Fix register protocol handler for mailto links in Firefox and Roundcube

I recently played with Mailcow and also tried out SOGo briefly. After logging in, SOGo triggers a infobar message in the browser asking whether you want to set SOGo as the default application for mailto links in the browser. No, I just don't want to it at the moment. So I quickly clicked on "Not now". After a few days I then migrated my Roundcube and wanted to set it as the default application for mailto links, but no popup appears. Even manual calls via the browser console do not help:

window.navigator.registerProtocolHandler('mailto', location.href.split('?') [0] + '?_task=mail&_action=compose&_to=%s', “test”)

Resetting the page settings, cookies, permessions etc. does not help either. It turns out that Firefox saves the "hide message" in the permissions.sqlite file and doenst clear the entry or i dont know how. FF enters a mailto-infobar-dismissed for the domain there. I removed line with SQLite editor, restarted Firefox and tada, it works.

tl;dr:

Register mailto handler doen't work with Roundcube for a domain after the popup (infobar) has been clicked away? Removed the mailto-infobar-dismissed for the (sub-)domain from permissions.sqlite

Add password to .p12/.pfx-certificate

With following procedure you can change your password on an .p12/.pfx certificate using openssl.

Export you current certificate to a passwordless pem type:

openssl pkcs12 -in mycert.pfx/mycert.p12 -out tmpmycert.pem -nodes
Enter Import Password: <Enter no password>
MAC verified OK

Convert the passwordless pem to a new pfx file with password:

openssl pkcs12 -export -out mycert2.pfx/mycert2.p12 -in tmpmycert.pem
Enter Export Password: <Enter password here>
Verifying - Enter Export Password: <Enter password here>

Now you are done and can use the new mycert2.pfx file with your new password.

white-space: pre-warp don’t work at Internet Explorer

Today i noticed that our Knowledge Base looks ugly at Internet Explorer. It seems that he ignoring the following CSS attribute:

white-space: pre-warp

After a few test I found out, that by default IE use for intranet page the compatibility mode. OMG...

There are two ways to change this. First you can add a meta attribute the every page:

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

or you can use the Apache Module mod_headers which is my choise:
1. Change Apache2 Config to load the headers_module

LoadModule headers_module modules/mod_headers.so
  1. Change now the vhost.conf and add the Header
Header set X-UA-Compatible “IE=Edge”
  1. Reload Apache2
