4-25-22: Same as b4 really. But now sends you to some african or other obscure 3rd world IP without your knowledge! Be careful with this addon. Some sites can id it and block it, so their scheme is not perfect. Takes a long time to connect. Limited to a few proxy changes before they stop your changing ips. Cannot use a firewall with this (at least the developers don't tell you how). Expect possible hacker attacks and exploits with this, although nothing serious has happened thus far. WIll get you into many sites inaccessible by other means. It's slow and requires changing proxies frequently because the one they send you too first is overcrowded or not working. Need a better user guide, I haven't found one yet.
UPDATE 1-10-22 just as bad as it has always been. Takes forever to connect. Then they limit you to just a few proxy changes even if you don't actually used the proxy for data transmission. Being picked up now by some sites as spammer IPs. They change your proxy IP without input to you. Bad privacy policy. You get what you pay for in this case a slow, unreliable proxy. You can get into many sites using this however, but it's a royal PITA to use it.
UPDATE 9-29-21
If you do a whois lookup for tuxler you get GOOGLE.com
What does that tell you? Corrupt, censoring company that invades your privacy. The latest is that Globe Wifi ISP is firewall blocking tuxler OR tuxler is selectively blocking users. Cannot connect with globe wifi portable routers. They report not connected to interernet when you clearly ARE connected and everything else works. Tuxler just keeps getting worse and worse. If they think I would ever pay for their garbage vpn, they are mistaken. Uninstall and reinstall of program does no good because it's being blocked by Globe wifi. If there was every a crap ISP it's globe. Without a doubt the worst isp in existence.

UPDATE: 6-10-21: The new user interface of Tuxler is a definite improvement, more stable , faster.
Their surfing has improved a tad, but still very unstable requiring frequent closing and reconnecting of the program to load pages. This is the biggest flaw with tuxler "VPN", cannot keep a connection that actually works. I believe the program opens windows FW and no protection from hackers. It's better than before but not by much.
update:3-27-21: Tuxler has to be the lamest VPN out there. Hackers galore fucking with your connection, dropping you, revealing your home IP and other hacker shit. Watch their servers, some are more hacked than others. Frequently stalls with frequent disconnects regardless of browser used. This vpn is good for ONE thing and ONE thing only. Getting into a site that blocks proxies. But even then it does not work universally, some sites STILL detect not a normal connection. Use at your own risk
update:4-1-20. Rarely using tuxler any more found a better competitor. Notice here that all the 4 and 5 star reviews are only stars or one word comments? Why? because the are probably fake put there by Tuxler. Not an honest company either with their reviews or program.
update:3-31-20: tuxler is probalby pressuring reddit to delete negative reviews of the software from it's site. Review placed there was almost immediately deleted. This program is not honest and easily hacked and you will have trouble accessing sites based either on tuxler direct blocking of the site or hackers blocking access through tuxler. Hardly using it any more, found a better one that also has residentail proxies. Competitors are coming won't be long b4 tuxler must shape up or ship out.
3-18-20 yes still using tuxler cuz their residential IPs are mostly undetectable as proxies. Other than that it's pretty lame. Now they are blocking access to certain websites such as reddit.com. That's even after you cleared all cache and other info, changed the browser settings, changed the browser, you are still blocked by tuxler regardless of IP. What a lame outfit, never pay for something like this.

3-17-2020:
THE FREE RIDE IS OVER-SITES ARE NOW DETECTING THIS ADD-ON AS A PROXY. REASON IS IT KEEPS CHANGING IPS WITHOUT INPUT, EASILY DETECTABLE AS A PROXY AND BLOCKED FOR REGISTRATION,ETC. ALSO THE INABILITY TO CHANGE PORTS FOR THE SITE MAKES IT OPEN SEASON FOR THOSE THAT WANT TO HACK/BLOCK YOUR CONNECTION. MORE AND MORE WORTHLESS BY THE MINUTE.

WARNING: GETTING CONSTANT HACK MAN IN THE MIDDLE ATTACK ATTEMPT FROM TUXLER "PROXIES" (SO CALLED RESIDENTIAL) AND OTHER HACK BEHAVIOR REQUIRING CONSTANT EXIT AND RESTART OF PROGRAM-I THINK THEY ARE TRYING TO GET YOUR REAL IP BY DISCONNECTING YOU AND THEN THE SITE GETS UR ACTUAL HOME IP. BS ADDON. NEVER PAY FOR SOMETHING LIKE THIS. ONLY USE WHEN YOU DON'T CARE IF THEY GET YOUR HOME IP AND YOU HAVE NO OTHER WAY TO ACCESS A BLOCKED SITE. COMPETITIORS HELP, THIS SERVICE SUCKS, IT NEEDS SOME COMPETITION.
The ONLY good thing about this add-on is the ability to mask your IP from proxy identifying website programs. Other than that it SUCKS. Now being blocked either by ISP or downstream, not even able to do that any more. Slow, frequent disconnects requiring restart. Very limited proxy selection in free version, auto locks your proxy after a few choices. No privacy,theycan do whatever the hell they want to with your data. Like I said very limited use, only to hide ur IP from websites that are unable to identify it as a proxy. update 10-26-19-getting worse by the minute. difficult to connect takes forever. often cannot integrate with browser such that u have to check the ip frequently to make sure it is working,which it often is not. Just really lousy performance. Waiting for competitors that should offer the same residential proxies without the bad performance issues.
Update 11-3-19. Getting worse by the day: drops connections constantly requiring restart. Stalls constantly. Switches proxies without warning in the middle of browsing. Often will not change browser settings so you real IP will show up. Great POTENTIAL, too bad they cannot manage it properly. note 3-23-20: posted negative reviews on the corrupt Reddit site and they were summilarily deleted by reddit. apparently reddit answers to tuxler when it comes to negative reviews of their vpn. also after I posted that, many others came forward commenting on my post about how lousy tuxler is. Hola is even worse. Wanted a residential free vpn that actually works and is not filled with hackers and where you can change the port settings, which u cannot with tuxler-a hackers paradise
