Re: [orca-list] Firefox caching

[David Bolter <david bolter gmail com>]

 Hi all,

Regarding Firefox specific accessibility performance, rest assured the 
Mozilla guys (myself included) are working on it from the FF side, and 
with even more attention soon I hope. Joanie I'm hopeful some of those 
work-arounds can be removed already.

Web pages can be extremely chatty these days. Our browser accessibility 
engine gets called for pretty much every node removal, insertion, 
hiding, showing. and we walk a fine line between filtering out what is 
important which itself takes cpu cycles, and spamming the client with 
events; on Linux all these events must cross process boundaries.

It is a hard problem. Deciding when and what to cache on the client side 
is also tricky.

Cheers,
David
