Quote from: Bruno17 at Mar 24, 2015, 08:49 AMhave the same issue with FF and the MODX-manager since some weeks.
Deactivating firebug for manager-pages seems to fix the timeouts for me.
Yeah but enabled Firebug on manager page is one problem
(1), and FF freezes without "Unresponsive Script" popup is completely different thing
(2).
So if you have enabled Firebug AND AdBlock enabled AND "compress_js" enabled, you have really big "freeze COMBO"!
For all who have the same problem:
1. Disable "compress_js" setting on MODx, clear cache (all folder core/cache - if you can),
(should help a little for (2) and improve performance for (1))
2. Disable AdBlock for all domain and not only on current page
("Don't run on pages on this domain" option), (should help for (2))
3. Disable Firebug on current domain (or whole addon for test)
(should help for (1))
and 4. let us know in this thread if it's helped
P.S.: You can try run firefox in
Safe Mode without addons (
