iOS: How to fix/change Voicemail number

Recently, a friends voice mail “button” did not work anymore. Upon calling the voice mail, an audio error message appeared saying that the voice mail is not available or cannot be reached (something like that).

Unfortunately, Apple does not want you to just change the associated voice mail phone number that is called when tapping on “Voicemail”.

Fortunately, there is a shortcut:

  1. Go to the phone’s keypad
  2. Dial *#5005*86# and “call it”
  3. A phone number will appear, which is the one currently associated with the voice mail.  Write this down just in case.
  4. Now, call *5005*86*<insertPhoneNumber># and replace the placeholder with your phone number, starting with the country code (1 in this case for North America). For example, 14381234567.
  5. The voice mail button should now work.

This approach worked on the TELUS network (using Koodo). If it doesn’t work for you, revert the phone number to the one written down in step 3 and contact your provider.

Firefox close tab button on hover

There are probably extensions that allow to do that, however, this is not necessary as I will show in this post. Maybe you’ve seen the functionality in Safari or just wondered why the close button for tabs in Firefox can’t just always be there. In Safari, the close button appears when hovering over the tab itself.

The following modification adds this functionality to Firefox. You need to create a file called userChrome.css with the following content:

.tabbrowser-tab:not([selected]) .tab-close-button {
        visibility: hidden !important;
        margin-left: -16px !important;
}

.tabbrowser-tab:not([selected]):hover .tab-close-button {
        visibility: visible !important; 
        margin-left: 0px !important;
}

Place this file into the chrome folder inside your profile’s directory. Follow the directions from Mozilla to find out where to find the profile’s directory location.

Update: It just tried this again myself due to a fresh installation and you also need to change the browser.tabs.tabClipWidth preference from it’s default value (140) to 99.

Then just restart Firefox and you are done.
