Travamento do Firefox
Quando um programa trava, ele não aceita mais nenhum comando do usuário e parece não estar executando nenhuma ação. Outros termos para travamento são "congelamento" ou "não respondendo".
- Um programa travado é diferente de um programa que tenha falhado; uma falha termina o programa.
- Um programa travado não responde às suas ações. Em outras situações, o Firefox responde ao seu menu e comandos, mas não consegue carregar os sites.
Para resolver problemas de travamento não especificamente mencionados neste artigo, ou se as soluções propostas não resolvem o problema, consulte Solução de problemas básicos. Você também deve verificar a existência de vírus, spyware e outros programas maliciosos no computador e ler O meu problema com o Firefox é resultado de um programa malicioso.

Hang after prolonged use
Firefox may hang if left open for long periods of time. To fix the issue, restart Firefox.
If you regularly leave Firefox open so that you return to where you left off, you may want to use Firefox's Session Restore feature. When you exit the program, Firefox can remember your open windows and tabs. When you restart Firefox, you can optionally reload those windows and tabs.

Firefox is now configured to remember your windows and tabs. You can close Firefox without losing the currently opened web pages, which may prevent Firefox from hanging.
Hang deleting bookmarks folder
Trying to delete a bookmarks folder that contains many bookmarks and multiple levels of sub-folders can cause Firefox to hang. To work around this problem, delete unwanted bookmark sub-folders in small steps. .
Hang at exit
Sometimes when you close Firefox, it may stop responding and remain in memory, even though no Firefox windows are open. This can prevent Firefox from working properly the next time you open it or you may see a "Close Firefox" dialog box with the message, Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.. You must then end all Firefox processes or restart the computer before you can reopen Firefox. (See Firefox está rodando mas não está respondendo for other causes and solutions.)
If Firefox processes that remain in memory at exit are a recurring problem, try these solutions:
- A problematic extension can cause the problem, which can be resolved by disabling or uninstalling the extension. For information on diagnosing and fixing problems caused by faulty extensions, see the Solução de problemas com extensões e temas article.
- Sometimes Java applets can cause the Firefox process to persist after exit. Try updating Java to the latest version or, if you don't need the Java plugin, you can disable it from the Plugins panel of the Firefox Add-ons window. For more information, see Usando o plugin Java com o Firefox.
- Using certain Internet security software is reported to cause the issue on some systems:
- If you use ZoneAlarm on Windows Vista, uninstall it and use another firewall product (or use the Windows Firewall).
- If you use Avast! Antivirus, switch to another antivirus product if you also have ZoneAlarm installed.
- If you use Norton 360 2.0, make sure that you have all available Norton updates (for more help, contact Norton Support) and that you have followed the instructions in the Configure Norton 360 to work with Firefox article.
- If you have upgraded Comodo Internet Security from a version prior to 3.10, the Comodo Safe Surf component from the previous version can cause Firefox to hang at exit. To resolve the issue, you can uninstall Comodo Safe Surf via Windows Control Panel, as its function is now integrated into the current Comodo application.
