TabContainer Firefox problem

I am using tabContainer for tabed navigation with update panels inside tabpanel for async updates to the server.

Ome tab panel contains FCKEditor. I have experinced 2 errors on the page when using Firefox:

1. The page is loading very slowly and the following message is displayed in the status bar:
"Transfering data from localhost"

2. FCKEditor when used inside tab panel and updatepanel will losse the text entered when I try to update asinc to the server.

I have tried the following solution but it did not work:

The most relevant error in Error console seems to be the following:
Warning: Error in parsing value for property 'display'. Declaration dropped.

Line: 5

With the following data:

/* default layout */.ajax__tab_default .ajax__tab_header {white-space:nowrap;}.ajax__tab_default .ajax__tab_outer {display:-moz-inline-box;display:inline-block}.ajax__tab_default .ajax__tab_inner {display:-moz-inline-box;display:inline-block}.ajax__tab_default .ajax__tab_tab {margin-right:4px;overflow:hidden;text-align:center;cursor:pointer;display:-moz-inline-box;display:inline-block}

There is also a bunch of css errors.

Needless to say everything works perfectly in IE 7.

Any help/suggestions will be greatly appreciated.

P.S. To isolate the problem - I have taken fckeditor out of the page and everything works fine. Then I added FCK Editor outside of update panel and tabcontainer and the problem reappeared, hence it is safe to conclude that the problem is related to FCKEditor.

Solved the problem.

FCKEditor subfolder containing all the setting,images etc for FCK Editor MUST be placed in the root folder of a web application. Probably there is a way to do it but it is not an issue any more.
