Main good news are:

• Fixed breakage due to getter/setter definition changes in latest Firefox nightlies.
• "[Middle Button Drag Down] gesture starts FlashGot downloads" checkbox in FlashGot Options window.
• Bug fix: Link Chooser not properly honoring its "Choose all items by default" checkbox (thanks BaptX for reporting).
• Fixed built-in download manager not working on SeaMonkey 33 and above (thanks therube for report).
• Fixed POST data being sent with preamble headers no recent browser versions (thanks MoSal for report and flashgot.user for patch).
• New custom download manager argument placeholders, courtesy of flashgot.user's patch: "RAWPOST" sends the raw POST upload data including its headers; "HEADERS" sends just the POST data headers.
• Added Folx 4 and 3 support as "Folx" (legacy support is kept as "Folx 2")
• Support for 5 additional terminal emulators on Linux (konsole, lxterminal, urxvt, rxvt, xfce4-terminal, thanks Mathias Bauer for patch)
• Fixed JDownloader 2 detection issue (thanks user).
• Updated Youtube support (thanks user).
• Graceful handling of invalid referrer URLs.
• Support for full encryption on https://flashgot.net/
• Terminal windows attached to Linux/OS X download managers are now paused on completion with "Press [ENTER] to exit...", unless you set the flashgot.term.autoClose about:config preference to a non-negative integer value, meaning the number of seconds to be waited before automatically closing.
• Several FlashGot Media capturing improvements (thanks user for patches).
• Customizable terminal/launcher for Linux/Mac OS X download managers: if a "flashgot-term" script is found in $PATH it gets passed a "FlashGot (number of links)" string as its first argument (to be used as the terminal title), followed by the actual executable with arguments.
• Updated fr & pl localizations (thanks Jack Black and Teo)
• More compatible and complete generic URL parameter redirector (grabs the "real" final URLs from redirects and trackers).
• Addresses of media content captured by FlashGot Media can be copied to the clipboard by right-clicking their menu entries (thanks GµårÐïåñ for RFE).
• Updated dfiles.eu (FKA depositfiles.com) preprocessing for batch direct link premium downloads (similar FlashGot-supported preprocessed file sharing services are fileserve.com, filesonic.com, hotfile.com, megaupload.com, netload.in, rapidshare.com, uploading.com, uploaded.to, ul.to, zshare.com).
• FlashGot Media toolbar icon placement can be customized also while no media is playing.
• Added recent folders autocompletion support to built-in save path chooser; just focus the text field or type in it to have up to 10 recently used download paths to be looked up (thanks Scott Merrill for RFE)
• Added suggested file name support for links diverted from the "Save as" dialog.
• Added private mode support when calling built-in download manager.
• Further accuracy improvements in the Middle mouse button + drag south gesture, which triggers either FlashGot Link or FlashGot Selection, depending on the context (can be disabled by setting the flashgot.gesture about:config preference to false).
• Improved oron.com preprocessing for batch direct link downloads (similar FlashGot-supported preprocessed file sharing services are fileserve.com, filesonic.com, hotfile.com, megaupload.com, netload.in, rapidshare.com, uploading.com, uploaded.to, ul.to, zshare.com).
• Batch download support for linksafe.me (other already supported link protection/redirection services are chooselinks.com, re-links.com, protectlinks.com, rapidsafe.net, relink.us, rsmonkey.com, hideurl.biz, ftp2share.net, rapidbolt.com, linkbank.eu, linkbucks.com, rsprotect.com
• Updated and enhanced batch download support for relink.us (other already supported link protection/redirection services are chooselinks.com, re-links.com, protectlinks.com, rapidsafe.net, rsmonkey.com, hideurl.biz, ftp2share.net, rapidbolt.com, linkbank.eu, linkbucks.com, rsprotect.com (WARNING: Feb 15 2009, the rsprotect.com web site is infected, don't open without NoScript enabled), link-protector.com, stealth.to and lix.in, urlcash.net).
• Download Studio support (trial download here).
• Improved FlashGot Options|FlashGot Media panel, to choose a distinct download manager for streaming media capture. Firefox's built-in download manager is recommended because it uses browser's cache whenever possible and supports name guessing, and it's set as the default for FlashGot Media on new installatios.
• Windows visual download managers are fully supported on Linux and Mac OS X through Wine and Darwine (tested with FlashGet and Orbit Downloader on Ubuntu 8.0.4). You can enable or disable Wine support by setting the flashgot.useWine about:config preference to true or false.
