The browser is what you use to access Trello on your Mac or PC (and maybe your phone). This includes Edge, Chrome, Firefox, and Safari. Because all browsers are different, sometimes you might experience quirks in Trello because of the browser you are using. Those may include issues when logging in (such as blank pages or login loops), and unexpected behavior in Trello once you log in. This article will help you troubleshoot those quirks.
First, make sure you are using one of our supported browsers. We can't support every version of every browser, so it helps to make sure you're using one that's supported and tested by us.
Next, try logging into Trello in the following ways to see if you can reproduce the issue you are having:
Disable all extensions and customizations in your current browser
Use a private/incognito browsing tab
Try using a different browser on the same computer
Connect to a different network
Try using a different computer
Allow cookies from id.atlassian.com, auth.atlassian.com, and trello.com (read more about cookies on our Cookies and Tracking notice)
Allow cookies from third party sites in case you're running into any issues with linking to Google Drive or Dropbox
Troubleshooting your extensions
If you disabled your extensions and Trello started working normally again, one of your extensions is likely causing issues with Trello. You can now re-enable your extensions one by one until you find the problematic one.
If it's a privacy extension you want to keep using, such as DuckDuckGo, Ublock, or similar ones, try adding the following domains to your allow list:
Cookies are required for several functions to work properly on Trello. You might need to enable Cookies entirely, if they are currently disabled:
If Cookies are enabled on your browser, check if the following domains are allowed on your settings for specific websites: id.atlassian.com, auth.atlassian.com, and trello.com
You can read more about cookies on our Cookies and Tracking notice. The same process might be necessary for third-party sites if you're facing issues specific to those services (such as Google Drive or Dropbox)
Clearing your web browser's cache
If you can't get another browser to try, we'll need you to clear your cache and check for errors.
Console Log Errors
You can also check for errors in your browser's error console. You can copy any errors you see there, or take a screenshot and send it to us.
To bring up your browser's console:
Chrome: Command+Opt+J(Mac) or Ctrl+Shift+J (Windows)
Firefox: Commandd+Opt+K(Mac) or Ctrl+Shift+K(Windows)
Safari: Go to Preferences (Ctrl+,) and enable the "Develop" menu via the "Advanced" tab. Then, you can use this keyboard shortcut:Cmd+Option+C. As an alternative, you can right-click on the webpage and click "Inspect Element", and the developer window will appear. In the window that opens, click the "Console" tab.
Edge: F12 and go to the 'Console' tab.
This may seem like a lot to go through, but it will help us address your issue faster!
