[orca-list] General lag in Firefox 81

[Nick Wood <nick microlitesoftware co uk>]

Hi all,

Has anyone else noticed a general lack of responsiveness when tabbing 
through pages in Firefox within the past month?

It doesn't seem to be as snappy as it used to be.

Firefox 81 on Fedora 32, Orca master.

If I remember it was a Firefox update rather than a change to Orca that 
caused it - but it took me a few days to realise that web pages weren't 
as snappy to move around as they used to be.

I have no idea how to install an older Firefox version to see if that 
makes a difference - but happy to provide any further debug info if this 
would help.

In terms of reproducing it, just tab through the elements of a web page 
and observe the delay between each element being spoken.

Then go into another application, such as Thunderbird, and observe that 
when you tab from control to control Orca responds almost instantly.

Regards,

Nick
