Can't discard and refresh favicons
Some sites (twitter.com for example) have wrong favicons on my tabs, so I want to discard and refresh favicons.
Normally, this can be done by removing "favicons.sqlite" from profile folder. However, it doesn't work with Tree Tabs.
Strangely, now twitter.com has correct favicon on Horizontal tabs and wrong favicon on vertical tabs.
