Can I recover a just lost post when using FireFox? Yes you can, but it’s a Hail Mary pass.
Have you ever written a long post on a web-forum, and as you submitted it the site reminded you that you’ve forgotten to add a subject, and when hitting the browser’s back button your post was gone?
I hate it when that happens.
Here is a long-shot that will probably be of use mainly to web-developers. I use a FireFox Add-on called Tamper Data
As I hit the page-forward button, FireFox asked me if I wanted to resend the data. Yay! That means it’s in the RAM-cache. Turned on Tamper Data, hit page forward and there was my post content!
All I had to do was to copy the contents to a text editor, clear it up again, and voila! I had saved my post.
Note: this will only work if you have had Tamper Data already installed. If you have to quit FireFox to install it, the post will be cleared from the RAM when you quit.
Sometimes a Hail-Mary pass works :)
