1. Objective

This procedure explains how to maintain a web browser properly so that websites open correctly, updated content is displayed, and login or script-related issues are reduced.

Main maintenance actions

Clear cached images and files
Remove site-specific cookies when necessary
Check extension conflicts
Refresh DNS/network data if needed
Restart browser after maintenance

2. Common Symptoms Indicating Browser Cleaning is Needed

Website works in Guest Mode / Incognito but not in normal mode
Page shows old content even after update
Login page loops or fails repeatedly
Buttons do not respond correctly
Blank or partially loaded page appears
Site opens in one browser but not in another
JavaScript tools or dashboards fail unexpectedly

3. SOP for Google Chrome / Microsoft Edge

Step 1: Hard Refresh the Website

Open the website page.
Press Ctrl + F5 on Windows.
This forces the browser to reload the latest files from the server.

Step 2: Clear Cached Images and Files

Open browser menu (three dots).
Go to Settings → Privacy and Security → Clear Browsing Data.
Select time range as All Time if the issue is persistent.
Tick Cached images and files.
Click Clear Data.

Step 3: Clear Cookies for One Specific Website

Go to Settings → Privacy and Security → Cookies and other site data.
Open See all site data and permissions.
Search the domain name, such as saitechinfo.com or saitechlabs.com.
Delete only the relevant site data.
Close and reopen the website.

Step 4: Disable Extensions Temporarily

Type chrome://extensions/ in Chrome or edge://extensions/ in Edge.
Disable ad blockers, script blockers, popup blockers, or security extensions one by one.
Reload the website after each test.
If the site works, identify the conflicting extension.

Step 5: Restart the Browser

Close all browser windows fully.
Reopen the browser.
Load the website again.

Note: If the website works in Guest Mode but not in normal mode, cookies, cache, or extensions are the most likely cause.

4. SOP for Mozilla Firefox

Open Menu → Settings → Privacy & Security.
Under Cookies and Site Data, click Clear Data.
Select Cached Web Content and, if needed, Cookies and Site Data.
Click Clear.
Restart Firefox and test the website again.

5. DNS and Network Cache Cleaning

This step is useful if the browser still shows a wrong or outdated connection path.

Windows DNS Flush Procedure

Open Command Prompt as Administrator.
Run the following command:

ipconfig /flushdns

Wait for the confirmation message.
Restart browser and test again.

6. Preventive Browser Maintenance Schedule

Activity	Recommended Frequency	Remarks
Hard refresh important dashboards	Whenever page update is expected	Useful after website code or JSON updates
Clear cached images and files	Once per week	Improves performance and reduces stale content issues
Delete site-specific cookies	Only when login/session issue occurs	Avoid deleting all cookies unless necessary
Check browser extensions	Once per month	Disable unused or suspicious extensions
Flush DNS	Only when connection mismatch occurs	Useful after server migration or DNS change
Restart browser/computer	As needed	Helps release temporary memory load

7. Troubleshooting Guide

Case 1: Site works in Incognito but not in normal mode

Likely cause: cache, cookies, or extension issue.

Case 2: Login fails repeatedly

Likely cause: corrupted cookies or expired session data.

Case 3: New website update is not visible

Likely cause: old cached CSS, JS, or image files.

Case 4: Certain buttons do not respond

Likely cause: blocked JavaScript due to extension or corrupted cached files.

Warning: Do not clear saved passwords unless required. While cleaning browsing data, carefully select only the necessary items.

8. Good Browser Usage Practices

Keep browser updated to the latest stable version
Avoid installing too many extensions
Use trusted antivirus and security settings
Restart browser daily if many tabs are used
Use Guest Mode to test whether issue is browser-profile related
For website admin work, use one dedicated browser profile if possible

9. Record of Maintenance

Date	Browser	Action Taken	Issue Observed	Status
____________	____________	____________	____________	____________
____________	____________	____________	____________	____________

10. Conclusion

Proper browser maintenance is a simple but powerful preventive action. In many cases, website opening problems are not due to the server but due to local browser cache, cookies, extensions, or temporary memory issues. Following this SOP helps users maintain stable browsing performance and smooth website operation.
