Firefox for Android Support Forum

• Opening links results in an error that says "This web site requires a secure connection."

• Upon checking the URL you will see that https:// will be added before href.li/?https:// which results in https://href.li/?https://example.com

• When I removed the first https:// then the website will open correctly without the error.

Thank you.

I recently logged into the WIFI of my TAFE, which uses a proxy, only to find that Firefox would not work. 1 hour of crazed searching later I have found that you pretty much *cannot use a proxy with Firefox on Android*.

Sure technically you can download the FoxyProxy add-on or go to about:config and change the settings there (but not on the stable build which y'know most people use) but the fact that the stock, stable install has *zero* support for proxies, which are extremely common on school/work networks, is absolutely unacceptable. This is *basic* functionality that was reported as missing as far back as 10 years ago and *nothing* has been done to fix this.

The worst part is Mozilla are clearly aware of this. An issue was opened on github and was only closed to be moved over to bugzilla where it remains open. And for some reason on bugzilla the severity is marked as N/A even though this literally means you cannot use Firefox Android on any network with a proxy

I apologize for the harsh and direct tone but I am truly astonished that no one seems to think that this is as severe as it actually is. I use Firefox because I love open source software and I hate the idea of google having a monopoly over browsers. Things like this where basic features are missing (resulting in the browser being completely unusable on certain networks) make me reconsider if this browser is even worth using. And please don't say that FoxyProxy solves all of this because the fact that basic functionality is locked behind a third party extension is unacceptable.

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.

For the past few days Firefox on Mobile has not been working with mobile data. Other installed browsers work. I am not sure what seems to be the issue.

I am running FF version 119.01, on Android 13.

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.

I used the "clash for Android" program to turn on the system proxy, only Firefox had an exception, and all other programs were able to connect to the Internet normally. Strangely, I can swipe web pages in Firefox with a VPN, but not with Clash. The Android version I am using is 118.2.0, the system is oneui 5.1, Android 13. The phone is not rooted, I would like to know how to fix this problem with clash.

I can no longer get to the login page for my spybubble account . I get this message every time I try to

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??

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.

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.

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.

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.
