Firefox is 72 now. How can you have so old version?

Truth, it works 100% of time, except for GL UI. But there is a reason about the testing system I am using to use pre-Quantum for certain applications.

But really it is not very old. I think 3 years? I have family with browsers much older. How many people are still only using Windows XP? (I don’t know but I think it is probably too many people)

Seems firefox force you to upgrade

No this is not true. It is an option.
