performance is sluggish on Firefox #24

Closed pixelzoom closed 10 years ago

pixelzoom commented 10 years ago

This issue coalesces several other issues, all of which dealt with substandard performance on Firefox. The issues were for various platforms, so this appears to be a cross-platform issue. The original issues (all closed as "wontfix") were: #23, #18, #11, #8.

There is some optimism that the upcoming Firefox 25 release will address performance.

Rather than add code like 'if (firefox) { use canvas }' throughout the sim code, we decided that this should be handled by scenery. Created this scenery issue: https://github.com/phetsims/scenery/issues/161

Closing this ticket.
