FEBE hangs, "Unresponsive script", "Script is busy" warning

[cbaker_admin]

If you are using FEBE 6.x or greater and Firefox 3.6 or greater and FEBE "hangs" and does not complete a backup within a minute or two, follow the steps outlined here:

In about:config there is a preference called dom.max_chrome_script_run_time that controls how long Fx waits before giving the "Script is busy" message. The default value is 20 seconds. Try changing it to "60" to see if that will eliminate the problem.

How to: Type about:config in the Firefox address bar. If you get a box that warns you about being careful, accept it to continue. Type (or paste) dom.max_chrome_script_run_time in the filter box. Double click the preference and change the value from 20 (usually) to 60. Close the tab. Perform a backup.

If you still get the "Unresponsive script" warning, try this:

Set the dom.max_chrome_script_run_time to 0 (zero). This essentially turns off the time limit. Perform a backup and time the number of seconds it takes. (If it takes more than five minutes or if the progress bar in the FEBE progress window starts moving again, abort the backup -- It's not working.) Set the dom.max_chrome_script_run_time to the number of seconds the backup took plus 10. For example, if the backup took 90 seconds, enter 100.[/quote]

Fx 3.6 is supposed to be much faster than 3.5.7, but maybe some things (like nsIZipWriter - the XPCOM component FEBE uses) are actually taking longer than before.
