These dots can be easily seen on any transparent/black toolbar.

Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:8.0a1) Gecko/20110807 Firefox/8.0a1 I could not reproduce the issue.

What progress bar are referring to? Could you give the steps to reproduce the issue and also the firefox build you've experienced it? Thanks!

I'm using only Nightly, but IIRC this bug is valid for all the Fx branches. And actually this happens everywhere a native progressbar is used: if you use Status-4-evar extension - then take a look at the progressbar of pages' load process. if you don't - find any progressbar in the Fx and change the background color for it to black, so these dots can be easily seen. A good example is progressbar in downloads manager: 1. start downloading any file 2. open downloads manager 3. pause the download 4. click on the active download, so it's background gets changed from white to blue 5. take a look at the white dots in the corners of progressbar: http://img89.imageshack.us/img89/7962/70445757.png And any add-on, that uses built-in into Firefox progressbar - they all inherit this bug.

Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:8.0a1) Gecko/20110807 Firefox/8.0a1 I could reproduce this issue. I've also tested it in WindowsXP, Windows 7 x86 and x86_x64. *Note:it reproduces since Firefox 3.6.16 Setting resolution to NEW. Thanks!
