A.D.D. In IT

Its been a while since I posted, but I wanted to share a setting that really shouldn't be enabled by default in Firefox.

I had been following various threads on Firefox memory usage, and after installing Firefox 10 I noticed Firefox started with something like 200 MB of RAM but quickly ballooned to some 500 MB after a few tabs open.

After some research, I tried out a setting in the about:config page, and it literally halved my RAM usage, especially with large numbers of tabs.

This is the image.mem.decodeondraw setting in Firefox.

Kenny and I ran into an interesting debacle yesterday while attempting to fix a bug. This debacle dealt with the use of XML namespaces and XSL transforms. Even though both of us are proficient with XSL, we still found ourselves in a 2 hour bug fix over what eventually turned out to be a simple namespacing problem.

The rule is... if an XML document has a default namespace it must be matched in XSL by prefixing.
