Best Extensions to Download All Images for Firefox (2025)

Best Extensions to Download All Images for Firefox (2025)Downloading images from webpages—whether for research, archiving, design inspiration, or offline browsing—can be tedious if done one by one. Firefox’s extension ecosystem includes several tools that automate bulk image downloading, filter unwanted files, and preserve folder structure. This article reviews the best extensions in 2025, explains key features to look for, provides usage tips, and compares pros and cons so you can pick the right tool for your needs.

Before choosing an extension, consider these criteria:

Speed and reliability — handles large pages and many simultaneous downloads without crashing.
Filtering options — include/exclude by file type, size, filename patterns, dimensions, or URL.
Recursive/site crawling — ability to follow links to download from multiple pages or an entire site (beware of server load and site policies).
Output control — folder naming, preservation of source paths, and conflict handling.
Download manager integration — works with Firefox’s built-in downloader or external download managers.
Privacy and permissions — minimal permissions, open-source when possible, and a clear privacy policy.
Active maintenance and compatibility with latest Firefox versions.

Below are the best extensions (in no particular order) based on functionality, user experience, and maintenance status as of 2025.

Respect copyright: only download images you have the right to use. For copyrighted content, check licensing or obtain permission.
Honor robots.txt and site terms: when using crawlers, enable options that respect robots.txt and set polite crawl rates.
Avoid overloading servers: set crawlers to low concurrency and delays between requests.
Watch privacy: prefer extensions with minimal permissions and transparent privacy policies. If an extension requests broad access to all browsing activity, consider alternatives.

Use dimension filters to exclude tiny tracking or spacer images (e.g., min width/height 200px).
Combine with an external download manager for very large batches (e.g., integrate with a manager that supports segmented downloads).
When source path preservation is important for organization, choose an extension that can retain directory structure or export a manifest.
For reproducible workflows, keep a template of filter rules (many extensions let you save presets).

Missing images: some images are loaded dynamically via JavaScript or lazy-loaded. Reload the page, scroll through it, or use the extension’s “load all images” feature before scanning.
Blocked downloads: browser settings or antivirus software may flag mass downloads—allow the action if you trust the site and extension.
Duplicate filenames: use rename masks or enable “skip duplicates” to avoid overwriting.
Extension not compatible with Firefox version: update Firefox and the extension; check the extension’s changelog for known issues.

If you want a feature-rich, professionally designed tool with strong filtering: choose ImageAssistant — Bulk Image Downloader.
For mature download management with advanced queueing and rename masks: choose DownThemAll! (Modernized).
For fast, simple page-level bulk saves: choose Batch Image Downloader or Save Images to Folder.
For site-wide archival tasks: choose ImageCollector — Site Crawler & Downloader, and use it responsibly.
