I see. It's something else's fault. Mozilla Firefox had more market share than the declining IE and the opportunity to get further ahead at one point and it still lost. Even the CEO was confident in competing against Google if they were to release their own browser at the time and believed that they would not be >80% dependent on the companies revenue. [0]
The inability to recognise responsibility of past failures is perhaps the reason why Firefox has failed and the parent Mozilla is still totally reliant on Google's money.
