Extjs is cool; but very slow on firefox !

January 5th, 2009

(sorry for my poor english)

I test ExtJS and it's very good... Grid and EditorGrid are very good tools. And on Internet Explorer 6 or 7 , it's rapid.

BUT on firefox (all versions), it's very slow ! Normal or it's a know problem ?

Thanks for your responses.

Ok thank you.

With firebug disabled and webdevelopper disabled on firefox.. it's rapid. Not too rapid than Internet Explorer but it's correct.

Thank you, ExtJS is very RooooOOoox !! ;)

Disable firebug and try again.

it only runs slowly if javascript.options.strict is on, as FF then makes the attempt at strict syntax checking (that's the overhead), not because some Extjs code generates strict warnings.

Dean Edwards has a couple of notes on FF here (http://dean.edwards.name/weblog/2007/08/firebug-slow/), you might want to review as well.

it's weird cause for me it's the opposite.

very fast on Firefox, medium speed on IE7 and laggy on IE6....

ext rock on FF :D/

Will this be fixed in ext.js 2.0 ?

When enabling javascript.options.strict (in about:config) in FF, firebug shows lots of warnings.
This is why pages are loading slowly.

I'm using ext.js 1.1.1 full.
