Minimized startup after entering the password possible? Rated 5 out of 5 stars

It would be nice if there was a function in startup master to start thunderbird minimized. I have quite a lot of accounts in thunderbird and it takes some time after entering the passwort until everything is loaded and ready. In the meantime i do something else, and its quite annoying when the thunderbird window pops finally up and then interrupts e.g. typing in another window.

Good extension! But is webextension version possible? Rated 5 out of 5 stars

As you know the 57 version of Firefox is coming quick. Thus just want to ask are you going to port it to webextension or at least if it is possible? Thanks.

I intend to port it, but unfortunately the new webextension API doesn't provide the necessary functions yet. Chances are that the add-on will be broken for a while after the release of Firefox 57 until the API is implemented in Firefox.

You can follow the progress of the master password API:

Works good Rated 5 out of 5 stars

... on windows. But clicking “cancel” will still produce plenty of prompts for master password. Better to chose “Quite” if “cancel”. To keep it clean.
Would be nice with a “pin code” function, i.e. a few characters that is only valid for a few attempts and then have to use the “real” long password.

When you click on the cancel button,the FF will still be open??!

When you installed the add-on, you were asked if you want to quit if the dialog is cancelled. You can still change it in the extension settings.

Saves my day on each day! Rated 5 out of 5 stars

I'm using version 1.6.2 with TB 52.1.1. 64-Bit on Ubuntu Mate 16.04 and NEVER had any problems with it so far. Using email and shared web calendar accounts along with my IMAP and POP email made me have to supply my master password 3 times when TB started (by showing me independent 3 login prompts while TB's UI was already open - I didn't like that).
This is now streamlined to 1 login before TB's user interface even appears. That's exactly what I need it for and it does a perfect job here so far. Thanks for this addon!!

[FIXED] Currently not working on ThunderBird 52.1.1 Rated 5 out of 5 stars

Currently not working on ThunderBird 52.1.1 but I'm confident it will soon!

You should really open up some account for donations, or, get directly in touch with the dev team to correct this once for all, this is really an embarassing issue!

Kind Regards,
Alessandro Salvati

EDIT: Thank you for your answer! I still don't know why Thunderbird hasn't upgraded yet but your answer definitely fixed my issue :)


You can either use StartupMaster 1.6.2 with Thunderbird 52 or StartupMaster 1.6.3 with Thunderbird 53+. I've marked 1.6.3 as incompatible with Thunderbird 52, I'm not sure why Thunderbird allowed the upgrade in the first place. (You can downgrade to previous versions by following the "Show compete version history" link in the "Version information" accordion.)

great tool, but doesn't work with TB 52.1.0

Not Working in FF53 Rated 3 out of 5 stars

After updating to FF53, FF53 will not start. I'm lucky to have some computer knowledge so I have started FF in safe mode and do some diagnostics, and found this add-on to be the problem. But for the average joe, the only thing they have is frustration and turn away from FF. I myself has switched to chrome for 1 day before i found out the cause, if I'm not a FF lover I'm afraid I will just left FF and use other browser instead. How FF can detect faulty add-on is something Mozilla needs to address.

This is actually a Firefox bug. StartupMaster 1.6.2 was explicitly marked incompatible with Firefox 53, but Firefox only disables (or upgrades) the addon after the first successful startup, which never happens. I've implemented a workaround, but you need to upgrade StartupMaster before you upgrade Firefox, otherwise there isn't much I can do to help you. I can't touch the old version already installed on your computer.

FF53 update needs attention Rated 5 out of 5 stars

I also wondered that FF does not start after upgrade to 53. Safe mode did, obviously silently updating this addon, so the next start worked.

BUT: It did not ask for the password on startup! Did a quick research and found there were no options for this addon (1.6.3). So I had to manually remove the update and do a clean install again. Now it works as before!

UPDATE: Now version 1.6.3 already installs on FF52. I verified with my existing profile by re-installing FF52. It first disabled StartupMaster 1.6.3 (the one for 53 only), updated to the AMO version 1.6.3 (for 52-53) and it worked. Then I did another update to FF53 and it still works.
Thanks htamas!!

Should be fixed now.

Thanks - Amazingly quick reaction! Rated 5 out of 5 stars

Instant panic time when my Firefox would not work after the upgrade to 53 (via Linux Mint 18.1). Going to safe mode and updating my add-ons did the trick, which is when I found it was this add-on and how quickly it had been fixed!
Obviously you care and are on the ball - I wish there were more like you in this world!

С 53-й лисой не работает (спасибо за обновление (2017.04.21), всё работает) Rated 5 out of 5 stars

Огромное спасибо за обновление, теперь всё работает с Firefox 53+

Дополнение отличное, но обновил лису до релизной 53-ей, и лиса не запускается, удалил {506d044e-41fa-4cc8-9dc6-9ff70e96eebf}.xpi из папки extensions , и лиса запустилась, во избежание подобных недоразумений, рукожопам-программистам лисы нужно лучше своё творение тестировать.
Но судя по отзывам "...StartupMaster causes Firefox 53.x (current Aurora) to crash....", об этой проблеме было известно ещё 31 января 2017-го...

Thank you - solves a great TBird PITA! Rated 5 out of 5 stars

Ihave about a dozen email accounts and the files are all on network storage which seems to make TBird take 1+ minutes to process. So when I start TBird I end up looking at something else and forget about watching for the prompt. SOmetimes 5-10 minutes have gone by before I notice it and then of course I have a dozen dialogs to find (amazing that they won't all show up in the same place) and fill in the password for... a real pita on an almost daily basis. This seems to solve that nicely and, so far, no side effects. The option to wait until add ons have finished could use a bit more explanation but that is a minor complaint. Thank you!

Complemento fundamental para Thunderbird Rated 5 out of 5 stars

Complemento fundamental para Thunderbird

He estado buscando una alternativa al complemento "Profile Password" y me he encontrado con "StartupMaster".

Sencillamente ... genial!!

Cumple su funcion correctamente. Es una pena que Mozilla no introduzca esta funcionalidad en sus opciones.

Es cierto que la seguridad del correo se puede saltar (no la de las contraseñas) pero esto ya no es un problema del complemento sino de la politica que sigue Mozilla. En cualquier caso, este complemento es fantastico para sentirte un poco mas seguro en tu pc de trabajo.

Y ademas, por lo que he visto, el desarrollador de este complemento esta muy atento a mejorarlo asi que muchisimas gracias!!!!

Repito, un complemento fundamental. Muchisimas gracias a su desarrollador.

Un saludo

Essential add-on for Thunderbird

I have been looking for an alternative to the "Profile Password" add-on and I have found "StartupMaster".

Just great!!

It fulfills its function correctly. It's a shame that Mozilla does not introduce this functionality into its options.

It is true that the security of the mail can be skipped (not the passwords) but this is no longer a problem of the complement but of the policy that Mozilla follows. In any case, this add-on is fantastic to feel a little more secure in your work pc.

And also, from what I've seen, the developer of this add-on is very attentive to improve it so many thanks!

I repeat, a fundamental complement. Thank you very much to your developer.

a greeting
