some images and script are elongated and runny
Some script and images on Yahoo home page using Firefox are showing elongated and "runny" looking (if you saw The Matrix... that's what images and script look like).... not all tho. then they might clear up but further down the page is another that looks the same. Some kind of loading problem?

PS.... script looks like a bar code...
Hi elizjo8, Firefox 49 has an incompatibility with some older graphics card/chipset driver software. Some users have reported that switching between tabs will cause Firefox to fix the display, but that's obviously not convenient.
A bug report is on file (bug 1304360). You can help the developers working on the patch by providing some information about your current Graphics software (see below). Then try to fix it by updating your graphics software, or if necessary, work around it by turning off Firefox's use of hardware acceleration. Here are the detailed steps:
Your Current Graphics Software
You can copy/paste this info from the Troubleshooting Information page. There are 3 different options for opening that:
- "3-bar" menu button > "?" button > Troubleshooting Information
- (menu bar) Help > Troubleshooting Information
- type or paste about:support in the address bar and press Enter
On the left side, click the Copy Text to Clipboard button. Then paste into a new reply here:

Before posting, please skim down and remove any lines that contain your email address or any other sensitive information (usually there isn't any, but just in case). You also can delete all the lines about printers if you like.
Updating Your Graphics Software
This article suggests safe ways to check whether graphics card/chipset driver updates are available for your system: Upgrade your graphics drivers to use hardware acceleration and WebGL. Unfortunately for some older systems, updates are just not available.
Working Around Incompatible Graphics Software
Option #1: Targeted Change
This should have the least performance impact, if it works:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.
(2) In the search box above the list, type or paste d3d and pause while the list is filtered
(3) Double-click the layers.allow-d3d9-fallback preference to switch the value from true to false
You might not notice any change until the next time you exit Firefox and start it up again.
Option #2: Disable Hardware Acceleration
This is a common way to bypass most graphics software incompatibilities, but may cause fonts to appear spindly and poor animation performance.
"3-bar" menu button (or Tools menu) > Options
In the left column, click Advanced. On the right side, with the "General" mini-tab active, uncheck the box for "Use hardware acceleration when available".
This takes effect the next time you exit Firefox and start it up again.
