Storage options

Browsers store different types of data about you and your preferences in separate containers. This includes, but is not limited to:

  • Cookies
  • Recently closed tabs
  • Local storage and indexedDB data
  • Browser history
  • Saved bookmarks
  • Extensions
  • Browser settings

Multilogin browser profiles' data is stored and synchronized in an encrypted form on the servers. Having various data containers enabled will ultimately increase the latency of browser profile loading and saving times. This is why only cookies and tabs synchronization are enabled by default. Other storage containers need to be enabled manually in the Storage options section.

To achieve optimal loading times, it is advised to only enable those storage options that are particularly useful to you.
Before closing Multilogin, make sure that the synchronization of all profiles is completed. Sync failure can result in loss of session data.

Local storage and IndexedDB

Although Local and IndexedDB storages are architecturally slightly different things, they are designed with one core goal in mind: to allow websites to store data about you locally. They work the same way as cookies do; however, local storage and IndexedDB are considered to be more secure and larger amounts of data can be stored, without affecting the website's performance.

Since websites have open access to these storages, they can be easily exploited for the purposes of user tracking by placing different bits of identifiable information about your activity in conjunction with cookies.

In Multilogin you have the option to enable Local storage and IndexedDB synchronization for your browser profiles.

It's recommended that Local Storage and IndexedDB is enabled to preserve the consistency of data that websites may place. If this option is left disabled, websites will see that such storages are empty upon each consecutive browser launch, which may indicate that they have been intentionally cleared out.
If you need to enable Service worker cache, Bookmark saving and Browser history saving, Local storage and IndexedDB must be enabled first.

Extension storage

Find the full instruction on how to add browser extensions and plugins here.

Extensions and their corresponding data are stored in a separate container from other types of browser data. Therefore, if you wish to use extensions and have them restored upon each browser profile launch, you will need to enable Extension storage.

Using extensions and plugins

In-app extension storage allows you to use browser extensions in the same way as in regular Chrome and Firefox:

  1. Create a browser profile with “Extension storage” functionality enabled
  2. Launch the profile and visit Chrome web store if you use Mimic or Firefox browser add-ons page if you use Stealthfox
  3. Choose your extension and click “Add to Chrome” or “Add to Firefox”
  4. Save the update using Multilogin extension and button “Close&Save”.
  5. Restart the profile to check whether the installed extension in the top right corner of the browser profile window
Some heavyweight extensions can lead to very slow browser saving and loading times, especially with slow internet speeds. In such cases, it's advised that extension pre-loading is used: a feature which can be found in the “Extensions” section of browser profile configuration view. This functionality is also useful for custom extensions.

If enabled, some plugins like Flash or Widevine may have security holes. Read the full explanation here.

Service worker cache

  • In Stealthfox profiles, the service worker cache is permanently enabled
  • In Mimic profiles, the cache is disabled by default, but there is a possibility to manually enable it
Keep in mind that when enabled, service worker cache significantly increases a profile's size, which can lead to slowness.

Browser bookmark and browser history saving

If you wish to have access to your browser profile browsing history or bookmarks next time the profile is loaded, you need to enable bookmarks and browser history saving. 

Password saving

If you wish to save passwords and other form fields in a browser, you need to enable password saving.

Additionally, after logging into accounts, we recommend selecting “Keep me logged in” and “Save password” in the pop-up windows.

Browser profile default settings

You can either change storage settings for a specific profile in its “Storage options” settings or set up the default settings for all the profiles you create in the “My account” “Preferences” section:
