Web companies and services sometimes limit the dimensions of popups on their sites artificially with the effect that you cannot resize the window in your web browser.
We have already mentioned a configuration setting in Firefox to resize popups. In short: Users need to set the parameter dom.disable_window_open_feature.resizable to true for this in Firefox's advanced configuration window.
But fiddling around in the Firefox configuration is not to everyone's liking. The Firefox add-on Popup Resize introduces the same functionality as an extension.
The main benefit of using it instead of the configuration switch is that it works right out of the box and that it provides you with additional configuration options that you may find useful on top of that.
By default, the majority of unresizable popups should now be resizable just like standard windows in the web browser. Another popup annoyance is the limited interface they are shown in, usually without menubar, locationbar or statusbar.
The add-on takes care of that as well and adds the locationbar and statusbar to popup windows automatically. Users can furthermore add the menubar, toolbars and scrollbars (if required) to all popup windows.
It is on the other hand possible to remove all the bars from popup windows in the add-on options if you prefer that popups don't display any interface elements of the browser.
Popup Resize is a handy add-on for Firefox, especially for users who have to work on sites regularly that make use of unresizable popup windows.
Update: The Firefox add-on is no longer available. It appears that you have no other option than configuring the behavior in Firefox's advanced configuration window.
Here is how that is done:
Note that location, resizable and status are set to true already. This means that you should be able to resize popup windows in Firefox by default.
