Inicie no Modo de Segurança: O Firefox possui um "Modo de Segurança" que desativa temporariamente todas as extensões e usa as configurações padrão. Isso pode ajudar a determinar se o problema é causado por uma extensão ou configuração específica. Reinicie o Firefox: Às vezes, simplesmente fechar e reabrir o Firefox pode resolver problemas temporários.

2 Clear cache and cookies

Another common solution for resolving Firefox issues is to clear the cache and cookies. The cache is a temporary storage of web pages and files that Firefox uses to load them faster. Cookies are small pieces of data that websites store on your browser to remember your preferences and settings. However, sometimes the cache and cookies can become corrupted or outdated, causing errors, slow loading, or login issues. To clear the cache and cookies, click on the menu button, then select Options > Privacy & Security. Under Cookies and Site Data, click on Clear Data. Check the boxes for Cached Web Content and Cookies and Site Data, then click on Clear.
