some sites' appearance truncated views: e.g., Amex site = overlaps "boxes" [data fields]. not so w Chrome
A vew sites, such as American Express, open in a manner that does not allow complete data fields to appear and/or boxes containing text ovrlaying links to appear completely. these "boxes" cut-off portions of the text and/or ovrlap each otherrendering it impossible to read the text due to text of one box being superimposed upon text of an adjacent box.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
Try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

If you have increased the minimum font size then try the default setting "none" in case the current setting is causing problems.
- 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"
You can use an extension to set a default font size and page zoom on web pages.
