Firefox 43, the latest version, introduced a security feature that prevents unsigned, third-party add-ons like Webvisum from working. If you depend on Webvisum to solve image captchas like many of us do, follow these steps to get it to work with Firefox 43:
1. Open Firefox 43 and in the address bar, type the below line as seen with no spaces: about:config 2. You will get a Firefox warning saying: 'This may void your warranty.' Click on the button that sardonically says: 'I'll be careful, I promise.' 3. tab once to the list of 700 or so items and press the letter X. You are looking for the below item: xpinstall.signatures.required 4. When this item is highlighted, press the context keyh or right click and choose toggel or press T (same thing.) 5. The highlighted value should change to false as in: xpinstall.signatures.required;false Then press control + W to close the window and when you run Firefox again, Webvisum should work.

I don’t use Firefox often, but I do use it especially for capchas. I think I am running the latest update now, but it tells me that WebVisum could not be verified for use with Firefox and has been disabled. How do I get this back or allow it to run? Jean
