Work around for accessibility issue with FireFox 1.5 and OS X- tab focus

Upgrading to FireFox 1.5 was a great pleasure but for one problem. FF 1.5 dropped the user preference (accessibility.tabfocus) that enabled tab key access to form elements. Without this preference OS X users can not use the the tab key to shift the focus to check boxes, radio button, pull down menus or buttons. This really slowed me down. When I am filling out a form I like to keep my hands on the keyboard. Reaching for the mouse slows me down and frustrates me. But with the help of a few FF devotes I have learned a work around.


Create a text file named user.js in

~/Library/Application Support/FireFox/Profiles/xxxxxxxx.default


Add the following line to the text user.js:

user_pref(“accessibility.tabfocus”, 7);

There are several values available for the preference:

  • 1- Give focus to text fields only. (The default in OS X.)
  • 2- Give focus to all form elements except text fields.
  • 4- Give focus to links (and linked images) only.

Values can be combine to enable multiple behaviors

  • 7 = 1 + 2 + 4 Allows the tab key to shift focus to text fields, all form elements and links
  • 3 = 1 + 2 Allows the tab key to shift focus to any form element. This is my preference.

The most creative performance I have seen all year

This video is incredible. I am amazed by creativity that went into the conception and the disciplined execution.

Apple brings video to iPods and iMacs, but…

I haven’t seen one in person yet, but I sure like what I have read about the new iMacs and the iPods. Even though I don’t think handheld video will be much more popular than those handheld DVD players I do think buying videos through iTunes will be immensly popular. Especially whne Apple releases a device for displaying the video on your HDTV.

I am disappointed in the remote control. Why is it IR? IR is very old technology that requires a line-of-sight to work properly. With Griffin offerin the RF Air Click and Bluetooth built into the iMac I think Apple could have don a little better by using a more modern technology. A technology that doesn’t have such a history of frustrating people.

I skied for 15 years but…

Now, after 10 years of snowboarding I only snowboard. For the first couple of years after I switched I kept planning to snowboard and ski, but the snowboarding is so much more rewarding and enjoyable. I can’t remember the last time I skied.

FDA and Drug Approval Times

The Economist is one of my favorite magazines and I am quite happy I recently got subscriptions from both my mom and Jamuna.

This recent article just gave me an idea for reforming both the patent office and the FDA- tie approval/processing times to families of drugs or patents the government believes would benefit the nation.

In the case of the the FDA lifestyle drugs like Viagra, Allegra would take a back seat to drugs for the treatment of more pressing ills (Cancer, AIDS, ALS, etc.). I think this could reduce the appeal of blockbuster drugs and the cost of pursuing less profitable segments. The latter could be achieved by reducing drug approval time and thus lengthening the time the drug is on the market protected by patent.

For the patent office the I think the implementation is less clear. I would like to see some way to reduce the burden of frivolous and defensive patents. The feelings, at least as far as I can tell are, too many frivolous patents are being awarded. As for defensive patents I think they do nothing to foster innovation in and go a long way to stifle it- very much the opposite of the nations goals for the patent office. Perhaps patent applications proven to be under current development could be expedited over applications for patents not currently under development. Determining what counts as “currently under development” could be very problematic but multi year patent application approvals are also problematic.

BitTorrent Rocks

Tonight I used BitTorrent to download a Knoppix LiveCD. This protocol saved me more than seven hours of download time. BitTorrent took about 40 minutes. My ftp client predicted 8+ hours to download. I hope more organizations embrace this technology. I would love to see it built into a few browsers.
