What is mibextid?
What mibextid does
When you Share a link from the Facebook app (or Messenger, sometimes WhatsApp depending on the version), Meta appends ?mibextid=<token>. The token encodes which app, which session, and is joined server-side to your Meta account.
mibextid vs fbclid
Two tokens, two pipelines, both safe to strip: fbclid lands on links *clicked from Facebook ads* (paid-attribution; the destination's Meta Pixel reads it). mibextid lands on links *shared via Meta apps* (share-attribution; Meta reports the click back from the share-graph).
The same destination URL can carry both — fbclid because someone clicked an ad, mibextid because they re-shared it. Strip both as a pair.
How LinkClean removes it
Default-on in LinkClean's social catalog. Same vendor-specific-token-no-functional-use logic as fbclid / ttclid / yclid.
Why it shows up everywhere
Anyone sharing news, recipes, products, or videos via Facebook or Messenger adds mibextid to the link without knowing. Most people forwarding “look at this” links via Messenger or SMS are unknowingly amplifying Meta's measurement graph.
Frequently asked
What does mibextid stand for?
Best guess from Meta's app code: a “Mobile Internal Browser EXTension ID” or similar internal abbreviation; Meta has never published an official expansion. The behavior is the documented part.
Does removing it break anything?
No. The destination doesn't read it — only Meta's analytics infrastructure does, after the page has loaded.
Why is mibextid different from fbclid?
They serve different purposes. Per-click identifiers (fbclid, gclid) credit ad spend. Per-share identifiers (mibextid, igshid) measure organic sharing. Meta cares about both — strip both.
Does any destination site ever use mibextid?
No (verified across every site in our catalog). It exists for Meta's measurement only.
Clean tracking on iPhone, in one tap.
LinkClean strips ~80 vendor-specific tracking parameters from any link, from any app's share sheet — and preserves functional ones like hl, t (YouTube timestamp), and q (search). No account, on-device.
