When accessing Outlook (https://outlook.office.com) using Firefox ESR version 128.9.0 and attempting to download a file attached to an email, the string 'UTF-8' is automatically inserted at the beginning of the file name, which is causing issues. This phenomenon does not occur with other browsers such as Edge or Chrome.

Is there a way to solve this problem?

ATT.NET is blocking my access to ATT/Yahoo email from my ATT.net account using Firefox ''but not using Chrome?'' I have stopped all tracking and cookie blocking

Whenever I open up PDFs within the Firefox browser, they have a black background and the text and images do not appear. I can copy the text and images out of the pdf and into a word document and it works out fine. Also opening it up on other applications works out fine. Attached is what happens when I open up a known working pdf in Firefox. The browser version is the current version, 135.0.

Up until 2 days ago, I had no issues accessing my yahoo email accounts (sbcglobal.net through At&T) I had done nothing different re settings. I rebooted my modem and my computer several times. I deleted old history which I do several times a week anyway. I called AT&T support team but they just suggested logging on to another browser. So I tried Edge and was able to access the emails successfully. I even "refreshed" Firefox and nothing changed except I had to replace several quick links. I checked for updates and discovered my Firefox browser is up to date. My Android cell phone has no issues with the emails. I have one on Firefox browser and one with Chrome on my cell phone and no issues with either one. I have been using the same log in link for many years. I even explored the new way to log in called "Currently.com" for yahoo mail. Still won't work on Firefox. But it does work on Edge. I would prefer to continue using Firefox for browser but need to use Edge til I figure this out. Any suggestions would be greatly appreciated. (BTW wifi IS on and the connection for everything else works fine.

I am trying to access certain HTTPS websites and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chromium.

Here's what I've tried (none of these works):

• DNS over HTTPS turned off
• Uninstall all add-ons
• Reinstall Firefox
• Create new profile and set it as default
• Delete/rename certs.db in the Firefox profiles folder.

The only fix that works is to use Troubleshoot Mode every time I visit these websites which is not practical. Any ideas on what could be the problem?

I don't know if this is relevant but one of the websites that does not work is https://alexan.com.ph/

A few days ago I changed to a new computer.

On my old Windows 11 computer in Firefox I could sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, edit my posts, post new posts and see the sign out option.

But on my new Windows 11 computer in Firefox I can sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, but I can't edit my posts. I am signed in but Firefox doesn't show the sign out option.

Whereas on my new computer in Chrome I can sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, edit my posts, post new posts, and see the sign out option. As always.

In Firefox it says there is something wrong with my [edited] @gmail account and to refresh it or change to another account. I don't now how to refresh it and changing to another Gmail won't work. But it lets me in to my blog's New Posts page!

How can I in Firefox on my new computer edit my posts and see the sign out option, as before and as always in Chrome?

I have Firefox's New Tab set as my home page, since I'm choosing to divorce myself from political doomscrolling for the next four years. The New Tab page is perfect for having frequently visited sites at the top, Pocket stories I can curate in the middle, and what used to be a history of articles and sites I've read most recently in "Recent Activity" along the bottom. Within the last few days, "Recent Activity" has been blank, and will no longer keep track of articles I've recently read. I've tried clearing the browser history and cookies, and it came back for a moment, but quickly went back to being blank. And the major downside to clearing the browser is that my four rows of most frequently visited sites gets wiped clean also, and I have to spend time getting them back on the list. I do not have Firefox set to automatically clear history upon closing it. I've tried turning "Recent Activity" off and on with the page's Settings (cog in the bottom right corner). I'd really like to have this back, as it can help me find recently read content (especially Pocket content) easier than wading through the History log. Any help would be appreciated.

Hello,

I dislike the Group Tabs feature. So many times I've accidentally created a Group Tab and then had to figure out how to un-group them.

I've tried to change the value of the "browser.tabs.groups.enabled" preference to false, but it doesn't stick; after restarting, the value is always back to "true".

What’s up with this?

Thanks, Andre’a

bold text Firefox is demanding that I sign in to my Amazon account with a passkey on my phone. I don't have a passkey on my phone. I cannot cancel the request!

Due to relevant policy and legal reasons, the Chinese version of Firefox has been used https://accounts.firefox.com.cn/ As a login account URL, it is also used in the international version https://accounts.firefox.com As login URLs, the two accounts are not interconnected. After recently upgrading to a new computer and downloading Firefox again, I am unable to use the synchronization function https://accounts.firefox.com.cn/ Login to the account, the specific manifestation is to enter the correct password when logging in, and it will continue to display 'processing'. But by directly entering the above website address, you can log in to your account normally. I now need a solution to the synchronization issue by moving bookmarks, plugins, themes, and synchronized tabs from my previous Firefox computer to my new computer.

由于相关政策法方面原因，中国版的firefox使用了https://accounts.firefox.com.cn/作为登陆账户网址，同时而国际版使用https://accounts.firefox.com作为登陆网址，两者账户不互通。

最近换了新的电脑以后，重新下载firefox，使用同步功能时，无法使用https://accounts.firefox.com.cn/登陆账户，具体表现是登陆时输入正确密码后登陆，一直显示处理中。但是直接输入上述网址，可以正常登陆账户。

我现在需要可以解决同步问题的方法，将我原来电脑中firefox中的书签，插件，主题以及同步的标签页移动到新电脑中。

Bookmarks have been intermittently disappearing for weeks but I could always see the blue star when I visited favorite sites that I use upon starting my day that I had bookmarked. This morning all bookmarks were missing. I tried clearing cache which had worked to restore some bookmarks that were missing. Now everything is gone and I cannot recover them. There is an error that appears when I open Firefox re: bookmarks and I followed the steps but it did not work. I really need my bookmarks to do all the things I need to do, like everyone else, including medical information websites. I hope you all can get this figured out as it has been a problem for a month for me, on a PC. I know my favorites are stored somewhere on this computer but I cannot make them populate. If someone would like to take control of my computer and fix it for me, I would happy to let you do that. I have run sfc/scannow and chkdsk/f as well as a total virus scan with Norton. I have restarted my computer several times as well as done a complete shutdown several times.

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

I don't know whether this happened after an update - there was one a few days ago, but I only realised this morning, after switching on the computer, that all my bookmarks are missing. The toolbar is there, empty, only reading "For quick access, place your bookmarks here on the bookmarks toolbar"... I wish! I tried to restore the bookmarks - but it seems there is no backup to restore at all. Then I tried to check my profiles, but there is only the one currently in use. Then I tried to move a tab to the bookmarks toolbar - and nothing happened. Then I began to panic: toolbar apart, we're speaking about years of bookmarks, most of them related to my research for my books... All the advice in the support seems to point towards profiles and backups, but, as I said, it's clearly not my case... Please, please, please: help!

I can no longer access my local TrueNAS server nor router via Firefox. My current version is 133.0.3. Safari has no trouble. Firefox gives no warning, no Advanced button, no option to bypass security. All I get is: "Unable to connect An error occurred during a connection to 192.168.0.102.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."

I have tried so many settings, troubleshootings, workarounds, I can't begin to list them. It happens in troubleshooting mode. I have created SSL certificates on the server many different ways to no avail. I'm thinking I will have to abandon Firefox with it's obscure, no-way-through security. But I wanted to ask for help first. Please help.

I run a Synology DSM server on my local network. The website page to load locally inside my LAN is along the lines of 127.0.0.1:1001.

MacOSX 15.0.1 FireFox(FF) 132.0 (aarch64)

Previously accessing the DSM via the local IP address worked fine with no problems. Now, following one of the last couple of FF updates, I get an "unable to connect" message.

I also have a domain that routes to my local server and I can still access the DSM via the internet http address through FF. So I know that DSM is running fine and I have verified the settings within DSM.

I can load the DSM via the local IP in both Safari and Chrome. Only FF says it's unable to connect. So that shows that my DSM settings are fine and the page is available and loads in Safari and Chrome via the local IP.

I searched the forum and found similar postings, but not quite the same issue as mine. I deleted the cache & cookies/site data. I ensured the Proxy mode in FF is set to "No Proxy". I do not have any extensions running or themes.

I am at a complete loss at what setting in FF I need to change to restore this functionality.

Thanks, Matt

I got an email supposedly from breach-alerts@mozilla.com that claims there are currently 3 data breaches and has this link to resolve: https://blrv1ly5.r.us-west-2.awstrack.me/L0/https:%2F%2Fmonitor.mozilla.org%2Fuser%2Fdashboard%2Faction-needed%3Futm_source=monitor-product%26utm_medium=product-email%26utm_campaign=monthly-report-free-us-scan-no-exp-yes-breach-resolved-no%26utm_content=resolve-exposures-us/1/01010195ceba1024-6e3f74fe-119a-4e2e-9033-398671a830d9-000000/DDeGOTLjROOXCCk2fJvXJbdefc4=419

This seems like a phishing email, is it legit? Should I find another browser?

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

I am a bit confused about how to keep updating FF on my Windows 7 PC, given that after March my current version (115.17.0esr) may not work as intended. Until now I've always updated manually by downloading a small 343KB installer file that updated FF without changing any of my settings, logins and bookmarks. Hoping to simplify updating, today I set updates to "Automatically install updates (recommended)" with sub-option "When Firefox is not running". But just now a FF notification informed me it was unable to update automatically and provided a link to https://www.mozilla.org/en-GB/firefox/enterprise/?reason=manual-update. From the dropdown there I chose "Windows 64-bit" > "Firefox Extended Support Release (ESR)". The download is a 64MB file.

Since this seems to be a new installation and not a simple update, can I be sure it won't overwrite my current version and leave me without settings, logins and bookmarks?

Greetings. Please help.

After Win11 update, Firefox started to just show "Gah. Your tab just crashed." I've uninstalled multiple times from MS Store and also direct from website. No luck. Safe mode works fine. My normal mode does not work even when all the addons, etc are disable. I'm a simple user with no customisations of the FF browser.

Tried new profiles, untick performance, etc.

I've even tried restore win11 update to an earlier date. Same result.

Other browsers work fine but I want to support Mozilla. I'm at the point of switching to another.
