Hi, David. This is not a problem. It's a security issue. To Temporarily Make Unsigned AdOns Work In Firefox:
For those of you who depend on Webvisum to solve image captchas in the absence of sighted help, read on. The recently-released Firefox 43 introduced a new feature that blocks unsigned third-party add-ons like Webvisum and prevents them from working. So if you update to Firefox 43 either intentionally or accidently, Webvisum will no longer work unless you apply the temporary work around described below. This is only a temporary fix that will no longer work after Firefox 44 is released early next year, because this work around will be disabled or unflagged in Firefox 44. And if you buy a new computer next year after Firefox 44 is released and then download and install it, Webvisum will no longer work at all, no matter what you try. So if you still have an older version of Firefox with a working version of Wevvisum already installed, do not update to Firefox 43 or else Wevvisum will no longer work unless you apply the temporary work around described below. The reason that Webvisum no longer works starting with Firefox 43 is that Mozilla now requires all third-party add-ons to be signed to comply with their security standards. Unfortunately, Webvisum has not been maintained by its developers for years, and they no longer even respond to email inquiries. So Webvisum is an unsigned add-on that is not approved by Mozilla. If you do update to Firefox 43,you can get Webvisum to work by following these steps: 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 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 key 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 6. Press Control-W to close the Firefox window and then relaunch it. Webvisum should now work.

Hi list members, I'd like to know whether the problem of webvisum not working with the latest version of firefox has been fixed yet? I'd like to let firefox know of this problem but I'm not sure how I would do that or if they would be able to respond to this request in a timely manner. Thank you for any information that you might have concerning this question. __________ Information from ESET NOD32 Antivirus, version of virus signature database 12880 (20160116) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 12880 (20160116) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
