There are two files aware.js and aware_full.js. The first one represents the compressed version of the other one. At runtime only one file is used - usually the compressed one. However, FF under MAC for some reason cannot handle the compressed version. The workaround, therefore, is to use the second file - the full version.
To use this file you need to rename it to aware.js because Aware IM looks for this name.
So this is all good. Now, if you rename the web application folder you need to MODIFY THE CURRENT file to rename "AwareIM" prefix in this file with your folder name. Normally you do it in the compressed version. If, however, you replace the compressed version with the full version, you need to perform the same change in the full version as well - i.e. not only rename the full version to aware.js, but open it for editing, search for "AwareIM" and replace it with the name of the folder. If you don't do this and just rename the file, your login under FF on Mac will work, but you will not see any data.
