Chrome extension for sending messages in Facebook Messenger

Budget: 500 EUR Deadline: 30 days

I am implementing a lightweight extension on Manifest V3 that simulates character-by-character input through keyboard events, so that your messages do not appear to Facebook's algorithms as an instant paste from a spam bot.

What method do you plan to use to bypass the dynamic change of selectors in the messenger, so that the extension does not "break" after a week, and your account does not get banned due to overly obvious automation on non-existent elements?

Budget and deadlines are in personal correspondence. 🤝

Good day!
I am ready to quickly complete the task.
Write to me in private messages, we will discuss the terms.

The task is clear, a simple extension can be implemented through a content script that will automate work in the web version of Messenger (searching for dialogs, inserting text, and sending with a delay).

I have already worked with scripts and similar automation in the browser, so there will be no problems with implementation.

Hello, Yuriy! The task is clear — Chrome Manifest V3, popup with textarea + file input, content script for Messenger automation.

Important: Facebook actively opposes automation, so for reliable text insertion, an InputEvent is needed, not a direct write to value. I also recommend randomizing the delay (3–8 seconds) — this will reduce the risk of account ban.

I will do it for 60 EUR / 2–3 days. Details in private messages.

Understanding the task: it is necessary to develop a simple extension for Chrome that will send identical messages in Facebook Messenger with delays for naturalness. This is a good idea, but there are some points that need to be discussed.

I suggest using JavaScript and the Chrome API to create the necessary functionality. The extension will process a list of user IDs and automatically send messages. The main thing is to think through the flow of actions to avoid blocks from Facebook and maintain the naturalness of sending. The logic will be simple but will require careful attention to delays and user processing.

Among the risks: possible limitations on the number of messages sent at once, which could lead to account blocking. It is also necessary to clarify which specific IDs will be used (additional validation may be required).

I propose to discuss the details and launch the project next week. I am confident that I can handle this task.

The web version of Messenger has protection against automation, so it is important to make the solution as cautious and "human-like" as possible to avoid blocks.

Why I will perform this task better:
I am not just writing an extension; I am immediately laying down safe and stable logic for operation considering Facebook's restrictions. The main mistake in such tasks is to create a "blunt" auto-click, which quickly leads to account blocking. I will implement a scenario that simulates real user actions: with pauses, variability, and page state control. Special attention is paid to simplicity—without overloaded architecture, but with clean and understandable easily maintainable code. You receive not just an MVP, but a working tool that can be used without constant refinements. It is also important that I take into account the instability of the DOM in Messenger and make the logic resilient to interface changes. As a result, you get a simple but reliable solution that performs the task without unnecessary risks and complexity.

Good day! I am ready to develop a simple Chrome extension for automatic messaging in Facebook Messenger. I have experience with browser extensions and web automation. I will implement the functionality according to your technical specifications, including uploading a list of IDs and sending messages with a delay. Please write to me in private messages to discuss the details.

Budget: 40 EUR Deadline: 3 days

Good day, Yuri!
I will create an extension directly on messenger.com. You enter the text, upload a list of IDs, and click start. After that, everything happens automatically: it opens each chat in turn, inserts the message, and sends it. The delay between sends can be adjusted from 2 to 60 seconds, so it doesn't look like a bot.
The interface is minimalist: a text field, file upload, start/stop buttons, and a progress log. No third-party libraries. The input field in Messenger is a contenteditable div, so I work with it through browser commands, not directly. This is more stable.
I will provide the full code with comments in Russian. Installation takes 1 minute through developer mode.
I want to clarify a couple of details in private messages. Please write.

Greetings! Your task is clear to me. I am ready to develop a lightweight Chrome extension that will automate sending messages to your list of IDs. I will implement the upload of a text file, message input, and an algorithm for sequentially searching users with a customizable delay (Random Delay) to make the actions appear as natural as possible for Facebook's security algorithms. The code will be clean, without unnecessary libraries, ensuring fast performance. However, it is important to consider that Facebook constantly updates its protection and page structure, so I will set up flexible selectors for finding dialog elements. The cost of developing such a solution will be €75 and the implementation time will be 3–5 days, including the testing phase. I will need examples of IDs (link format or numerical identifiers) and clarification on what limit of messages per day you plan to send, so I can properly set the intervals. I am ready to start creating the architecture of the extension!
