Earlier on I had Facebook up using Firefox, when the cursar changed to the "roller" thing in the middle of the mouse, and the whole screen could be made big or small! I rolled it so facebook was really small on the page- but now it is stuck like that! Even after restarting the computer! Any idea what happened? Only facebook does this- other websites look normal on the same firefox. Thanks
Firefox has this great feature to make reading sites with small text easier (especially if you have bad eyes). It remembers the setting individually for each site.
It's part of firefox itself since version 3; for version 2 there was a plugin that did the same.
Hold control (ctrl), and press the plus and minus buttons on your keyboard to produce the same effect.
To reset to the website's original size, press ctrl+0 (zero).
