Fwd: Re: Fwd: Re: Rapid development leads to many incompatible AddOns

Wayne Mery
sorry, but I'm not familiar with this area. So I ask the following

How serous are these issues in the overall "accessibility" of Thunderbird?

And do we have bugs reports to address them? [1], [2]

[1] core bugs:

[2] TB bugs:

Correction:  I meant "top posting" rather than "top quoting."

To elaborate a bit, the incompatibility problems often seem to be
related to determining whether the screen reader correctly detects that
Thunderbird or Firefox is displaying HTML content.  If so, screen
readers typically turn on a browse or virtual mode automatically, which
includes many single-letter hotkeys for navigating among HTML elements.
  It is generally much less efficient to read HTML content without that
special mode.

Another common area of problems is the TB composition Window.  I think
TB is supposed to use iAccessible2 for full editing support via a screen
reader, but for some reason, screen readers are not harmonizing with
that iA2 interface, thus often making it difficult to edit the text of a
message accurately.
