How do I get rid of portaldosites.com? Their instructions don't work!
When I open a new tab, an ad for a gambling site takes extra long to load - I spend more time waiting than doing.
Their instructions are: Uninstall from Firefox Newtab 1 - Open Firefox explore. 2 - Click "Firefox" then click "Add-ons" in the left-top of the page. 3 - Click "Extensions" in the left of the new page. 4 - Click "Remove" button of "Lightning Speed Dial". 5 - Restart Firefox explore,newtab add-on has been removed.
The trouble is that "Lightning Speed Dial" doesn't appear in "Add-ons" list.

You have a browser.newtab.url pref that sets the new tab page to the www.dosearches.com website.
Your System Details List shows that you have a user.js file in the profile folder to initialize some prefs each time you start Firefox.
The user.js file is only present if you or other software has created it, so normally it wouldn't be there. You can check its content with a plain text editor if you didn't create this file yourself.
The user.js file is read each time you start Firefox and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.
Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.
You can use this button to go to the Firefox profile folder:
- Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
