After the latest update, when I move a tab to the start of the line, it shrinks down to something unreadable. Before, it stayed the same size, with tabs all being the same size as each other, that size being dependent on how many tabs were open ONLY. How do I turn off this "Feature" ? I liked it the old way. I don't even know exactly what to look up to try to fix it.

I also hated tab groups, with my tabs suddenly moving around on me. I hate having to do research and maintenance every time I get an update. If this keeps happening, I may just stop updating or go to Chrome or something.

For past few weeks, Whenever I try to update FFX on windows 11, it fails. It takes me to another screen and tells me to download Firefox. When I try to download it , it aborts with this message.

"download.mozilla.org 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."

To download Firefox with new version I have to use another browser but no choice. Then with new version of Firefox, I have faced the same issue of update and used same approach to update firefox to a newer version.

This error appears for some google sites as well but the same occurring for firefox download site itself is not understood.

I have been logged out of my Firefox account and logged out of every single website, as well as having all my passwords and logins removed on Firefox and only one profile shows up on the profile page. Please help me, Thanks.

Since yesterday, I have not been able to add new bookmarks. I want to add two new ones. (I can update or delete bookmarks.) I have read and tried the solution article (https://support.mozilla.org/en-US/kb/cant-add-change-or-save-bookmarks), but the fix did not work for me. I am using Windows 11 Pro (fully updated) and Firefox 143.0.1 (64-bit). By the way, Brave is my secondary browser. I can add the two new bookmarks in it without problems. Could someone provide a solution other than the one in the article that I have cited? Again, that solution did not work for me. Thank you.

I have an extension in Firefox that automatically opens with Firefox opens. For security, how can I set it so this extension requires me to enter my password when I use it in Firefox?

Sometimes when I sign in on Microsoft Outlook's email portal - a multistep process requiring authentication on one's phone - it says: "Hang on a minute while we sign you out" and then boots me, forcing me to sign in again. For awhile this was happening only occasionally, and the workaround was to delete all cookies for Microsoft online and Office. But now this is happening more frequently, and sometimes it happens immediately after deleting the cookies. In effect, Outlook on Firefox creates cookies that then prevent it from working. And it doesn't matter whether you say yes or no to "Stay signed in?" at the end of the sign-in process.

I reached out to Microsoft tech support, and they basically said this is a Firefox issue because it doesn't happen on Chrome or Edge.

Anyone else encounter this?

When opening multiple links from a spreadsheet, FF focuses on each one before opening the next, meaning each video will begin playing, rather than waiting until I click on it. Is there anyway to make this function like chrome, where only the final tab is focused on and the rest do not play, or maybe only stay focused on the spreadsheet tab? Blocking autoplay will work, but it means I have to click to begin playing every video, which I don't want. I also already have "When you open a link, image or media in a new tab, switch to it immediately" unchecked.

I have to resort to using Chrome (yuck) when using Fedex.com. Please fix issues with Firefox and Fedex.com (very, very slow loading) thank you

WhatsApp and G messages won't stay fixed anymore, which is very inconvenient because you have to link them again every time the Windows computer closes. Have tried to put them in the Multi account container, but that does not help. Is there another way to install these two programs and let them remain fix, as they used to be....?

Thank you for your help. Pedro Lenguazco-Garcia.

Gentile Team Mozilla, vi scrivo per sottoporvi una proposta che ritengo molto importante per migliorare l’accessibilità e l’inclusione digitale: l’implementazione della funzione “sottotitoli in tempo reale” direttamente nel browser Firefox. Questa funzione, già presente in Google Chrome, permette di generare automaticamente sottotitoli per qualsiasi contenuto audio o video riprodotto nel browser, indipendentemente dalla piattaforma o dal servizio di origine. Sarebbe quindi estremamente utile per tutte le persone sorde o con difficoltà uditive, ma anche per chi vive in contesti dove l’audio non è sempre disponibile o utilizzabile. Introdurre i sottotitoli in tempo reale su Firefox rappresenterebbe un passo decisivo verso l’accessibilità universale, garantendo a milioni di utenti la possibilità di fruire dei contenuti online senza barriere. Una funzionalità simile non solo rafforzerebbe la missione di Mozilla per un web aperto e inclusivo, ma darebbe anche un segnale concreto di attenzione alle esigenze reali delle persone. Vi ringrazio per l’attenzione e spero che questa proposta possa essere presa in considerazione per i futuri sviluppi di Firefox. Cordiali saluti.

Dear Mozilla Team, I am writing to propose an important feature that would greatly improve accessibility and digital inclusion in Firefox: the implementation of real-time captions directly in the browser. This feature, already available in Google Chrome, automatically generates subtitles for any audio or video content played within the browser, regardless of the platform or service. It would therefore be extremely valuable not only for deaf or hard-of-hearing users, but also for anyone in situations where audio cannot be played or easily understood. Introducing real-time captions in Firefox would represent a major step toward universal accessibility, ensuring that millions of users can enjoy online content without barriers. Such a feature would not only strengthen Mozilla’s mission for an open and inclusive web, but also demonstrate a tangible commitment to meeting real user needs. Thank you for your attention, and I hope this proposal can be considered for future versions of Firefox. Sincerely.

I'm a developer of a web portal for a german energy supplier based on HCL Domino. The login which uses AJAX/XHR and Dojo worked for the last 8 years and until Firefox 142. But with FF 143 it's impossible to login to the user acount. I can't recognize any error in the dev tools, The request returns status 200.

Has anything changed from 142 to 143 concerning this handling?

Thanks in advance :-)

I have the current version of Firefox browser. Every time I clear the browsing history, I am being logged out of my Google and Microsoft accounts, which is forcing me to go through the tedious 2-step verification process to log back in. This was not occuring before. Please fix this annoying and time consuming bug!

Dear programmers! Firefox has been buggy since at least mid-May! You can't upload videos to Youtube with it! The upload stops at zero percent and doesn't move any further! The problem started with version 138, and it's currently the same with version 141.0.3! My operating system is Windows 10 / 64 bit. I was previously advised to delete cookies, but that didn't work either. Uploading videos works with other browsers. Sometimes, you can't even post a picture attached to a comment on Facebook. I was able to do that with another browser. The video upload error occurred earlier, with version 131! It was fixed shortly after that! I would like this to happen again! It's very annoying that this error has been around for months and hasn't been fixed!

======================================

THE ISSUE: When opening Firefox, (Attachment #1 - below) appears. Seems to have nothing to do with any reality . . . as when I check in SETTINGS (Attachment #2 - below). 1. So, who's telling the truth? 2. How do I stop the popup (Attachment #1) from making it's nagging, inaccurate appearance?

Thank you / Nels

I'm used to use the sidebar history to open previous links for a variety of reasons. You used to be able to click or middle mouse click the links to open the tab in the current or a new tab. But it seem now i can only left click the links and it opens them in a new tab regardless. Right clicking only allows you to open the link in a new tab or a new (private) window.

Is there a way to fix this? Please help.

Thanks
