Fixing Firefox PopUp Window Sizes

6:12:00 PM |

It’s not too often that I have reason to complain about Firefox, but I’ve had this annoying problem with pop up windows. As example, in my web editor I click the toolbar to insert a hyperlink. A secondary window opens where I can type the info except the window is so small I can’t even see the input field. I haven’t figured out what causes the issue, but I found several fixes. My feeling is this problem was triggered by one of those online support chat windows. I didn’t like them before and now I really dislike them. This is coupled by the fact that when you first search for a solution, you’re still in an agitated state and use search terms that challenge the family filter settings.
After I calmed down and tried a search without my swear words, I found three promising work arounds.

Solution 1: Change Your Firefox Configuration

The first solution came from Dave Austin who posted a video tutorial showing how to change one of Firefox’s configuration settings called:
dom.disable_window_open_feature.resizable.
To adjust this setting,
1. Open Firefox
2. Type about:config in the address bar
3. Scroll down the list till you find the entry. (See highlighted item in picture below.)
4. If the entry reads “false”, double-click the line. The value should change to true.
5. Close your browser

Solution 2: Use the Web Developer Toolbar

This is a good example of how when you’re frustrated you don’t think of some of the immediate solutions. In this case, I spotted a fix posted by Jon Gibbons on disappearing Firefox windows.
Jon’s solution is to install the web developer’s toolbar. As you might have guessed, I already had the toolbar installed, but never thought of using it to resize the second window. You can see the toolbar as Item 2 in the screen snap above. Rather than using the button, I right-clicked the popup window and selected Resize from the menu.

Solution 3: Use a Resize Bookmarklet

I didn’t try this solution which was mentioned on Jon’s site. He points to a java script bookmarklet from Nicholas Roussos. The idea is you select one of three sizes for the pop up window and save that code snippet as a bookmark. When you encounter a problem window, click the bookmark.
To use this bookmarklet, you will need to have checked Move or resize existing windows checked in the Enable Javascript section. I know some people prefer not having this item enabled for security reasons.
I suspect these solutions will solve your problem as they did for me. If not, you have my permission to swear.
