Firefox on a
Linux system running CentOS 7 to version 52.8.0-1 with yum upgrade
firefox. When I opened Firefox afterwards and put google.com in the
address bar, I saw the message below:

When I went to another site, wikipedia.org, using
HTTPS, I saw
the same message. I checked to ensure that the web browser wasn't configured to
use a proxy by clicking on the icon with the three horizontal bars at the top,
right-hand side of the browser window and selecting Preferences, then
Advanced, then Network, then Settings. The setting
was "No proxy." I then right-clicked on the "Your connection is not secure"
page and chose View Page Info. When I clicked on the Security
tab, I saw the "Owner" value listed as "This website does not supply
ownership information." In the Technical Details section, I saw "Connection
Not Encrypted" and "The website www.google.com does not support encryption
for the page you are viewing," even though the URL listed was

If you use a hotel's Wi-Fi service, a free WiFi service provided by a
restaurant or other business, or some other public WiFi service, when you first
open your browser you may see a web page asking you to accede to terms of
acceptable use policy, or to provide some authentication
information, e.g., perhaps your name and room number for a hotel,
or to provide payment information if you are accessing a wireless
service that is not free. You won't be able to go elsewhere on the
web, at least not easily, until you deal with the demands/conditions
specified on the captive portal page.
If you are seeing a "Firefox has detected that the server is redirecting
the request for this address in a way that will never complete" message,
the problem may be resolved by removing cookies or history associated with
the site, but you might also need to check the cookies exceptions list in
Firefox; that's how I was finally able to resolve a problem accessing a
particular site that I could access in another browser on a system, but
not with Firefox.
When trying to log into the
website using Firefox 52.0.1 on a Windows 10 system, I saw the message
below after being redirected to http://cli.linksynergy.com/cli/common/login.php:

On a Macintosh, aka Mac, OS X/macOS system, the
directory where the Firefox web browser stores its data can be found at
where account_name is the relevant user name.
The profile directory for the account will be a sequence of 8 characters
followed by ".default". E.g.:
$ ls "/Users/jasmith1/Library/Application Support/Firefox/Profiles"
Within that directory will be a cookies.sqlite file within which
Firefox stores browser cookies. You can view those cookies outside of
Firefox using the
SQLiterelational database management system software found on
OS X/macOS systems. You can examine the sqlite file with the
sqlite3 command, which you
can run from a command line interface (CLI), i.e., a
Bash shell prompt, by opening a
Terminal window; the Terminal application is found in the
Applications/Utilities directory. You can
examine the structure of the database using the SQLite .schema
command. There is a moz_cookies
table within the database.
web browser stores information about its user settings and state in a "profile"
directory for each user. On a Mac OS X system (now macOS), such as my MacBook Pro laptop, you
can have Firefox open a
Finder window showing you the relevant profile folder or you
can find it from a command line interface (CLI), i.e., a shell prompt, by
opening a Terminal window (you can find the Terminal program in the
Applications/Utilities folder). For the latter method, you can see the location
of the profile directory by issing the command
ls -l ~/Library/Application\ Support/Firefox/Profiles.
(you need to put a backslash before the space in the directory path)
$ ls -l ~/Library/Application\ Support/Firefox/Profiles

The following steps can be taken to remove the cookies associated with a
particular website in the Firefox browser. Note: these steps were taken on
Firefox 50.0.2 on a Microsoft Windows 10 system, but should be applicable to
other versions as well.
Click on the 3 horizontal bars at the upper, right-hand corner of the Firefox

My wife could not hear audio today when she was viewing
videos in the
Firefox browser. She thought the problem occurred after the automatic update
of Windows 10 on her system with the Anniversary Update. The YouTube audio
setting was not muted and was turned up to a level where I should have heard
sound and I found that I could hear audio for a music file outside of Firefox
and I could hear audio for the YouTube video she was trying to view within the
Edge web browser on the system. And when I went to the
CNN website, I was able
to listen to the audio associated with a news video on the site.
Corporation, which produces the Evernote note-taking application,
unfortunately, doesn't provide an application for Linux as it does for
Microsoft Windows and OS X, but you can use Evernote from within a browser,
such as Firefox. To install Evernote support from within Firefox, take
the steps listed here.
I needed to be able to retrieve a Firefox bookmark for an account on a
MacBook Pro laptop running OS X Yosemite (10.10.5). I wanted to be able
to view the bookmarks from a command line interface (CLI), i.e., a
shell prompt that I would get in a
Terminal window. On an OS X system, the bookmarks and other account-unique
information is stored beneath the profile directory for the
account, which you can find beneath the ~/Library/Application
$ ls ~/Library/Application\ Support/Firefox/Profiles
Within that directory is a places.sqliteSQLite database.
OS X comes with the sqlite3 program for creating, viewing,
and editing SQLite databases - see
Using SQLite for
information on how to use the program.
