from v67.0, firefox prompts for authentication to the proxy, seemingly every time a new domain is called, making firefox unusable, it takes 20 to 30 authentications to load some sites.

configured to use manual proxy config use proxy for all protocols checked Do not prompt for authentication if password is saved is ticked. [doesn't affect behaviour] Proxy DNS when using socks v5 is ticked [doesn't affect behaviour]

I get the error message at the bottom. Yes, my firefox already has "no proxy" selected in the preferences page. I'm able to use Edge fine, but for firefox it does not seem to matter what network I try to connect to. Occasionally it will load some websites like Wikipedia, but then immediately fail anything past that or if I try a different site. Sometimes if I try youtube it will only partially load and then the unable to connect to proxy message will appear in the embedded page videos. Sometimes trying a network reset and then restarting the pc fixes the issue, sometimes it doesn't... I don't know if it has anything to do with this issue but I'm also using NordVPN. Sometimes I am able to get to websites before nord connects itself, sometimes it doesn't matter even if nord does not try to autoconnect. Sometimes it will connect and my internet works fine. I've tried setting up an actual nord proxy through firefox preferences and it doesn't help either. Proxy or no proxy I can't get things to load. When attempting to reach sites I'll get a little message in the bottom left corner of firefox as it tries to reach a website, stuff like: reading img-getpocket.cdn.mozilla.net, looking up *sitename*

Don't know what the problem is and I exhausted my limited IT knowledge a while ago, googling for answers hasn't helped.



Unable to find the proxy server

Firefox is configured to use a proxy server that can’t be found.

   Check the proxy settings to make sure that they are correct.
   Check to make sure your computer has a working network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

I work for a state organization use a secure proxy server and have an updated certification. That said Firefox does not recognize the cert and throws an error on every single page I open. Some pages do not give me the option to create an exception and to be honest nobody would find a browser useful if they have to create an exception to reach every page. I do not have the legenda file that is mentioned it other posts I already checked. I cannot change my cert it is correct. How does this get fixed or do I just delete.

Firefox 60.2.0 ESR on Win7 and Win10 - but a lot of versions below had same problem

We use a proxy - normally with a .PAC file via System Settings but tested settings within FF with .PAC file or directly entered proxy.

It prompts after every launch of FF for Proxy credentials and NEVER shows the "Would you like Firefox to save this login..."

For any other site it always offers storing the credetials and it works like it should be.

EXCEPT I found one solution: When launching FF Cancel the "Authentication Required" (sometimes 3 to 7 times canceling). Than open any page on the web and authenticate against the proxy - it will show the "Would you like Firefox to save this login..." and it is visible in the password store. Thereafter everything is operational.

Another problem: If you ever click on "Never save" for proxy saving credential this proxy site it NOT added to the Exceptions list and cannot be removed and I did not find any way to solve it except removing the Firefox profile.

Tested with German and English Version Searched for a solution since a year ever and ever again configured dozens of parameters in about:config which I found on the web. Credentials for every other site are always saved.

Users with a old Firefox profiles with saved proxy credential do not have this problem, only new FF profiles - since at least a year possilbly longer.

When I open new tab it just shows blank screen and it keeps loading forever, tried safe mode and reinstalling and it doesnt change a thing. Also tried disabling addons, pluggins one by one and my f secure antivirus with no success. Problem doesnt happen all the time, but it does at least 70% of the times. Sometimes it helps if i copy the page address and open it with a open in a new tab button.

I know the support forum isn't the best place for this, but I really don't know how else to get people's thoughts on this. I get the impression the Devs have no idea how or why some people use Firefox.

I've been using Firefox on and off before it was even at version 1.0. When I started working at a big company in 2008 with a locked-down IT policy, Firefox had me 100% covered, and did everything I could ever dream of wanting it to do.

In the last year or two, key features that always made it a winner have slowly been disappearing, and now it has gotten to the point that it is actually barely any better than IE11, and no different than Chrome. Why? Big reason is now addons don't work, or can't work the way they used to/need to, but it goes beyond that.

1. I can no longer have my homepage open, when I load a new tab. This is absolutely mind boggling, even internet explorer can do that! NOTE: My homepage is a webpage saved on my harddrive that I made that gives me quick access to everything I need to do for work. I used to be able to load it natively, then it became something that required an add-on, and now it is completely broken, and impossible to do.

2. Devs clearly don't understand the concept of a PROXY. Lots of people (i.e. in corporate environments) have everything go through a proxy. I can't even use the firefox installer anymore (as I discovered yesterday) because it requires a direct connection to the internet.

3. Speaking of Proxy issues, when I open firefox, it immediately needs to connect to the internet, resulting in proxy authentication pop-ups. These used to be Auto-accepted with the addon AUTO-AUTH, however with the new web API crap this apparently isn't possible. There are settings in firefox that are supposed to auto-accept proxy-logins, but they don't work. So - I'm stuck hitting enter every single time I open the bloody program. There is no way to delay or stop firefox from automatically trying to connect to the internet which is also stupid.

4. I could go on, but what's the point... the Devs don't care. Time to go back to FF v51 or whatever version it was before things went so wrong and hang on to that, with my windows 7 installation. Sigh.

In Firefox i set an SOCKS5 proxy. But for the past months it is numerous case that i accidentally accessed webpages being not proxiffied / not using proxy and i was unaware about this and realised the fact too late..

For example after proxy managing plugin installation or i temporarilly disabled proxy.

My aim is to prevent me accessing webpages without proxy. I mean somehow locking the firefox proxy configuration so even plugins cant modiffy my firefox proxy setting.

Just want to be sure i will never access internet without proxy.

Having latest Firefox and WIndows Vista.

PS: i sitll need unproxiffied access to certain websites. I have the whitelist in my Firefox proxy configuration now.
