ByIt’s impossible to talk about online movie streaming without mentioning 123Movies. 123Movies allows users to watch the latest movies, web series, and shows for free. However, users sometimes face a common problem — “123Movies Full Screen Not Working,” meaning the website doesn’t open in full screen, or the video doesn’t go into full-screen mode.
This problem is caused by browser settings, site scripts, ad blockers, cache, cookies, video player glitches, and extension conflicts. This guide will explain why 122Movies full screen doesn’t work and how to fix it using 8 of the most effective methods.
123Movies Full Screen Not Working: Main Reasons
There are several technical reasons behind the full-screen issue on 123Movies. Some of the major problems include:
Outdated browser version
Corrupted site cookies and cache
Browser extensions interfering
Ad blocker enabled
Video player script blocked
VPN/Proxy issues
Missing video player permissions
Outdated graphics support in the system
1. Clear Browser Cache and Cookies (Most Effective Method)
Sometimes, the browser’s page cache and cookies get corrupted, causing the full-screen option to malfunction. To fix this:
How to Clear Cache in Chrome
Press `Ctrl + Shift + Delete`
Select All Time
Select Cookies & Cached Images
Click on Clear Data
Then reopen the website.
2. Disable Browser Extensions (Especially Ad Blockers)
Most free services on 123Movies rely on ads, so Ad Blockers can block the full-screen script.
To disable:
In Chrome:
Click the three dots at the top
Extensions
Turn off each extension
If the problem is resolved, then the extension is the culprit. 3. Check 123Movies in Incognito Mode
Incognito Mode runs without cache and extensions. To open it:
`Ctrl + Shift + N`
Then try playing the video to see if full-screen works.
If yes, it means the problem is with your browser extensions or stored cache.
4. Update Your Browser
Older browser versions don’t handle video player JavaScript correctly. To update:
Chrome → Settings → About Chrome → Update
Updates are also necessary if you are using Brave, Firefox, or Edge.
5. Allow Site Permissions in Browser Settings
Sometimes, permissions for the full-screen feature are blocked.
In Chrome:
Lock icon to the left of the URL
Site Settings
Full Screen → Allow
If it’s set to Block, full screen won’t work.
6. Disable VPN and Proxy
Many users use VPNs to access geo-restricted content. However, VPNs can block 123Movies scripts.
Disable → Restart your browser → Check again
If the website is opening with a VPN, try a different server.
7. Test on a Different Browser or Device
If 123Movies isn’t working in Chrome, try Firefox, Edge, or Brave.
On mobile:
Chrome → Full-screen icon
If it doesn’t work, enable Chrome’s Desktop Mode.
Sometimes, there might be a device-based compatibility issue.
8. Disable Ad-blocking or Security Software (PC Users)
Some security tools on PCs block scripts.
Windows Security
Avast
Kaspersky
AdGuard Desktop
Turn off the Web Shield or Script Blocking feature in these programs.
> Note: Don’t ignore security — re-enable it after watching the video.
