{note}Translation in progress.{/note} Alguns dos problemas que os utilizadores têm no Firefox podem ser causados por extras ou temas instalados. Este artigo descreve como determinar se o problema no Firefox é causado por um extra ou tema, e caso seja, como fazer com que o Firefox volte a funcionar normalmente. __TOC__ = Determinar se um extra ou tema é o problema = Em [[Modo de Segurança]], todos os extras ficam temporariamente inactivos e será utilizado o tema por defeito. Deste modo será mais fácil determinar se é um extra que está a causar o seu problema. [[T:safemode]] Quando a janela do Modo de Segurança for apresentado, clique o botão {button Continuar em Modo de Segurança}. Se o problema persistir em Modo de Segurança, o seu problema não está a ser causado por um extra ou tema. Se o problema não estiver presente em Modo de Segurança: * Um dos ficheiros de configuração do Firefox pode estar corrompido. [[A Caixa de Ferramentas está a reiniciar#Método 1: Em Modo de Segurança|Reinicie as suas caixas de ferramentas e controlos]] de modo a verificar se resolve o problema. * O tema que está a utilizar ou um dos extras pode estar a causar o problema. Continue neste artigo para resolver o problema. If you have been using a new theme, switch to the default theme and restart Firefox to see if the theme was causing the problem. # Click on the {menu Tools} menu, and select {menu Add-ons}. The Add-ons window will appear. # In the Add-ons window, click the {menu Themes} icon. # Select the default theme, then click the {button Use Theme} button, to make Firefox switch to that theme. # Close Firefox, then start it up again. When Firefox restarts, the default theme is in use. If the problem goes away, your theme was causing the problem. = Updating your themes = If an installed theme was causing the problem, it may have an update available that will fix it. # Click on the {menu Tools} menu and then choose {menu Add-ons}. The Add-ons dialog appears. # Click the {menu Themes} panel, which displays the list of installed themes. # To check for updates for installed themes, click {button Find Updates}. # If updates are found, install them by clicking {button Install Updates}. # When the installation is complete, click {button Restart Firefox}. # After Firefox restarts, your themes should have been updated. = Updating your extensions = If the problem persists with the default theme in use, you need to troubleshoot your extensions. If an extension is causing the problem may have an update available that will fix it. # Click the {menu Tools} menu and then choose {menu Add-ons}. The Add-ons dialog appears. # Click the {menu Extensions} panel, which displays the list of installed extensions. # To check for updates to each installed extension, click {button Find Updates}. # If updates are found, install them by clicking {button Install Updates}. # When the installation is complete, click {button Restart Firefox}. # After Firefox restarts, your extensions should have been updated. = Disabling faulty extensions = If there were no updates or if the problem didn't go away after the update, you can individually disable extensions. You won't lose any settings when you disable extensions, and you can re-enable them later. # Click the {menu Tools} menu and then select {menu Add-ons}. The Add-ons dialog appears. # Click the {menu Extensions} panel. The list of installed extensions is displayed. # Click the name of the extension you wish to disable. # To disable the selected extension, click {button Disable}. # [[T:closeFirefox]] # Restart Firefox. Now that the extension you chose has been disabled, your problem may be gone. ** If the problem persists, you should repeat the above process with each extension. When your problem goes away, the extension that you most recently disabled is the source of the issue. You can then re-enable all the other extensions. You can also look for help from the extension's author by asking him a question on [https://addons.mozilla.org addons.mozilla.org]. ;:{note}'''Note: Do not re-enable any extensions until you have found the extension causing the problem.'''{/note} == If you have a large number of extensions == If you have a large number of extensions installed then disabling them one by one may take a significant length of time. Disable one half of your extensions to see if the problem still exists: * If it does, then you know the problem exists in the second half, so you disable half of the remaining enabled extensions, and test again. * If it doesn't, then you know the problem exists in the first half, so you re-enable half of the extensions we just disabled and test again. By recursively enabling or disabling extensions in this manner you can home in on a misbehaving extension quicker than disabling them one by one.
