Just run this apt install command
sudo apt install pepperflashplugin-nonfree browser-plugin-freshplayer-pepperflash
After this restart your browser and check Adobe's site to verify if your Pepper flash is working and showing at least version 32.
As you'll see below it will download the latest version which is currently 32 and this was not possible with the old/crappy deprecated adobe-flash plu........
A lot of times this is actually caused by simply not having Firefox installed at all.
selenium.common.exceptions.WebDriverException: Message: Can not connect to the Service geckodriver
Opening Firefox from the CLI reveals the following as the cause of the error:
Query failed: Error: Error(s) encountered during statement execution: no such table: moz_favicons
The symptoms of this issue are that in the address bar you cannot hit enter to browse to a site/url/address and your history cannot be accessed, nor does your history show up in the address bar when typing previously used addresses.
This usually happens because you've........
If you visit a site that exploits the WebRTC vulnerability including whatismyipaddress.com it may show "Local IP Address" which would be the real IP of your machine.
The vulnerability works on Windows and Linux machines (contrary to false information on the web which claims it only affects Windows).
The above works and happens even if you are using a proxy or VPNaccount like ProVPNAccounts.com
It is easy........
This is not about systemd/systemctl and not about "onboot" so there's no rc.local trick here but it's the GUI/Gnome etc when a user logs in that a command is launched.
Put this in your home dir

Below are the common errors you'll get with named AKA bind if your time is incorrect.
The simplest solution is to install and run ntpd to correct your system's time (install ntpd if it is not installed)
systemctl start ntpd
systemctl enable ntpd

Here is the only solution Ifound that works in Firefox:
*Note you could basically just copy all of the commands in bold (the rest just shows the output)
sqlite> .clone places.sqlite-fixed
In your browser go to "about:config"
Right click and choose "New" ->"String"
The name should be:

You don't even have to restart to make this work.........
I was sure this was a Centos bug with OpenSSL, Apache, MySQL or even PHP. I tried everything but nothing helped. One clue is that if you check the Apache logs you will see nothing in the access logs until minutes later (this means Firefox has not even passed your request to the remote Apache/htttpd server).
When even accepting the invalid certificate message that would show up minutes later when trying to "View the Certificate" Firefox would freeze. This bu........
Using Apache 2.2 and PHP5.6 PHPBB3 is very slow to respond. Actually for some reason it takes so long to even register a log entry in access_log as in several seconds or a few minutes later it shows up in Apache. All other vhosts and Apache access stops working and freezes until the request to access PHPBB3 slowly completes.
It seems to randomly be slow if you stop using it whether for posting or reading the forums. I've migrated to different machines including........
In Firefox I cannot connect to any website, proxy is disabled and outside network access is confirmed, no system or manual proxy was set on this Linux Mint/Ubuntu system. Normally this can be caused by proxy or DNS problems and the weird thing is that traceroute and ping to other IPs worked fine but even connecting to sites by IP was not working.
The connection was reset
The connection to the server was reset while the page was loading.........
Your firefox is out of date if you get errors like below:
Secure Connection Failed
Install the "Flashblock" plugin because we all know most unwanted high CPU usage situations come from the browser usually because of a looping Flash ad taking up 100% CPU.
The solution is to install the "Flashblock" plugin that doesn't allow any Flash to load and play unless you click on the placeholder.........
This is very annoying and also hard for web developers who want to see how things look on Android. You may be fooled into thinking you have an unclosed bracket or incompatible code but this is the "text inflation feature" which I feel should be disabled by default. It works so inconsitently that one block of text will appear small while the other will be huge and is quite annoying.
The solution is simple

Here's a proven example of what a bad hard drive can do, it was technically functioning OKin a RAID array but the system became extremely low and the load become high and IOWAIT was even higher and I always thought it was a bad application. The truth is that this failing 1TBHitachi has slowly gotten worse and caused huge slowdowns, (eg. 100% load on Thunderbird waiting for e-mails to load etc..). After swapping it out, tabs change instantly, emails are not lagged, and........
This is very handy if you're too busy and don't have time to download whatever files you need.
The -D specifies the domains allowed, this is because I specified -H which means foreign hosts are allowed, if you don't restrict them you'll end up going to the whole internet via ads and other links just like a search Engine would follow.
-l 0 specifies to go deep, to as many levels as possible/as exist.

I've used rsync again for this because I found it very simple, I've only excluded the Cache directory since it's not necessary and could be several GB in size.
rsync -Phaz --exclude=Cache/* email@example.com:/home/user/.mozilla/firefox/profile.default/* /home/user/.mozilla/firefox/ec1n9opl.default/

After about 15 tabs I believe, they become hidden on the right side and are accessible only by furiously clicking the "right arrow" and even then it takes forever and honestly this hidden tab feature seems to slow down everything.
If you enter "about:config" in your browser without the quotes just set this value to get rid of this annoying (one of many new) feature from Firefox (set it to false and restart your browser):
So you've just purchased your SSL cert, renewed it and installed it or maybe you've had it installed and working fine all the time with all other browsers but you've upgraded to a recent version of Firefox and suddenly get the warning "Error code: sec_error_unknown_issuer" error.
This is terrible since if you bought an SSL cert, you are most likely using it for trust purposes for your business and obviously that message will scare away most potential customers.........
Type "about:config" in your browser and then search for "Quit"
Set these values to true
In Firefox type "about:config" in the address bar.
Search for "browser.urlbar.trimURLs;false" and set it to true, then you'll have the http:// and https:// back.
Firefox talks about the greater good but unless they don't care about security why would they hide if the url is secure or not?........
When double clicking nothing happens/it doesn't open and when executing as ./firefox-bin you get this error:
./firefox-bin: error while loading shared libraries: libxul.so: cannot open shared object file: No such file or directory
All the .so files reside within the directory of Firefox that you extract from the binary .tar.gz from Mozilla, it's just that your computer doesn't know/recognize where to look for them.
/tmp/J_5JHKXU.bin.part could not be saved, because the source file could not be read.
Try again later, or contact the server administrator.
This is actually not a download problem related to the server/site you're using but actually some weird bug with Firefox. I know because no matter what site I tried to download from this error kept happening.
Simpy restarting Firefox was enough to get things working again.........

I'm mentioning this because I keep forgetting what port the management is on for the web interface (since newer releases of VMWare server took away the superior stand alone client).
So remember it is port 8333 and sometimes you need to restart vmware-mgmt service and also enable sslv2 in your Firefox or it won't connect.........
This is an easy fix and highlights a huge issue again with Linux and Flash still not playing nicely/working as well as Windows yet.
Solution - Go to "about:config" and disable the two entries (set them to false):
Use Mozilla Firefox, not Internet Explorer - You'll be glad!Hey guys,
I just thought I'd recommend that everyone switch to Mozilla Firefox as their web browser. You can find it at http://mozilla.org
It is free and it is much better than IE. It has a built-in popup blocker which works great and most importantly, it doesn't have a million critical security flaws which could compromise your security such as passwords for on-line banking etc..........
