Running Firefox 149.0.2 (64-bit) on MacBook Pro (16-inch, 2019) with Catalina (10.15.9).

I was in the process of updating a non-profit's website and had opened the html file on my computer. I noticed that the "y" (lower case) was missing from the days of the week. I checked the RUNNING website and saw the same thing. Checked he same website with Safari and the "y" suddenly appeared. Okay, so I then tried to add another "y" somewhere else on that page and ... nothing, so on a whim I added a "Y" to my Mac's file and guess what? It upper case Y displayed. Also noticed that on some web pages instead of showing me the characters in some words, it substitutes "ddddddd" for some words. What's up?

Mozilla has disabled the 1Password extension. I've used this version of 1Password extension for years without issue so do not share Mozilla concerns. How do I override the disabling to continue using 1Password as the risk is acceptable to me? It is more important to me to be able to use 1Passsword than Mozilla, so I'll switch to another browser if Mozilla won't let me make my own risk determination.

My K-9 in Android suddenly stopped to work a couple of days ago. The server asks for autentification. I haven't changed anything. I've uninstalled and reistalled the app and restarted my phone a Samsung S22 ultra several times. The app is recognating some settings automatically but it doesn't accept my old password with 16 letters in a group of four with highfens in between. What shall I do, please? Something wrong with the server? The version of the app is 17.0 updated March 16th 2026.

Hi there.

Since quite a while Firefox is trying to enhance our browsing security by "upgrading" connections from "http" to "https." This may generally be a good idea, but it is literally driving me crazy at the moment because it also does so for "internal" sites I host within my LAN (such as my "Home Assistant" instance or a Zigbee coordinator, accessible via its own hostname and web UI). However, these connections will fail, because I don't have certificates for my internal hosts, and thus there is no "https" listener. :-(

(I use my own subdomain "<host>.city.internal.example.org" internally, so Firefox may be confused?)

I feel this behavior has become "more aggressive" within the last few days, so maybe it is due to a Firefox update?

Is there a bullet-proof way to prevent Firefox from doing so?

I've already set the below options to false: - dom.security.https_first - dom.security.https_first_for_custom_ports - dom.security.https_first_for_local_addresses - dom.security.https_first_for_unknown_suffixes - dom.security.https_first_pbm - dom.security.https_first_schemeless - dom.security.https_only_mode - dom.security.https_only_mode.upgrade_local - dom.security.https_only_mode_pbm

Help, please!

I'm close to abandoning Firefox in favor of a different browser, because at the moment it's close to being unusable for me anymore... :-(

Kind regards,

Ralf

My computer has not worked for nine months.

I've been looking at my e-mail on my phone (not in Thunderbird for Android, which pretended to send my messages but didn't). I want it on my computer.

I didn't want to do that right away, but it looks like Thunderbird started doing that automatically when I launched it. It successfully got my small account, of course, but not my big one.

It's been stuck on this for more than 12 hours. (See image. My apologies, I've forgotten how to embed them.)

Is it safe to shut the process down? Whether it is or isn't, what do I do next?

My computer is a MacBook Pro (13-inch, Mid 2012), running OS X.15 (Catalina), with Thunderbird 140.0.1esr (64-bit). The process started before I could upgrade to 149esr.

Thank you for any help you can give me!

UPDATE, 4/11, 8PM EDT: No change. . . .

When opening the "Show all history" window (command Y) the text is garbled. I have checked the font book and there are no duplicated and I have validated all fonts. I have tried using the troubleshoot mode and occasionally the text is rendered correctly but mostly it has no effect. There is no other location in the browser where the text is garbled. I have tried changing the text in the advanced settings and both performance settings are disabled.

When using the built-in Firefox AI sidebar and clicking the "Summarize page" button, I consistently get the error: "431 Request Header Fields Too Large" from chatgpt.com.

Cookies were cleared multiple times Extensions (including AdGuard) were disabled The issue persists

Previously, changing a privacy setting temporarily helped: switching from "block all cross-site cookies" to "block cross-site tracking cookies and isolate other cross-site cookies". After that, the feature started working.

However, after restarting the browser today, the issue returned, and changing this setting no longer helps.

I would also like to note that currently there is no way to disable or hide the "Summarize page" button, even though I did not need it initially. I tried to configure things so it would work properly, but was unable to do so.

Steps to reproduce:

Open any webpage Open the Firefox AI sidebar Click "Summarize page" Observe error 431

Expected behavior: Page summary should be generated successfully.

Actual behavior: The request fails with HTTP 431 error.

I'm having problems with AOL ad blockers. The program says that I have ad blocker plus turned on in my Firefox extensions. I turned everything off in the exension menu and still have the same issue.

My user experience on Firefox is being severely impacted and is making me angry. I watch the updates calendar they are once a month. So why can i not go a whole week it seems with a necessary Firefox update to my browser that impacts the performance of websites. I like to have multiple tabs open over a week or more. I don't want to close and reopen my tabs every time I want to use my computer. SO WHY are there SO many updates. It's seriously making me want to uninstall your browser and I have been using Firefox on multiple devices for years. More than 20 years now. It's seriously ridiculous to have a major update every week or even every other week where I have to shut down and save my work on ALL of my tabs just to update Firefox. I have never remember history and I am going to uninstall and reinstall from even greater security because I have serious concerns about the amount of data that big tech companies share with 3rd Parties and the government. I am an honest American citizen and I HATE being surveilled and having my private life sold to the highest bidder. But even though. the safety of your browser is a positive feature it becomes very difficult to WANT to use Firefox when my workflow is CONSTANTLY interrupted.

Seriously, You JUST updated on the 23rd/24th and now just two weeks later there's already ANOTHER update. And who even knows when that one dropped. I only checked it because sites were acting up. And EVERY TIME a site acts up it's because of an update. You have interfered with my user experience with Youtube, and Multiple Streaming Services, and Multiple Chat bots. It's thoroughly dis-satisfactory and disruptive, and ANNOYING. I want a tool that protects me while I am on the web. I do NOT want a tool that ruins my internet experience every week.

Hi there. I'm looking for a shortcut that takes me from the folderlist pane to the message pane and the first new message, when I'm on the inbox folder. The tab is not good. It moves between to many fields/options.

Hi,

Microsoft and Google are part of Anthropic's Project Glasswing but Mozilla is not. I am concerned about Firefox security if Mozilla in not being included. What is your plan to participate? Do I need to switch browsers in the meantime? Please advise. Thanks.
