trying to import from Dropbox Noté 1 sur 5 étoiles

as I stated below, I have Ubuntu 15.4, using latest TB v.38.3. I was able to export my emails to Dropbox using this add-on when I had earlier version of Windows 8.1 and TB 37, but hate Windows now (no privacy) migrating to Linux as are a few other thousand people.

I can open single emails at-a-time within Dropbox folder for TB, but I have thousands of emails and not going to spend time opening each email to discover or guess header source.

Why TB and FF got rid of this useful, necessary functioning tool is beyond me--ESPECIALLY when one has to change or upgrade to new computers or software. Unbelievable.

Thanks for Thunderbird Message Filter Import/Export Noté 5 sur 5 étoiles

I just installed this and it looks like it is just what I needed to archive some older emails from family and friends - I had been using a "webmail" solution for email and after the ISP deleting my email account for the second time (for not checking it often enough) i'm using Thunderbird to pull all my separate mailboxes together and now I can archive at my on pace thanks

An "Enhanced" version exists for modern TB Noté 4 sur 5 étoiles

There is a patched version of this, not a recommendation for or against, just a pointer for those not aware of its existence:

Help for actual versions of Firefox (Windows) Noté 1 sur 5 étoiles

The PlugIn doesn't work with actual versions of Firefox (some years ago it worked great).
On windows computers the rules can be found in msgFilterRules.dat.

Filter import in Mac missing destination Noté 1 sur 5 étoiles

I tried exporting message filters from version 9 in vista to version version 9 on mac but failed during import. I get the message that I am using a different file structure than the original export. The result is that all the filter destinations come out as empty as the tool cannot figure out where to put it. Both the source and destinations are identical except for Vista and Mac. Anyone one knows why this is happening.

How to use it? Noté 1 sur 5 étoiles

I would like to know how this extension works ... I would like to export all of my e-mails from Thunderbird, and i thought that this extension is going to help me, but i can not fine any "export" button or menu item to export my emails. Are there any instructions ?!?!

Works on 7.0.1 Noté 4 sur 5 étoiles

I made the tweaks to the .xpi file as described earlier, but in my case I set the max version to "7.0.*" (without the quotes) and I was able to import filters.

I only wish the developer would update this,

Peer's patched version worked with TB3 and TB6 Noté 5 sur 5 étoiles

Thank you Wind Li and Peer.
I tried the patched version by Peer with TB 3.1.13 on Ubuntu 11.04 and TB 6.0.2 on Windows XP.
It worked.

Exporting seems no problem. It always generates a text file containing the filter rules.
As for importing, only once, I got a trouble that the operation terminated successfully but nothing came up to the filter menu after rebooting TB. But, I guess it because the profile data had some inconsistency before importing. At that time, I copied a profile from the other TB and then started TB to import the file. Maybe I made a mishap when I copied the profile manually.

Other than this case, this plugin works as I hoped.
Two unimportant problem to me is:

(1) When you import a filter rule, the old rule in TB is erased or overwritten. If you want to them combined together, I guess you firstly need to export the current rule to a file and edit it with the new rule. It may be just a plane text file but I'm not sure.

(2) While the export button is located on the message filter window, the import button isn't. It appears on the pull down bar of the tool menu. I was confused a little -- "Huh? Where is the import button?"

But anyway, I'm happy now. Again, I say thank you to Wind Li and Peer. (By the way, I wanted to donate to the author but this page doesn't have a link to Paypal . So I submitted it via one of his other plugin pages.)

Missing EML export WITH full folder tree structure Noté 1 sur 5 étoiles

I am waiting for a really usable export+import function for years. Originally I expected such a feature in Thunderbird itself but I lost my hope. The Add-On here is far away from being good.

I sorted all my approx. 100000 messages into a folder tree with approx 1500 folders.
Now I want to export them in *.eml format. So that a folder in Thunderbird is represented by a folder in Win7 (Linux). The export should take place in one step (not by having to export each single folder one-by-one).
Unfortunately this important core task is NOT possible with this Import/Export Add-on.
I got no feedback from the author if he is willing to implement this (easy) feature or not.

So I am still waiting for a real usable import/export Add-on

Hi WInd Li.
Thank for the answer.

You need export it from one thunderbird instance and import it to another.

I tried it, I export and import next. But my filder windows stays empty... Sorry, maybe I misunderstood something.
