Note: CacheViewer is a front-end app for easily accessing and searching the memory cache.

Before

Viewing the cache in Firefox using “about:cache” provides some information about the contents but may not be the most efficient method available for some people.

CacheViewer in Action

Once you have installed the extension there are three easy ways to access your new cache viewer. The first is using the “CacheViewer Command” available in the “Tools Menu” and the second is using the keyboard shortcut “Ctrl + Shift + C”.

The third way is by adding a “Toolbar Button” to your browser’s UI. All three work equally well…choose the method that best suits your personal needs.

When you access the “CacheViewer Window” this is what it will look like. You may decide to resize it and move (or hide) some of the columns for the best viewing. You can easily scroll through the cache contents and preview images if desired as shown here.

If you keep the “CacheViewer Window” open you can refresh it as you browse using the “Refresh Button” in the lower right corner. This is a nice, quick, and very simple way to access the cache on demand and save items to your hard-drive if desired.

Note: The “CacheViewer” can also be set to open in a new tab instead (see “Options”).

Options

Choose whether “CacheViewer” opens in a separate window (default) or in a new tab.

Conclusion

If you want a quick and simple way to view the cache in Firefox then the CacheViewer extension is just what you have been looking for.
