my firefoz opens but opens a transparent window that only has the close,minimize and maximize buttons.
So my firefox has been running well but when i updated my computer, it stopped working. when i double click the icon, it opens a blank transparent window with only the maximize, minimize and close buttons. you cannot even tell its firefox. it does not display any error messages and installing again does not work. what is this and how do i fix it?

hello nachoz88, 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.
