Firefox Popup Window Resize

For some reason, some popups in Firefox have been opening with the wrong size for the content displayed and the resize feature was disabled for the windows.

After some research, I found that in Firefox you can override this behavior by changing one of the many user preferences.

To do this

  1. Type about:config in the location bar and press enter

  2. Search for the "dom.disable_window_open_feature.resizable" entry

  3. Change the boolean value from false to true

Setting this to true will prevent a window from disabling the resize feature.

    Excellent suggestion.
    This pop up window limitation has been bugging me for some time. Your solution works!!

    Thank you so much.


  2. Thanx a million! I've been bothered with this for quite some time, and just about every other popup is not sized properly.

    I couldn't bother to rumble through about:config myself - lazy ass I am, but just a couple of minutes ago I encountered a popup-image-gallery (of a MP3 player I want to buy) which was impossible to view, and I needed to se the damn pics! Thanks again.

  3. This is very useful, thanks! I just wish they'd fix Firefox so the popups come out the right size in the first place! I've never experienced this on Internet Explorer and I hate the fact that it does something better than my beloved Firefox!

    I found this page with Google after I discovered (today) that a pop-up of 290px by 340px on my website is now "popping up" 322 by 380. What's going on?

  5. did a search on google for "how to resize pop up windows in firefox" - found your suggestion and it solved the problem. I wish I would have googled it long before now it would have saved much frustration.. super thanks!

  6. Thank you, found you through a Google search. I love Firefox, but I also love pop-up Blogger comment windows. Now the frustration is gone! :)

  7. Thanks x millions for the solution for this annoying problem!

    Worked like a charm :-D

    Is this pop up fix for Windows only?? What can Mac OS X users do??

    I am able to resize the pop-up windows-- the issue I have is the the popup window does not display all of the content-- it cuts off whatever is at the bottom-- is there a way to fix this? Not to be pesky, but it is beginning to get annoying that I have to resize the windows all the time! We use SchoolCenter for our school's webpages, and each function (like adding an image, editing text boxes, etc.) opens in a new pop-up window, so I am constantly resizing!
