Browser performance issues caused by Flash?

I’ve been having issues in the last weeks where my CPU would peg at 100%. This is typically caused by a web page with an embedded Flash object (e.g. an ad or a music player). Closing the respective tab brings the CPU back to normal. This happens to me on Firefox 2, IE6, Safari 3.1 and SeaMonkey 1.1.9.

I’m running Flash 9,0,115,0. I will try upgrading to the latest version and see if this improves anything.

It’s not the first time that I see a third party component hurting performance and stability of the browser. I wonder how many extension the Mashable guys are running and how those impact the stability of Firefox. Disable/remove all extensions for a few days and see if the browser still crashes as often.

Let’s Get Rid of WWW.

While I was watching a friend typing a URL into a browser I realized that I never type the ‘www.’. Everyone has stopped typing ‘http://’ a long time ago (hopefully – stop now if you haven’t and start saving time). But I would guess that the majority is not omitting ‘www.’ yet. Now strangely enough since I realized this I keep getting stuck on sites that require the www!

So please always add a CNAME entry without the ‘www.’ to your full A name. Make is easy for your users to reach you. Thanks for making my life easier!

I guess I’m using the address bar as command line to a certain extent (F6 is my best friend). What are the search engines going to do when people stop using them for navigation?

Note: This is a DNS configuration only. No need to set up any redirects. And a client-side redirect is definitely not the right thing to do! Right comScore? Although I appreciate not getting a 404.

Firefox 2.0 rc 3

Firefox just upgraded itself to v2.0rc3 (from rc2). There are two really cool changes coming with version 2.0 of Firefox:

  • Spell check as you type in textarea
  • In page search in textarea

As we spend more and more time in the browser, small improvements like the two above make a huge difference. I spend more time in twiki and web-based email than in any desktop application.

Thanks Firefox!

Ajax = No Installation

About every article about Ajax starts with some mediocre explanation of what Ajax stands for and the author’s best guess on what it actually means. A common misconception is that the technology is new. The term is new however and is causing long debates what it should or shouldn’t be used for.

The acronym Ajax has long lost its technical meaning and is being used to describe the interaction model rather than the underlying technologies. Which got me thinking… In my world Ajax means:

Enhanced website providing an application like user experience

Which implies:

  • Accessed using a web browser (IE and FF a must, other browsers a plus)
  • No software installation, no explicit download
  • Allows for more interesting user interaction than just clicking on links (think drag-n-drop, keyboard shortcuts)
  • No page-to-page transitions

The use of Ajax in the name of the following two products is debatable using the above interpretation:


[via Ajaxian] requires you to download and install a WinAMP plugin. Note that this seems to be required for the server side only though. You can then access the interface remotely from a browser (IE and FF).


[via Ajaxian] uses XUL and therefore requires Firefox. Very impressive though!
