Home screen does not change. As much as I modify my preference for the home screen back to be an unwanted page.
não consigo alterar a página inicial. Já tentei tudo que recomendam. a tela inicial sempre volta para outro endereço.

if your manual changes don't 'stick' after a restart of the browser, please look out for any suspicious extensions (like 3rd-party-toolbars or things you have not installed intentionally) presently installed under firefox/tools > addons > extensions or the programs section of the windows control panel and remove those entries.
in case this doesn't solve the issue please try this: go to firefox > help > troubleshooting information > profile folder - "show folder", then a new window will open up. in this window look out for a file named user.js (it might be used to overwrite your custom settings). in case it is present, delete or rename this file and restart firefox afterwards.
Remove a toolbar that has taken over your Firefox search or home page
What is your home page?
Try to reset some preferences to the default with the SearchReset extension:
Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).
If there is a problem with searching via the default about:home page then try to reset the search engine used on the about:home page.
Reset the browser.startup.homepage_override.mstone pref via the right-click context menu to the default on the about:config page and close and restart Firefox to restore the about:home page to its default.
- Open the about:config page via the location bar
- Type in the Filter bar: mstone
- Right-click the browser.startup.homepage_override.mstone line and select: Reset
- Close and restart Firefox
If this didn't help then delete the delete the chromeappsstore.sqlite file in the Firefox Profile Folder and repeat the above.
