Firefox for Android Support Forum

This is driving me insane. On mobile data (3,4,5g) Firefox will not open any websites, it just sits with a white page until eventually I get "connection reset". Every other browser on the device works fine though, and Firefox can access sites when on WiFi.

I have uninstalled and reinstalled the main app *and* installed focus,beta and nightly versions,all have the same problems. Permissions on mobile data are allowed.

I cannot even get a sensible log or network trace out of the browser as there are no Dev tools.

It sometimes feels like Mozilla are trying their absolute hardest to lose users, I even had had the old "browser uses 12gb of memory for two tabs" problem on desktop the other week.

I am using firefox on android device running android 12. Have tried websites like: youtube, 9gag, and basic searches with duckduckgo and the websites don't load, or no indication of loading happens, or sometimes slow loading occurs and stops after progessing midway of total bar length. I see the same issue on firefox beta, but on chrome. I am using ublock origin as an addon. On the main browser i have a bunch of open and inactive tabs, but on beta almost no tabs. The only thing that might unblock my issue is to disable my phone's private dns which points to google or adguard. But even with it off, i still see the same issue appearing.

172.16.32.1 is the login page for a WiFi offered by my landlord. Sometimes I am able to go to that page and login and sometimes your browser refuses me access. Please help me fix this and allow me to use my landlords WiFi. If you are unable to assist, please direct me to a browser I can download that will allow me to use my apartment's wifi. Thank you and have a great day.

As shown in the image, I'm having this issue where the Android version just refuses to use the internet for some reason. Wifi is working perfectly fine, yet it just doesn't do anything when I click enter on the address bar. Any idea on what's could possibly the root of the problem? It's just stuck there for the last 15 minutes.

Hi been asked to put up this question. It's the same as on the forums. Android Firefox app has stopped working with mobile data. Works with WiFi. Have tried all the workarounds suggested. Nothing works. Cleared cashe deleted data reinstalled and restarted. Looks like time for a new browser. Shame really I've always used FF.

Really do Like Firefox/Mozilla; Appreciate the opportunity offered to apply an app to link to cell phone; However my Cell Phone does Not allow apps, No Internet Connection. Should I go to 'Settings' to opt-out for the app??

Just started happening the past few days, Firefox on my Android won't work. Keeps saying "Proxy Server Refused Connection" but I'm watching the proxy server (Squid) logs and it's not hitting the logs. Chrome on the same Android device works through the proxy, so do several other apps. They show up in the Squid logs as I would expect.

But Firefox, which was working with the proxy a few days ago, doesn't even appear to be trying.

Firefox 117.1.0 on Android 13.

Yes, if I disable the proxy in my WiFi settings then Firefox works. Turning the proxy back on and Firefox goes back to saying the proxy refused a connection.

Using tcpdump, I can see Firefox is hitting the squid server but squid is not logging the connection. Firefox changed something, everything else works except Firefox.

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.

Device: Oneplus 8T (KB2003) OS: OxygenOS 13.1 (Android 13) Firefox version: 117.0.1

How to bypass this, please? I beg you!

It's always the same link. It ruins my business immensly. I have searched the whole internet on how to disable it but I found no solution.

This is via Bluestacks 5 Android Emulator. It doesn't have any Anti Virus enabled. All virus protections are disabled. I have disabled Enhance Protection and disabled HTTPs scanning inside Firefox settings but that didn't fix it.

Please help me!

I use Firefox nightly and about a month ago using mobile data completely broke. Everytime with every site it says "Connection timed out". Every single other application and browser works on my phone with mobile data but not Firefox. I've tried reinstalling Nightly and installing the regular version but the issue persists. I do use a tracker blocking application but I have Firefox completely whitelisted in it and it's been working fine before.

Hi. I have been having problems with Firefox. I can not open the app for a few hours and when I do I get a grey screen. I also notice that the padlock at the top of the screen has a red line through it.

I check the padlock and it shows the connection is not secure, even on google sometimes. It also takes forever for the page for reload itself and then it becomes secure and only then can I move to a different tab as I can't do that when the connection is unsecure. I also can't reload the page as it doesn't do anything.

When the page finally goes back to normal it only last so long before the page ends up unsecure when I've not visited the app for a while again. This is getting beyond annoying now.

Sometimes things go really bad when this unsecure connection occurs because the whole app will sometimes restart and I'll have lost all my open tabs, which when I check the recent closed tabs area it doesn't show them because they weren't closed manually which is also annoying.

Hope something can be done about these problems. I sometimes get the unsecure connection on the Firefox Nighty but that seems to refresh the tab within a few seconds of my opening the app.

Just today all my bookmarks , every other site that I try, shows "address not found" and Also each site shows "Your connection is not secure".

I have only 1 add-on, UBlock Origin. Whether this is OFF or ON doesn't matter.

HTTPS-Only Mode : OFF or ON doesn't matter.

I've also re-installed Firefox Android, no change.

Thanks, Rod

PS: WiFi & Cell connection very good.

Ever since I downloaded Firefox 108.0.1 on Jan 16, I have been unable to access logibiztech.com. I get the message "SECURE CONNECTION FAILED ERROR CODE PR-CONNECT-RESET-ERROR"

Hello there,

Unable to open websites through Android phone. While trying to open or browse got message that THIS WEBSITE REQUIRES A SECURE CONNECTION. What to do to solve this issue.

Kindly help

Now what? Another useless POS. Sorry, I've had it with this security crap. No joy on multiple Android devices, every site I tried, bar none. No VPN or anything abnormal connectionwise. Every other browser on multiple devices works fine.
