UPDATE: I have updated the extension to support the current version of Thunderbird (version 3.1).
What makes Thunderbird (TB) a kick-ass desktop mail client is its flexibility that makes it extensible through various addons/extensions and plugins.
One of my favorite extensions since TB1.5 was the Auto Zip Attachments, which automatically compresses (zip) attachments on-the-fly. This is especially useful for email messages sent with MS Excel or Word format attachments, wherein compression ratio are usually high. No more need to manually zip the files from the file explorer before attaching the same to email to save on bandwidth, which likewise translates to speedier file transfer.
Unfortunately, the developers of this extension appear to have forgotten about it and failed to update the same to keep it abreast of the new and more robust Thunderbird 3.0. It’s only compatible upto TB2.0. It seems that changing the max version in the install.rdf file is not enough. Instead, it involves editing further another file deep into the .xpi file, as described in one of the reviews for this extension.
Following the instructions from the reviews/comments on how to edit the .xpi file to make it compatible with TB3, I successfully installed the Auto Zip Attachments extension into my own TB install. I took the liberty to make that modified extension available here for everybody’s consumption. Download link below:
Download and unzip the file, then install to your TB3 desktop client. Would appreciate feedbacks for any problems or issues encountered. Hope we enjoy Thunderbird 3.0 more with this extension.
