hi
i am sure you have heard of the problems in firefox 3 in relation to large cpu usage over time, especially when using javascript heavy applications.
we use your components (layouts,grids,toolbars,menus etc…) in firefox 3 and heavily use ajax.
we have noticed in firefox 3 it gets slower and slower the more our users use our software. they have to close their browser and restart every 20 mins
we know this is a firefox issue but have you guys ever seen this and do you recommend us to do anything to speed up the application
thanks

Are you using stable 3.0 or experimental 3.1 branch of FF? ( 3.1 branch uses different js engine, which still not finalized and may produce unwanted effects )
>>and do you recommend us to do anything to speed up the application
Normal AJAX loading must not cause problems for FF ( it has correct garbage collection logic, and removes unused XML objects from the memory )
The performance problem may be related to the architecture of app. If you are constantly creating new object without destroying old ones - similar effect can occurs ( most object has auto-destruction code attached to unload event )
Switching from new object creation to reusing of existing ones, can improve situation.
( if you app loads a lot of html content with images in dhtmlxwindows|dhtmlxaccordion - another known problem can occur , related to memory leaking, please contact us directly at support@dhtmlx.com if you need a hot-fix for it. )

we are using firefox 3.0 which is a problem for many which we found out by typing ‘firefox 3.0 slow’ into google
