Only Export works, and malicious Rated 1 out of 5 stars

In the filter management window, it adds a buttons to enable export of filters, however import doesn't seem to work. It can only import from "Becky internet mail".
It hijacks your internet browser to a .ru-based site, but it seems to have been resolved after removing the add-on and reinstalling the browser. Still too risky and cumbersome to just get half the solution. Considering abandoning Thunderbird, as it's not a long term viable solution. :(

Malicious. Don't install Rated 1 out of 5 stars

I installed this but didn't even get around to testing to see if it works. Immediately after I installed it launched a browser to the developer site, some tee-shirt name, which redirected to an Amazon page. I removed this immediately after that. Might not do anything else other than that advertisement but I don't trust it and don't feel like spending the time to see if that's all this is doing.

Worked really well - did exactly what it said on the tin for 5 email accounts. Saved me hours of work - very grateful that you have developed and made this available - thank you

Do not trust Rated 1 out of 5 stars

Does not work. Requires Google login when turned on for non Google email (this has never been asked before). Removing Thunderbird and reinstalling now. Should be removed from mozilla site. Used on Ubuntu 16.04

Works fine with SeaMonkey 2.46 Rated 4 out of 5 stars

Unfortunately information on add-on download page is very outdated. An additional flaw is that in add-ons manager under [More] you will find a link to no longer existing(?) domain "", if you click it you might be forwarded to really suspicious websites. May be this is meant by the Virus warnings in some other reviews? Panda Antivirus rates the add-on itself as virus free.

The add-on itself is useful, and a [Converted] version works fine with my unofficial (akalla) English SeaMonkey 2.46 (Windows NT 6.1; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0 Build 20160923004119 (Default Classic Theme) on German WIN7 64bit.

Import doesn't work on 38.2 Rated 1 out of 5 stars

Using it on 38.2 on Xubuntu. The import feature doesn't seem to work as the import wizard shows an empty field to select types from.

Important.Pour les nouvelles versions thunderbird.
Il faut afficher la barre de menus classique pour accéder au bouton "Import Filter".

Option ----> Barre de menus ----> ok
Filtres des messages ----> exporter
outils ---> imports de filtres

To katalyn08 - both export/import work as they should under TB 38.1.0 Rated 4 out of 5 stars

Export -> Tools -> Message Filters -> lower right Export Filters.
Import -> Tools -> right below Message Filters -> Import Filters.

Not fully working with thunderbird 31.7 Rated 1 out of 5 stars

I've made the export of the filters but I can't import them :(. I don't have this option.

Thank you very much

Worked great for me (TB 31.5.0). I missed the old one and really appreciate someone picking it up and making it compatible with the latest Thunderbird.


Does not work at all. Rated 1 out of 5 stars

Does not work with Thunderbird 31.X unfortunately. I could export my filters but importing them does absolutely nothing. Nada.

After hours of searching and reading and trying different people's suggestions (and after skipping by this add on at first since my first glance at it looked like it would be too hard to get working) I went for Import/Export Enhanced and now all my messages are finally converted and into my new mail setup! Once it worked it worked great though it took a few tries using different methods to get there. I can see why some people got discouraged and down rated it but I'd read enough of the different problems that have happened to others and those comments helped me to work my way to the right way for me. It might not be an easy ride but if you keep at it and search around (or ask around) you'll most likely get there.

I was exporting from Thunderbird and importing to Apple Mail and found the following method:

Once you've got the add-on installed (and Enabled) you can find the menu option to start it either under the Tools menu or in the popup menu when right clicking on 1 or more mailboxes. For my export/import I finally found that exporting as "Export all messages in the folder --> EML format" was able to produce a file that Mail was able to use to get all the messages in the folder versus some other options that failed to get them all. I did find that if there were mailboxes that were subfolders of other mailboxes and the top level (parent) folder had no messages that that folder nor the contained folder(sw) would be created. I don't recall if I ever got the contained folders exported at the same time as the containing folders since I had no containing folders with messages to find out. In any case, I just went back and imported the folders that didn't get imported and aimed the exported files of messages into the correct parents. Another issue was that each created folder had a subfolder called "Messages" and when I imported the dumped message files (using the Apple Mail format selection for the import) those extra levels of folders were created in my mailbox structure. So I had to drag and drop the complete set of a mailboxes messages from the "Messages" folder into the next folder up and delete the "Messages" folders. All this may sound crude and bothersome but believe me it was a joy to finally see mail moving to the new program! It may be obvious from the above but you can select more that one mailbox at a time to export (at least on the same level since I didn't try multi-level exporting at one time). The process just reminded me of how difficult things can be and I was glad to have a tool that at least did a very reasonable job for what I needed. I suspect much work went into it and the task being undertaken is a pretty messy one if one considers the number of email programs that might need exported and imported from and to. It's also shows that no one seems to put much effort into trying to make the job of exporting data from their system very easy (like finding the CANCEL button on a free trial site) since no one wants to make it easy to abandon their system for another. (I like and liked Thunderbird but after 8 or so years of it it was starting to mess up a little more than it had been in the past for me; and it's (non)integration with OS X was becoming annoyingly rough edged and not totally functional all the time.) The strange thing is that there seems to e almost as little care put into a program's import functionality as in the export which doesn't seem like it would draw in new users as well!?! But I think this add on is a noble and generous effort to create a tool to help us get by the design flaws of the mail transfer process.

If it doesn't work for you and you've actually spent some time trying a few different methods then it's too bad and I understand the griping but I wonder at that point if you can point to something that will work the way you want. I think there are some utilities that one has to pay for that may be easier though often they aren't any easier or don't ever work even after paying. I think my description above is a little disorganized but I hope that some of my hints aim a few people in the right direction. If you find the thing that works for you then write it up here to help others with this ugly task.

Does not work on Thunderbird 31.1.2. The export process was successful (as far as I can tell), but the import failed (no rules were imported) although it said that it was successful.

That being said, as other commentators have mentioned, the filters rules for any account are simply stored in a file called msgFilterRules.dat, that you can easily find in your TB profile folder. You can just copy that file into your new profile (and maybe you have to restart Thunderbird) and that's it, no extension needed.

This plugin does not work at all in version 24.6.0!!! What a waste of my time.

Rated 4 out of 5 stars

I'm using TB 24.4.0 and was easily able to use this to export my filters. I was a bit confused by the lack of a file type during the export process but figured out that the output is just a simple text file. Then I was able to find out that the filters used by TB are in the file msgFilterRules.dat in your Local Folders directory. It's quite easily edited or copied to another computer so the Export/Import function isn't strictly needed. Thanks for it though anyway.
