Firebug 2 doesn’t work in multi-process browsers (i.e. e10s) and converting it is too complex, so it will stop working when e10s is activated in Firefox. You will be able to disable e10s for a while to keep using Firebug 2, but this won’t last forever. [[https://hacks.mozilla.org/2017/10/saying-goodbye-to-firebug/|Say Goodbye to Firebug]]...

=== [[superuser>1096974|How to force multiprocess mode in FF v53?]] ===

<note tip>
By default [[https://developer.mozilla.org/en-US/Add-ons/Install_Manifests#multiprocessCompatible|FF v51-53 checks]] that no plugin declares ''<em:multiprocessCompatible>false</em:multiprocessCompatible>'' in its manifest. To disable this check set ''extensions.e10sBlockedByAddons=false'' and verify on ''about:support'' that //Multiprocess Windows// is //1/1 (Enabled by default)// or //1/1 (Enabled by user)// (and not //0/1 (Disabled by add-ons)//).

See additionally on multiprocess mode:

</note>


=== [[http://cdivilly.wordpress.com/2013/08/15/disable-firefox-redirecting-to-localhost-com/|Disable Firefox redirecting to localhost.com]] ===

<note tip>
To disable Firefox redirection to ''www.localhost.com'' when one types ''lcoalhost'' set ''browser.fixup.alternate.enabled=false''
</note>


=== Increase JavaScript execution time ===

<note tip>
  * ''dom.max_script_run_time=30''
</note>


=== How to enable spellcheck for all input fields? ===

<note tip>
Change the setting for ''layout.spellcheckDefault'' from 0 to 1 to enable spell checking in all ''<textarea>'' fields, or make the value 2 to enable spell checking in all text input fields.
  * ''layout.spellcheckDefault=2''
</note>


=== "The page is not redirecting properly" error ===

<note tip>
As from [[mozillazine>The_page_is_not_redirecting_properly|The page is not redirecting properly]] just remove cookies associated with failing domain.
</note>


=== After the update to FF v22 everything is zoomed in ===

<note tip>
  * From [[http://support.mozilla.org/en-US/questions/959762|After the update everything is zoomed in. How do I revert this?]]: \\
    Set the value of ''layout.css.devPixelsPerPx'' preference to value e.g. ''1.2''.
  * From [[https://support.mozilla.org/en-US/kb/font-size-and-zoom-increase-size-of-web-pages|Control the zoom for all web pages at once]]:\\
    Install [[https://addons.mozilla.org/en-US/firefox/addon/nosquint/|NoSquint]]
</note>


=== [[https://support.mozilla.org/en-US/questions/951495#answer-458397|How to disable plugin check]] ===

<note tip>
Set:
  * ''%%plugins.update.url=""%%''
  * ''plugins.hide_infobar_for_outdated_plugin=true''
  * Create new ''boolean'' variable ''extensions.checkCompatibility.17.0=false'' (use your current FF version number)
</note>


=== [[https://support.mozilla.org/en-US/questions/1166173|How do I email a link of the current page?]] ===

<note tip>
There are two options:

  * ''File -> Email Link...''
  * ''Customize'' toolbar and add ''Email a link to this page'' button to it.
</note>


=== ABN AMRO e.identifier plugin does not work with FF v22 ===

<note tip>
This is true: plugin does not work for latest versions of FF. See [[https://support.mozilla.org/en-US/questions/966723|ABNAMRO Indentifier don't operate with the last version of Firefox]] and  [[https://support.mozilla.org/en-US/questions/964083|Sinds ik de nieuwste update heb geinstalleerd, werkt de ABN AMRO e.dentifier2 plug-in 0.1.0.4 niet meer]].

Updates:
  * FF v33 works fine.
  * //2017-05-20//: ''readme.txt'' for plugin v3.10 from June 2016 reads that it supports Firefox v45 and higher, but note that Firefox v52 ESR ×32 is the [[https://support.mozilla.org/en-US/kb/npapi-plugins|last Firefox that supports NPAPI plugins]].
</note>


=== [[https://support.mozilla.org/en-US/questions/966369|Firefox does not play sound in any HTML5 player]] ===

<note tip>
The simplest is to [[https://www.youtube.com/html5|switch off HTML5 in YouTube]] and play via Flash.
</note>


=== How to enable SSO in Firefox? ===

<note tip>
Set:
  * ''%%network.negotiate-auth.trusted-uris=http://, https://%%''
  * ''%%network.negotiate-auth.delegation-uris=http://,https://%%''

On Windows this setting should be enough to use your [[wp>Active Directory|AD]] credentials. On Linux you need to have valid Kerberos ticket, which can be obtained using the command ''kinit -pkt /path/to/file.keytab id@domain.org'' (see ''man kinit'').

=== How to disable SSLv3 in FF? ===

<note tip>
Set ''security.tls.version.min=1''.

=== If Firefox has crashed and session was not restored, how to recover it? ===

<note tip>
  * Make a copy of ''sessionstore-backups'' directory (if something goes wrong with recovery, you can always retry).
  * Close Firefox.
  * Copy ''sessionstore-backups\recovery.bak'' to Firefox profile directory with a name ''sessionstore.js'' (FF 45.0.1) or ''sessionrestore.js'' (older FF versions).
  * Start Firefox.

<note>
Firefox v53-56 fails to correctly convert sessions to new JSONLZ4 format. Before upgrading:

  * Backup ''sessionstore-backups'' folder.
  * Install Firefox, start Firefox, close Firefox.
  * Copy ''sessionstore-backups\recovery.bak'' (or ''sessionstore-backups\recovery.js'' -- check which one has more recent modification date) from backup made on step 1 to ''sessionstore.js''.
  * Remove ''sessionstore-backups\recovery.*'', ''sessionstore-backups\previous.jsonlz4'' and ''sessionrestore.jsonlz4''.
  * Start Firefox.

See [[https://support.mozilla.org/en-US/questions/1173678|Convert sessionstore.js to sessionstore.jsonlz4]] for more details.

Use [[https://www.jeffersonscher.com/res/scrounger.html|Scrounger]] to extract links from plain JS or JSONLZ4 format and overwrite ''sessionstore.js'' after stopping Firefox, check [[https://support.mozilla.org/en-US/questions/1189759#answer-1068259|Firefox restore a previous session]].

=== [[superuser>945887|Rewrite browsing history and sessions after website changes domain]] ===

<note tip>
SQL script to execute over ''places.sqlite'':
<code sql>
.open places.sqlite
delete from moz_places where instr(url,'broken.com') > 0;
update moz_places set url = replace(url,'my.com','my.org');
update moz_places set url = replace(url,'my.edu','my.org');
</code>
CMD script to apply changes to Firefox places (path to profile should be corrected correspondingly):
<code cmd>
set PROFILE=%APPDATA%\Mozilla\Firefox\Profiles\default
copy %PROFILE%\places.sqlite places.sqlite
copy places.sqlite places.sqlite.orig
sqlite3.exe < places.sql
move places.sqlite %PROFILE%\places.sqlite
</code>
''sqlite3.exe'' can be downloaded from [[https://www.sqlite.org/download.html|here]].
<!-- See script {{firefox_places_sqlite.7z}}. -->

=== How to re-enable copy-paste on the form element that has this disabled? ===

<note tip>
Taken from [[http://www.pcc-services.com/kixtart/firefox-lockdown.html|this page]]: set ''dom.event.contextmenu.enabled=false'', however it will break functionality for sites like Google Docs.
