Mozilla Firefox is a free and open source web browser developed by Mozilla Foundation and its subsidiary, Mozilla Corporation. Firefox is available for Windows, macOS, Linux, BSD, illumos and Solaris operating systems. Its siblings, Firefox for Android and Firefox for iOS are available for Android and iOS respectively. It debuted in 2002 and by the end of 2009, it was the world’s most popular browser. As of April 2018, Firefox holds 10.14% of the global market share across all desktop and laptop web browser market making it the 2nd most popular web browser behind Google’s Chrome which has a market share of whopping 69.64%. It is the 4th most popular browser when all platforms are considered with a market share of 11.78%.
Though Firefox is a very capable browser, it has its own fair share of issues. One of the most dreaded issues is the Proxy Connection server issue. It occurs when one tries to open a page on any website in the Mozilla Firefox and out of nowhere an empty window appears with the text:
The proxy server is refusing connections
Firefox is configured to use a proxy server that is refusing connections.
Check the proxy settings to make sure that they are correct.
Contact your network administrator to make sure the proxy server is working.
If you are someone who does not understand, what the problem is an intermediary computer between your device and the Internet. And if there is some issue with that intermediary computer, then the error The proxy server is refusing connections will appear in the browser. This issue is very well known on Mozilla’s Firefox and occasionally on the TOR browser.
Now without further ado, let us get started with the solutions.
Check For Firefox’s Proxy Settings
- Open the Firefox browser.
- Click on tools and then options.
- From the list of Options, check for the Network Proxy section and once found, click on the Settings button found adjacent to it.
- In the new window, select either “No Proxy” or “Use system proxy settings” and click ok.
- Now, relaunch the Firefox browser and try opening any webpage.
Most likely, the problem should be resolved. In case it still persists, look out for the next method.
Check The System Proxy Settings
- Open the run dialogue window by pressing the Windows key + R.
- In the Run dialogue window, type cpl and press enter to open Internet Properties.
- In the Internet Properties window, click on the Connections tab and then click on LAN Connection.
- Toggle off the option for Use a proxy server for your LAN and then click on ok button.
Now, try loading your page on Firefox again.
If the problem still persists, check if this issue is just limited to Firefox or is common for all web browsers. If other browsers work fine, clear the cookies and the cached data stored by Firefox. Disable all the add-ons and plugins including the VPN services, if any. You might even consider reinstalling it. If other browsers have the same problem, you should consider resetting the network settings. There can be a possibility of your system being affected by a virus, trojan or malware. Run a full device scan by using any certified antivirus. There is also a possibility of your modem malfunctioning. In that case, contact your Internet Service Provider.
To reset the network settings, follow this step:
Open the run command prompt and run the following commands one by one.
netsh int reset all
netsh int ip reset
netsh winsock reset
netsh winhttp reset proxy
