STARTTLS support || [Proton Bridge]

ibu600

Just an update here. There is a alpha version of Proton Bridge -3.09
It allows to export the certificate which can be imported into Vivaldi.
The default import location is WRONG. You must select Trusted Root Certificates.
After importing the certificate, Vivaldi needs to be restarted. I guess it caches the certificates for speed.

This worked incredibly well and much simpler than some of the other workarounds. I needed to restart the computer (since restarting vivaldi wasn't enough). Thank you

Still not working :((
@ibu600 did you use STARTTLS?

@MoiraPrime said in STARTTLS support:

@PoorPocketsMcNewHold I figured out how to get it to work. What I ended up doing was taking the key and certificate and converting them into a pfx using openssl, then importing it as a personal certificate in the certificate store of Vivaldi. Then I was magically able to get it to work.

Could you please describe how you concverted the .pem's into .pfx using openssl?

For anyone struggling setting up Proton Mail, I was able to get it working thanks to the answers in here from @777pirat , @PoorPocketsMcNewHold. However, there was a few additional steps needed prior to setting up the account in order to get it working; mainly regarding where to add it and which authorities to give. If done correctly, there is no need to convert the certificate into a different file format (as has been suggested).

For anyone interested, I've summarised the actions I had to undertake prior to setting up the account in a few relatively simple steps:

In Proton Mail Bridge (v 3.1.1) go to "Settings">"Advanced Settings".
- Go to "Connection Mode" and click "Change". Change IMAP connection mode to "SSL".
- Go to "Export TLS certificates" and click "Export" and save the files at your location of choice.
In Vivaldi, open a new tab and enter vivaldi://settings/certificates. The "Manage Certificates" page should then open.
- Under the "Authorities" tab click "Import" and select the cert.pem file you exported from Proton Mail Bridge.
- A prompt for "Certificate authority" should then pop up. Tick off all boxes under "Trust settings".
Restart Vivaldi and Proton Mail Bridge.

After that, it should be possible to set up a Proton Mail account.

@palbjartan Nice. Just a note: step #2 might be not valid for windows.
But I think the same cert can be add to Window Certificate Manager.

Thanks for the info. I got the instructions for adding certificates from the Vivaldi for Linux forum, as @BernieV 's way of adding certificates is unviable (at least on Linux). I'm somewhat surprised it wouldn't work for Windows users as well, since it's a Vivaldi internal setting and not system wide, but since I don't have Windows I am unable to test it.

Can anyone confirm whether step 2 will work in Windows or not?

Step 2 does not work on Windows but importing the cert.pem in Windows Certificate Manager works.

In Windows Start menu, search and open Certificate Manager
Expand Trusted Root Certification Authorities > Certificates
Right-click on Certificates folder & select All tasks > Import
Import cert.pem

Same problem here. My university's IMAP server connects on 143 with StartTLS. Cannot set that up in Vivaldi. It's greyed out. Unfortunately there is no alternative like SSL. Will resort to Apple Mail for now but would love to have it in Vivaldi.

6.0.2979.18 (Stable channel) (arm64)

@rjc3rd Maybe Vivaldi don't have 10,000 programmers working around the clock to attend to every wish and winge. Let's all lighten up a bit here. Don't like Vivaldi email at present? There are 20 other email clients (FREE) you can choose from.

Just sayin'. $:\$

I would like to report that I was able to get Proton Mail running without issue and without much work on Linux. The solution required splicing together different solutions made throughout this thread.

These are the steps I took to get Proton Mail working for me.

Browser OS: Vivaldi 6.1.3035.204 (Stable channel) stable (64-bit)
Distro: Debian 12 (Gnome)

From palbjartan

In Proton Mail Bridge (v 3.1.1) go to "Settings">"Advanced Settings".

Go to "Connection Mode" and click "Change". Change IMAP connection mode to "SSL".

Go to "Export TLS certificates" and click "Export" and save the files at your location of choice.

If the above does not work try this:

In Thunderbird, go to:

Settings > Privacy & Security > Certificates > Manage Certificates
- Click on Authorities, Scroll down to: Proton AG
  - Certificate Name = 127.0.0.1
  - Security Device = Software Security Device
- "View" certificate. Scroll down to "Miscellaneous"
  - Export certificate by clicking on PEM(cert):
    Download PEM(cert) PEM(chain)

In Vivaldi, open a new tab and enter: chrome://settings/certificates
- The "Manage Certificates" page should open.
  - NOTE: chrome://settings/certificates forwards to vivaldi://settings/certificates.
  - BUT: vivaldi://settings/certificates brings up "Settings" without access to certificate management.
- Under the "Authorities" tab click "Import"
  - Select exported certificate: 127-0-0-1.pem (Thunderbird)
- A prompt for "Certificate authority" should pop up.
  - Tick all boxes under "Trust settings".
Restart Vivaldi and Proton Mail Bridge.

@Truongdukedong I understand the sentiment but when you build a product or service and parts of it fail to work as intended the correct response should be to fix whatever is broken and not suggest unofficial alternatives whenever possible.

Vivaldi doesn't have 10,000 programmers but the nature of open-source development lends itself to people with programming skills or technical knowledge filling the role of those programmers and providing solutions, similar to the message I made on this topic.

If people are upset that a product doesn't work right, then that product is (probably) a good one and people have high expectations for how it should work.

It is highly unlikely that Microsoft ever told people to go use Google products because of a flaw in a Microsoft product. Don't you agree?

Vivaldi Mail and Proton Bridge

[Note] Since Vivaldi does not support STARTTLS for IMAP (due to security issues with STARTTLS), you need to set Proton Bridge to SSL mode

Go to Proton Bridge advanced settings and set both connections to SSL and export the cert.pem somewhere.
Open chrome://settings/certificates and import the cert.pem into the Authorities tab. Accept all checkboxes.
Restart Vivaldi and Proton Bridge.
Re-enter the username and password from Proton Bridge and it should work.

Hi tr3k,
I've generated the certificates but when I go to vivaldi://settings/cerfificates there is no Authorities tab.
There is Security and Privacy > Security > Manage Certificates.
Or if I go to chrome://settings/certificates I end up at vivaldi://settings
I'm none the wiser as to where the cert.pem gets installed.....
Any advice? I'm using MACOS 13.4.1 on an M1 Macbook Air.

craigcpcb

Has anyone actually managed to get Proton Mail working in Vivaldi on an M1/M2 Mac?
I've looked at all the answers so far and when I get to vivaldi://settings/privacy/ > Security > Manage Certificates, I end up in Keychain Access.
I have no idea what to do next....
Anyone??

michaelbehan

@qutib Thank you. This worked for me. I did get an error message from PM Bridge that my the client used an invalid password, but within 2 minutes I received all my PM emails. Thanks again.

albertoru

Dear all,
I add myself to the list of those who would like the StartTLS option in the input email server. There are news on this topic?

stardepp

@albertoru This desired function is already on the Vivaldi team's to-do list, but a release date has not yet been set. See also screenshot:

It's working for me as well, thank you very much for your help.

When in the menu for adding an account to Vivaldi mail there is now the logo of Protonmail besides Google, Outlook, Fastmail etc. Has it always been there or has it been recently added?
