What do you meant with overlapping? Is it stretch or something the layout?

its hard to explain but when i load something half of the page i opened before is still there it over laps

the writing over laps to hard to read it

Reset the page zoom on pages that cause problems.

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

• http://kb.mozillazine.org/Zoom_text_of_web_pages

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"

• https://support.mozilla.org/kb/Changing+fonts+and+colors

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.

• Default FullZoom Level: https://addons.mozilla.org/firefox/addon/default-fullzoom-level/

ive tried the fronts still not helping the graphics and writing is still overlapping

So, the above mentioned font settings have the default setting and you aren't zooming the page(s)?
