PLEASE make it toggleable to close all tabs on the "Forget X Minutes" button on Mozilla Firefox

[n1zle]

I recently lost 150+ tabs on Mozilla Firefox because I wanted to remove my last 5 minutes of browsing from my history. I have NO IDEA why the tabs I opened 3 months ago would be closed by this, and not be under "Recently Closed Tabs". Or why there's no backup file from 5 minutes ago I can restore from, even if it means creating a files when I "forget 5 minutes", then delete the file after a day or something. It would cost nothing in space and processing power, and would prevent such accidents.

Currently, I rate the Forget Button "Useless/10".

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Of course this would be abandoned, since the community has developed their own ways to fix this mess. Such as backing up the cache folder every few hours/days, would have prevented this accident, caused by a simple, yet badly designed,  "feature".
