I use several sites that employ pop-ups. The default size is too small, so I have to manually enlarge each pop-up. How can I set the default size for pop-ups to a larger size. I don't want them maximized, just larger than the default.

Coding on the page that the popup is being opened from usually specifies the popup window dimensions. If dimensions aren't specified, Firefox is supposed to open the popup to the same size as the original window.

Any specific websites or web pages where you have that problem with the popup being too small for the content in the popup?

A pop-up should fit normally unless you are zooming images or text or increasing elements otherwise.


Reset the page zoom on pages that cause problems.

  • View > Zoom > Reset (Ctrl+0 (zero); Cmd+0 on Mac)

If you have increased the minimum font size then try the default setting "none" as a (too) high value can cause issues.

  • Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)

Make sure that you allow websites to choose their fonts.

  • Tools > Options > Content : Fonts & Colors > Advanced > [X] "Allow pages to choose their own fonts, instead of my selections above"

It is better not to increase the minimum font size, but use an extension to set the default page zoom to prevent issues with overlapping text.
