Suddenly I cannot access any of my banking accounts online as they all ask me to Enable JavaScript (have been using them all for years with FireFox0. Also, I cannot even use my Facebook account or log on anymore.

Everything is asking me to ENABLE JAVASCRIPT and I can find nowhere in FireFox 26 to allow me to do this?

Please help.

Yes, you can no longer do this in Tools > Options > Content.

That setting has been removed from the user interface, so you need to check the related javascript.enable pref on the about:config page instead to make sure it is set to true.

You can also check your extensions:

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

Wow, thanks so much guys, I entered "about:config" and scrolled down to turn it on to "true".

Works perfect now once again, I certainly do appreciate this very much as I was getting a headache trying to figure it out myself!!!
