Usually slow speed means that something is interfering with the synchronization of the application with the servers or blocking the connection to the app. This article describes several solutions to this issue.

Check your system

Make sure that your computer meets our minimum system requirements.

Test your Internet connection

  1. Close the Multilogin application
  2. Connect to a different network (for example, use mobile internet)
  3. Restart the app and launch browser profiles again

Disable 3rd party apps

Antivirus, VPN client, Proxifier, Firewall installed on your computer may block communication ports between the application and the server. Antivirus, VPN client, Proxifier, Firewall can be disabled. You may also be able to whitelist Multilogin with your antivirus software.

Test your proxy

In most cases, you need to check if this problem is proxy-related by trying to connect to your proxy through a regular browser. You can use a browser extension to test proxies in Firefox and Chrome. You can also refer to these pages for instructions on how to test a proxy on Windows and Mac.

If the connection is slow in a normal browser with your proxy, reach out to your proxy provider for further assistance.

Edit your file

Navigate to the \ folder, which is located in the user directory

  • Windows: C:\Users\%username%\
  • Mac OS: /Users/%username%/
  • Linux: /home/%username%/
To find this folder on Mac, open Finder and press Cmd + Shift + H to open a user folder, then press Cmd + Shift + . (period) to show hidden files. After that, go to the folder.
  1. Find the file there and open it with any text editor (for example, Notepad)
  1. Add the following line to your file: multiloginapp.connection_eu = true
  1. Save and close file, restart Multilogin

Reinstall the app

These actions will log you out – make sure that you remember your Multilogin password.
This will not cause any data loss; all your profiles and session data will be saved.


  1. Close Multilogin
  2. Go the C:\Users\%username%\ directory
  3. Delete the folder
  4. Launch Multilogin and wait until browser components are redownloaded and the green progress bar at the top disappears

Alternatively you can go to “My account” in the Multilogin app and click “Open logs directory”, then close Multilogin. In the window that opens, go two folders up into your user folder. Afterwards proceed from step 3.


  1. Go to “My Account” - “Open logs directory”. Close Multilogin
  2. In the window that opens, go two folders up and enter your user folder (depending on the view style of the Finder, you need to either choose that folder in the left column of the Finder or right-click on the name of the Log folder)
  3. Delete the folder
  4. Launch Multilogin and wait until browser components are redownloaded and the green progress bar at the top disappears

Alternatively you can open Finder and use shortcuts:

  1. Press Cmd + Shift + H on the keyboard to open a user folder
  2. Press Cmd + Shift + . (period) to show hidden files and proceed from step 3 above

Disable Service worker cache

If enabled, this setting can increase the profile size and loading speed. Its default setting is "Disabled". We only recommend enabling it if the target website requires Service Worker to function properly.

  1. Go to your profile settings and select "Advanced" → "Storage options".
  2. Disable the "service worker cache" setting and click "Update profile"
  3. Start and close the profile, wait for the synchronization to complete. The next profile start should be faster than before

Send us logs and proxy details

If the issue with slowness persists, provide our support team with your logs:

  1. Restart Multilogin
  2. Try to recreate the issue and prompt the error message you've received before (e.g. start a browser profile, try to edit its settings, etc)
  3. Close the browser profile and / or the error message
  4. Go to "My account" and click on "Open logs directory":

A folder will open up. Archive all log files in that folder and send the ZIP or RAR file in to [email protected].

Also, we will need to test your proxy IP, port, username and password, which you can fin in the "Proxy" tab in your profile settings. Include these details in your email too.
