Keeping Your Firefox Plugins Updated

How often do you update your browser plugins or check whether you have the latest versions? It is a chore that most people often overlook. Keeping your plugins updated to the latest version significantly reduces the risk of attack by malware, viruses, etc. that exploit flaws in older versions of the plugins.

If you are a Firefox user, Mozilla has created a Plugin Check page to allow you to check whether you have the latest plugins and to update your plugins by clicking "Update."

Using DavMail Gateway To Allow Thunderbird To Access Microsoft Exchange Server 2007 & Earlier

Your employer uses Microsoft Exchange and allows you to access your e-mail, calendar and contacts via Outlook installed on employer-issued computers. You want to access your e-mails, calendar and contacts on your own computer using a client such as Mozilla Thunderbird. Your employer refuses to enable IMAP access, citing security risks. Microsoft Exchange uses proprietary MAPI protocols, which are incompatible with the open protocols that Thunderbird and other clients use.

With IMAP disabled by your employer, you are forced to use the clunky web-based Outlook Web Access. What do you do?

Enter DavMail Gateway.

DavMail Gateway is an open-source POP/IMAP/SMTP/Caldav/LDAP exchange gateway that enables users to use any mail/calendar client (e.g. Thunderbird with Lightning or Apple iCal) with any Microsoft Exchange server.

DavMail Gateway's mechanism is deceptively simple yet elegant: it uses Outlook Web Access to retrieve your e-mail, calendar and contacts from your employer's Exchange server and then retransmit them to your local client using open standard compliant protocols (e.g., LDAP, SMTP, IMAP, Caldav, POP).

DavMail Gateway is compatible with Microsoft Exchange 2007 and earlier. It is written in Java and officially tested on Windows, Ubuntu and Mac OS X platforms.

Here is a visual schematic of how DavMail Gateway works:

I have tested the latest version of DavMail Gateway with Thunderbird 3 on my home computers running Windows XP and Ubuntu 9.10 to access my employer's Microsoft Exchange 2007 server at work and I am pleased to say that DavMail Gateway works like a charm, allowing the Thunderbird installed on my Windows XP and Ubuntu 9.10 systems to access my employer's Exchange 2007 server without any problems.

No more clunky Outlook Web Access for me.

NB: This method does not apply if you are accessing your e-mail through You can still use Thunderbird to access your e-mail. For detailed instructions, see my blog post: Accessing Your Outlook WebMail Using Thunderbird.

Changing your Domain Name System (DNS) to Open DNS or Google Public DNS

Most computer users use the default Domain Name System (DNS) that is provided by their Internet Service Provider (ISP). A Domain Name System is a network service that converts a web address (e.g., into its numerical equivalent (e.g., 123.345.567.789).

If you are dissatisfied with your ISP's DNS, you can define your own DNS either in your router's configuration screen or in your operating system's network preference. The two principal public DNS service that are widely used are:
Open DNS's IP addresses are:
Note: You do not need to sign up for an Open DNS account if you only want to use the basic Open DNS without additional services. You only need to enter the above two DNS IP addresses into your router's or your OS's network configuration.

Google DNS's IP addresses are:
Don't know how to change your DNS server? Google has easy to understand instructions. If you plan to use Open DNS's servers, use the two Open DNS's numerical IP addresses instead of Google's IP addresses.
