With the release of version 26 of the Firefox browser, Mozilla has implemented a plug-in activation scheme that had been hinted at back in September 2013. The new version of the Web browser makes Click to Play functionality for Java plug-ins the default behavior, requiring you to click an applet on a Web page to authorize Java to run. Previously, Mozilla had promised to make this the default for all plug-ins, save for the most recent version of Flash, but only Java gets the treatment in Firefox 26. The update also adds support for script-generated password fields, improves page load times by not decoding images that aren’t visible, and fixes the AudioToolbox MP3 backend for Mac OS X.

Enabling Auto Spelling Correction in Snow Leopard
In Snow Leopard, the automatic spelling correction in applications is not usually activated by default. To turn it on, make sure the cursor's insertion point is somewhere where text can be entered, and either choose Edit > Spelling and Grammar > Correct Spelling Automatically or, if the Edit menu's submenu doesn't have what you need, Control-click where you're typing and choose Spelling and Grammar > Correct Spelling Automatically from the contextual menu that appears. The latter approach is particularly likely to be necessary in Safari and other WebKit-based applications, like Mailplane.
