Add Protocol Handler to Settings

nickbrake

@Calli04 The following works, after restarting Vivaldi the preferences file had moved it to in between countryid_at_install and data_reduction

"custom_handlers":{"enabled":true,"ignored_protocol_handlers":[],
"registered_protocol_handlers":[{"default":true,"protocol":"mailto",
"url":"https://mail.google.com/mail/?view=cm&fs=1&extsrc=mailto&url=%s"}]}

Like this:

"countryid_at_install":12345,"custom_handlers":{"enabled":true,"ignored_protocol_handlers":[],"registered_protocol_handlers":[{"default":true,"protocol":"mailto","url":"https://mail.google.com/mail/?view=cm&fs=1&extsrc=mailto&url=%s"}]},"data_reduction"

Hi Nick, cheers, it worked as described after I firstly destroyed my preferences with a link to another mail service, but I was doing it on my testing device anyway.
It worked with Posteo:
https://posteo.de/webmail/?_task=mail&_action=compose&_to=%s
It did not work with mailbox.org, who seem to offer that functionality only for firefox. There the link hast this format, but this doesn't work in chrome either.

https://office.mailbox.org/appsuite/#app=io.ox/mail/compose/main:compose&mailto=%s

The main goal I could not reach, because in Ubuntu there is not connection from the default mail handler to the mail handler in the default browser, which I was hoping to set up by this.

@Calli04 What had me stuck for a bit was the data in %s which seems not to be the expected data for a standard "mailto="... Not sure where I found it, but it required "&extsrc=mailto&url=%s" instead of "mailto=%s". The %s actually has mailto=_____ in it. Maybe something similar is supported with Posteo or Mailbox.

@nickbrake Thank you! Your solution works! Just a heads up: when editing the Preferences file make sure Vivaldi is not running

Nice forum, I gain good knowledge in this forum. Thank you for all your comments and suggestions. I actually work on it this is very helpful to me. Good job keep posting

@nickbrake Thanks, this worked for me on Linux.

As others have said, shut down Vivaldi first, and ideally make a backup of the file before editing it.
If anyone else is looking for it, the file location was ~/.config/vivaldi/Default/Preferences

Does this work on a Mac? Where is the file that needs to be edited?

Thanks!

@burnout426 said in Add Protocol Handler to Settings:

You have to add the following JSON to the root object in Vivaldi's preferences file.

custom_handlers: {
   "enabled" : true,
   "ignored_protocol_handlers" : [],
   "registered_protocol_handlers" : [
      {
         "default" : true,
         "protocol" : "mailto",
         "url" : "https://mail.vivaldi.net/webmail/?_task=mail&_action=compose&_to=%s"
      }
   ]
}

How do I do this properly on current vivaldi-versions?
The file "C:\Users<me>\AppData\Local\Vivaldi\User Data\Default\Preferences" seems to be HEAVILY unformatted. Is that even the file you are talking about? Is there a way to do it "pretty" in Vivaldi??
I could run Notepad++ PrettyPrint over it, but I'm afraid to break stuff so that it breaks other stuff...

A small outtake to demonstrate its beauty:

{"account_tracker_service_last_update":"13311852163088663","alternate_error_pages":{"backup":false},"autocomplete":{"retention_policy_last_version":106},"autofill":{"credit_card_enabled":false,"orphan_rows_removed":true,"upload_encoding_seed":"39345C8332CACC8B685A4BA8B9C16546"},"browser":{"has_seen_welcome_page":true,"window_placement":{"bottom":992,"left":135,"maximized":true,"right":1577,"top":2,"work_area_bottom":1080,"work_area_left":0,"work_area_right":1920,"work_area_top":0},"window_placement_popup":{"bottom":940,"left":480,"maximized":false,"right":1440,"top":140,"work_area_bottom":1080,"work_area_left":0,"work_area_right":1920,"work_area_top":0}},"cached_fonts":{"search_results_page":{"fallback":[],"primary":["Inter"]}},"countryid_at_install":17477,"credentials_enable_autosignin":false,"credentials_enable_service":false,"default_apps_install_state":3,"default_search_provider":{"synced_guid":"485bf7d3-0215-45af-87dc-538868000005","synced_guid_private":"485bf7d3-0215-45af-87dc-538868000007","synced_guid_search_field":"485bf7d3-0215-45af-87dc-538868000005","synced_guid_search_field_private":"485bf7d3-0215-45af-87dc-53886800000

@Rhino_Cracker Apparently you need a JSON Editor.

@Pathduck said in Vivaldi asking confirmation to open uTorrent for magnet links:

Yeah, not sure if that would work. JSON is tricky and a small mistake would just mean the browser won't even start.
First of all it's a "minified" JSON so really hard to edit safely without a proper editor. I'd recommend you use this one: http://tomeko.net/software/JSONedit/
The "protocol_handler" is its own entry below the root, and you might have to add it yourself if not already there...
EDIT: If it's not clear from the lack of quotes around them - the values need to be boolean, not strings. Just found this out the hard way

burnout426

@Pesala Yeah, JSONedit in tree mode is what I like to use.

@madonnaragu This is highly experimental and not for unexpreienced users.
The code has to be added in file Preferences of Vivaldi Default profile folder.

We're looking into implementing this feature. It's now in our pipeline. When there's progress, we will update this thread.
