Take a Quick Look
With the latest upgrade of AdsPower, the Firefox core has been updated to version 135, introducing powerful new features that enhance mobile device simulation and security settings. Try it now!
Keeping up with the latest technological advancements, AdsPower FlowerBrowser has officially upgraded its Firefox core to version 135. This update brings significant improvements, particularly in mobile device simulation and security features, ensuring a more seamless and versatile browsing experience for users.

Key Features of the Firefox 135 Upgrade
1. Support for Simulating iOS and Android Mobile Devices
A major highlight of this update is the ability to simulate iOS and Android devices, a feature that was previously unavailable in FlowerBrowser.

Before updating to 135 version: when you select FlowerBrowser, the Android and iOS options cannot be clicked and there is a note - Requires Firefox 135 or higher version kernel.

After installing Firefox 135: the Android and iOS icons can be selected if you are creating a FlowerBrowser profile.

Note:
- Requirement: Firefox 135 or a later version must be selected as the core browser.
- When choosing "Auto" and specifying the operating system as Android or iOS, the User-Agent (UA) will be randomly assigned between versions 133-135, and the core version will automatically match Firefox 135.
2. New "Disable TLS Features" Option
Security remains a key focus for AdsPower. "Disable TLS Feature" was first introduced in AdsPower's Chrome core update in February and now this upgrade extends it to Firefox 135.

Note:
- Requirement: Requires Firefox 135 or later.
By disabling specific TLS characteristics, users can achieve a higher level of anonymity, making it harder for websites to track browsing behavior based on TLS fingerprints, offering an edge over competitors who lack support for this feature in Firefox-based environments.
