FF started displaying badly formatted or corrupted pages: Why?

It really more of the formatting. It seems the pages have been coded wrong. Text does not fit into boxes for the text. Some items are behind others. Sometimes the text is huge. A lot of the time the text is squeezed together very closely in bold. The pages seem to work. I have enlarge and made small the pages, that does not correct the problem. I use FF on an iMac, but that is not the problem. This just started in the last couple of months. It does not affect the functioning of the software, just the visual presentation.

Re: FF started displaying badly formatted or corrupted pages: Why?

If you have increased the minimum font size then try the default setting "none" in case the current setting is causing problems.

  • Firefox > Preferences > Content : Fonts & Colors > Advanced > Minimum Font Size (none)

Make sure that you allow websites to choose their fonts.

  • Firefox > Preferences > 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.


You can do a check for corrupted and duplicate fonts and other font issues:

Thank you for your quick reply and assistance.

I checked all of the preferences in FF. All were set consistent with the information given.

I will follow this problem more closely and see if I can find out the cause.

I am sorry this did not correct the problem.

Reset the page zoom on pages that cause problems.

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