tips and tricks
Mozilla derived web and email clients, dropping self signed certificate support.
Late in 2014, many people noticed Firefox, Seamonkey, and many other derived products no longer allowed users to easily access content using self signed SSL certificates. Often simply reverting to older product version (i.e. pre-FF 31) restores ability to access self signed SSL encrypted web and email services. This apparently is deliberate as Mozilla Foundation will soon launch a free Certificate Authority (CA) in 2015, Let's Encrypt.
Mozilla - User Agent indentifier
For Mozilla family web broswers (Mozilla classic, Firefox, Seamonkey, Camino, ...) many of the browser identification attributes can be manually adjusted. Just browse to: about:config (may need to manually type this). Search for useragent.
general.useragent.extra.seamonkey default string SeaMonkey/1.0.2
If there is a web application that complains your browser is not compatible, try adjusting you browser identification string and see if works anyway.
SeaMonkey/Thunderbird - IMAP Folders
Avoid the dreaded "The current command did not succeed" message when creating sub-folders that contain other folders. Typically this can be seen when running SeaMonkey (a Firefox/Thunderbird mashup) under recent versions of Apple's OS X with client set to not allow folders to contain both messages and sub-folders.
The work around is to create two nested folders simultaneously using a forward slash.
This will result with a folder_a being a non-message containing folder, and folder_b a message only containing folder.
