>Firefox 188.8.131.52 was released. No features added, just some security vulnerabilities fixed.
To enable support for color spaces in Firefox 3 beta 4, do the following:
- Go to about:config
- Confirm you want to edit settings
- Set the option “gfx.color_management.enabled” to “true”
- Restart Firefox
Now check out some sites. Like with Safari 3, colors in sites may look quite different, since an extra step is applied to convert the colors from the original color space to the color space for your screen.
For web developers this smart behavior introduces some challenges, since sites now look different on different browsers on the same platform. Of note, Safari and Firefox implement color space support differently: Safari only adjusts images (such as PNGs), while Firefox also adjusts CSS colors.
So even between Safari and Firefox 3 with color space support enabled, there are differences, as reported in Firefox bug report #424356 (see the attached screenshot) Firefox seems to do a better job here than Safari, because with the latter the colors of different elements on a web page may mismatch, as can be seen (with Safari 3.1) on a website like http://www.route65.eu/.
For web developers, here’s a pragmatic approach:
- make sure your images do not include a color profile (saves ~4KB)
- do not specify colors in CSS if there is an image that needs to match the color, instead use a dot image with the exact same color
Still your site will look different on browsers with or without color space support, but at least you work around the problem in Safari 3.1.
Yahoo! have built on Firebug to produce a tool that goes even further. They call it: YSlow for Firebug.
Based on “Thirteen Simple Rules for Speeding Up Your Web Site” YSlow analyzes a web page, produces some reports (with a score card) and gives advice on improvements. This can be a great help in improving your website’s performance and reduce it’s bandwidth usage.

>Although I’m not too enthusiastic about the new Apple Safari 3 beta, one simple feature I do appreciate a lot is the way it highlights find-on-page results. It really makes day-to-day browsing more productive.
I wonder if there is any Firefox 2.0 plugin that can do something similar. So far I haven’t been able to find anything.
>For a customer I bought an iMac 20-inch (2.16 GHz C2D, 2GB), which I’m now configuring. On top of Mac OS X 10.4.9, iLife and iWork ’06 I’m customizing the machine as follows, to suit his needs:
- Parallels 3.0 and inside it Windows XP Home Edition.
- NeoOffice 2.1, with the Dutch localization pack, setting the default file format for saving to the Microsoft Office (2000) file formats.
- Adobe Reader 8.1 for viewing PDF files.
- RealPlayer 10 for viewing Real content.
- Flip4Mac WMV 2.1.2 for playing Windows Media in QuickTime.
- Microsoft Office 2007 (within the Windows XP virtual machine) as a fallback for NeoOffice and in order to be able to open/convert Office 2007 files (such as .docx and .xlsx).
- Witch (for Option-Tab) as an improvement over Cmd-Tab.
- Firefox 2.0 (as a replacement for Safari) in combination with the del.ico.us Bookmarks extension, enabling the option Hide Bookmarks Menu and the FasterFox extension.
- PageSender 4.0 ($39) for sending and receiving faxes.
- Adobe Flash 9 for playing Flash content in all browsers (Safari and Firefox).
- VueScan 8.4 to support the HP ScanJet 5470c scanner.
Some challenges I’m still facing:
- Which version of Office 2007 should I choose? I expect only Word or Excel is occasionally needed.
- How do I convert all current faxes from WinFax Pro 9 to the Mac?
- How can I use VNC through the DSL modem and firewall? — Update: this is fairly easy with an SSH tunnel.
- (How well) does VueScan integrate with PageSender? Or how well can I make them integrate using Automator?
>If you read previous of my posts, you must have concluded I seem to enjoy listing (minor) issues I find in applications. Somehow I indeed do. I’d like to report these issues to their creators, but then this typically costs a lot of time and effort. Just listing stuff on your blog is easier and then you can still use that information later to submit some issues later on.
Here’s some feedback on QuickTime issues:
- When I right-click in a QuickTime area on a web page, then I get a number of options in a context menu. However, if I want to choose none of the options, there’s no way to get rid of the context menu. It seems I have to click one option. Even worse, even if I move to a different tab, the context menu does not go away and still shows up on the other tabs.
- When a QuickTime movie is not completely loaded (yet) but still starts playing and then gets to the end of the already loaded content, it restarts at the beginning of the clip. That’s plain annoying.
- When the loading of a movie does not seem to progress, for example after the internet connection has been disrupted, there’s no abvious way to see whether it is still loading and no obvious way to make it continue the loading without restarting.
- With a paused QuickTime movie on a web page, scrolling makes the movie appear and disappear, showing the background behind the movie instead of the movie itself.
- A movie cannot be saved until it is fully loaded.
- The plugin context menu has two similar items: Save as source and Save as QuickTime-movie. Both save as a file with the .mov extension. The difference is not obvious at first glance.
This is QuickTime (Pro) 7.1.3 with the QuickTime Plug-in 7.1.3 on Firefox 2.0.
- It requires a forced stop on a regular basis (like once a day).
- When searching (Cmd-F), the back key combo (Cmd-LeftArrow) does not work anymore.
- When editing a text field in Blogger Beta, switching to a different tab keeps the blinking cursor visible.
Still I prefer using Firefox over Safari. One of the reasons is that in Safari, the Blogger Beta post edit screen does not properly show the icons (bold, italic, etc.) properly.
