I'm running Firefox 26 on OpenSUSE 13.1 64bits. I got problem in Firefox 26 to use IBM Lotus iNotes and the recommandation is to revert to Firefox 24 ESR. I tried to do this, but it didn't work. Now i uninstall all Firefox and installed the latest version (26) again. Now Firefox won't load any web-page. It just saying "Connecting..." but nothing happens. No timeout nor error-mesg. If i run Firefox in terminal, i get this message; (process:3072): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed --------- I also backed up the profile og recreated a new profil. I suspect that the version 24.2 ESR did some change to files, but i uninstalled everything, rebooted and installed new. Still it doesn't work :-( What is wrong!?
