No Coronavirus for Firefox: Configure Firefox to Reduce Exposure to False Health ClaimsThe web is flooded with information about COVID-19 — helpful guidance, breaking research, and unfortunately, misleading or false health claims. Your browser is both a window to reputable sources and a highway for misinformation. Firefox offers tools, settings, and extensions you can use to reduce exposure to false health claims and improve the quality of the content you see. This article explains practical, step-by-step ways to configure Firefox for safer, more reliable COVID-19 information.
Understand the problem: why browsers matter
Browsers shape what you see. Search results, news feeds, social media embeds, and suggestion engines all influence the content that reaches you. Misinformation spreads quickly because it’s often sensational, appears authoritative, and is shared widely. By configuring Firefox to prioritize privacy, block trackers, and surface trustworthy sources, you can dramatically reduce the chance of encountering false health claims.
1) Start with Firefox’s built-in protections
Firefox includes several privacy and security features activated by default or easy to enable:
- Enhanced Tracking Protection (ETP): Blocks known trackers that collect browsing data used to personalize and amplify misleading content. In Firefox’s address bar, click the shield icon to confirm ETP is on. Set it to “Strict” for stronger protection (note: this can break some site features).
- Block deceptive content and dangerous downloads: Firefox warns about fraudulent websites and blocks known malicious downloads. Keep these protections enabled in Settings > Privacy & Security.
- HTTPS-Only Mode: Forces secure connections, reducing the risk of man-in-the-middle attacks that could serve altered content. Enable in Settings > Privacy & Security > HTTPS-Only Mode.
Keep Firefox updated: new versions include security and anti-tracking improvements. Enable automatic updates in About Firefox or Settings.
2) Tame search results and news feeds
Search engines and social platforms are primary vectors for misinformation. You can change or filter how results appear:
- Use more reliable search engines as default. Consider switching from engines that heavily personalize results to ones with stronger anti-personalization and quality filters.
- Disable or limit personalized suggestions: In Firefox Settings, turn off “Search suggestions” if you find autocomplete amplifies sensational queries.
- Adjust news feed settings on sites you use (e.g., Twitter/X, Facebook, Reddit) to prioritize trusted sources, turn off algorithmic recommendations where possible, or follow verified public health accounts (WHO, CDC, local health departments).
3) Install extensions that reduce misinformation
Extensions can help block sensational content, highlight reliable sources, and warn about dubious claims. Only install from trusted developers and review permissions.
Recommended extension types:
- Fact-checking and verification tools — extensions that quickly search claim databases or fact-check sites for a highlighted statement.
- Content filters — tools that hide or downrank posts containing keywords associated with misinformation.
- Reader modes and content cleaners — simplify pages to show only article text and citations, reducing distracting sidebar feeds and embedded content.
Examples (search and install from Mozilla Add-ons):
- Extensions that provide link previews or source ratings.
- Script-blockers like uBlock Origin (used responsibly) to prevent third-party content injection.
- Reader View and readability extensions to focus on article content and sources.
Be cautious: no extension is perfect. Periodically audit installed extensions for trustworthiness and updates.
4) Use lists and blocking to control social media embeds
Social embeds (tweets, Facebook posts, YouTube videos) can inject misinformation into otherwise reputable pages. Control them by:
- Blocking third-party social media scripts using content blockers or extensions (e.g., uBlock Origin filters).
- Using content policies in extensions to selectively allow embeds from specific accounts or domains.
- Enabling Firefox’s Enhanced Tracking Protection to restrict social trackers that load embedded content.
This reduces the chance that a page displays an inaccurate viral post from a dubious source.
5) Vet sources quickly — build a mental checklist
When you encounter a COVID-19 claim, run a short vetting routine before trusting or sharing:
- Source: Is the content from a known health authority (WHO, CDC, NHS, local public health) or a reputable news outlet?
- Evidence: Does the article cite peer-reviewed studies, official guidance, or named experts? Beware anonymous claims and uncited statistics.
- Date: Is the information current? Guidance changes as knowledge evolves.
- Tone: Is it sensational or fear-inducing? Credible sources typically use measured language and state uncertainty.
- Confirmation: Search for the same claim on multiple reputable sources.
Consider bookmarking or keeping a short list of trusted local and international health sources for quick reference.
6) Configure content and privacy settings for safer browsing
Walk through these Firefox settings adjustments:
- Settings > Privacy & Security > Enhanced Tracking Protection: set to Strict (or Custom to block social trackers and cross-site cookies).
- Settings > Privacy & Security > Cookies and Site Data: block third-party cookies to limit cross-site tracking.
- Settings > Privacy & Security > Permissions: manage which sites can show notifications, access camera/microphone, or send pop-ups—deny or prompt for everything nonessential.
- Settings > Search: choose a less personalized search engine and disable “Search suggestions” if desired.
- Settings > General > Files and Applications: review what Firefox does with downloaded files; disable automatic opening of potentially risky file types.
7) Use Reader View and text-only reading to focus on content
Reader View strips away ads, sidebars, and embedded widgets that often carry misinformation. For articles, click the Reader View icon (page icon in address bar) or press F9. Reader View keeps main text and citations, which helps you assess claims without distraction.
8) Teach Firefox to help (user-side labeling and filtering)
If you manage a family or work devices, use these approaches:
- Use profile-specific extensions and content filters for kids or less tech-savvy users.
- Create curated bookmarks/favorites list of verified health resources and set the browser homepage to one of those sites.
- Use container tabs (Firefox Multi-Account Containers) to separate social accounts and reduce cross-site tracking that fuels personalized misinformation.
9) Be mindful when installing add-ons and themes
Only install add-ons from Mozilla Add-ons (addons.mozilla.org). Check:
- Developer reputation and reviews.
- Required permissions (avoid broad access unless necessary).
- Update frequency and support.
Remove any add-on that requests unexpected capabilities or shows intrusive behavior.
10) Advanced measures for power users
- Use uBlock Origin with custom filters that block known misinformation domains or social widgets.
- Employ privacy-focused hosts files or DNS-based blocking (e.g., Pi-hole) at the network level to block tracking and known misinformation sites.
- Combine Firefox with privacy-respecting VPNs or DNS-over-HTTPS to prevent ISP-level injections or manipulation.
Responding to misinformation you find
- Don’t amplify: avoid sharing or reposting sensational claims to “debunk” them unless you add clear context and link to reputable refutations.
- Report: Many platforms offer reporting tools for false health information. Use them on social platforms to flag content.
- Correct gently: If you must respond, link to primary sources (public health sites, peer-reviewed studies) rather than opinion pieces.
Final checklist (quick actions)
- Enable Enhanced Tracking Protection (Strict).
- Set search engine and disable search suggestions.
- Install vetted extensions: uBlock Origin, a fact-check helper, and a reader-mode enhancer.
- Block third-party cookies and social tracker scripts.
- Use Reader View and Multi-Account Containers for separation.
- Keep Firefox and extensions updated.
Reducing exposure to false health claims is a mix of technical configuration and informed habits. Firefox gives you strong tools—use them to prioritize authoritative sources, limit tracking and embedded social content, and make quick vetting second nature. The web will still contain misleading material, but with these settings you’ll see less of it and be better prepared to evaluate what you do encounter.
