I am looking for a programmer who can fix a Chrome extension or build a new program.

Budget: 10000 USD Deadline: 2 days

Well, it's more like this - the estimate for the first stage is 10,000 UAH and 2 days. This is not an attempt to guess the entire project from the video, but a normal check - to raise the extension, find the malfunction, understand whether it can be carefully fixed or if it's cheaper to build a new program.

From Drive, it is clear that the link opens as MP4 with a demonstration, not as the original zip. In the video, the FB Groups Manager extension works over Facebook, inputs a list of groups, keywords, and search parameters, then goes through the results. Here, Facebook limits, selector stability, and account protection are important; otherwise, the automation will last from Friday until noon =/

I can start with diagnostics and provide a short technical conclusion - repair, partial redesign, or a new version. Am I correct in understanding that the current search scenario for groups and result output needs to be preserved, rather than just making a visual correction to the extension? And the second point - do you have the zip with the source files, or is there only the installed version in the browser?

Grisha, I can quickly figure out your Chrome extension: I will find the cause of the failure, fix the logic, and test it on real scenarios. If the current code turns out to be too problematic, I will suggest a careful redesign or a new version while preserving the necessary functionality. 7 years in web and application development help me quickly identify bottlenecks and bring such tasks to a stable result. I am ready to discuss the details regarding the archive.

Budget: 100 USD Deadline: 2 days

I can fix the current one or create a new one, the task is clear, I have written 200+ extensions for automation.

Hello! I watched the video, but I didn't quite understand where exactly it should be sent?

Budget: 12000 USD Deadline: 5 days

We already have a nearly ready database for similar Chrome extensions and automation of work with Facebook groups, which can be quickly adapted and launched here on the marketplace =)

We can fix the existing extension or build a new version if it's easier to rewrite the code. From the attached file, I see it's not an archive, but a video - there is FB Groups Manager over Facebook search, fields for groups, keywords, and launching collection.
Based on my feelings, the first working stage is an audit of the source code, restoring the logic of bypassing, checking Facebook authorization, protection against duplicates, and issuing a stable version.

> Benchmark - from 12,000 UAH
> Deadline - 5 working days for diagnostics and fixing the basic version
> If a new program needs to be made with an action log, limits, queues, export, and settings for multiple accounts - then the estimate will be higher after checking the source code.

I would like to clarify two things.
> Is there the source code of the extension or just the installed version?
> What is currently broken - group search, result collection, publication, authorization, or the launch button?

Similar cases in meaning.
> https://business.ingello.com/vorfahr - automation of the process and logic of actions around data
> https://business.ingello.com/fractal - agency automation and scenarios where the system itself leads the steps
> https://systems-fl.ingello.com - who we are and what systems we create

In touch, we can start with a quick technical analysis and after that decide whether to repair or rebuild from scratch. Well, it's more like this - if the old code is alive, then we can keep it simple and fix it; if everything is on crutches, rewriting will be cheaper in terms of time. Expand

Budget: 120 USD Deadline: 3 days

Hello. I can take a look at the current Chrome extension, find the cause of the malfunction, and make the necessary adjustments, or suggest a more stable option if it would be quicker to build a new version. I will check the current logic, fix the problematic areas, and test the main use cases to ensure the extension works stably again.

Hello! I specialize in Claude. I can try to fix it; if it doesn't work, I will suggest another option. We can do it in Python + Playwright - this emulates human actions on a website. I can complete your task in any case. Write to me, and we will discuss.

Budget: 25000 USD Deadline: 7 days

Hello, Grisha!

In order to offer the most suitable solution, please clarify:
1. What specific problems are occurring with the current extension?
2. What functionality should it perform?
3. Do you want to maintain the current architecture and logic of the extension, or are you considering the possibility of creating a new solution from scratch?
4. Do you have access to the source code of the extension?
5. What deadlines and budget are you considering for completing the task?

My approach is as follows:
1. I conduct an audit of the current extension, identifying and fixing errors.
2. If necessary, I design and create a new program based on your requirements.
3. I ensure quality testing and support to avoid similar problems in the future.

Grisha, please write your answers to the questions in private messages — let's see how best to solve your task. Expand

Good afternoon. I am ready to complete this project and have extensive experience in developing various applications.

Budget: 100 USD Deadline: 2 days

Hello
I’m very interested in your Chrome Extension project. I have strong experience building modern web applications and browser-based tools using JavaScript, TypeScript, React, Node.js, and API integrations.

I have worked on browser automation, custom dashboards, authentication flows, REST APIs, cloud-based backends, and performance optimization. I’m also experienced with Chrome Extension architecture including background scripts, content scripts, messaging, storage, and third-party integrations.

In addition, I’m familiar with AI-powered features, automation workflows, and scalable backend systems using Azure and AWS. I focus on clean, maintainable code, responsive communication, and reliable delivery.

I’d be happy to discuss the project requirements and help build a stable, user-friendly Chrome Extension solution.

Regards

Welcome! We are a team of developers with a 4-year background, and fixing bugs in JavaScript code is our daily task. Our skills in layout and working with web interfaces allow us to clearly understand how the plugin interacts with the website's code and where the failure occurs.
Check out our completed works at farfieworldwide.com, freshagro.com.ua, and espressolab.com.ua, where interactive elements and scripts work flawlessly.
If your Chrome extension has stopped working or is throwing errors in the console, we will quickly find and fix the problem.
Let us know which specific function of the extension is broken, and we will immediately start working on a solution.

Budget: 300 USD Deadline: 3 days

The minimum cost for such a task usually starts from $150–300 if:
- integrations are already implemented
- only production OAuth settings need to be fixed
- there is no complex backend logic
- the problem is with the callback URL, scopes, app review, verification, or publish status.

However, if it is necessary to:
- redo the authorization
- fix the backend/frontend flow
- perform App Review for Facebook / TikTok
- set up the OAuth consent screen in Google
- go through moderation / security review
- complete mobile auth or webhooks

then the actual cost may be $400–1000+.

For the freelance offer, you can write at least:
- Rate: $20–35/hour
- Minimum estimate: from 8–12 hours

That is:
- minimum check: ~$200
- minimum term: 1–3 days.

Since the problem "works only for test accounts," it is most likely that:
- the Google app is not moved to Production
- the Facebook app is in Development mode
- the TikTok Login did not pass review or whitelist restriction
- incorrect redirect URI/domain verification.

This is a typical problem with OAuth integrations. Expand

Debugging (Bug Fix): I will fix errors in the console, issues with authorization, data parsing, or interaction with APIs.

Optimization: I will speed up the performance of content scripts so they do not slow down page loading. There is a large o Expand

I looked at the archive — this is a Chrome extension for working with FB groups (parsing/automation). I can either fix the existing one or rewrite it from scratch if there is accumulated technical debt.

What exactly is not working right now — a specific error in the console, or does the extension not launch at all?
