FAQ
What technologies do you use?
I build Chrome extensions using JavaScript, HTML5, CSS3, Chrome Extension APIs (Manifest V3), and React for complex UIs. For backend needs, I use Node.js and Express. All extensions follow Google's latest Manifest V3 guidelines.
Will my extension work on other browsers?
Chrome extensions built with Manifest V3 also work on Microsoft Edge and Brave with minimal changes. Firefox compatibility requires additional porting work, which I offer as a gig extra.
Can you publish my extension to the Chrome Web Store?
Yes! This is included in the Premium package or available as a gig extra ($35). I'll prepare all assets — icons, screenshots, descriptions — and handle the submission process. You'll need a Chrome Web Store developer account ($5 one-time fee from Google).
What if I need changes after delivery?
Each package includes revisions (1 for Basic, 2 for Standard, 3 for Premium). Revisions within the original scope are included. For feature additions beyond the original scope, I'll send a custom offer with transparent pricing.
How long does development take?
Basic extensions take 5–7 days, Standard takes 7–10 days, and Premium/complex extensions take 10–14 days. I'll give you an accurate timeline after reviewing your requirements. I always build in buffer time to ensure quality.
