How to view/delete local storage in Firefox? [closed]

问题

In Google Chrome there is an easy way to see what's in local storage as well as modify or delete it after inspecting it.

Is there a tool or something to do the same in Firefox?

回答1:

You can delete localStorage items one by one using Firebug (a useful web development extension) or Firefox's developer console.

Firebug Method

1. Open Firebug (click on the tiny bug icon in the lower right)
2. Go to the DOM tab
3. Scroll down to and expand localStorage
4. Right-click the item you wish to delete and press Delete Property

Developer Console Method

You can enter these commands into the console:

localStorage; // click arrow to view object's properties
localStorage.removeItem("foo"); 
localStorage.clear(); // remove all of localStorage's properties

Storage Inspector Method

Firefox now has a built in storage inspector, which you may need to manually enable. See rahilwazir's answer below.

From Firefox 34 onwards you now have an option for Storage Inspector, which you can enable it from developer tools settings

Once there, you can enable the Storage options under Default Firefox Developer tools

To inspect your localStorage items you may type console.log(localStorage); in your javascript console (firebug for example or in new FF versions the shipped js console).

You can use this line of Code to get rid of the browsers localStorage contents. Just execute it in your javascript console:

localStorage.clear();

As 'localStorage' is just another object, you can: create, view, and edit it in the 'Console'. Simply enter 'localStorage' as a command and press enter, it'll display a string containing the key-value pairs of localStorage (Tip: Click on that string for formatted output, i.e. to display each key-value pair in each line).

There is now a great plugin for Firebug that clones this nice feature in chrome. Check out:

https://addons.mozilla.org/en-US/firefox/addon/firestorage-plus/

It's developed by Nick Belhomme and updated regularly

I could not use localStorage directly in the Firefox (v27) console. I got the error:

[Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: debugger eval code :: :: line 1" data: no]

What worked was:

window.content.localStorage

Hope this helps.

Try this, it works for me:

var storage = null;
setLocalStorage();

function setLocalStorage() {
    storage = (localStorage ? localStorage : (window.content.localStorage ? window.content.localStorage : null));

    try {
        storage.setItem('test_key', 'test_value');//verify if posible saving in the current storage
    }
    catch (e) {
        if (e.name == "NS_ERROR_FILE_CORRUPTED") {
            storage = sessionStorage ? sessionStorage : null;//set the new storage if fails
        }
    }
}
