Hello, I read your post carefully and this is very clear: you need 4–5 lightweight browser extensions built properly for Chrome, Edge, and Firefox, then published cleanly with store-review rules in mind. This part is important because simple extension logic is usually easy, but store compliance, permissions, manifests, assets, and submission details are where many projects get delayed. I can help with full extension development flow: shared codebase for all 3 browsers, manifest/platform adjustments, UI polish with HTML/CSS/JS, testing, packaging, and submission support. I also understand the need for fast turnaround and clean work, not generic coding. If needed, AI can be used only to speed repeated parts, while keeping manual review for quality and approval safety. The most sensitive part in this kind of work is avoiding rejection from Chrome Web Store, Edge Add-ons, and Firefox AMO due to permission scope, unclear functionality, or policy mismatch. I handle this by keeping extensions lightweight, transparent, and store-friendly from the start. If you send the extension concepts, I can review scope quickly and organize the build in a systematic way. Please message me, and I will reply with a clear plan for your extensions.

Hi, I can build and prepare 4–5 lightweight browser extensions for Chrome, Microsoft Edge, and Firefox, including clean development, cross-browser testing, packaging, store-ready assets, and publishing support. The best solution is to first review the required extension features, permissions, UI flow, target stores, branding, privacy requirements, and whether Manifest V3 is suitable for all versions. Then I’ll build reusable extension code, adapt it for Chrome/Edge/Firefox where needed, test installation and behavior, prepare store listing materials, and support submission until review approval. I’m comfortable with JavaScript, HTML, CSS, browser extension APIs, Chrome Web Store submissions, Microsoft Edge Add-ons, Firefox AMO, Manifest V3, permissions review, background/service workers, content scripts, popup UI, API integration, debugging, and store compliance requirements. Deliverables can include: * 4–5 lightweight extensions * Chrome, Edge, and Firefox compatible builds * Clean source code * Store-ready ZIP packages * Icons/screenshots/listing text * Privacy policy guidance if needed * Testing before submission * Publishing support * Fixes for review feedback Estimated timeline: 5–10 days for 4–5 simple extensions depending on feature scope. Rate: fixed per extension or total project, based on final requirements. Best regards Ankit

4-5 lightweight extensions across Chrome, Edge, and Firefox is mostly a packaging and review-compliance job once the core logic is simple — each store has its own manifest quirks (Manifest V3 for Chrome/Edge, Firefox's slightly different permissions model) and review checklist, so I'd build once against a shared codebase where possible and adapt the manifest/packaging per store rather than rewriting from scratch each time. I use AI tooling regularly to speed up boilerplate and iteration without cutting corners on review compliance. I've built browser extensions and frontend tooling (JS/HTML/CSS) before, though I don't currently have published store links to share — happy to build one as a quick proof before you commit to the full batch, if that helps de-risk this for you. What do the 4-5 extensions actually do, and do you have a rough idea of total scope per extension (single feature vs multi-feature)?
