Diễn đàn hỗ trợ Firefox

Firefox is updating 2-4 x/month while in use and has to be restarted. But my setting is on "Check for updates, but choose when to install". The last update recorded is listed as February 2026. So what gives? Thanks

Firefox has just updated on my Windows 11 PC at around 1100 17/06/2026 and now I cannot access my Spanish banking online with Banco Sabadell.

When I try to log in I get a message saying 'the process cannot proceed because of security issues.'

I could log in prior to the update and I can still log in using Brave.

By process of elimination I deduced that it must be something to do with the update.

I tried to sync my desktop and mobile today. Nothing loaded to my mobile a fact I am now gratefull for because my desktop did sync with the cloud ERASING an entire year of deleating broken bookmarks. What I want to know is how to deleate the cloud so this never happens again!

I am finding more and more that i have to go to Chrome to fill out forms. When there are check boxes on a website like the League of Women Voters to renew membership i find i can not click the box when using firefox. has something changed across the web or is there a privacy setting i can disable temporarily or ... something else? i really try to avoid Chrome but it seems that is the one browser that works consistently. And now i try to click the box at the bottom of this page to get email answers and it doesn't work. wow.,

I'm using 2019 MacBook Pro 16" with OS Tahoe 26.5.1. When I click on "Print using system dialogue box" it takes me to the Mac print dialogue box as expected. When I select the option to open the page as a PDF in the Preview app, it sends it to my default printer to print instead. Very strange behavior. It only started doing this in the past week after installing the latest Firefox update (152.0 (64-bit)). I haven't downloaded any new programs and it happened well after the last OS update. I've reset my printer settings in Firefox, I've tried repeating it in "Troubleshoot Mode." No luck. The error doesn't happen in other applications like Mail App or Safari. Thank you for any insight or fix you can think of.

i had two different firefox browsers yesterday. I deleted one but all my passwords are gone from the other browser. When the firefox browser got uninstalled it created a backup on my desktop called bookmarksback up. how can i move that file into this new firefox and how can I retrieve those passwords?

I am no longer able to open in Mac Preview or save when hitting Command + P, then 'print using system dialog'. It will only print instead. For instance, I save certain web pages as PDFs using the print dialog and now it will only print when trying to use either the save or preview options. Command + P, print using system dialog, then I choose either save as PDF or open in Mac Preview, but as soon as I do one of these it will only print. I am able to use save in the drop-down list of printers, but I need to be able to open in Mac Preview.

Hello,

I'am testing a GPO to deploy the Lockself extension on windows 11 for Firefox 152, the JSON used in the GPO setting is the following :

{"{ca613ee6-4211-4ae2-aa3c-d29608461d11}":{"installation_mode":"force_installed","install_url":"https://addons.mozilla.org/firefox/downloads/latest/lockself-password-manager/latest.xpi","updates_disabled":false}}

And i have enabled an another setting to prevent the extension to be disabled or uninstalled by specifing the ID of the extension : ca613ee6-4211-4ae2-aa3c-d29608461d11

The policies are visibles under about:policies and they don't show any error.

The issue is that i'am still able to disable Lockself but going in Firefox parameters then under password and autofill. On the image attached, the button "Desactivate the extension" is here and you can use it, it disable the extension.

Regards

Hello,

I have a few problems at my house and am trying to send photos of my garden gate which is not working. I cannot upload these photos as I get a message "Vous n’avez pas les droits nécessaires pour téléverser ce type de fichier" which I've translated to "You do not have the necessary permissions to upload this type of file.

I am using Windows 11 (this is nothing to do with Onedrive as far as I am aware).

This is a recent problem. How can I sort it please? The photos are on my Desktop as they are easier to find here.

Hi, I'm using Firefox on Desktop and Mobile. For last couple of months, I've been experiencing a problem of Shopify stores loading. When we open any Shopity website (stores specifically), it never loads. Sometimes it shows blank page and sometimes nothing.

At the same time, those sites are working fine in other browsers e.g. Chrome, Safari.

However, when I switch to other wifi network (jazz.com.pk), then it works on Firefox too. I tried different methods to fix it, but no success. Before the websites were sometime opening, but for lost few days, 0 response.

Not sure, where is this issue, I contacted my network support (nayatel.com), they also unable to figure it out.

I tried everything on my end, but no success. Need your help.

I may have a problem with the new Firefox version 152: from my online application, I send a command string to a local printer reachable at https://192.168.1.xxx. It often succeeds, but sometimes it gets blocked. I don't understand what the problem might be because I don't get any error messages. The only thing I see that's different from the usual is this:

Local network access detected: main site "https://www1.storesales.it/alpha/RTL/veve.php", initiator "https://www1.storesales.it/alpha/RTL/veve_chiudi.php", accessing destination "https://192.168.1.xxx/cgi-bin/fpmate.cgi" (192.168.1.xxx:yyy) via xhr. Safe context: True, action prompt: (null)

However, it looks like an informational message saying everything is OK.

It seems that Firefox sometimes waits before sending the XHR call, which causes the call to time out. I have no evidence to confirm this. I don't know where to look for evidence. What can I do?

Hello, for some time now I've been experiencing a number of problems with the latest Firefox updates.

Today I have version 152.0 (64-bit), which was updated again this morning. I restarted my mid-2015 MacBook Pro Retina. I have fiber optic internet, which is very high speed.

I've been using Firefox for over two years.

1) For the past eight days, I've been experiencing many problems with Google Meet; I get freezes, audio and video dropouts...

2) For the past three days, I haven't been able to log in to this website: https://creators.spotify.com/pod/login

3) For about ten days, I've been having trouble logging into my Stripe dashboard, with significant slowness and/or crashes.

4) In Notion, I'm also experiencing significant slowness, with pages taking a long time to load.

In short, several problems that I didn't have at all a month ago or before.

But now it's a nightmare.

I don't have any of these problems in Safari or Google Chrome.

So what's going on in Firefox?

Why is it such a hassle?

Thanks for your feedback.

Today, after the last update of the software, I lost ALL my tabs (2 years of materials) and there was no way to recover them. Furthermore, I had to spend hours to retrieve at least the most important tabs I use for work.

This is not acceptable, please fix this issue and make the recovery of tabs possible and easy.
