I mainly test scripts on Opera (currently version 26, the same engine as Chrome). But it was worth trying Firefox, found 2 things: the principle of addressing variables is different (if this variable is visible in Opera, then there are some in Firefox that are either initialized late or not announced at all) and frantically eats RAM, which is not observed even in Chrome . Also, there are errors in the webgl logs that are not detected in the Opera.

Firefox 34.0.5
Windows 8.1 x64

  • And what is the question? ru.stackoverflow.com/help/how-to-ask - Nickolay
  • Emm .. from the context it was difficult to understand that the question would be "Why is this seen in Firefox?" - Ni55aN
  • My link says, in particular, "Be precise: If you ask a fuzzy question, you can get the same fuzzy answer." In your case, the fuzzy answer is obvious: either there is an error in your code, or in Firefox, or there is no error, but there are different technological solutions adopted in the Opera engine compared to the Firefox engine. To get a more useful answer, ask a more specific question. - Nickolay

    @Nickolay, the text on the link appeared much later than the question was asked. - Nofate ♦
