==Force Firefox to remember passwords==
How to force Firefox to remember passwords, despite the site's indication to not allow that:
* http://www.werockyourweb.com/force-firefox-save-password (older versions of Firefox)
The file we want to edit has changed, renamed from '''omni.jar''' to '''omni.ja''' and compressed differently, read this:
* https://developer.mozilla.org/en-US/docs/Mozilla/About_omni.ja_%28formerly_omni.jar%29
1. Unzip and ignore warnings:
<syntaxhighlight lang=bash>
locate omni.ja
cp /usr/lib/firefox/omni.ja $HOME/tmp
cd $HOME/tmp
unzip omni.ja -d ./omni
cd omni
gedit components/nsLoginManager.js
</syntaxhighlight>
2. Two lines of the file '''nsLoginManager.js''' in the archive '''omni.ja''' are commented to make function '''_isAutoCompleteDisabled''' always return false:
<syntaxhighlight lang=javascript>
    /* _isAutoCompleteDisabled
    * Returns true if the page requests autocomplete be disabled for the specified form input. */
    _isAutoCompleteDisabled : function (element) {
        //20130727: wjv: commented this part to always return false
        //if ( element && element.hasAttribute("autocomplete") && element.getAttribute("autocomplete").toLowerCase() == "off")
        //  return true;
    return false;
    },
</syntaxhighlight>
3. Re-create '''omni.ja'''. '''Make sure you maintain a copy of the original''':
<syntaxhighlight lang=bash>
zip -r ../omni.ja
mv /usr/lib/firefox/omni.ja /usr/lib/firefox/omni.ja_original
cd ..
cp omni.ja /usr/lib/firefox/omni.ja
</syntaxhighlight>
4. Restart Firefox.

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.

Disable translation dialog 'Translate this page?'

  1. Enter about:config into the address bar
  2. Search for the preference named browser.translations.automaticallyPopup
  3. Change its value to false.

Force pop-ups in a new Tab

https://support.mozilla.org/en-US/questions/1066799

  1. Enter about:config into the address bar
  2. Search for the preference named browser.link.open_newwindow.restriction
  3. Change its value to 0.

Don't close browser with last tab

  1. Go to URL: about:config
  2. Search for the preference named browser.tabs.closeWindowWithLastTab
  3. Change its value to false.

Firefox disable website notifications

  1. Go to url: about:preferences (settings)
  2. Search 'notifications'
  3. Look for 'Permissions' and sub-item 'Notifications'
  4. Click Settings
  5. Check 'block new requests ~'

Firefox force new tabs to load in background

  1. Go to URL: about:config
  2. Search for the preference named browser.tabs.loadDivertedInBackground
  3. Change its value to true.

Firefox disable quick find

Shortcut "/" brings up "Quick find" which can be quite annoying if you want tu use this character.

  1. Go to URL: about:config
  2. Search for the preference named accessibility.typeaheadfind
  3. Search for the preference named accessibility.typeaheadfind.autostart
  4. Search for the preference named accessibility.typeaheadfind.manual
  5. Change all these values to false.

Firefox on-video picture-in-picture button

If you hover over the video, the picture-in-picture button becomes visible. This, however, is suppressed for short videos. I found that streaming videos need to run for the duration before the button becomes available. You can lower this value here.

  1. Go to URL: about:config
  2. Search for the preference named media.videocontrols.picture-in-picture.video-toggle.min-video-secs
  3. default value is 45, lower this to for example 1

Usage

Find bookmark in folder structure

  1. Open the website the bookmark points to
  2. Click the bookmark star-icon in the address-bar
  3. In the dialog you can see where the bookmark is located

Block functionality

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>

Context Search Menu

Context Search expands the context menu's 'Search for' item into a list of installed search engines, allowing you to choose the engine you want to use for each search.

Development
