Firefox 145 Drops Support For 32-bit Linux

BrianFagioli writes: Mozilla has released Firefox 145.0, and the standout change in this version is the official end of support for 32-bit Linux systems. Users on 32-bit distributions will no longer receive updates and are being encouraged to switch to the 64-bit build to continue getting security patches and new features. While most major Linux distributions have already moved past 32-bit support, this shift will still impact older hardware users and lightweight community projects that have held on to 32-bit for the sake of performance or preservation.

The rest of the update introduces features such as built-in PDF comments, improved fingerprinting resistance for private browsing, tab group previews, password management in the sidebar, and minor UI refinements. Firefox also now compresses local translation models with Zstandard to reduce storage needs. But the end of 32-bit Linux support is the change that will leave the biggest mark, signaling another step toward a web ecosystem firmly centered on 64-bit computing.
