I just reinstalled. It's not that. I read about this issue online with a fix using the about:config for firefox and changing a parameter, which did the job, but since most people will not be doing that I am looking for a fix for my websites to stop firefox from enlarging the images.
Any website I visit on Firefox, but since I have a reference with the websites I created is when I noticed how big everything is.
Found this and tried it, which worked, but doesn't make sense, so reinstalled FF.
Step 2: Change your global scaling in the about:config preferences editor.
(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste pix and pause while the list is filtered
(3) Double-click layout.css.devPixelsPerPx and change its value to 1.0 for Firefox 21-sized fonts in the content area.
