Disable caching in Firefox

The following question is often raised when Firefox is no longer using the cache website for development: Why is it modified?CodeAfter refreshing the page, I still haven't seen any changes?
In fact, it may be that your Firefox does not download the updated file.
In this case, try clearing the cache by following the steps below:
At the same time, press Ctrl + Shift + Delete;
Select "cache ";
Press enter to confirm.
If you are developing your website all day, it is too troublesome to repeat the above steps. We recommend that you disable caching permanently as follows:
In the address bar, type "about: config ";
Find "network. http. Use-Cache ";
Double-click it until it changes to "false".

However, during Ajax developmentProgramCache is always used, so remember to disable caching or avoid using FF caching. So do not disable it permanently during debugging, because if you disable it, the user may not be disabled, so you can debug it, but the user does not.
