SWF Decompiler converts Adobe Flash SWF files back into FLA format and SWF files created in Flex back to Flex sources, which can easily be edited in native Flash environment. Every group of objects such as morphs, shapes, texts, fonts, sounds, ActionScripts, etc. could be placed in separate FLA library groups. SWF Decompiler can extract all objects (images, sounds, video, shapes, text, morphs, etc) used in SWF files into various file formats.
Soiled is a Flash-based telnet client and terminal emulator, supporting both char-by-char and line-by-line mode. In line-by-line mode, it has some features that make it suitable for MUDs, such as aliases, macros, and hotkeys. Since it is implemented in Flash, it can be used from a Web browser.
CrutziPlayer is a standalone player for NPAPI-based browser plugins (e.g., Flash). It provides external, hardware accelerated fullscreen scaling using XComposite, Cairo, and XFixes. It's a good solution, for example, for playing browser games fullscreen on Linux, as it autodetects the original .swf content size.
Linterna Mágica is a user script that finds Flash video clips in Web pages and plays them with a browser video plugin. Found Flash objects are replaced with HTML <object> tags, which are processed by browser video plugin. Linterna Mágica uses regular expressions to support most Web pages, so first-time-visit Web sites should work with it.
WilsonTechnology Flash Applications is a collection of Flash applications that make your Web site more interactive, and help to build online communities.

Grab Downloading Flash Video is a Bash script designed to be called via a Linux GNOME Desktop custom shortcut key while a Flash video is playing in your Firefox or Chrome browser. The script attempts to find the file being downloaded, waits for the download to finish, and then copies it to a configured directory. Prior to Flash 10.2, it was easy to find the file yourself in the /tmp directory. But starting with version 10.2, this script is more useful because the file is deleted but internally still open. Note that this is not a universal solution. Some sites, such as YouTube, make it easy to find the URL of the Flash video file. In those cases you may have better success using a download utility such as 'youtube-dl'.
