I have been using Firefox on my iPhone for years without problems. But for about a week now if I’m on data it can’t load any websites, a message appears saying it cannot connect to server. It works fine when I’m on WiFi.

i'm sure this has been asked many times, but i can't determine how to get this link viewed correctly in firefox but opens no problem on safari:

https://www.mlssoccer.com/mlsnext/tournaments/cup/qualifiers/standings/florida_regional

i have tried to go through the options available in the input field but don't see anything that allows me to say it's ok to open. there are other links with similar results and some i can resolve others i have no clue where to look further.

Ever since the update to iOS 26.4, I’m unable to access insecure or untrusted sites. I first noticed this when trying to get to some devices on my local network, but I tested an insecure site on the internet and it happened there too. What’s weird is that Safari does still let me access these sites after proceeding through the warning as expected (albeit with a refresh which is new, maybe a bug), but Firefox will just load for a split second and stop.

Just a quick rundown of some additional info:

- Firefox has been updated to the latest version, 149.0. - The local sites are ones I’ve previously given trust to - Firefox has local network access enabled in settings - This also occurs on iPadOS 26.4 - I did some more testing while writing this and it seems intermittent? For example, I have a server with several docker containers, and I can access some of them if I put the port in with the IP but others I can’t. I also have a device that I can get to via hostname but not IP. - I also downloaded Chrome to test things there and I get the “this connection isn’t private” message with the option to proceed anyway, and I’m able to access these sites there.

I’m not sure if this is something on Firefox’s end, Apple’s end, or a combination of the two. Either way, I wanted to see if there was anyone else experiencing this issue or if it’s just me.

Do not know how to explain but since ios26 up date ipad tab bar and screen ( notification at top ) and ipad bar collide and makes using it impossible as cannot access tabs see screen shot . Dont know how to explain. I have to quit go back in works for a few then does it again. Will only let me post the facebook example. Have call into apple just wondering if firefox is not working with new update. Srry for the lousy explanation

Need help please to fix this problem: Firefox does not open QR codes on my iPhone. On my phone, the toggle for Scan QR codes is turned on. I open the camera on my phone, point it to a QR code on my laptop screen, Firefox on my phone opens in a new screen -- but nothing happens. What is missing? Thanks for helping me.

Links on iPhone open in new tab that has to be closed rather than return using back navigation. I saw bug reports about this, but they affect iPad users with keyboard while I have vanilla iPhone. The same happens on Vivaldi so IMHO this is underlying iOS browser engine bug affecting all custom browsers.

Currently whenever I try to pay for something via PayPal on mobile Firefox, it opens an about:blank page and never redirects. I am able to pay using PayPal just find when accessing via a PC. Unsure if there’s anything going wrong my end or if this is an issue Firefox mobile currently has. Having this issue on IOS on version 144.1

Firefox v140 on iPad, iOS v18.x.x

Missing Home Page icon on Firefox web pages after forced update to v140. Not good!!!

Is there any way to restore the Home Page icon (house) or restore a previous version of Firefox?'

My Firefox browser works just fine, and the "about" tab says it is up to date with ESR, but Chase.com won't let me log in, saying I need ESR. If I already have it, what gives?

1週間ほど前にFirefoxがアップデートされたのか、インターフェースの見た目が変わりました。 それ以降、検索バーに文字を入力すると、入力中のテキストの背景に濃いグレーの色が表示されるようになり、文字（黒）が非常に見づらくなって困っています。

この背景色の変更は、Firefoxの設定で元に戻したり、調整したりすることは可能でしょうか？ あるいは、ユーザースタイルシートなどを使う必要があるのでしょうか。

使用環境： ・Firefox バージョン：139.2 ・OS：iOS 18.5

検索するたびにすごくストレスなので、アドバイスいただけますと幸いです。ただ複雑な設定などは自分には対応できそうにないので、解決できなそうならブラウザを変更するしかないと思っています。 どうぞよろしくお願いいたします。

Hiya, The latest firefox update for iOS 26 on mobile added a new feature, or at least a new prompt for an existing feature, with moving the address bar to either the top or the bottom, however this does not appear to apply to the sideways view option, and the address bar is only at the top regardless of which setting is used. Is this a bug?

Also it appears that the auto-hide behaviour takes more scrolling before it engages. Is there a setting to adjust this? If not I would like to request a setting to adjust this on mobile be added as I would prefer it be almost instant in both hide and unhide if possible. Many thanks!

After the latest update to Firefox for iOS, I can't open pages with an untrusted SSL certificate. It's a blank page. There's no threat prompt that I can accept to proceed (as before). I use Firefox for iOS primarily to log in to Ubiquiti devices on the local network (address: 192.168.x.x). Everything worked fine until recently. Now it doesn't. I cleared the browser cache, disabled security, and that didn't help. I uninstalled and reinstalled the browser, and that didn't help either. Other iOS browsers (e.g., Brave and Safari) work fine—the untrusted certificate prompt appears, and after accepting the threat, the login screen appears. Please help.

Hi! For 2 weeks now I cannot permanently set a default search engine. I've always set Brave as my default search engine in settings. All of a sudden this was changed to DuckDuckGo by Firefox without my knowledge. I can change it back to Brave, but as soon as Firefox is cleared from memory it will revert to DuckDuckGo. Is anyone else experiencing this behavior? As it is now I cannot use Firefox when I always need to change the settings before using it.

I have been unable to sign into my Amazon account on Firefox for quite some time. I can open the account on Chrome or Microsoft Edge. I have tried everything recommended by Googling the problem such as clearing cache, etc. but nothing has worked . Firefox has been my default browser but I'm thinking I should change to another browser. Any Suggestions would be helpful.

I'm a little disappointed that I will have to use a different browser to stream with Xfinity. I have asked for help to determine what could cause connectivity issues, but obviously it's not a big enough issue. Too bad, I kind of liked Firefox.

Hi.

I like to switch tabs in the iOS app with some gesture. Is that possible?

The only thing I found in the documentation is that some keybinding exists, but I do not have a keyboard attached to my phone.

I also found some old request and some Reddit posts that swiping the address bar would do the trick. This did not work for me.

I am hoping for something like a three finger swipe anywhere, but have not spent much thought on a perfect UI integration.

I love to learn how to make switching TABs by gesture work.

Thank you for your work! Oliver
