What to Do If the Tabs UI Feels Slow
Last updated: June 18, 2026
Overview
If you notice that the Tabs UI feels slow, unresponsive, or takes longer than expected to load or switch between tabs, there are several steps you can take to help identify and resolve the issue.
"Slow" can mean different things, including:
Tabs taking a long time to load
Lag when scrolling or interacting with content
Content appearing blank before loading
Browser freezing or becoming unresponsive
The steps below can help determine whether the issue is related to your browser, network, device performance, or a temporary service issue.
Step 1: Refresh the Page
Start with a simple browser refresh.
Windows: Ctrl + F5 or Ctrl + Shift + R
Mac: Cmd + Shift + R
A hard refresh clears cached page resources and reloads the latest version of the application.
Step 2: Check Your Network Connection
A slow or unstable internet connection can impact Tabs performance.
Verify that:
Other websites load normally
You are not experiencing VPN or proxy connectivity issues
Your network is not experiencing high latency or packet loss
If possible, test on a different network to determine whether the issue is network-related.
Step 3: Close Unnecessary Browser Tabs and Applications
Running many browser tabs or resource-intensive applications can affect performance.
Consider:
Closing unused browser tabs
Closing applications that consume significant CPU or memory
Restarting your browser
Step 4: Try an Incognito or Private Browser Window
Browser extensions can sometimes interfere with application performance.
Open the Tabs UI in:
Chrome Incognito Mode
Edge InPrivate Mode
Firefox Private Window
If performance improves, a browser extension may be contributing to the issue.
Step 5: Clear Browser Cache
Outdated or corrupted cached files can occasionally affect performance.
Clear your browser's:
Cached images and files
Site data (if appropriate)
After clearing the cache, reload the Tabs UI and test again.
Step 6: Verify Browser Compatibility
For the best experience, use a supported and up-to-date browser version.
Recommended browsers include:
Google Chrome (latest version)
Microsoft Edge (latest version)
Mozilla Firefox (latest version)
Safari (latest version)
If you're using an older browser version, update it and test again.
Step 7: Test with a Different Browser or Device
Testing from another browser or device can help isolate the issue.
If the Tabs UI performs normally elsewhere, the problem may be specific to your original browser, device, or local configuration.
Step 8: Check for Large or Complex Workloads
Performance may be affected when:
Loading unusually large datasets
Displaying a high volume of records
Running multiple concurrent operations
If applicable, try reducing filters, narrowing the dataset, or limiting the amount of information displayed at one time.
Step 9: Capture Information for Support
