CAPTCHA Solver Firefox Extension: Compare Options
Compare CAPTCHA solver add-ons for Firefox — by supported CAPTCHA types, AI vs human solving, and pricing.
Overview
CAPTCHA solver add-ons for Firefox
Firefox uses its own add-ons store (addons.mozilla.org), and several CAPTCHA providers publish a Firefox build alongside their Chrome extension. The behaviour is the same: detect the challenge, solve it via the provider backend, and inject the token into the page.
When comparing Firefox add-ons, check that the provider explicitly supports Firefox, which CAPTCHA types are covered, AI vs human solving, and pricing. Open a provider profile to see the details and the official add-on link where available.

How to evaluate a CAPTCHA solver
Supported CAPTCHA types
Confirm the provider explicitly supports the exact challenges you face — not just a generic fallback.
Solve speed
Average solve time directly affects throughput in automated and real-time flows.
Success & received rate
Higher reported accuracy means fewer retries and lower effective cost per solve.
API & SDK coverage
Check REST endpoints, official SDKs for your language, and the quality of documentation.
Pricing model
Per-solve and per-thread models scale differently — compare the price for your CAPTCHA type at your volume.
Concurrency & support
Concurrency limits cap throughput; responsive support matters when integrations break.
