Hello, there seems to be a gentoo-only issue with the 'loading image' that appears while loading a webpage (this does not happen on other distros - something to do with how we emerge the sources?). As I'm unable to show this with a screenshot - I'm attaching a short video recording. I've marked this as 'confirmed' because it happens for other people as well (confirmed by Daniel "lejonet" Kuehn).
Seems it's not possible to upload >1MB files as attachments here. The video recording is available through: http://flz.politeia.in/gentoo/firefox-loading-issue.ogv
Confirming. Though I have tried 17.0.5, same thing. Ivan.
