Hidden attachments in Thunderbird

Images and related content in HTML messages

relates to section: Thunderbird 5.0 – New Features and Changes#Images and links in HTML messages

Attachments in a “multipart/related” context (such as images inserted into the message body itself, but also items like PDF files which Thunderbird cannot display inline) are no longer provided in the attachment pane even if View → Message Body As → Plain Text is chosen [24].

A hidden preference mailnews.display.show_all_body_parts_menu has been introduced, which – if set to “true” – provides a new menu item View → Message Body As → All Body Parts. Select this to present all MIME parts of the message as attachments, which will be displayed if they can be shown inline unless View → Display Attachments Inline in unchecked. This allows to (a) save again embedded content from the attachment pane, and (b) access attachments in a malformed message which otherwise would stay invisible.

There is also an add-on [25] which can be installed to enable the additional menu point. It was mostly created for easier identification and documentation of that feature [26]. Note that the add-on won’t work in versions prior to 8.0.

This Thunderbird (v8.0) suddenly started losing attachments. They disappeared from old and new messages alike but not from all messages. Sometimes the attachment vanished right before the user’s eyes, a really impressive behaviour! Along with them the attachments indicating paperclip disappeared as well.

Research led me to the post above and the given solution actually worked for Thunderbird 8.

The missing paperclip in the mailbox view also reappeared, although it took a while and/or a couple of restarts and/or installing the mentioned add-on, not sure which, although uninstalling the add-on leaves the paperclip in place.

Twitter RSS feeds URLs & ID location

Twitter did it again 🙁

Implementing a platform-restricting policy, they first killed Friendfeed’s (maybe other aggregators’ as well) ability to post to Twitter. They also recently killed FriendFeed’s (maybe other aggregators’ as well) ability to receive input from Twitter accounts. And, somewhere down the line, they hid the link to an account’s and its lists’ RSS […]

Yahoo! Mail IMAP capability

It is possible to get direct IMAP access. Yahoo! operates IMAP and secure IMAP servers ( in particular), which are globally accessible. However they require a specific, non-standard IMAP command to be sent before login is done, namely: “ID (“GUID” “1”)”. This non standard command is not required if accessed from mobile networks, typically those […]

Apple and Google reward apps that have the ‘sticky factor’ | Technology |

“We believe the new ranking algorithm is now more complex, taking into account a measure of activity in the application and not simply new installs per day,” wrote Geoff Cook earlier this month for Business Insider. “In particular, we believe the ranking now considers either Daily Active Users (DAU) or the ratio of Daily Active […]

How to Get Thunderbird to Remember Passwords

No checkbox to remember passwords

It can happen that you will find no checkbox in Thunderbird to remember passwords. To change this, you will need to edit the prefs.js file, located in the Thunderbird profile folder.

Close Thunderbird and open the prefs.js file in Notepad or another editor (make a backup copy of prefs.js first, as […]

Improve conversations in Twitter: enter the ~tildetag

Twitter isn’t about conversation. It’s about broadcasting that there is a potential conversation happening.


I avoid following conversations in Twitter. The reason is simple: Doing so is hard and RTs lead to reading the same staff over and over. Plus, I can’t always actually read everything, as not everyone uses “reply” and I am rarely […] Ο κατάλογος με καταστήματα delivery φαγητού για online και τηλεφωνικές παραγγελίες Ο κατάλογος με καταστήματα delivery φαγητού για online και τηλεφωνικές παραγγελίες
