This one-hit wonder of a Firefox extensions nevertheless provides a useful feature for those who do a lot of cutting and pasting from Web pages into text fields or documents. AutoCopy copies any text you highlight to the clipboard--it's that simple.
It does do a bit more than that, though. The extension's Options menu lets users configure highlight behavior, post-copy pasting behavior, keyboard shortcuts, toggling a Status Bar button, and a menu that pops up after copying. From that pop-up menu, you can automatically paste the selected text into the location bar, the search bar, a new tab, access previous clipboards, or undo the copy.
AutoCopy's only flaw is that sometimes after installing it, Firefox doesn't always realize it should be in the active extensions list. Research on the AutoCopy Web site revealed no answers, leading us to conclude that the add-on might conflict with other add-ons. To remedy this, we recommend trying to install it again. Once installed, though, AutoCopy worked flawlessly and was immensely helpful in speeding up tedious copy-and-paste jobs.
