Dont know if it could give a good way to solve your problem,
but with chrome,
i used a plugin for cache :
https://chrome.google.com/webstore/detail/clean-guru-cache-history/njjijbcogjkninkeeobbbkcbiblpjafa
Very usefull when i developped on a new theme.
Other idea :
Check here :
/modules/system/admin.php?fct=preferences&op=show&confcat_id=1#theme_fromfile
"Check templates for modifications?" should be "Yes" for dev.
