Console Filter A text filter for the JavaScript/Error Console.

Console Filter helps you to find the relevant errors in the JavaScript (or Error) Console.

If you use JavaScript in strict mode (javascript.options.strict is set), it can get pretty difficult to find your own lapses and oversights. Console Filter gives you more control over the console, so that you can focus on debugging instead of digging.

The filter syntax is basically "Google Lite" The messages in the console are searched for all terms entered (AND search), but must not contain any terms preceded by a minus sign (NOT search). Terms inside quotations marks must be found in that order (exact phrase).

Additionally, there are a few special category filters:

• @js (JavaScript errors only),
• @css (CSS errors only),
• @xml (XML/XUL/XBL/HTML errors only), and
• @- (messages and strict warnings only).

These can be enabled through about:config (recommended for Firefox 1.5 and above).

The filter textbox can be focused (and its content selected) through the hotkeys [Ctrl]+[K] (as the Web Search bar - opposing to [Ctrl]+[L] for the evaluation field) and [Ctrl]+[Q].

The current filter is saved between sessions, as is a list of up to ten permanent filters. To add a filter to that list, confirm it with [Return]. To remove it again, just right-click on it.

Compatibility

Console Filter can also be installed in Mozilla Suite, Netscape 7/8/9, Flock, Sunbird, eMusic Remote, and Nvu; however this is for the convenience of the users of minority applications and no support will be provided if Console Filter does not work in these applications.
