I had an issue where my browser disappeared. Here are specifics for my installation.

Name Firefox Version 142.0.1 Build ID 20250827004350 Distribution ID raspberrypios User Agent Mozilla/5.0 (X11; Linux x86_64; rv:142.0) Gecko/20100101 Firefox/142.0 OS Linux 6.12.62+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.62-1+rpt1~bookworm (2026-01-19)

I relaunched and then restored previous session. After that, I searched open tabs, but when I selected a tab that was reported to be opened,  it was not restored. I went to troubleshooting mode and it worked fine suggesting some issue with an extension.  What, if any logs could I capture to help debug? thanks

My bookmarks do not sync between my Android( Samsung 22 Ultra) and my Desktop( Windows). I show this issue as when I would delete and update bookmarks on my mobile. They did not update on my computer. I have tried signing out on my computer, which wiped out the bookmarks and other saved attributes. Then signing back in. This did not work. My bookmarks menu is bare. Even though in my account I have both my mobile and computer accounts connected. What can I do to fix this?

Some background, the bookmarks and other saved attributes where from chrome, I transferred them over.

I have been trying for WEEKS NOW to sign into my bank! The bank can use a TEMPORARY password to access my account but once that's over, when I try to log into my bank I STILL CANNOT LOG IN!!!!!!!!!! WTF has happend to Firefox after that last "update" what ever it was they changed, made it IMPOSSIBLE for me to log into my BANK. The problem is NOT the bank it's FIREFOX & FIREFOX NEEDS TO FIX THIS CONNECTIVITY PROBLEM SOON IF NOT SOONER!

I am trying to set up a new computer. I have customized the homepage and new windows to a preferred page, however I cannot customize the new tab settings. The only options for a new tab are either Firefox homepage or blank page. I am trying to find a way to have my preferred homepage open when I open a new tab.

I am a Dropbox user. I have until recently been almost strictly a Google Chrome user. The PDF seamless behavior I have been seeing in Chrome is like this: 1. If I click on a search engine result for a PDF, I see the PDF opened in the browser. 2. If I click on Download at Dropbox, the PDF is downloaded to my PC.

On installing Firefox, the behavior I saw was like this: Whether I clicked on a search engine result or Download at Dropbox, I saw the PDF opened in my browser.

When I changed the Action for Portable Document Format (PDF) (application/pdf) and Portable Document Format (PDF) (application/binary)to "Save File", the PDF downloaded to my PC. But so did search engine links.

I seem to have fixed the issue by making my settings like this: 1. Action for Portable Document Format (PDF) (application/binary) to "Save File" 2. Action for Portable Document Format (PDF) (application/pdf) to "Open in Firefox"

Fingers crossed. ??? I was wondering why it wasn't set up this way on installation.

Hello.

My Firefox browser is missing the close button from the top bar. Minimize and Maximize buttons are present.

This is happening on Fedora 42 With Gnome.

I believe I don´t have any custom theme or user css or extension that could cause this.

Also because, it seems to be hapenning not only in Firefox itself, but also in Firefox based browsers, like Tor Browser.

Anyone has any idea what is hapenning?

Thank you.

I'll be honest, I have strong ethical objections to "generative artificial intelligence" (genAI) on a range of issues, and I have seen no sign that the industry is capable of, let alone plans to address any of them. But I'm not here to debate genAI, I'm here because I require a work enviroment and tools that make it as easy as possible, preferably default, to avoid genAI.

I'm deeply disappointed that the Mozilla Organization has decided to add genAI to label tabs in Firefox. Even if I didn't have ethical concerns, I would still be disappointed at the bogged-down performance and genAI hallucinations that make this change categorically a downgrade.

I respect other users right to do things I find harmful, and the Organization's authority to make decisions. I treat genAI much as I treat smoking, everyone gets to make their own choices, but I have the right not to be exposed to second-hand smoke. Having genAI options default to on is like having somone blow smoke in my face, and when they can't be turned off, it is like having an acquaintence who insists on smoking in my home: I won't have them over (use their software) any more.

I'm in the process of kicking the people who smoke in my house out, and minimising my exposure to "second-hand smoke" (unwanted genAI). I've been a Mozilla user and proponent since the Organization was founded, and was a Netscape user before that, so I don't want to lose an old friend... but I am looking into other options.

saw a post that recommenced to installing K-Lite Codec Pack would help so that i could set 1440p on Twitch because the option is greyed out for me. after installing it, twitch gets hung up and never finishes loading. it loads in a private window, and on edge too. i turned off the few extensions i have but that didnt help either.

i uninstalled the codec pack but im still getting the issue.

if i hit F12 i see theres an error Loading failed for the <script> with source “https://assets.twitch.tv/assets/6411-9f5e77558af00b1acec0.js”.

thnx!

Firefox detected a potential security threat and did not continue to player.vimeo.com because this website requires a secure connection.

What can you do about it?

player.vimeo.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

I continue to get this message when clicking on a link. How do I rectify the situation?

I installed chatgpt, but I've found it more of a nuisance than a help. I've tried on-line to find out how to remove it but none of the suggestions seemed to work. I'm using the latest version of firefox on a Macbook Pro. Any ideas welcome. Charlie
