11. Click & Clean
Tidy up after yourself with Click & Clean, a browsing history eraser for Chrome or Firefox. Anything that the websites you've been visiting store locally (whether your login details or cached images) is deleted on demand.
12. Lazarus
As you may have gathered from the name, Lazarus brings your work back from the dead. If you're filling out a long form or document and your browser crashes, Lazarus can retrieve your data. Lazarus is available for Firefox and Chrome.
13. Disconnect
Almost every website out there is trying to track your activity and collect data on you. Disconnect (for Chrome and Firefox) shines some light on this murky practice, giving you more control and speeding up your browsing too.
14. InvisibleHand
Shopping online can be just as much of a chore as trailing down the high street, but InvisibleHand is here to help. It instantly compares prices across 600+ retailers, so you can always get the best price. For Firefox and Chrome.
15. DownThemAll
DownThemAll is the essential tool for downloading everything at once from a particular page on the web. This Firefox add-on will scoop up links, images and other types of content. You can pick and choose what to save, or get it all with one click.
16. The Great Suspender
If you're something of a tab hoarder you can quickly end up with dozens of websites open, and that slows your browser down. The Great Suspender extension can temporarily suspend tabs until you need them and free up memory space.
17. Chrome To Phone
Send links, pictures, text and just about anything else from your web browser to your Android phone with the Chrome To Phone extension. You'll need to install the Chrome To Phone app on your Android device as well.
18. Shareaholic
Shareaholic lets you instantly share anything you find on the web with your followers on Twitter, Facebook, Instagram, Tumblr and many other networks. The extension is available for all the major browsers.
19. Save To Google Drive
Many of you who use Chrome will also use Google's storage platform. The Save to Google Drive add-on lets you save text and images straight to Google Drive from your browser (you would never have guessed with a name like that). HTML pages can be saved as images or in a Google Drive format.
20. PanicButton
If the boss, your other half, your kids or your parents catch you looking at something you shouldn't be, PanicButton hides all of your open Chrome tabs in a flash. There is a Firefox equivalent available from a different developer.
