Bringing SIMD to JavaScript

Thu, 10 Jul 2014 09:04:40 +0100

In an exciting collaboration with Mozilla and Google, Intel is bringing SIMD to JavaScript. This makes it possible to develop new classes of compute-intensive applications such as games and media processing—all in JavaScript—without the need to rely on any native plugins or non-portable native code. SIMD.JS can run anywhere JavaScript runs. It will, however, run a lot faster and more power efficiently on the platforms that support SIMD. This includes both the client platforms (browsers and hybrid mobile HTML5 apps) as well as servers that run JavaScript, for example through the Node V8 engine.

HTML5 Flash Player (Shumway ) landed

Wed, 02 Oct 2013 09:19:23 +0100

Today Shumway landed in the Firefox codebase. Shumway is a way to support playing Flash (SWF files) without the Adobe Flash Player.

The Adobe Flash Player has been plagued with bugs so being to play Flash without the normal player is a big step forward for security.

Shumway is an HTML5 technology experiment that explores building a faithful and efficient renderer for the SWF file format without native code assistance.

Shumway is community-driven and supported by Mozilla. Our goal is to create a general-purpose, web standards-based platform for parsing and rendering SWFs. Integration with Firefox is a possibility if the experiment proves successful.

Intel Labs has a new project out Parallel Extensions for JavaScript, code named River Trail. River Trail brings the processing power of Intel’s multi-core CPUs and their vector extensions to web applications.

Addon development is back

Thu, 11 Feb 2010 18:51:55 +0100

For a long time I simply just didn't have the time to do development on my addons.

I've created 6 addons and some are fairly popular.

Linky which is the most popular one just passed 620.000 downloads and has more than 35.000 active daily users. Linky enables you to quickly open multiple links. You can also download, validate, copy and bookmark multiple links. All in one click.

Launchy which enables you to open links in other applications has around 23.000 daily users and more than 380.000 total downloads.

Firefox on Playstation 3?

Thu, 19 Nov 2009 20:58:17 +0100

There's a rumor out that Sony is looking into bringing Firefox to the PS3 platform:

"We recently received a tip from a source very close to Sony who says that they have been in talks with Mozilla lately about possibly porting firefox over to the PS3. That said, our source made sure to point out that they were unsure if any deal had actually been reached at this point, but it is great news none the less considering the complaints Sony has been getting about the lack of reliability with their current built in PS3 web browser."

about:memory landed

Sun, 04 Oct 2009 17:18:13 +0100

I'm here at EU MozCamp 2009 in wonderful Prague, and just saw that the about:memory feature landed on trunk.

I had the chance to talk to Vladimir Vukicevic, how implemented the infrastructure for it, and he told him that this is just an initial landing. The about:memory is not yet finished and it can and will be improved in loads of way.

The final/ultimate implementation will include data for how much memory JavaScript, images, etc takes up.

Can this be done? Links in same tab, links from external apps in new tab

Fri, 18 Sep 2009 14:43:46 +0100

I'm trying to figure out a way to achieve this:

1) I want links to open in the same tab. So if I click on a link that has target=_blank or target=_new in my Mozilla Firefox I want them to open in the same tab. Popups I want to open in a new window.

2) I want links from external applications to open in a new tab but same window. So if I click on a link in my mail program I want a new tab to open with the link so that I don't loose data on the current tab.

HOW HOW HOW do I do that?

If I set "" to 1 which means "Open links, that would normally open in a new window, in the current tab/window." it fixes problem 1 but not problem 2

Thunderbird can now auto config your account

Tue, 28 Apr 2009 19:35:18 +0100

A couple of days ago the first big part of the auto detection of mail accounts landed in Thunderbird. I've blogged about the feature before.

This means that you no longer have to enter all of the technical information to add an account. Just enter your name, email and password and Thunderbird will try to auto detect the rest.

Really really cool. Unfortunately it doesn't support Google Apps :(

Click on the image to see the full screenshot:

All of my domains, both personal and at work, are using Google Apps. But the new auto detection cant detect my setup. Damn. It sounded so cool.

My domain at work is which is hosted by Google Apps. The IMAP is at, but Thunderbird doesn't find that since it doesn't do any DNS lookup.

Hopefully this get fixed later...

What 99% uptime means

Wed, 15 Apr 2009 23:38:04 +0100

If your site's uptime is:
99% - it's down 3 days, 15 hours, 36 minutes
99.9% - it's down 8 hours, 45 minutes, 36 seconds
99.99% - it's down 52 minutes, 33 seconds
99.999% - it's down 5 minutes, 15 seconds
99.9999% - it's down 31 seconds
a year. Pretty interesting...

Open Source software in the public sector

Tue, 24 Mar 2009 23:50:28 +0100

Last Thursday the "Videnscenter for Software" held a conference on "Open Source software in the public sector." And Mozilla was represented at the conference.

I've heard about the conference and learned that you could ask for a free pass for the conference. Instead of only getting the free pass, I also got the opportunity for Mozilla to have a booth at the conference.

So Mozilla shared a booth with Ubuntu and I organized to get some merchandise from Mozilla Europe (big thanx!), so we got both posters, badges etc.

I also had my laptop running some Mozilla Firefox promotion videos, which is so much better than just normal slides. The videos I used are the ones from Hopefully there's gonna be more of these videos.


We, Hansen from Mozilla Denmark, and I, attracted a lot of attention. Most people already knew Mozilla Firefox and a lot of them actually ran it at home.

At the conference we also meet up with Christian Sejersen from Mobile Firefox. He brought along a Nokia N810 device with the latest Fennec beta on it. Walking around showing the mobile version of Mozilla Firefox also attracted a lot of interest.

By the way. Now I'm also an official part of Mozilla Denmark. A couple of years ago, I thought I was Mozilla Denmark :)

The Mozilla Firefox marked share in Denmark is very low. Denmark is Microsoft territory. So perhaps events like this can be a way to change that.

JPEG decoding will be 15% faster on x86_64

Wed, 28 Jan 2009 22:48:53 +0100

Just a quick note about a cool improvement that is gonna hit x86_64 builds of Mozilla Firefox soon:

"Currently, JPEG SSE2 code is only Windows x86. I will add it for x86_64 platform. After adding it, JPEG decoding is 15% faster."

7 untold secrets about me

Fri, 16 Jan 2009 20:44:15 +0100

(image) The seven, perhaps unknown, things about Henrik Gemal.

I was tagged by Fabien Cazenave who started to learn XUL by tweaking my Launchy extension. Cool!

So here are the rules to this:
1. Link to your original tagger(s) and list these rules in your post.
2. Share seven facts about yourself in the post.
3. Tag seven people at the end of your post by leaving their names and the links to their blogs.
4. Let them know they’ve been tagged.

Here we go:

1: I've been charged with importing pornography into India
When I worked in India I was contacted by a Danish company that sold CD-ROMs (back in the days) and they asked me if I wanted to help them get into the Indian marked. No problem. Send me some CD's and I see what I can do. Unfortunately there were some porn CDs among the CDs they sent. Don't know if I can return to India...

2: I was the top Bugzilla bug reporter
When Bugzilla was at 100.000 bugs Asa Dotzler pulled some data out of Bugzilla. We were 10 people that filled over 700 bugs each and I was at the top with 1764 bugs and Seth Spitzer was second. Read the article.

3: I played a lot of AD&D when I was younger
I loved playing Advanced Dungeon & Dragons. Still dream about creating another adventure and play again.

4: I played soccer for almost 20 years
We were once at the Danish national championship and became number 7. We also had a cool sponsor so I meet a lot of the top soccer people from the 90' like Ruud Gullit, Frank Rijkaard and most of the Danish stars like Preben Elkjær, Frank Arnesen and Morten Olsen.

5: I lived in India for more than a year working for a Indian advertising company
(image) What an experience! Quite amazing. I saw things that you can only dream about. Everything for dead poor people and filty rich people like I never seen before. Read my Indian story.

6: I have visited 35 countries or 15% of all countries
I love traveling. My wife and I did a lot of backpack traveling before we got our first child. Backpacked around in Thailand, Laos, Peru and Bolivia. See my map.

7: I have a road named after me
(image) In the town of Kirkeby on Fyen in Denmark there is a road called Gemalvej. My ancestors come from around there. We traced the name Gemal back to around 1600. In Danish Gemal means spouse/partner/wife/husband.

I tag:
- Asa Dotzler
- Christian Sejersen
- Allan Beaufour
- William Quiviger

Early adopter of Mozilla Firefox

Mon, 15 Dec 2008 22:10:53 +0100

(image) My son Mads is a early adopter of Mozilla Firefox.

The other day he got a Firefox tattoo on his left arm and was very proud of it. Showing it to everybody. And yes, it's washable.

So now whenever he sees a Mozilla Firefox logo he points to it. So when he sits next to my computer he has to point out all the time that he can see a Firefox logo.

Perhaps I can teach him to cry when he sees a Internet Explorer logo?

Mozilla Foundation non-profit no more?

Thu, 20 Nov 2008 09:01:44 +0100

According to Techcrunch Mozilla Foundation is being audited by the IRS and its non-profit status is in question:

On the audit of the Foundation there has not been any formal notification of issues. There has been inquiry regarding its tax exemption. Management believes that it is conducting its operations in accordance with its original application for exemption and for which it received the advance ruling as a public benefit corporation.

Read the full story

Mike Beltzner wrote to me saying that the article is full of inaccuracies.
The Mozilla Corporation is not registered as a non-profit entity, pays taxes, receives revenues, etc. The Mozilla Foundation is a non-profit organization, and its status is not under question. Google does not provide funds to Mozilla as "charity"; it's a negotiated revenue deal, and they make more money off of the traffic generated than they pay to Mozilla. It's easy to forget that, but this is not a charity issue; it's an "affinity" revenue sharing deal.
