Usernames and passwords are not saved | Firefox Help
In my case I'd made an exception (to *not*, ever, save a password) for the sites that I wanted to save my password for. I thought it had something to do with the HTTP Basic authentication, but nope.

Firefox Bookmark Backup Reader/Decompressor — Fx File Utilities
Firefox creates frequent backups of your bookmarks. Automatic backups are compressed using Mozilla's flavor of LZ4 compression (.jsonlz4 file extension), while backups you create yourself (in the Library window) are not compressed (.json file extension by default). This tool can convert a backup file to the HTML export format.

this looks better */

Your first extension - Mozilla | MDN
On macOS 10.14 (Mojave), I had to
<code class="language-bash">
sudo port install nodejs10
sudo port install python27
sudo port select --set python2 python27

# install NPM modules into $HOME
npm config set prefix $HOME/.local/lib/node_modules
echo "export PATH=$HOME/.local/lib/node_modules/bin:$PATH" >> ~/.bash_profile

# this needed 'python2' in the PATH (for node-gyp, whatever that is)
npm install -g web-ext

# then build the extension
web-ext build

Also, try to use the linter on the built '.zip' file:

<code class="language-bash">addons-linter web-ext-artifacts/*.zip</code>

Otherwise you might get a "Can't install addon because it seems to be corrupt" error, which probably means that you just have a syntax error in your JavaScript, or else the manifest.json is missing a 'content_scripts' 'matches' key (ref:

Unwanted context menu behaviour after update to Firefox 61.0 - Right clicks are automatically double clicking : firefox |
After some trial-and-error I was able to fix the issue in about:config by toggling ui.context_menus.after_mouseup to true. The default is false. I believe this may have something to do with the fact that I'd previously toggled dom.event.contextmenu.enabled to false to always allow for the context menu, even if a site disables it.

Awesome Bar - Search your Firefox bookmarks, history and tabs from the address bar | Firefox Help
Possible workaround for (Firefox assuming anything with dots in it is a domain name).
If you are looking for a specific type of result, like a bookmark or tag, you can speed up the process of finding it by typing in special characters after each search term in the address bar separated by spaces:

* Add ^ to search for matches in your browsing history.
* Add * to search for matches in your bookmarks.
* Add + to search for matches in pages you've tagged.
* Add % to search for matches in your currently open tabs.
* Add # to search for matches in page titles.
* Add $ to search for matches in web addresses (URLs).
* Add ? to search for matches in suggestions.

How can I disable searching and domain guessing from the Firefox Address Bar, while keeping other features? - Super User |
The settings mentioned in the accepted answer will prevent, for example, 'localhost' from redirecting to '', but this still doesn't stop Firefox from trying to visit a non-existent web site if your search term has a period in it. So a search like "vcruntime140.dll" will still assume that ".dll" is a TLD.

However, I blindly discovered that putting a "?" at the beginning of the query is enough to turn of hostname detection, and pressing Ctrl+K will do that, and focus the Awesome Bar for you.

See also: and (section called "Changing results on the fly").
Go to about:config and set the following preferences to false:


True (default): Try to fix up http://foo to http://(prefix)foo(suffix)
False: Do not second-guess the user

Animated images - MozillaZine Knowledge Base |
Pressing the "Esc" key on Windows (other OS may be different) will pause animated images on the current website. Note: Starting in Firefox 20, this is no longer the case due to the fix for bug 614304 unless resolved in an upcoming patch (see comment 45). The SuperStop add-on by Gavin Sharp ( is an alternate solution.

how to display local shell-script/s in browser/firefox? - Unix & Linux Stack Exchange |
The way data is processed in a browser depends on the MIME type declared by the server. If you want your browser to render it as html, which is most likely a terrible idea, you can change the Content-Type header the server returns so that it reflects the type of your data, which would be text/html; charset=utf-8, and the Content-Disposition header to suggest the browser what to do.

My solution was the following (in a '.htaccess'):
<code class="language-apache">
<Files *.sh>
SetEnvIf Request_URI "([^/]+\.sh)" FileName=$1

# ref:
Header set Content-Type "text/plain"

# not needed, and doesn't work alone, since the browser is configured to
# download "application/sh" rather than display it inline; just telling the
# browser it's "text/plain" is enough to achieve the aim
#Header set Content-Disposition "inline; filename=\"%{FileName}e\""

Bookmark Toolbar Menu Button – Add-ons for Firefox
Show the contents of the Bookmarks Toolbar in a drop down menu. This compresses the bookmark menu into one button that you can put on any toolbar you want to.

Popups (like bookmarklets) get blocked, though, and there's no way to confirm the popup warning banner, because the page gets reloaded immediately, at least for the Pinboard bookmarklet.
