Being the nut job that I am, I can't seem to cut back on the amount of tabs I keep open in Firefox — which usually total anywhere from 50 - 100. I know, I'm killing my RAM in the process and my MacBook is secretly threatening to crash on me once and for all. I used to be a big fan of CopyAllURLs, a handy Firefox add-on that would copy all of my open tabs and I could paste them in a text file. Therefore if Firefox ever crashed, and it didn't restore properly, I had all my fabulous tabs saved for future reference.
So you can understand how upset I was when I downloaded Firefox 3 and realized that CopyAllURLs wasn't compatible with the latest version of Firefox. Thankfully I found an even better add-on — Send Tab URLs. Send Tab URLs will not only create a list of all of the tabs from your browser, but it will send you an email with them as well (up to 24 tabs max)!
