Mozilla Thunderbird

CNET Editors' review

by: CNET Staff on December 08, 2009

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.

    "Instable, Cluttered"

    May 31, 2012  |   By 5735odra

    Version: Mozilla Thunderbird 12.0.1

    Pros

    Good for advanced user

    Cons

    Hanging to often, to complicated for average user, buggy.

    Summary

    After downloading and exploring eM client, I decided to give a review to Tunderbird. Using it on and off is to much frustration longing for simplicity, usefulness and look lead me to finally get rid of this email client from my comp. Love eM, now. Windows Live - same joke. uff...

    "Makes me appreciate Yahoo Mail"

    May 30, 2012  |   By seaweedsteve

    Version: Mozilla Thunderbird 12.0.1

    Pros

    Easy to setup STMP account for Yahoo mail.
    Free
    Add-ons
    Popular

    Cons

    -Slow.
    -Text sizing. It always seems to change text size in mid email. In Yahoo mail with this issue, I'd select all and then set to one size, 10 pt, say. In thunderbird it's a pain. It only gives me relative adjustments like "bigger"or "smaller".
    -New emails open in seperate window from Thunderbird.I want it to open in a tab. Should be the default instead it's not even an option.
    -If I'm composing an email on my own computer, why don't I just have a copy there?
    -I thought it would download all the mails and then I open them. Nope. One at a time. Click, fetch, wait, read. A lot of waiting.
    -Even slower to send and then to have a copy in my sent box, that's another process with attendant delays.
    -The buttons for dealing with the emails are in the middle of my page when using the preview pane, which I depend on. I want them at the top when controls should be. Why can't I move them?

    Summary

    Yahoo mail has gotten a lot worse lately. I was hoping that switching to a desktop client would offer speed advantages for reading emails where it could check my inbox and then have the mails all there when I start reading. NOPE. It's actually slower for reading and way slower for sending. I know about offline option for folders, but that's an ongoing hassle also. I spend a lot more time just dealing with thunderbird than Yahoo. Apart from that, well, I don't like the UI much and it's not easy to change like Firefox.

    It's just too slow and offers no advantage for a single account over online email. I think that Thunderbird could be good but the decisions, the group design is just not right for IMAP. Or maybe it's the archetecture. Don't, know, but after three weeks of tweaking and reading up and looking at add-ons, I'm dumping it.

    Updated on May 30, 2012

    Update, meant to say "easy to setup for IMAP", though I don't like how it deals with IMAP.

    Updated on May 30, 2012

    Another Con:
    Contacts open in another window. No viewing a column with your contacts beside your email. You have to go back and forth between windows.

    "Still the best"

    May 24, 2012  |   By pruther

    Version: Mozilla Thunderbird 12.0.1

    Pros

    Firefox lost its way a little while back, but now seems to be back on track. Speed has improved, memory use and leaks are down, and the diversity of add-ons can't be beaten. A much better browser than IE, and still for me better than Chrome.

    Cons

    None really. High quality browser.

    "Great replacement app for Outlook"

    May 19, 2012  |   By Minnesotafats

    Version: Mozilla Thunderbird 12.0.1

    Pros

    Easy to migrate Outlook files
    Very fast delivery of emails
    Intuitive

    Cons

    Writing replies not real easy, unless I haven't learned the tricks yet (minor issue).

    Summary

    My Outlook 2007 had become corrupt, locking up, not loading new messages, etc. Thunderbird so far has been a great replacement. Highly recommend.

    "Crashes attempting to get new mail"

    May 14, 2012  |   By rjrottawa

    Version: Mozilla Thunderbird 12.0.1

    Pros

    Nothing special to report.

    Cons

    Dld'ed ALL my emails from my ISP going back 3+years as if they were new. Then wouldn't download hew emails afterwards. Tried uninstall/reinstall; tried latest Earlybird version (14.0...). No Joy.

    Summary

    First time I've had to limp along with Win Live ID. Not a happy camper.

    May 9, 2012  |   By rogkal

    "A user friendly email program that is unsurpassed!"

    May 9, 2012  |   By baewyn

    Version: Mozilla Thunderbird 12.0.1

    Pros

    It does the job easier and better than any other available email program.

    Cons

    It still does not alphabetize the filters. Also, I found my filters have to be duplicated for Local Folder.

    Summary

    Great program for everyone. You are able to make it do almost anything. It would be appreciated if the filters could be alphabetized and apply to all Folders.

    "Excellent program spoiled by unfathomable crashes"

    May 4, 2012  |   By petesmithy

    Version: Mozilla Thunderbird 12.0.1

    Pros

    Tabbing, folder and search facilities.

    Cons

    Just one: unexplained and untraceable crashes. The web is littered with the berating of this fault which appears to be triggered by a clash with some other element but which Mozilla seems to wash its hands of. I never thought I would be beating a path back to Outlook as my local backup to Gmail.

    Summary

    Just hope that in a future iteration this might be addressed.
