Hola, No hay problemas con la mayoría de las extensiones que tienes instalado, digo deberían seguir funcionando, pero ese error debe estar relacionado con los certificados root del Firefox: https://support.mozilla.org/es/forums/contributors/717137?last=88706#post-88701 ahora solo afectarían a versiones desactualizadas de Firefox, es como que tienes los certificados de Firefox vencidos, prueba volver a actualizar el Firefox saludos

Please verify them or just let me have them on my browser, they're tools I use daily and I find it very difficult to work without them.

You appear to have posted this thread with Firefox 136 yet the Extensions being disabled means you are using a older Firefox version that does no meet the minimum requirements as per https://support.mozilla.org/en-US/kb/root-certificate-expiration (there is no es translated version of kb article).

Basically you need Firefox 128 or later for the Extensions to not be disabled and to be able to install new extensions. Or if you are using Windows 7, 8, 8.1 or macOS 10.12, 10.13, 10.14 then you need Firefox 115.13.0esr at minimum though 115.21.0esr is the current update.
