About QuickJava

QuickJava is a Firefox extension that allows you to easily enable/disable Java, JavaScript, Images, Flash and more directly from the toolbar and/or status bar! (Need help?)
NOTE: QuickJava will become obsolete with the release of FF version 57 and above and will no longer be updated. Please see this thread for additional information.

Problem opening Options dialog

Some users have expressed an issue when opening the options dialog. 

The message received is:
XML Parsing Error: undefined entity
Location: chrome://quickjava/content/options.xul
Line Number 6, Column 1:

Please post your OS and FireFox version here if you are having problems with options.  Also if you get a different error, please post the error message.

In the mean time you can get to the options by putting "about:config" (no quotes) in the URL box and then (click I Promise if it comes up then) filter down to "quickjava" (no quotes).  Double click on the preference that you want to change and when you're done just close the tab.


  1. Same error on two computers, Firefox 3.6, both Linux, one openSuse 11.2, other 11.1, Furthermore the plugin doesn't work, there are no icons on the status bar. I've tried to change prefs in about:config, no result.

  2. Same error with Firefox 3.6 and Ubuntu 9.04.

  3. Can somebody that's having this problem please contact me at: "Doug" then "07162" via gmail? (sorry for cryptic, trying to avoid spam). I'd like to send version 1.7 directly to make sure it's not fixed with that update already.

  4. Hello

    Is there a way to make enabled/disabled settings persistent between FF restarts ?

  5. Laurent, please see the third comment on this page:

  6. Tks for your help. I actually had a conflict between two different java updates installed ! I removed all of them and reinstalled Java from scratch. Everything is OK now ! Thanks again and sorry for bothering.

  7. Laurent, glad you got it working (since that means my extension is working fine, haha)

  8. Hey guys, not sure if it will work before it's approved but you can try installing from this link:


  9. Firefox 4.0.1 on 64-bit Windows 7. No error dialog or anything, but no options dialog either.
