Esta não é exatamente uma pergunta, mas um relato para talvez servir de pista para o problema em si.

Fiz o upgrade do windows 7 para o windows 8 com a opção de manter os programas e dados. Após o upgrade o Firefox passou a apresentar um alto consumo de CPU, apenas abrindo o mesmo, sem navegar e tendo a pagina de busca do google como padrão. Mesmo abrindo o Firefox com todas os puglins desabilitados o alto consumo permanece ao executar o firefox, sem nenhuma navegação.

Desde o FF 17, baixo as atualizações mas continua acontecendo o problema (até pelo menos o FF 19)

Fazendo o "Reset Firefox to its default state" da pagina about:support, funcionou uma vez, mas logo voltou a acontecer o problema

Recentemente vi o artigo https://support.mozilla.org/pt-BR/kb/Firefox%20est%C3%A1%20rodando%20mas%20n%C3%A3o%20est%C3%A1%20respondendo

Então resolvi excluir o diretório do profile e magicamente o FF voltou ao normal. Tudo muito bom, mas ai tive que reiniciar o computador por um motivo qualquer e ao abrir o FF, ele novamente apresentou o problema de consumo de CPU. Então percebi que se apagar o profile, ele cria um novo e funciona normalmente , posso abrir e fechar o FF quantas vezes quiser e o problema do consumo não ocorre. Basta reiniciar o computador e o problema volta. Então creio que existe algum problema que ocorre com o profile. Fiz o procedimento varias vezes, não instalei nenhum plugin extra e somente abrindo e fechando o FF na sua pagina default e sempre que se reinicia o computador, o problema volta.

Por ora, infelizmente resolvi meu problema trocando de navegador e como o Thunderbird estava apresentando o mesmo problema de alto consumo de CPU tive que abandonar os softwares da Mozilla mesmo gostando muito deles.

Which security software (firewall, anti-virus) do you have?

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

Answer

lkmatsumura,
Sorry you are having problems.

So in summary you seem to have problems with both Firefox & Thunderbird but that is temporarily solved with a new profile, but returns once the computer is restarted.

I do not know what is causing that but my first thought is do you have any security or recovery software that is resetting firefox, or modifying the profile.

If you do consider using Firefox again as a first step back up your profile

The next steps will be troubleshooting the problem, and probably doing a clean install. If necessary I can provide further instructions.

Incidentally Firefox has a known crashing problem currently if Firefox 19 is used on some AMD PCs using Windows 8.

Q ? (I used Google translate )

This is not exactly a question, but maybe a story to serve as a clue to the problem itself.

I upgrade windows 7 to windows 8 with the option to keep the programs and data. After upgrading Firefox now provides a high CPU consumption, just by opening it, without having to browse and search page of google as default. Even opening Firefox with all the puglins high consumption remains disabled when running firefox with no navigation.

Since FF 17, down updates but the problem keeps happening (at least until the FF 19)

Making the "Reset Firefox to its default state" of the page about: support, it worked once, but then it happened again the problem

I recently saw the article

So I decided to delete the profile directory and magically the FF returned to normal. All very good, but then had to restart the computer for some reason and when you open the FF, he again presented the problem of CPU consumption. Then I realized that if I delete the profile, it creates a new and works normally, I can open and close the FF number of times and consumption problem does not occur. Just restart the computer and the problem returns. So I think there is some problem in the profile. I did the procedure several times, did not install any extra plug-and only by opening and closing the FF in your default page and whenever you restart the computer, the problem returns.

For now, unfortunately solved my problem by changing the browser and the Thunderbird was presenting as the same problem of high CPU consumption had to abandon the Mozilla software even really enjoying them.

Hi, thanks for reply I´m using avast 7 free antivirus version.

I tried uninstall and then reinstall Firefox but the problem of high CPU consumption remains. To do a clean install, I should do some extra step?

It seems odd that a fresh install works until you restart. Presumably something running when you restart is causing this. I was hoping it may be some form of recovery software or fancy security software that resets Firefox to a prior state. (I guess it could be a malware problem).

Did you try cor-el's suggestion of an F8 Windows reboot, does that restart ok after a reinstall of Firefox and have ordinary CPU use levels.

To do a clean install, I should do some extra step? 

Yes, the Firefox program folder is removed
