Chosen solution

hello jay25, from another user we found out that this might be related to malware active on your pc. please close all firefox windows and try running firefox in safemode (by pressing the shift key while you're starting it). in firefox safemode go to firefox > addons > extensions and remove the entry named "Codec v1.0" or any other addons that look suspicious & you have not installed intentionally. afterwards see if you can run firefox normally again...

please also do an in-depth scan of your system with the security software already in place and/or a different tool like the free version of malwarebytes & keep firefox and your plugins up-to-date in order to stay safe on the web.
