Reset the page zoom on websites that look wrong: "View > Zoom > Reset" ( Ctrl + 0 (zero))

See http://kb.mozillazine.org/Zoom_text_of_web_pages See Font size and zoom - increase the size of web pages and Font size and zoom - increase the size of web pages and Change the fonts and colors websites use .......... If you increased the minimum font size then try a lower setting (default is none) as a too high value can cause issues like you described. Tools > Options > Content : Fonts & Colors: Advanced > Minimum Font Size Tools > Options > Content : Fonts & Colors: Advanced > "Allow pages to choose their own fonts, instead of my selections above" .......... If you need to increase (or decrease) the font size on websites then look at: NoSquint - https://addons.mozilla.org/firefox/addon/2592 Default FullZoom Level - https://addons.mozilla.org/firefox/addon/6965

Pages still do not load properly. There is a line that run through the middle of each page and you can see the tops of letters showing through. Font size is different on each and every page. I had already tried all of the suggestions that were given.

Can you attach a screenshot and post a link to that page?

Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (200 KB) and do not click Preview after you have attached the image.

Same issue - it started when I used the feature "zoom In - Zoom Out". Cannot get it back correctly even with the reset button.

Deleted all cookies - doesn't work

Deinstalled and re-installed FF - doesn't work.

What else?

Tools -> Options, "Content" section, click the "Advanced" button in "Fonts and Colors" area. In the dropdown for "Minimum Font Size" select "None"

The only thing I can come up with is that Firefox and Windows 7 just do not gel. Thank you for trying to help. I had tried that process previously with no luck. My PC is brand new, although my PC skills are not the best this is very frustrating.

I had overlapping sentences and cut off lines. Resetting minimum font size to "none" did the trick! Whew - thank you!
