In a lot of cases I have to to double the work because I usually forget that the displayed results are being processed from the cached files not the actually server results.
Anyhow, this is how to disable caching in firefox
Open FireFox -> In address bar type:
In the search bar that will appear type:
Right click on the results of the search and click “Toggle” making sure its set to false
Now all your pages will not be processed from the cached files and will be actual server response results
