Firefox Settings

This page some Firefox extensions that I use regularly. Click on the name to search for them on Mozilla's site.

Settings

Disable password pop-up

Using a password manager you might want to disable this dialog.

You can disable 'Ask to save passwords' in the settings. However, that would also disable this function for all sites.

I usually pick 'Never save' until I visited most password sites until it calms down a bit.

Firefox on-video picture-in-picture button

Search

Add right-click search engines

Make search functionality available in the Search Bar with Add to Search bar

The search engine's URL can be customized to your wishes. I made changes to IMDB search to jump to the best match immediately, instead of showing all possible matches. This trick uses Google's 'Im+Feeling+Lucky' function. First make sure you have the IMDB search engine and then modify it following beneath example.

gedit /home/$USER/.mozilla/firefox/*.default/searchplugins/imdb.xml

<SearchPlugin xmlns="http://www.mozilla.org/2006/browser/search/"
 xmlns:os="http://a9.com/-/spec/opensearch/1.1/">
  <os:ShortName>IMDb</os:ShortName>
  <os:Description>IMDb</os:Description>
  <os:InputEncoding>ISO-8859-1</os:InputEncoding>
  <os:Image width="16" height="16">data:image/png;base64,icon_image_data_here</os:Image>
  <SearchForm>http://www.google.com/search</SearchForm>
  <os:Url type="text/html" method="GET" template="http://www.google.com/search">
    <os:Param name="btnI" value="Im+Feeling+Lucky"/>
    <os:Param name="q" value="IMDB+{searchTerms}"/>
  </os:Url>
</SearchPlugin>
