Webplayer saves file instead of playing it

In order to play videos (Flash Format) on the website I use JW Player on my pages. But I seem to have some problems with it.

On certain Firefox browsers when clicking on the player it chooses to download the file instead of playing it in the browser. On the same computer I tried it on Internet Explorer and there my webplayer is showing badly, it stands in the top left corner (whereas it should be in the middle of the page) and flickers a 开发者_StackOverflow中文版bit.

Because everything is in development the webpage is only available through our servers. In other words, I can't provide you any link with details.

So my question is, why do some browsers download the video instead of playing it? And is there a possible free alternative to JW Player to play flash videos?

Any comment will be appreciated. Kind regards, Floris Devriendt

I prefrer flowPlayer to jwplayer but nevertheless, jwplayer is also a solid player and you should not have this kind of problems with it.

Perhaps your web server do not serve the flv/mp4 files (you do try to play those files I hope) with the correct MIME type, which results in the player not recognizing the files as files it should play.

Instaling the latest version of Adobe Flash helped solving my problem.
