What OS? What version of Firefox? Show the issue.

Did you try with Firefox in Troubleshoot Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

Did you clear your browser cache? https://support.mozilla.org/en-US/kb/clear-cookies-and-site-data-firefox

I have the same issue. Fully up to date Firefox with NO extensions activated. It was like this upon my very first Google Maps search and every one in sequence afterward. Yes, cookies and cache cleared, no extensions, stock install.

Can you advise on a fix?
