I can not get FF 8 to resize the foreground window when I press ctrl + to zoom in, Is there a fix?

I am stuck with FF 3.6 because FF 8 does not resize the java script window properly when zooming in on a web page. See for an example web page.

Is there a fix?

I have tried disabling all add ons viewing with original default settings. Nothing seems to work. So I am stuck using FF 3.6 which is the last version of FF that works with Java.

That would make things worse for you.


Use Alt+SpaceBar to move or resize, especially if you have a problem grabbing edges of a window.

You can use JavaScript to resize windows with a bookmark, but there are severe limitations, see

Setting up:

  1. use about:config to change services.sync.prefs.sync.dom.disable_window_move_resize to false.
  2. Invoke bookmark anywhere but from the location bar which almost eliminates use of keyworded bookmarklets which was the most beneficial method. But there are ways of getting around that.

To invoke a keyworded bookmarklet from the location bar

  1. Bring up about:config
  2. "Ctrl+L" to back to the location bar instead of within Filter
  3. invoke your keyworded bookmark, which can include substitution
  4. return to your previous tab, Ctrl+W will close current tab

To invoke your keyworded bookmarklet from the Bookmarks sidebar, set up a folder with your resize bookmarks in it and include a Chrome URL bookmark for about:config

Name: ---about:config---- within resize folder containing Javascript resize/move

Location: chrome://global/content/config.xul


  1. "Ctr+B" bring up Bookmarks sidebar
  2. search on resize javascript
  3. invoke about:config in a new tab, Ctrl+click on the about:config chrome bookmark you included
  4. "Ctrl+L" to return to the Location bar
  5. invoke a resize bookmark from display in sidebar
  6. "Ctrl+W" to close the about:config tab, maybe you'll return from where you came from

All of my resize bookmarks have a keyword shortcut usually named by width, and can be seen in the following:

Thanks for the reply, but this fix is just slightly beyond my head. I can appreciate the customizable things for firefox.

However, I need java to work just like it does in FF 3.6 for me to use FF 8.

Is there anyway to do this?

the main point is that you do not resize the window, when you Zoom in or out, only the content is resized. See

To resize a Window manually you can grab any side or corner of the window and drag it to extend or compress the size.

In order to grab something move the mouse to the edge of the window, press down but do not release the left mouse button and drag the edge or corner to where you want it, then release the button.

If an edge of the Window is outside the screen area, then you will want to move it back by dragging on the title bar at the top of the window to move the window. If the window is too large you may have to make the window smaller before you move it.

If the top edge of the Window is above the screen area, such that you cannot grab the title bar, you will have to start with Alt+SpaceBar and "M" for move and drag the window with the mouse. The tricky part is to press the "Enter" key to release the grasp.

I just re-upgraded to FF 8 and the problem seems to be fixed on my laptop at least. I have not tested FF 8 on my 2 other desktops yet.

Also, I think I have tried grabbing the side of the window in a java app before without any luck. But I will try again and keep y0u all posted.

Thank you for your speedy replies. If the problem persists, I will try and post pictures (jpg) of the issue
