Identify Your Browser Issue

Browser compatibility problems typically manifest in specific ways depending on which browser you’re using. Use this diagnostic table to identify your scenario:
BrowserCommon IssuesSeverity
FirefoxScrollbar rendering errors, export buttons non-functional⚠️ Medium
Internet ExplorerNot supported - upgrade required❌ Critical
Edge (Chromium)Recommended - best compatibility✅ Optimal
ChromeGenerally compatible, rare display issuesGood
SafariLimited testing, potential CSS inconsistencies❓ Unknown
Firefox users may experience incorrect scrollbar rendering in RISKSHEET grids. This is a known browser-specific limitation that cannot be resolved through configuration changes. Consider switching to Microsoft Edge for optimal compatibility.

​
Step 1: Check Browser Version

Verify you’re using a supported modern browser:
  1. Open your browser’s About or Help menu
  2. Check the version number
  3. Update to the latest version if outdated
  4. Clear browser cache after updating: Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac)
Microsoft Edge (Chromium-based) provides the best RISKSHEET experience. Download from microsoft.com/edge if not already installed.

​
Step 2: Diagnose Firefox Export Issues

If Excel or PDF export buttons don’t respond in Firefox:
  1. Open browser Developer Console: Press F12
  2. Navigate to the Console tab
  3. Click the export button and observe for JavaScript errors
  4. Look for messages containing “export” or “download”
  • Click Export button — is button unresponsive?
    • Check browser Developer Console (F12)
    • JavaScript error? — Browser extension conflict
    • CORS warning? — Polarion server configuration issue
    • No errors visible? — Known Firefox limitation; switch to Microsoft Edge

​
Step 3: Test in Microsoft Edge

To verify the issue is browser-specific:
  1. Open the same RISKSHEET document in Microsoft Edge
  2. Test the failing functionality (export, scrolling, rendering)
  3. If it works in Edge, the issue is browser-specific
  4. If it fails in Edge too, see Troubleshooting index for other causes

​
Step 4: Disable Browser Extensions

Browser extensions can interfere with RISKSHEET functionality:
  1. Open your browser’s Extensions or Add-ons manager
  2. Disable all extensions temporarily
  3. Restart the browser
  4. Test RISKSHEET again
  5. Re-enable extensions one at a time to identify the culprit
Extensions like uBlock Origin, NoScript, or Privacy Badger may block RISKSHEET functionality. Add your Polarion server to the whitelist if using these tools.

​
Step 5: Clear Browser Cache and Cookies

Stale cached resources can cause rendering issues: Edge/Chrome:
  1. Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac)
  2. Select Cached images and files and Cookies and other site data
  3. Set time range to All time
  4. Click Clear data
Firefox:
  1. Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac)
  2. Check Cookies and Cache
  3. Time range: Everything
  4. Click Clear Now

​
Step 6: Adjust Browser Zoom Level

Incorrect zoom levels can cause layout issues:
  1. Reset zoom to 100%: Press Ctrl+0 (Windows) or Cmd+0 (Mac)
  2. Reload the RISKSHEET page: F5 or Ctrl+R
  3. Check if rendering issues persist

​
Step 7: Enable JavaScript and Cookies

RISKSHEET requires JavaScript and cookies to function: Edge/Chrome:
  1. Navigate to Settings → Privacy, search, and services
  2. Under Cookies and site data, ensure Block third-party cookies is OFF for your Polarion domain
  3. Under JavaScript, ensure it’s Allowed
Firefox:
  1. Navigate to Settings → Privacy & Security
  2. Under Cookies and Site Data, choose Standard protection
  3. Scroll to Permissions → JavaScript and ensure it’s enabled

Common Browser-Specific Workarounds

​
Firefox Scrollbar Issues

  • Symptom: Scrollbars render incorrectly or flicker
  • Cause: Browser-specific CSS rendering
  • Solution: Switch to Microsoft Edge
  • Status: Known limitation, no configuration fix available

​
Export Button Not Working (Firefox)

  • Symptom: Excel/PDF export buttons are non-responsive
  • Cause: Firefox-specific event handling differences
  • Solution: Use Edge or Chrome for export operations
  • Workaround: Right-click export button and select “Open Link in New Tab” if available

​
Display Issues After Browser Update

  • Symptom: Layout broken after browser auto-update
  • Cause: Cached CSS and JavaScript from previous version
  • Solution: Clear cache completely (Step 5), then perform hard reload: Ctrl+Shift+R

​
Verification

After applying fixes, you should see:
  • RISKSHEET grid renders correctly with proper scrollbars
  • Export buttons respond when clicked
  • No JavaScript console errors
  • All columns and data display as expected
  • Interactive features (sorting, filtering, editing) work smoothly
If issues persist after switching browsers and clearing cache, the problem may not be browser-related. See the troubleshooting guides below for other potential causes.
