Mozilla Thunderbird

CNET Editors' review

Despite perceptions to the contrary, the desktop-based e-mail client is not dead. Mozilla Thunderbird 3.0 is a serious reaction to the prevalence of Web mail, so whether you're looking for a strong desktop client, an Outlook replacement, or a powerful tool for managing archives and Web mail offline, Thunderbird can scale to your needs.

Outlook users will notice the speed and responsiveness of the program, which loads quickly, even when weighed down by multiple folders and RSS feeds, and the basic feature set remains intact: good junk mail filters, HTML support, multiple identities, and robust Web mail, POP, IMAP, and Microsoft Exchange server support. Security features include S/MIME, digital signing, message encryption, and a built-in phishing detector. Add-ons, based on the same code as Firefox's add-on network, can enhance your security even further.

Joining such useful features as the back and forward e-mail browsing buttons and customizable tags in version 3.0 are a set of must-have features. The powerful search tool integrates results with desktop searches on Windows Vista and Windows 7, while tabs reinforce the connections between Web browsing and e-mail reading. In fact, the new search tool is so powerful that if you have a massive number of e-mails, you may want to set it to index them overnight lest it drain system resources from other programs. Gmail support especially has been revamped, so you now get an All Mail folder in Thunderbird, among other improvements. Mozilla's new Personas skins work in Thunderbird, while the Lightning add-on supplies the missing Microsoft Exchange-compatible calendar feature.

Flexible, powerful, and lightweight, Thunderbird 3 is an appropriate companion to Firefox in every way.

New search and tabs take flight in Thunderbird 3:

    "Fantastic easiest install import of settings and email."

    September 6, 2012  |   By wwlaughlin1

    Version: Mozilla Thunderbird 15.0

    Pros

    Installed on a Win7 Laptop with a trouble free install! Imported all settings for email, and easily imported all email from Outlook! Had to reset my filters and I was in business!

    Cons

    Had to redo my filters! No real big deal!

    Summary

    As I had never used Thunderbird before I ws quite impressed!

    "This revies is for version 14..."

    September 6, 2012  |   By DaniRules

    Version: Mozilla Thunderbird 15.0

    Pros

    EASY to install
    Clean uncluttered screen
    Fast

    Cons

    None that I can think of.

    Summary

    I'm just an ordinary email user, I don't need anything fancy. All I wanted was an email link in my taskbar now that I have Win7.

    Downloaded eM Client and it would not send an email. Gone.

    So after reading the reviews for Thunderbird 15 I decided to search for Thunderbird 14 :) and I am VERY pleased so far. All I had to do was enter my email and password and it's working perfectly.

    I would have posted this on the version 14 page but could not find it again.

    "Not the Thunderbird I have been using for a long time."

    September 6, 2012  |   By Charles Bender

    Version: Mozilla Thunderbird 15.0

    Pros

    It started out okay... a little sexier interface, but somewhat Mac-like, with the faded looking tabs. Little did I know what was about to happen.

    My history with Thunderbird as a mail client has been stellar most of the time, but this may be the last straw, as mistakes go.
    Read the cons.

    Cons

    Every now and then this email client makes a bad move, but this one has been a really bad one for me. I try to keep my numerous mail folders cleaned and small, but now my inbox folder is corrupted, according to the Mozilla website. I get the same emails day after day... some can't be seen, but they keep returning, after numerous deletions. The cure is so complex and difficult to understand, it makes my neck hurt. But most of all, the advice doesn't tell you what has happened... only what MIGHT have happened, among the numerous possibilities. I didn't like Outlook Express, many years ago, so I switched to Thunderbird... now I want OE back again. I dislike the very idea of Facebook and Twitter, so this hurts my communications, since my POP mail provider is not much more reliable to use as webmail. Sometimes I can't even log onto their mail site.

    Summary

    I'm on Cnet looking for another email client, because troubleshooting and suggested fixes from Mozilla have made the program un-backupable... if that's a word. Essentially, I will be starting over, without my email purchasing log from 2007 through to today. Oh well... the various websites have order histories... now if I could remember all of those orders, to know where to look.

    "Performance hog, extremely slow"

    August 31, 2012  |   By tahleki

    Version: Mozilla Thunderbird 15.0

    Pros

    It has built in chat for Facebook and other messenger applications.

    Cons

    Once it updated to version 15, it became unusable. Performance was extremely slow, constant "Not responding" errors, upwards of 58% cpu usage and 520k memory usage. It slowed my entire laptop down. I reinstalled version 14 and now Thunderbird's performance is great again, cpu usage is down around 2% and memory usage is at 360k.
