#4 Lazarus

Everyone must have been through the experience of having to fill out a form again because it timed out the first time or simple because your browser crashed. This handy extension will ensure that doesn’t happen again. Lazarus saves everything you type so anytime the worst happens it can be recovered at ease by clicking on a menu item. The data is encrypted and is saved on your computer locally, so it is safe. Lazarus is another must-have Form Recovery add-on.

#5 HTTPS Everywhere

Created by the Electronic Frontier Foundation and Tor project, this important security enhancing add-on encrypts your communications and protects your identity when accessing unsecure websites. Not every website offers HTTPS support and even those that do can be difficult to use and might not be completely secure. HTTPS Everywhere fixes that by automatically switching over from the unsecure HTTP connection to the secure HTTPS connection on the fly whenever needed. It protects the users from many forms of surveillance and account hijacking.
