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.

Hello,

On the Firefox home page, there are shortcuts. I have pinned some of these shortcuts. When I click on a shortcut, it opens in the current tab. I would like to have the shortcut I click, open in a new tab, without having to Ctrl+click Is this possible?

Subject: Feedback: Please Show Full URLs by Default and Disable “Show Search Terms in Address Bar” by Default

Hello Mozilla Firefox Team,

I would like to suggest two changes to Firefox’s default address bar behavior that would improve transparency, usability, and user trust.

1. Show Full URL Addresses by Default

  Currently, Firefox hides parts of the URL such as “https://” and sometimes simplifies the displayed address. I believe Firefox should display the complete URL at all times by default, including:

• Protocol (`https://`)
• Full subdomains (`www`, `m`, etc.)
• Complete path when relevant

Displaying the full address helps users:

• Better verify website authenticity
• Detect phishing or deceptive domains more easily
• Understand exactly where they are navigating
• Maintain consistency with technical and professional workflows

2. Disable “Show Search Terms in the Address Bar on Results Pages” by Default

  The feature that replaces the actual search engine URL with the search query text can be confusing and reduces transparency. Many users expect the address bar to show the real URL of the page they are visiting.

I recommend disabling this feature by default because:

• It hides useful navigational information
• It makes copying/searching URLs less predictable
• It can create ambiguity about the actual site/page being viewed
• Advanced and privacy-conscious users generally prefer seeing the real URL

Users who prefer the simplified search-term display could still enable it manually in settings.

Firefox has traditionally been a browser focused on user control, openness, and transparency. These changes would align well with those principles.

Thank you for your work on Firefox and for considering this feedback.

Hey there since a week when I brows with Firefox on Windows desktop the RAM uses jumped from around 60% spiked to 92-95% RAM and that changed just come a long a week ago. If change brows like Chrome different story, back down at 65. So you can also see a massive number on Firefox system running.

Question: Whats the reason for the change? What happend?

Best, Janosch

I'm using TB 150.0.2 on a Mac with the latest update of MacOS.

I just deleted all of my archived emails, thinking it was stuff that I had sent to trash. I.e. I deleted all archives, then emptied trash. Only after I did that did I realize that I had deleted things I want to save.

I'm pretty sure there's no way to undo emptying the trash, but I use Time Machine to back up. If I open time machine and go to the most recent back-up, I should be able to get everything back, right?

What folder (or folders) should I restore from a Time Machine back-up?

Hello,

I have been testing all browsers I use (Firefox, Chrome, Edge) on Cloudflare Post-Quantum Key Agreement to verify PQC support. They all support the X25519MLKEM768 hybrid scheme (i.e. Cloudflare web page returns "You are using X25519MLKEM768 which is post-quantum secure").

The issue: When I run the test in Firefox multiple times by doing repeated hard refreshes (Ctrl+Shift+R), quite often the result is "You are using X25519 which is not post-quantum secure". Sometimes the very first run after opening Firefox gives the X25519 (failing) result. "Often" varies. Sometimes it's around 10 fails out of 50 tests, other times it's 1 out of 50. It seems random.

I have read that sometimes networking equipment or even ISPs can be the cause of PQC requests falling back to non-PQC due to the long keys in PQC, but I do not see this intermittent issue with Chrome or Edge on the same computer/network/ISP as Firefox. I have not seen a single failure so far on those two browsers. The only variable I am aware of is the web browser.

I also tried connecting to a cellular hotspot as well as disabling my Norton 360 firewall and the results are the same as above.

Looking for help to resolve this issue. Thanks.

I keep my mail (both sent and received) in local mail folders. My server is gmail, and sent mail is put in gmail's sent folder by default. Every few months, I copy those messages to a local folder, and after I back them up, I delete the server copy.

What to my dismay, I discovered today that only the message headers, and not the messages were present in the local folder, though they had been when downloaded. Looking at the file sizes, I found the sent file to be 0 Kb, and sent.msf 255 Kb, when sent should have been around 60 Kb long.

I have been able to restore the messages from backup (whew!), but I have no idea how then sent file was wiped out. I know I did not do it.

Has anyone else had this happen? Is there a preventive measure I should take?

Has anyone found possibly a fix in about config section to fix the bug where Firefox doesn't load titles correctly in tabs? Before it wasn't so bad when tablets didn't have tab bar. Now that tables do have this feature, it would be great to fix this long standing issue. Using Firefox can be an eyesore sometimes seeing this on almost half or more of my tabs.

Image as an example. It loads this way everytime on a link off ESPN. You can get it to display correctly if you refresh the page.

I have two desktop computers. both were fine. Now when I try to access a site i have gone to innumerable times it says "Blocked access". I can still get to the site on the other computer, but it is annoying to have to hop back & forth. I looked at the settings page, but I have no idea what I need to change to regain access.

I use Thunderbird and received a message about an update which I allowed. I went to another app and when I checked Thunderbird all of my data is gone. The only folder Mozilla Thunderbird folder reads: tobedeleted. It is empty. All of the data is gone. Is there a way to retrieve it? PD - [edited from public] @gmail.com. My desktop runs Windows 10 only.

I need to stop google from automatically searching in the address bar so I can use about.config.

No help has worked from the web. Commands suggested by users don't exist or they use circular logic. In other words I can't go to about.config and make changes because I can't get to about.config because google searches it. I have turned off everything and nothing gets rid of the google search. I can go to other searches but that doesn't help.
