I will build chrome or firefox extensions for web data extraction
Fang Wang
About this gig
I build custom Chrome or Firefox extensions that help you capture visible web data from pages you use regularly, then preview, save, and export it.
I can build one-click extraction, popup UI, field selection, table/listing/card capture, local storage, history, export buttons, and multi-page workflows for public or buyer-authorized pages.
Packages:
- Basic: simple Chrome extension for one page type
- Standard: one-site Chrome extension with popup UI, settings, storage, export, and source code
- Premium: cross-browser Chrome/Firefox extension with robust selectors, multi-page workflow, documentation, and test dataset
Deliverables can include extension files, install guide, source code, and CSV/Excel/JSON/Sheets export depending on scope.
Good fits: product research, listing/table capture, dashboard exports, and repeat copy-paste work.
Please message me first with the target website, screenshots, fields, browser, login status, and desired output.
No credential theft, hidden tracking, paywall bypass, CAPTCHA circumvention, personal data harvesting, or policy-violating automation. Built for your own/team use and installed privately; public store listing is optional.

FAQ
What kind of websites can the extension extract data from?
Public pages, buyer-authorized pages, internal dashboards, listings, product pages, tables, and web apps you are allowed to use.
Can the extension work after I log in to my own account?
Yes, if you have authorized access and the website allows that use. I review login-based workflows before accepting the order.
Do I need to publish it to a store?
No. These are built for your own or team use and installed privately: Chrome/Edge via Developer mode (load unpacked), and Firefox via a Mozilla-signed unlisted build for permanent install. Public Web Store / Add-ons submission is optional and quoted separately; store accounts, fees, and approval sta
