6. Clear Cache

This extension is a souped up version of what’s already available in Chrome. While you can go through Chrome’s Clear Browsing Data option, this extension gives you a great deal more options on exactly what you want to be cleared, and it will save your preferences.

For instance, if you just want cookies from a particular domain cleared, you can have the extension handle this for you. Additionally, you can clear out things like your local storage data and plugin data as WebSQL data, which is very helpful since you can’t automatically or easily clear WebSQL data through Chrome.

7. Window Resizer

For web developers and app developers, knowing what your application looks like on various screen sizes is essential. Even if you’re designing a website or app to be adaptive or responsive, you still need to verify that the site or app will work on a variety of screens. While you could test a site on several devices, the easiest way to verify that things will fit properly is to use Window Resizer.

Using this extension, you can either pick from a number of preprogrammed and common screen sizes or put in manual width and height settings. The only downside is that the scrollbars on Chrome won’t always mimic what you see on a different device, but you can still verify that elements will show up properly.

8. One Tab

OneTab is arguably one of the best Chrome extensions for users of any type. If you’re like many people, you end up with a lot of Chrome tabs open. This not only can make it difficult to go back to the tab you currently need, having a bunch of tabs open can also start eating away at your computer’s resources at Chrome starts using increasing amounts of memory.

This extension allows you to keep track of the tabs you’re using and have visited without needing to keep them open or worrying about bookmarking them and coming back. As soon as you start to notice that you have too many tabs open, you can just click on the OneTab icon and have your tabs converted to a list. Using this extension also allows you to walk away from your computer without having to worry about Chrome crashing and taking all your tabs with it.

9. Check My Links

Having a page full of broken links can be frustrating for visitors and frequent users alike. Using Check My Links, you can find out within a few seconds if there are any broken links on a page. The extension allows you to ensure that it’s not looking at a cached version of a page, and it lets you use either HEAD or GET to check links.

While this is a pretty basic extension, it’s a great Chrome extension for developers because it also allows you to put in a list of domains that you don’t want to be checked. For instance, if you want to exclude ad networks from the domains that the tool checks, you can do that. You can also use the tool to verify both internal and external links, and you have the option to check or not check nofollow links.
