About the project

Site mozilla-firefox-portable. ru. uptodown. com is an Uptodown directory page dedicated to distributing a portable version of the Mozilla Firefox browser. This is not an official developer resource, but part of a multi-platform application store that specializes in providing free access to software. The main purpose of the page is to give users the opportunity to download version 151. 0. 2. 0 for Windows for free.

The project is aimed at those who value mobility and independence from the hard drive. Here we offer a tool based on the original Mozilla development, but adapted for launching from external media. The developer of the specific ported build is listed as John T. Haller, which makes this product different from the standard setup.

Main directions

The key task of the project is to ensure that the browser works without the need for installation. The user can copy the program to a USB drive and run it on any computer. This solves the problem of linking settings and history to a specific device.

  • Security and privacy:The description emphasizes the absence of advertising and the presence of built-in security features such as pop-up blockers.
  • Functionality:All the basic features of the original are retained: working with tabs, a download manager and support for modern web standards.
  • Availability:The application is available in Russian and is positioned as a free tool with a license that does not require payment.

Site Features

The Uptodown page serves as a technical showcase. The file metadata is collected here: the size is 173.51 MB, the format is EXE, and the publication date of version 151.0.2.0 is given as May 29, 2026 (judging by the text, this is a future or test date in the context of the source). A SHA256 hash is provided for integrity checking.

It is interesting that the site contains a section with previous versions, ranging from 147. 0. 4 to the current one. This allows users who need older stable builds (for example, for compatibility with old plugins) to find the version they need without searching the entire Internet. User reviews range from 2009 to 2022, indicating a long history of community use of this particular portable build.

The page contains standard store elements: application rating (3.9 out of 5 based on 14 reviews), add to favorites buttons and the ability to leave a comment. Editorial review is carried out by Álvaro Toledo, which adds an element of trust to the platform's content.
