. Unusable... damn shame it was the BEST!! ;( :( ;(

Why was this made?
This add-on was so nice and clean and easy.
With the update everything was erased I had to do it over again, scripts-support removed, multiple account do not work.
Just awful. Uninstalled it.

Went from clean, simple, easy to use, to clunky and cumbersome. Congrats

After the version 4 update it wiped out the previous settings and had to re-set them up.

This stopped working after update. Now i have got to go search for an older version and turn off auto-update. Ugh.... :/

Edit: I suggest, that for now, everyone look at the version history for this addon, and select an older one, when you hover your mouse over an older version a +Add To Firefox button appears. Just did that and everything is fine now, hopefully this gets fixed.

Be sure to turn auto-updates off as well...at least for now.

La versión 4.0.2 no funciona, no aparece el menú de acceso a mis cuentas de correo electrónico registradas, he vuelto a la versión 3.5.23 y todo correcto.

La version 4.0.2 ne fonctionne pas, il n'y a plus le menu avec l'accès aux comptes mails enregistré, retour à la version 3.5.23

3.5.23 works fine but neither of the 4.x versions work with firefox 50. Yahoo works 1 time then it just gets stuck on checking. Also, after rebooting firefox all of the settings and email accounts are blank!

Desde que Firefox actualizó su navegador a la última versión v49.0.2 e incluso en las betas v50.x, todo el trabajo anteriormente realizado por el desarrollador del complemento se ha ido a la basura, ya que ha dejado de funcionar y pierde constantemente la configuración almacenada de las cuentas. En fin, ¡¡¡UN DESASTRE TOTAL!!!

Does not work with Firefox 50 beta

and Firefox Nightly 52.01A - not work

I noticed that latest version does not store account information. Once you restarted firefox all your account and configuration is lost.
