I am staring to write again after a long time to log my technical experience gained during the development of fewbs
I will discuss about firefox issue of flash rendering today. I am using Firefox 3.5.7 with Flash 10.
Problem: Flash based widgets were not rendering on the tabs i.e. I could hear the sound from them but they were not rendering.
Solution on web:
1) Doctype issues as given on experts-exchange
2) An old bug of firefox 3 and Flash 9 which I thought was not relevant. Adobe notes
RCA: When switch of tab is made in fewbs(not in firefox) the last tab's display was set to none and the current's one to block. As a result the contents of flash movie in the hidden tab rolled back to beginning and movie stops playing. When
the user goes to the last tab, firefox loads the whole movie again. To fix this, I used zIndexes to place the frame over each other and fool firefox that the the tab is still active.
Due to this, firefox intermittently stopped rendering flash movies even in the current tab as apps. It was frightening at first as I thought I might have hit a firefox bug. Excluding youtube from embeddable apps section seemed like a death stone.
Soltuion: After hours of digging, I, thankfully, noticed the above happening. Now I no longer use zIndexes. I quietly transport the tabs to a style top value of -1000px :)
