Mbbrowser Version Updated
【May 20, 2026】Version: 8.12.32.230
Version: v8.12.32.230
Kernel Version: 140.0.7339.248 Build 20260311
Update Level: Major / Core Update Codename: "ControlMatrix"
Version Overview
If the previous MigrationBridge release solved the fundamental question of how the browser routes traffic through proxies more reliably, this ControlMatrix release focuses on a daily operational challenge: when you have more environments, more accounts, more proxies, and more Cookie states to maintain, how do you keep the client clear, controllable, and traceable?
In real operations, teams repeat the same tasks every day: create environments, group them, clone them, assign proxies, test proxies, import accounts, maintain Cookies, check logs, back up data, manage plugins, and run automation scripts. Each task may be simple on its own, but when you manage dozens or hundreds of environments, the real cost comes from switching between tools, repeatedly confirming states, and struggling to diagnose issues after they happen.
ControlMatrix reorganizes these high-frequency workflows into a stronger client-side operation matrix.
This release covers environment operations, proxy detection, Cookie health management, email reminders, automation scripts, plugin management, UserAgent management, data backup, local logs, multi-window control, browser tiling, firewall assistance, and a large set of UI stability improvements.
1. 🧭 Environment Operation Center
📌 In one sentence: when your environments grow from 10 to 100, the client should still help you see, find, and control them clearly.
This update improves the main environment list, grouping entries, single-environment action menus, environment transfer, cloning, and session package import/export workflows.
What you will notice
- Clearer selected, hover, and highlighted states in environment lists;
- Easier access to grouping, transfer, clone, proxy, Cookie, and package actions;
- More complete session environment manager, session group manager, and session package tools;
- Better workflows for team handover, batch migration, and multi-project operations.
Better batch environment creation
The one-click batch creation dialog has been refined for users who need to create many environments at once and combine them with accounts, proxies, groups, and base configurations.
2. 🌐 Proxy Detection Matrix
📌 In one sentence: proxy testing now focuses more on whether a real public exit IP can be obtained through the proxy.
Proxy failures can come from protocol selection, account credentials, whitelist settings, proxy providers, upstream bridge status, local network issues, or the detection source itself. This update strengthens the proxy testing chain, public exit IP validation, failure hints, and batch detection stability.
| Capability | Improvement |
|---|---|
| Single environment test | Reads protocol, host, port, username, and password more clearly |
| Exit IP validation | Focuses on whether a valid public IP is obtained through the proxy |
| Failure classification | Helps distinguish unreachable proxy, auth failure, source failure, and invalid response |
| Batch testing | Improves task lifecycle, stop actions, resource release, and UI callbacks |
| Proxy pool management | Improves server manager, batch import, and batch assignment workflows |
3. 🍪 Cookie Health Center
📌 In one sentence: do not wait until accounts are logged out; see which environments are at Cookie risk earlier.
The Advanced Cookie Manager now supports Cookie / Environment dual views. Users can manage individual Cookie records or view Cookie counts, expiration status, reminder status, and smart guard status by environment.
Key improvements
- Cookie count and expiration status by environment;
- Quick filters for reminder-enabled, guard-enabled, expired, and expiring environments;
- Batch add/remove expiry reminders;
- Batch add/remove smart guard;
- More complete Cookie editing fields for modern browser Cookie attributes;
- More stable Cookie edit, import, export, extension, and statistics refresh workflows.
4. 📬 Cookie Expiry Email Reminder
📌 In one sentence: Cookie expiry becomes a manageable event instead of a surprise login failure.
This release improves Cookie expiry reminders, SMTP email configuration, fixed-time reminders, first-run verification sending, and saved reminder state display.
What changed
- Clearer reminder text, guiding users to renew Cookie state through real website login;
- Reminder settings can be saved and displayed again after reopening the client;
- SMTP configuration supports test sending;
- Fixed-time reminders can send a first verification email even when no Cookie is currently expiring;
- Reminder, SMTP, and smart guard operations are logged for easier support diagnosis.
💡 For websites using JWT, server-side sessions, or advanced risk control, changing local Cookie time is not the same as real renewal. The correct path is to log in again inside the corresponding environment so the website can issue a new valid session.
5. 🤖 Automation, Plugins, and UserAgent
📌 In one sentence: repeated operations should move into tools, scripts, and reusable workflows.
This update improves the automation script manager, automation API entry points, browser plugin manager, and UserAgent manager. Developer teams can integrate Mbbrowser into their own systems, while non-developer users get clearer management for scripts, plugins, and UA libraries.
Typical scenarios include batch page opening, account status checks, repeated login or inspection workflows, per-environment plugin loading, UA library management, and integration with Puppeteer, Selenium, Playwright, or internal systems.
6. 🧰 Backup, Logs, and Diagnostics
📌 In one sentence: when something goes wrong, you should be able to trace what happened.
This update improves data backup, session package management, local environment logs, and Cookie operation logs. These tools help with computer migration, team handover, data recovery, and customer support troubleshooting.
Log coverage includes
- Environment operations and exception records;
- Cookie edit, delete, extension, import, export, and copy actions;
- Expiry reminder changes and saved settings;
- Smart guard changes;
- SMTP settings, test sending, and email delivery results;
- Batch tasks, proxy detection, and key window operation states.
7. 🪟 Multi-Window Control and System Tools
📌 In one sentence: when multiple environments are open, window layout and batch control directly affect productivity.
Multi-window control, browser tiling, and firewall assistance continue to improve. These tools support simultaneous multi-environment operations rather than isolated single-window usage.
Benefits
- Easier layout and observation of multiple browser windows;
- Better batch focus, switching, text input, and page operation workflows;
- Firewall manager helps diagnose local network, proxy connection, and browser runtime restrictions;
- Combined with proxy testing and environment logs, network issues become easier to locate.
8. 🎨 UI Experience
📌 In one sentence: this release improves not only features, but also the interface details users touch every day.
Main windows, menus, dialogs, list controls, icons, multilingual text, and window stability were improved. Function menus, group menus, single-environment action menus, Cookie menus, proxy menus, and package import/export menus are clearer.
Key UI improvements
- Better hover background, selected background, and selected indicators in list controls;
- Fixes for selected-state indicators being covered by backgrounds;
- More balanced dialog height, field layout, bottom buttons, and help text;
- New buttons, menus, log action names, and dialogs integrated into multilingual resources;
- More stable UI refresh after closing windows, ending batch tasks, and switching states.
Version Summary
v8.12.32.230 ControlMatrix is a core upgrade for large-scale account operations.
It brings environment management, proxy detection, Cookie login state, email reminders, automation scripts, plugin extension, UserAgent, data backup, diagnostic logs, multi-window control, and UI stability into a more complete client-side operation workspace.
If you use only a few environments, you will notice clearer UI, more reliable proxy testing, and better reminders. If you manage dozens or hundreds of environments every day, the bigger value is that batch actions are smoother, states are more visible, issues are easier to trace, and team maintenance costs are lower.
We recommend considering this upgrade only when necessary, and only as a same-kernel-version upgrade. Before installing a new version, you must first confirm your current Mbbrowser kernel version: you must upgrade on the same kernel version. For example, if your previous kernel version is 140.0.7339.248, the installer you upgrade to must also use kernel version 140.0.7339.248; otherwise, a kernel mismatch may create a risk of account credential loss.
If you operate multiple accounts, cross-border business, social media matrices, advertising accounts, e-commerce stores, or automation workflows, do not import all business data into the new version immediately after installing the same-kernel latest version. Import a small number of environments first, verify stability, and then gradually proceed with broader use.
