Normally, a browser core should be downloaded within 10 minutes. In this article you will learn what you can do if this process takes longer. 

Check 3rd-party apps

3rd-party apps

Apps like antivirus programs, firewalls, VPNs, or proxy tools (for example, Proxifier, SocksEscort) can interfere with Multilogin.

Here are some quick fixes:

  • Uninstall these apps
  • If you do need them, disable the apps temporarily or add Multilogin to their whitelist in the settings

This should help resolve the issue and keep everything running smoothly!

How to resolve conflicts with 3rd-party apps on Windows

Antivirus apps

  1. Go to “Settings” → “Privacy & security” → “Windows Security” → “Virus & threat protection”

  1. Go to “Settings” → “Privacy & security” → “Windows Security” → “Firewall & network protection”

Turn off VPN extensions in browser: don't forget to check and turn off VPN extensions that you installed in your browser, for example, Chrome:

 
 

How to resolve conflicts with 3rd-party apps on macOS

macOS security system

If the application got restricted from the macOS security system, you can access it by the following way:

  1. Open “System Settings” → “Privacy & Security” → “Security”
  2. Click “Open anyway” for the apps

It is also recommended to change “Allow applications from” value to “App Store & Known Developers”.

Antivirus apps

  1. Go to “Finder” → “Go” → “Application”
  2. Right click the antivirus apps → “Move to Trash/ Move to Bin”

Some antivirus software for macOS has their own uninstallation tool (e.g., Kaspersky and Avast). 

 
 
 

Firewalls

  1. Open “Apple menu” → “System Preferences” → “Security & Privacy”
  2. Go to the “Firewall” tab and click “Turn off Firewall”
 
 

VPNs

Uninstall VPN applications:

  1. Go to “Finder” → “Go” → “Application”
  2. Right-click the VPN apps → “Move to Trash/ Move to Bin”
Zight 2025-2-8 at 2.03.24 PM

Disable VPN applications: right-click the VPN apps on the menu bar → choose “Quit <name of app>”. 

Turn off VPN extensions in browser: don't forget to check and turn off VPN extensions that you installed in your browser, for example Safari:

  1. Choose “Safari” → “Settings” (or “Preferences”) → click “Extensions”
  2. To turn off an extension, deselect its checkbox
 
 

Check the ISP

ISP

Sometimes, internet service providers (ISPs) block proxy providers or even Multilogin itself. Here’s how to test and work around it:

  • Try connecting through a VPN: this can bypass ISP restrictions
  • Switch networks: use a different Wi-Fi, or turn your phone into a hotspot with mobile data
  • Check your speed: if your current ISP is slow, changing networks might also improve performance.

If the issue resolves with these steps, it’s likely your ISP causing the trouble. 

Reconnect the agent

This issue might also occur because of the agent app glitch. Restart it to be on the safe side.

Refresh components

Deps

This action is completely safe! It refreshes the app components needed for Multilogin to work smoothly. No data will be lost during the process, so you're good to go! 😊

 

Avoid deleting the mlx folder, as this may result in a complete or partial data loss. 

 
  1. Disconnect the agent
  2. Go to the mlx folder:
    1. Windows: C:\Users\%username%\mlx
    2. macOS: /Users/%username%/mlx
    3. Linux: /home/%username%/mlx
  3. Delete the deps folder
  4. Connect the agent to get things rolling
  5. Start any profile – this will automatically kick off the components download process
Your browser does not support HTML5 video.

Check your system language

In some cases, the download process can be stuck if your OS language is not English.
