Thanks for the heads-up.
Well guess I'll have to disable the auto-updating
option of FireFox for now until a reliable
long-term work-around arises for this.
I'm very surprised that HJ hasn't developed their
own system for dealing with these annoying
capture images. I mean the excellent JAWS v17 OCR
option could be modified to understand certain
capture images... couldn't it? Even some of the
audio alternatives are very hard to understand at times.

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
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 The only
alternative to Webvisum for solving image
captchas is a paid service called Rumola which
is a signed, third-party extension approved by
Mozilla, so it will work with Firefox 43 and
later. But the bottom line is
clear. Webvisumâs days are apparently
numbered. Maybe itâs time for the software
team at Freedom Scientific to give serious
consideration to adding a captcha-solving
feature to JAWS. Hope you guys find this
information helpful. For more information about
