Doesn't work. Initial login/setup on desktop Firefox doesn't work. Error in browser console when trying submit email for login:

"Uncaught Error: error_permission" at onboarding-panel.js:9330:99

Doesn't work anymore, can't login.

Doesn't work anymore with there own domains, gmail.com and outlook.com works for this mail check extension but not their own like email.com, mail.com, gmx.com; what a fucking joke. I contacted the developer several times, he never responded even the support said to use another browser, contacted them through email twitter and they fucking never responded. I am a paying customer to their service, recently switched to firefox and this is how they treat us

If you check the necessary permissions, you will realize that there is a lot of telemetry and sharing of your browsing data.

Not working, simple as that.

Used to work, now it doesn't. Can't log in. Don't waste your time installing it.

What happened? Worked fine for ages, then login doesn't work. Just like the other reviewers, you can't log in when it is installed in Firefox. The company still "advertises" the extension as compatible. Yeah, no. I use their apps for Android and iOS which work fine. Fortunately, this is not my primary email. If it was, I would be very unhappy.

Used this a ton on other browsers and it worked just fine. Was an easy and convenient way to view emails from all of my accounts. I switched to Firefox and the extension no longer lets me sign in to any my accounts, freezing completely after I input my email and never prompting me for a password. Very disappointing.

too much spam in inbox, too much snooping and data accessing

Can no longer sign in to this extension for whatever reason. Pointless now.

Does not provide a means of entering password to log in when used in Firefox but works great in Brave.

I've used gmx.us for a few years now. I've even replaced gmail with it. Up until a week ago, I've had no problems, but now mail check is saying my browser is not compatible (Firefox which is up to date). What happened?

waardeloos. geen plaats voor wachtwoord als ik mail account wil toevoegen

Please FIX this app! It is not functioning anymore, unlike a few months ago when it worked smoothly after initial login. Now, the system hangs indefinitely right after installation and user login. WHY DID THIS HAPPEN???

If you are using Firefox this addon is useless. Even tech support said to use another browser. Makes me wonder about Mail.com.

Can't even log in.

Like many have mentioned, I also cannot add my account as when I try to do so, the login button becomes inactive and I never get prompted to enter a password.

Praticamente richiede l'accesso a qualsiasi cosa. Obbligano gli utenti a scaricarla per non dover inserire le credenziali ogni volta così riescono a tracciare qualsiasi cosa tu faccia

Was working fine. After installing Windows 11 22H2 and installing Firefox (v107) then adding the Mail.com extension, I cannot log in. The log in dialogue accepts my email address but never gets to the 'enter password' screen. Does the extension need an upgrade?

After installing, the login dialog doesn't work: there's a field to type in the email address and a "Login" button, which upon being clicked becomes disabled and nothing else happens.

Furthermore, it requires permission to "Access your data for www.google.com", and for "login.live.com", which I highly doubt are actually necessary for the extension to work and feel like privacy intrusion.

Dodatek wymaga zbyt wielu uprawnień,niewymienione wszystkie witryny,które maja dostęp do stron przeglądarki.

it has problem for logging into my accounts

There is only a place to enter my email address and no place to enter a password so my credentials always fail

Too intrusive. Requires access to way too much info.
