Sahibinden Fiyat Geçmişi, developed by Fiyat Gecmisi, brings historical listing context to shoppers on sahibinden.com by showing past changes directly on advertisement pages. The extension helps users inspect how asking figures moved over time, surfacing dates and numeric adjustments alongside the current listing. It addresses buyers searching for vehicles or property in Turkey, giving concrete historical evidence to inform offers and reduce guesswork during negotiations.

How it fits into a typical browsing session

The extension installs into Firefox on desktop and compatible Firefox for Android, placing its interface inside the marketplace pages so you keep one workflow when researching ads. Because it augments the site rather than opening a separate app, users can compare multiple listings in the same browser tab. Some users report occasional temporary access restrictions on the marketplace when tracking tools are active, so brief interruptions during a shopping session can occur.

Where the historical data comes from and what that means

The developer maintains a central index and a companion website that enables lookups by listing ID, so the extension depends on those collected records instead of only local logs. This sourcing gives it historical coverage for many listings, but it also means gaps exist where a listing has not been indexed yet. The extension is an independent third-party tool and is not affiliated with the marketplace company.

Who benefits on Firefox and how it compares in the add-on ecosystem

For people in Turkey actively browsing real estate or vehicle ads, the extension is a practical way to add context to asking figures without switching tools. It is one of the few dedicated tracking add-ons for the Firefox ecosystem and keeps a positive rating on the Firefox Add-ons store. Users looking for exhaustive coverage should expect occasional missing entries and may combine site lookups to fill gaps.

To sum up, a useful companion for informed buyers with a small coverage caveat

To sum up, Sahibinden Fiyat Geçmişi is a pragmatic option for active Turkish shoppers who want historical context while browsing listings; it strengthens negotiating confidence but does not guarantee history for very new ads. Pro tip: when a listing shows no history, paste its listing ID into the developer's lookup page to check whether records exist outside the in-page view.
