Firefox for Android Community Forum

Firefox on my android phone times out on any webpage whenever I am not connected to a Wi-Fi. All webpages and IP addresses timeout with no response. Same issue occurs on Firefox Beta app and Firefox Nightly. All other applications work as expected with full internet access on mobile data. The same pages/addresses respond as expected on Chrome and the built-in browser.

Simply put, all Firefox apps have no internet connectivity on mobile data.

Solutions I've attempted with no success or change: Re-install Firefox. Logging out of Firefox Sync. Clear Firefox data and cache. Disabling tracking protection. Disabling HTTPS-only mode. No proxy settings are enabled. Confirmed Firefox application has mobile data network privileges. Disabling, re-enabling mobile data network privs. Installing Firefox Beta and Firefox Nightly; same issue.

Another possibly related issue: Firefox does not follow routes from a Cisco AnyConnect VPN on my phone. Opening pages/IP addresses routed through the VPN are rejected or timeout as if the VPN is not active at all. The same pages/addresses respond as expected on Chrome and the built-in browser. This occurs over Wi-Fi as well, of course nothing works on mobile data as described above.

Hi,

I have a custom site on my ISP's webspace that can be access via an https:// link. Firefox for Android (129.0.2) on my new phone (Samsung a35, Android 14) says that it's not secure, which means I frequently have to go though the not secure>advanced>accept risk process.

The problem is that this is literally the only browser instance I have that thinks it isn't secure. Chrome, on the same device, says it is, Firefox for Android thinks it is on two other devices. Firefox for Windows thinks it is. I can find no other browser on any device or platform that thinks there is any problem.

Any hep appreciated.

When using Paypal I keep getting warnings from Firefox that it is an unsafe site. What steps can I take to make Paypal safe and stop getting the warnings? I've looked in the settings area but can't find what might relate to making a site safe.

Hello,

On Firefox for Android, I get "Proxy is refusing connection" error while attempting to connect to any site on the Internet. But I didn't configure any proxy connection for Firefox! Moreover, this error happens when I use my home Wi-Fi network, but browser works properly when using cellular data or any other Wi-Fi network. Also, browser works for some time if I start VPN (Psiphon in my case), stop Firefox through Android settings, clear cache and start the browser again.

Best regards, Peter

I can't sign in to my GTB accounts with my password. The error message has always been like this:"connection is insecur" What can I do to allow me have the benefits of accessing my GTB accounts.

Hello,

The default browser in our company is Firefox. We have some internal websites now available from outside with mTLS.

This is working fine with Firefox on laptop (fedora), but I cannot make it work with Firefox on Android (which is crucial as the aim of this project is to have those apps securely available to all or employees from outside).

I installed the user certificate in the Android "User credentials" trust store, but Firefox (version 128.0.1) is not offering to use that certificate for mTLS, and just show a "Secure Connection Failed" error message.

How can we have Firefox on Android using the user CA to access those applications?

Thank you in advance for your feedback.

Best regards,

B.

when I am downloading something from Firefox then my internet speed decrease to below 1 mb per second while my regular WiFi speed is 200mb per second. in chrome or playstore i don't face any problem but in Firefox it is always there.
