Решили отменить полоски прогресса на вкладках и под url-строкой из-за причин:
- (design) different location for background and foreground tabs
- (design) hard to notice / too small
- (design) removed important feedback about connection state
- (implementation) no way to truthfully relay overall progress
- (implementation) lack of immediate feedback
- (implementation) wrong color
- (implementation) 30% CPU performance hit
