Mbbrowser Anti-Association Browser Release Notes
【November 5, 2026】Version: 9.62.20.208
Version: v9.62.20.208
Highlights: First Windows 64-bit release · Smoother route switching and first-login selection · Fingerprint and backup history easier to review · Safer account, UA, and web automation tasks
Overview
When you manage many browser environments, the time-consuming part is often not opening a browser. It is checking which account you are working on, finding an old check result, handling extensions and backups, or figuring out what happened after an operation failed.
Version 9.62.20.208 refines these everyday tasks.
Proxy and group operations are clearer, fingerprint check results can be reviewed later, and account or extension tasks are less likely to leave partial changes behind. Logs can be filtered by date, while line selection and window handling have also been refined. Start with the feature you use most; you do not need to learn everything at once.

First Windows 64-bit release: more room for demanding setups
This is the first 64-bit Windows release of Mbbrowser. The x86 version remains available for older systems and compatibility needs. An x64 browser process can use a much larger memory address space, which gives multi-environment work and complex pages more room before memory limits become a bottleneck. We do not claim a fixed speed multiplier: page response time still depends on the computer, network, website, and browser core.
| Comparison | 32-bit (x86) | 64-bit (x64) |
|---|---|---|
| Best fit | Older systems or 32-bit compatibility needs | 64-bit Windows and multiple or memory-heavy environments |
| Memory headroom | Limited by the address space available to a 32-bit process | Can address more memory, which may help under heavier workloads |
| Multiple environments | Can run several, but process memory may limit heavier sessions | More room under memory-heavy loads; the usable number still depends on installed RAM and workload |
| Page speed | Depends on hardware, network, site, and core | More headroom does not guarantee every page loads faster |
Choosing a download: x64 Windows users who run several environments can try x64 first. Keep x86 when compatibility requires it, and match the browser core when upgrading existing environments.
1. 🧭 Environments, groups, and proxies: clearer bulk work
📌 In one sentence: confirm which environments you are changing, then manage their proxies and groups with fewer surprises.
Bulk proxy tasks keep a snapshot of the environments and account information selected for that operation. If you change accounts, close a window, or refresh a list, a late result is less likely to be applied to a different environment. Group renaming and moving also use stable environment identities; when saving fails, the previous choice is preserved where possible.
After a line is changed, the companion service can follow the current line. On first sign-in, Mbbrowser can also try an available configured line; if none is suitable, it continues with the existing route. The line window shows its local list first and checks for updates in the background.
- It is easier to see which environments a bulk action will affect.
- Download progress reflects data actually received instead of jumping forward and backward.
- Speed checks, line changes, and remote list updates are less likely to interfere with one another.
Proxy import and bulk assignment: handle multiple environments at once
Proxy text and file imports now run in the background and are checked after saving. If reading or saving fails, the new batch is rolled back and the existing list is kept. Search by proxy address, port, account, or type; port input is checked as a complete valid number.
You can select several proxies and environments, assign them in order or at random, or remove existing bindings. The targets are fixed before submission and environment versions are checked; conflicting actions are limited while the operation runs. Each proxy request follows its configured timeout, and usage reports are queued in the background to avoid holding up the interface.
Route switching, refined: keep the login window responsive
Previously, switching routes during login could leave the login window waiting several seconds for a network handshake. Route confirmation and service synchronization now run in the background with time limits. If one address does not respond, the client can try another available address and release stale connections sooner.
Routes are saved by node ID, so two nodes that share an address are still treated as different choices. If the companion service restarts or misses an update, the client can confirm the latest selection again instead of letting an older notice replace it.
First login: probe several routes at once
On the first login, Mbbrowser probes candidate routes concurrently and prefers the first one that returns a valid response. The check takes up to about three seconds and does not send your account password. The choice is marked complete only after login and the first full data sync succeed; otherwise the previous route stays in place and the client can try again later.
2. 🧾 Fingerprint history: review checks later
📌 In one sentence: keep check results with the matching account and environment so they are easier to review later.
Fingerprint check records are stored separately by account, user, server, and browser environment. You can review recent results or remove records you no longer need; a new result does not simply replace the previous history.
If a check does not complete, the existing list stays available and the status is easier to understand. You can confirm which environment and check you are looking at before deciding whether to try again.
A practical habit
Give each environment a recognizable name and note what you were checking. It is easier to distinguish accounts and environments when you return to the history later.
Fingerprint checks now keep separate local snapshots for the account, user, server, and browser environment that started the check. You can review recent results, see whether recorded details changed, and remove individual or old records without replacing the previous snapshot.
Background queries are tied to the account and environment that started them. Switching accounts, closing the window, or a timeout is less likely to attach a late response to the wrong environment. When a check fails, existing records stay available so you can review them before retrying.
3. 🔐 Accounts, cookies, and extensions: better handling when something fails
📌 In one sentence: imports and installs provide clearer checks and are less likely to leave incomplete changes.
If a bulk account update cannot be saved or verified, Mbbrowser attempts to restore the previous information. Passwords stay hidden unless you choose to reveal them.
Cookie and bookmark imports remain associated with the account and environment that started them, even if a window is closed or another operation begins. Extension files and settings are checked before installation, and progress is clearer. A task is marked successful only after installation is confirmed.
- An Excel file that is in use is distinguished from other read errors.
- A failed extension save does not immediately clear the existing list or cache.
- If a backup lookup fails, previous results remain available and you can retry.
The environment login-account manager now checks batch edits against the browser's saved login data. Important files are read back after writing; if a step fails, the previous files and list are restored where possible. Existing verification and platform details are preserved during edits.
The User-Agent (UA) manager trims extra spaces before checking imported entries for duplicates. Reopening older UA records no longer changes their original added date, and built-in templates use a separate cache from your own list.
4. 🕓 Logs, backups, and check results: find what you need sooner
The log window now offers a date-range filter. Choose a start and end date to narrow the records. When deleting logs, Mbbrowser first keeps a snapshot of the selected entries and performs the deletion in the background. The list updates after success; if deletion fails, the records remain and a message explains what happened.
Fingerprint history and backup results also follow the active account, environment, and search conditions more consistently. This reduces the chance that an older result replaces the list after you switch accounts or languages.
For example: choose the day you want to review before opening login records, instead of searching through a long list one entry at a time.
Backup searches now keep the account, server, and date filters from the time the request began. A late result is less likely to replace the list after an account switch or window close; on failure, the previous list stays available with a retry option. Search status is shown separately from backup or restore progress, and changing the interface language keeps the current selection and progress.
5. 💻 Windows and daily controls: get to work with fewer interruptions
MbAgent opens automatically after the first successful sign-in only. It will not keep popping up on later sign-ins, and you can still open it manually from the existing entry. Renewal access is easier to find for trial and free accounts, and the main window now has a shortcut menu.
The date-range button in the log window is visible again. The list requests a full layout refresh after loading, helping keep the headings and records aligned. Mixed Chinese and English text, drop-down widths, and pop-up placement across multiple monitors have also been refined.
Long notices can be scrolled, and tray notifications, startup prompts, and window cleanup have been improved. Windows 7 users receive clearer preparation prompts for required components and can follow the displayed instructions.
The new quick menu in the lower-right of the main panel gathers common client and account-management entry points in one place.
Its icon resources now cover the default, 150%, and 200% display scales so the menu can load the matching asset.
An intermittent black screen in the Mbbrowser main panel during MbAgent web automation has been addressed. The automation page now follows the component's ready state, with the existing browser-page fallback available when the automation component cannot be prepared.
6. ✨ Start with one task you use every day
If you manage several environments, start with proxy groups. If you check environments often, open fingerprint history. If you maintain extensions or backups, watch the operation status and failure messages. To find activity from a particular day, try the log date filter.
These changes are meant to reduce repeated searching and uncertainty, not force you to change your workflow.

Read Before Upgrading
1. Know the software version, browser core, and system architecture
9.62.20.208 is the Mbbrowser software version. Core 140, 129, 105, 87, and 86 are browser cores. x64 and x86 indicate system architecture. They are different identifiers.
To check your Windows architecture, open Settings → System → About and look for “System type.” Windows 7/8 users should also confirm that the selected core supports their Windows version.
2. Match the core when upgrading an existing environment
In an existing browser environment, open chrome://version and check the full browser version before choosing an installer. Updating Mbbrowser does not mean you must change the core used by your current environments.
Important: do not switch the core of a business environment without checking
Switching to a different core may affect saved sign-ins or website compatibility. Back up important environments and data, then test a small number of environments first. If you are not sure which core to use, contact official support before upgrading.
3. Back up and test before moving more environments
Back up important environments and keep the original data directory. After installation, test sign-in, proxies, extensions, and regular scripts in a few environments before upgrading the rest.
4. Follow prompts the first time you use scripts or AI
If a script or feature reports that a component is missing, review the prompt and decide whether to install it. Resolve any cancellation or installation error before trying again. Test a new task in a non-business environment first.
To get started, visit the Mbbrowser website to register or sign in. If you need help choosing an installer, share your software version, full browser version, and the issue with official support.
