I was reminded recently that I am human. I made a mistake and when I make a mistake it tends to be a big one. Now I am pretty paranoid about backing up data so when I discovered what I did I knew I would be able to restore pretty much everything from the backup I had, but there was a few pages of new content that I did not have a backup for.
As I started fixing my error I kept wondering how I was going to restore that new information that the client had placed on their website between the last backup and my screw up. Then it dawned on me, I had read the pages that the client added to the site on both Firefox on my desktop and Firefox on my laptop. A quick about:cache?device=disk and sure enough they information was cached. The only problem is that Firefox does not give you a very user friendly view of the cached files. I needed an easy way to save the information so I could add it back into the website.
This is where I discovered the Firefox CacheViewer Addon. It allows you to sort the items in the Firefox cache by key, size, type and date. Using the Firefox CacheViewer I was quickly able to find the couple items I needed, save them as HTML files and copy the information out that I was missing.
If you every need to go looking though your Firefox cache for some information that you might have lost, or just want to browse the cache and see what Firefox has saved take a look at the Firefox CacheViewer Addon. It sure helped me when I made my mistake.
