- The report does not target exactly one problem
- The report is vague
- The report does not have a set of criteria by which it can be marked as FIXED, and it cannot be VERIFIED
I would have hoped that you would have read the bug-reporting guidelines first. You just wasted the valuable time of all people Cc:ed on that bug (and the time of another QA to come along and mark INVALID as VERIFIED).
The fact that seems to have passed you by is that everybody has some set of bugs that affect them, and this set differs from person to person. It's a pity your wife feels she cannot use Mozilla; but this is NOT the way to solve that problem. Pay for the bugs important to your wife to be fixed; fix them yourself. I'm surprised I'm having to explain the basics of how free software works to you !
I believe the thing with new accounts + the expert entry form is fixed now in current bugzilla running on bmo.
The simpler helper you describe would be a massive QA problem due to useless reports and duplicate reports. I think the current helper strikes pretty much the right balance. Mozilla wants motivated bug reports from users who don't know much about the browser itself, but are still able to distill a useful report.
I can't comment on your talkback suggestion, since I don't use talkback. It appears to be this bug. If it differs from that, file a new bug on this one issue. Or just use a non-talkback-enabled build.
btw, have you tried k-meleon ?
