Firefox

• Fixed: Rikaichan may get stuck displaying kanji only after using the shift key.

• Fixed: Hotkeys not working in Firefox 3 (release).

• Fixed: Popup not displayed in Firefox 3 RC1. Note: Firefox 2's error console (Tools->Error Console) may show "Warning: Unrecognized chrome registration..." because of this fix. You can safely ignore the message.
• Fixed: Max copy/save settings didn't work correctly.

• Added support for text/plain (*.txt) files.
• Added support for ALT/TITLE attributes (image descriptions, etc.). Thanks to Seth D. for his help.

• Firefox/Thunderbird 1.0 is no longer supported.
• Pressing the "A" key while the popup is displayed allows you to move the popup to the upper-left or lower-right of the screen.
• Pressing the "C" key while the popup is displayed copies the contents of the popup to the clipboard.
• Pressing the "S" key while the popup is displayed saves the contents of the popup to a file.
• A "brute force" search of the dictionaries is now possible in the LookupBar. This is slow, but does allow you to perform, for example, simple English -> Japanese searches, and partial word searches. Asterisk * (narrow or wide) may be used before or after the word to indicate that the text may begin with anything or end with anything. A more complex regular expression can be used if you type : (colon) before the expression.
• Updated icons, thanks to Mark James's icon collection (http://www.famfamfam.com/).
• New color schemes.
• More customizable options.
• Lots of internal code cleanup and voodoo.

• Fixed a problem in preferences that prevented the display of some options.
• Fixed version information to make it work on Firefox 2.0b2+.
