Following the localisation of AttachmentExtractor, it will work fine with the following language versions of Thunderbird:
If you run Thunderbird in a different language than those listed there then this extension may not properly work with your installation. Localisation (translation) is now carried out through a great project called BabelZilla and their online interactive translation system called "Web Translation System". Its really easy to do so if you can read and translate the extension into any other language that isn't on the list join up there and get translating!
Once installed, just select the messages containing the attachments you want to extract, right click, and select 'Extract Selected Attachments' from the context menu. This will extract all the attachments from all the messages you have selected to the default Thunderbird download folder. If you want to choose the destination this time, select 'Extract Selected Attachments To..." to save to a folder of your choice. You can also access these functions from the 'Tools' menu in a 'Extract Attachments' submenu. There is also a Toolbar button you can add which gives you one-click extracting - left click to extract selected to default; right click to extract selected to a specified folder.
Please see the Changelog for a full description of changes and feature additions/changes.
Even though this project has reached the 1.0 milestone it should still
be regarded as inherently a work in progress. Most of the functionality
is achieved by leveraging existing Thunderbird functionality in a more
efficient way, so it should be safe. Some of the functions involve
modifying your emails, but warnings are displayed as appropriate.
In summary, I take absolutely no responsibility of the actions of the add-on, either unintended or otherwise and my liability as the author is limited to the amount your paid to get the add-on (i.e. £|€|$0).
The add-on is available via the Mozilla organisation, directly from AMO. AttachmentExtractor, like all add-ons now, requires Editor approval so updates are available a time afterwards - normally about 5-10 days.
From version 0.9.5, (previous versions had different strategies), the
first time you run Attachment Extractor the extension loads a window
with cut down version of the changelog on this website. To do this a
page is loaded with the extension name and version as parameters (so I
can display the correct version).
I don't collect any information off you or your Thunderbird installation/profile, personally identifiable or otherwise.
All the source is freely available in the XPI if you don't believe me.
If you are of a paranoid disposition then put on your tin-hat and make sure you aren't connected to the internet when you first use Attachment Extractor. Once the preference
attachmentextractor.firstuse is set to the current version number of the extension
then no further contact will be made.
Or I suppose you could edit the extension yourself or the default preferences file.
