Yes, through an entry in file user.js. > Anyway, with no caching I encounter a website who is too slow now. > So It's better to not disable the cache.... > > What about: > "Compare the page in the cache to the page on the network" set to: > "Every time I view the page" When an HTML file is generated or modified "on the fly", its time-stamp is set to when that happens. With "Compare the page in the cache to the page on the network" set to "Every time I view the page", the time-stamp of the file on the Web server has to be fetched for comparison with the time-stamp on the cached file. Thus, if a Web server is slow, the comparison will be slow. If the comparison fails, rendering the Web page will be slower than if caching were disabled because you must add the fetching of the server's time-stamp to the downloading of the HTML file. At one time, security implemented in Mozilla-based browsers meant that Web pages downloaded as HTTPS were never cached. I do not know if this is still true. However, more and more Web sites now use HTTPS instead of HTTP. If not caching HTTPS sites is indeed still true, it further reduces any benefits from caching beyond the reduction from "on the fly" generation or modification of Web pages. My broadband connection gives me more than 75 Mbps downloads. I chose to disable caching because fewer and fewer Web sites benefit. -- David E.
