I am unable to change my "mailto" selection to Runbox, please help

Question

I want my email preference to be runbox but the "mailto" menu won't let me select this. How do i fix this?

Answer 1

There are two possibilities:
# Add a custom handler to Firefox's options dialog
# Use (create?) an add-on which detects email links in pages and fixes them up with that link
To try #1, first open up your mailbox on runbox.com.
Check the domain name in the address bar: is it just https://runbox.com/ or is there an additional element such as www or mail in there? You may need to adapt step 2 to match.
(1) Below your inbox, open Firefox's Web Console using any of these:
* Command+Alt+k (Windows: Ctrl+Shift+k)
* "3-bar" menu button > Developer > Web Console
* Tools menu > Web Developer > Web Console:
The Web Console usually appears across the bottom part of the tab.
(2) Type or paste one of the following next to the caret (»):
(no www version)
navigator.registerProtocolHandler('mailto','https://runbox.com/mail/compose?folder=Inbox&to=%s','Runbox');
(www version)
navigator.registerProtocolHandler('mailto','https://www.runbox.com/mail/compose?folder=Inbox&to=%s','Runbox');
Then press the Enter or Return key to execute it.
An infobar should open at the top of the page (between the toolbar area and the page). Click "Add Application". You now can close the Web Console using any of the same methods you used for opening it.
If the infobar does not open and the Web Console displays "Not allowed to register a protocol handler for mailto" then:
* In a new tab, type or paste about:config and press Enter/Return to open the preferences editor. Click the button promising to be careful.
* In the search box that appears about the list, type '''mailto''' and pause while the list is filtered.
* If '''network.protocol-handler.external.mailto''' is bolded and user set to false, double-click it to toggle its value back to true.
* Switch back to your Runbox tab and start this step 2 again.
If you get a different error, please report back on what it is.
(3) Assuming the handler is added successfully: Open the Options/Preferences dialog as usual:
* "3-bar" menu button > Options > Applications
* (Mac) Firefox menu > Preferences > Applications
* (Win) Tools menu > Options > Applications
In the search box above the list, type or paste '''mailto''' and pause while Firefox filters the list. On the right-side dropdown, you should now find an entry for Runbox.
Success?
Does it work?
