Assigning this metabug to you, Scott. I'm starting to get into the RDB section of the Firefox spec. I'll post comments in this bug as I finish major sections. You should go through those sections and file bugs for work that needs to get done in FirefoxPerk so that it meets the spec. You'll probably end up filing both simple bugs and metabugs that block this bug. For instance, I recommend you file a metabug named "[Meta] Document navigation hotkeys" that blocks this bug. Then you would file separate bugs for all the key strokes blocking that bug. Same goes with document mode browsing, table mode browsing (already open, probably needs to be made meta with smaller tasks under it), etc.

lsr (Linux Screen reader) development has been stalled and it has been unmaintained for a few years now. Maintainers don't have future development plan so i am closing the bugs as WONTFIX. Please feel free to reopen the bugs in future if anyone takes the responsibility for active development.
