So, Mozilla fires a lot of developers because of financial problems and this is how it decides to spend some of the remaining resources? Analyzing YouTube's usage statistics? Really?
Mozilla should realize a simple fact: if Firefox dies - Mozilla dies. Developing the FOSS privacy-oriented feature-rich browser should be the main and almost single priority for Mozilla. There are tons of things to improve in Firefox.
Just an example - integrating the Tree Style Tab extension natively into Firefox would be a killer feature.
Also the Mozilla VPN was a good idea. But where is it? Why is it still not available?
