Greetings! Wallacejc,

To disable the pop-up blocker simply follow the below steps:

• Open the Tools menu at the top right of your browser.
• Click Options.
• Click the Content tab.
• Next to Block pop-up windows, click Exceptions.
• Type www.wix.com and click Allow.
• Click Close.
• Click OK.

Note: If you see the pop up when logging in your editor, simply click on Options.

Note that on Mac it is Firefox -> Preferences.

Are you sure this is about a pop-up blocker?

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (e.g. Adblock Plus, NoScript, Ghostery, uBlock Origin) always make sure such extensions do not block (wanted) content.

• make sure your extensions and filters are updated to the latest version

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
• do NOT click the "Refresh Firefox" button on the Safe Mode start window
