Re: [orca-list] Firefox caching

[Jared Wright <wright jaredm gmail com>]

I feel this creates many more problems than it solves given the dynamic 
nature of the web in 2010. The screen readers that employ these virtual  
buffers find themselves  struggling with  buffers becoming  outdated  
due to Javascript   or other client-side technologies that modify  the 
document object model without reloading the page, which is the trigger 
for the   caching process used by these screen readers. Sluggishness 
notwithstanding,  Orca's foresaking the use of virtual buffers is one of 
its greatest advantages in my opinion, and I am confident there are  
more effective  ways to improve Orca's performance in HTML environments..
