Firefox vir iOS Community Forum

Recently (past few weeks) I’ve found Firefox on my iPhone (iOS 26.5.2) has stopped loading. I’ll open the app and it won’t load the page at all. It also doesn’t let me reload the page, add tabs, or close tabs. Occasionally it will fix if I click a link from an SMS or something that then opens in the app. Quitting Firefox doesn’t work, restarting my phone also doesn’t work.

Pressing and holding on an image then selecting “save image” causes Firefox to crash on iOS. I checked the permissions to photos in iOS settings. I also tried to uninstall Firefox then reinstalled, same issue. I tried clearing the cache in Firefox settings

Most of time when I open the Firefox app on my iPhone, it freezes on the homepage. I am unable to use the search bar or anything (other apps on my phone work fine, and I am able to swipe down my notifications so I pretty sure it’s the app misbehaving). I usually have to open and close the app a few times now for it to get going. I’ve tried closing all tabs, it makes no difference. I’ve also tried clearing my cache and browsing data but it didn’t help. Really inconvenient! Would appreciate any help.

Hallo Firefox Team

Ich habe ein Verbindungsproblem verursacht durch Firefox . Es ist ein Problem bei Abschluss der OSIP Registration aufgetreten nach ich mich mit den iPhone identiviziert, einem Account angelegt hatte und dieser bestätigt wurde. Leider verweigert die Seite ideas.esa.int den Externen Benutzerzugriff weil dieser verschleiert ist? Ein neuen Registrationsvorgang (unverschleiert) mit neuen Account E-mailadresse angelegt das gleiche Problem , kein Kontakt bzw. Ansprechpartner.

Mit freundlichen Grüßen Rolf Nieske

Firefox appears to be very limited compared to my past experience. Bookmark icons can’t be moved, bookmarks can’t be displayed as text, etc. I’ve looked everywhere to customize as desired, but can’t seem to get it like i want it.

Anyone know what is happening? In the past month or so trying to view websites on iPhone, even on Firefox has become impossible.

The number and size of ads has metastasized to the point they block out all content. Is this a new trend? Is it my settings?

Who is responsible for this shift — the website ad settings or the browsers? Is it Google further breaking the internet?

For the neurodiverse, it’s an accessibility issue as well as a dystopian nightmare.

Please tell me there’s a way to fight this apart from permanent reader mode. This has vastly reduced our use of the internet. Each site feels like a trap and a scam.

The ads cause anxiety as well as irritation and general thwartedness as I cannot reach the content! What are these people/bots thinking?

Thanks

Noticed that Firefox on IOS was updated about 17 hours ago, so that may explain the current issue. When I open the app on my phone, it will be on the page I was last on, but would be frozen. Cannot add a new tab. Cannot add an address to in address bar. Nothing can be done u til I force quit the app, and then reopen the app afterwards (as long as I give it a couple seconds afterwards). Didn’t have this issue the day before.

I've been using Firefox for over a decade and I'm noticing lately that a lot of sites are no longer working correctly. For the past few months, whenever I order food online, I get to the end to pay and it won't complete the transaction, I have to do the whole order again through Safari. Just yesterday, I noticed an issue on the NYTimes site. I can scroll the main page using the track pad without a problem, but when I click into an article I cannot scroll at all, I need to use an actual mouse. Again, I don't have this problem on Safari. Is there a setting that is doing this (I haven't changed anything recently and I've cleared my cache)?

I have Firefox 152.3 (73911) on iPhone with the latest iOS 26.5.2 On Firefox, web pages not showing up when switched between open apps on iPhone.

I can see web pages on Safari.

Hello.

I've found myself to rely on Firefox for some specific workflows that require sending emails that are generated automatically by a website, and I use it across multiple devices, such as Windows, macOS.

Unfortunately, when it comes to iOS, using the aforementioned website, when tapping the relevant "mailto" button, nothing happens.

Some months ago the specific website that I use, was failing to do this action on any webkit browser, but this was later patched by the developer and the flow now works correctly within Safari. This was caused by stricter enforcement of "user-initiated" actions.

Unfortunately it seems that Firefox isn't either capable of invoking the mail client, or get the data from the website properly.

Firefox Sync is not syncing bookmarks from Windows to iPhone.

The issue persists even after creating a completely new Firefox Account, creating a new Firefox profile, reinstalling Firefox, and testing on a different network.

Environment Windows 11 Firefox 153.0 (64-bit) Firefox downloaded from mozilla.org (not Microsoft Store) Firefox for iPhone (latest version) VPN disabled Windows Defender only (no third-party antivirus) Problem

Bookmarks created on the iPhone never appear on the Windows PC.

Bookmarks created on the Windows PC also never appear on the iPhone.

The iPhone currently contains more than 1,000 bookmarks.

Tabs and account sign-in appear to work normally, but bookmark synchronization does not.

Troubleshooting already performed Created a new Firefox profile. Reinstalled Firefox. Created a completely new Firefox Account. Signed out and signed back in. Reset Sync. Verified that bookmark sync is enabled. Confirmed services.sync.engine.bookmarks = true. Tested with VPN disabled. Tested using a mobile hotspot instead of the home network. Verified DNS resolution using nslookup. Verified Mozilla servers are reachable from Chrome. Confirmed Firefox DNS settings are default: network.trr.mode = 0 network.dns.disableIPv6 = false Sync log observations

The Sync log reports that bookmark changes are detected:

Sync.Engine.Bookmarks.BookmarkSyncUtils pushChanges: Processed change records: {"updated":9}

However, the log never contains a request similar to:

POST ... /storage/bookmarks

Therefore, bookmark changes appear to be detected locally but are never uploaded to the Sync server.

In different sync attempts, I have also observed intermittent network-related errors such as:

NS_ERROR_NET_RESET NS_ERROR_CONNECTION_REFUSED NS_ERROR_UNKNOWN_HOST

For example:

Failed to fetch symmetric keys. Not syncing: login returned false.

and

The lookup of the hostname failed.

However, DNS resolution and connectivity appear normal outside Firefox:

nslookup successfully resolves Mozilla Sync hosts. ping succeeds. Opening https://profile.accounts.firefox.com/v1/profile from Chrome returns the expected HTTP 401 Unauthorized response ("Bearer token not provided"), indicating the server is reachable. Additional information

Because the iPhone contains more than 1,000 bookmarks, I would also like to know whether Firefox Sync has any known limitations or issues related to synchronizing large bookmark collections.

Expected behavior

Bookmarks created on either device should synchronize to the other device.

Actual behavior

Bookmark changes are detected locally but never uploaded, and no bookmark synchronization occurs in either direction.

I would appreciate any guidance on additional diagnostics or whether this could be a Firefox Sync bug.

When using the native translation tool in Firefox for iOS to translate an English page (specifically tested on Wikipedia) into Portuguese, the translation is incomplete and inconsistent.

This behavior mostly occurs inside collapsible sections (the topics that expand and collapse when you tap the arrow icon). The translation failure is not just on a paragraph-by-paragraph basis; it often occurs partially within the same section, where some sentences are successfully translated while others right next to them remain entirely in English.

Ios 18.7.8(22H352) Firefox 152.4(74210)

Steps to reproduce:

   Open Firefox on iOS.

   Navigate to an English Wikipedia article (mobile view, which uses collapsible sections).

   Trigger the built-in Firefox translator to translate the page to Portuguese.

   Expand one of the sections using the dropdown arrow.

Expected result:

The entire text, including all sentences and paragraphs inside the expanded sections, should be fully translated into Portuguese.

Actual result:

A broken, partially translated layout where some sentences/paragraphs are translated, but others immediately below (or within the same block) remain in the original English.

(Note: Please attach your screenshot showing the open section with the arrow and the mix of Portuguese and English text).

Exact same problem as reported in 2025: "My Firefox on iPhone has a malware that pops up a box urging me to call a phone number (which I won’t do) about a payment. It has Cancel and Ok buttons, both of which trigger another box from the dialer containing the same phone number. I cannot get to the FF settings or escape from that page because the pop ups immediately come back and reload the page. " Only difference from OP is the server url is recipes33-16045505ea03 . herokuapp . com

The posted solution was to reset history, but I can't get to that or any other controls or the url bar - canceling just reloads the page before I can initiate any action. A similar post suggested installing Malwarebytes but that requires enabling extensions which, again, I can't get to.

Right now Firefox is bricked by this and I have to use Safari :-(
