WordPress Bug with Windows Firefox
I found a bug that only seems to appear when you use the Windows version of Firefox 2.0 with WordPress 2.1. When you write a post using the visual editor, several buttons don’t appear on the button bar. These are the buttons from Strikethrough to Insert/edit image.
The strange thing is that when I use Firefox 2.0 in Fedora 6, the entire button bar is there. The bar is also complete in Internet Explorer 7.
I mainly use Firefox for web browsing but it looks like I’ll be using IE 7 to compose messages until the Firefox bug is fixed. For a while I was using the Code tab to insert hyperlinks and format my posts, but I’m too spoiled to stop using the visual editor and manually code messages.

however, after several hours, everything went to normal.

I still have the problem with the button bar in Firefox on Windows. I’ll have to take a look at the PHP code and see what’s going on there.

The button bar is displaying properly now in Windows Firefox. I don’t know why its working now. I didn’t make any changes to the PHP code.
