I can not figure out how to copy and paste, the instructions said to open the user.js file in my profile directory but there is no such file. How can I fix this?

I searched the site for a fix but the instructions weren't very clear about inserting files and lines. I could not find the user.js file and i was not sure how to create a file, but i could create a folder. Could I use a microsoft word file or what?

I had this problem yesterday. Uninstalling the WOT (Web of Trust) add-on fixed it.

I do not have the Web of Trust add-on.
