I was assured transition to Firefox was seamless, but everything about it so far has been anything but.!The final straw was 3 step process to sign in to BMO online (just password w/chrome) Here its get verification code or go to extensions, ad blocker off, sign in to BMO, sign out, back to extensions , turn on ad blocker, carry on. Really? Settings suggestions seemed a bit like trial and error, and more time essentially wasted, as I now have a few hours invested trying to make this work for me. I am, admittedly no tech wizard, but neither an I stupid. I am minutes away from reversing the whole process and, much as I hate to, going back to the over-reaching arms of chrome/google. As I am not really expecting a response here, I realize this will just boil down to venting. There is much to Firefox that I liked, but the transitional road-blocks are exhausting . I will say it felt great to finally take that step, however temporary it was.

Hi,

I added some annotations to a PDF using Okular on CachyOS. When I open the PDF in Chromium’s built-in PDF viewer, the annotations appear in the correct positions, just as they do in Okular. I also checked using a few online PDF viewers, and the annotations display correctly there too.

However, when I open the PDF in Firefox, all the annotations appear in different positions than they do in Okular.

Desktop version update to 157.0.1 acted like a fresh install. Prompted me to import from previous browser. Firefox was my previous browser. I have my bookmarks backed up, but lost all my tab groups, which is a huge problem to try and recreate. Lost downloaded themes. Lost downloaded extensions. Why did this happen? I can't imagine it was by design.

I've been getting access denied from more and more websites. I messaged a manager from the website shown below, who said my browser was not up to date. I update my Firefox browser when it asks. I did it yesterday, but still got this message today. I haven't updated my macOS because I have been keeping some old software alive. That is no longer necessary. I am now running macOS Mojave version 10.14.6. I can upgrade to macOS Monterey version 12. Is it worth making this update? Will this solve my access denied issue from certain websites? Is there another way to fix this problem?"

Hello, I’ve run into a problem: after installing update 156.01, whenever I go to a link to join a Google Meet conference, the page starts reloading endlessly (including when I click the "Join" button). I’ve already tried disabling protection and hardware acceleration, clearing the cache and cookies, and even accessing it in Safe Mode, but the situation hasn't changed

I am trying to login to one of my online banking websites and I am getting this message "Firefox prevented this page from automatically reloading" and when I hit the ALLOW button, nothing happens. I don't know if this related to the latest Firefox update ... but it's a real problem for me. I have to keep switching over to Chrome to login in. Please advise what I need to do?

it is obvious your system has changed: I have windows 11....the help I see is for windows 10

where are the current updates?

Sometime in the last week or two, every page starts with a banner that says "you must sign in to the internet to continue". I'm already/always signed in. On those few occasions when I click on the network login link (rather than clicking X to dismiss this dangerous and wrong banner), it shows a very dangerous site and says that site is prohibited. (As it should be.) So why is the banner demanding that I log in (forcing me to click X to dismiss it)? This feels like your site has been compromised, that some malicious actor is forcing this prompt on every page. (And even after I click X to dismiss it, it reappears 10-15 minutes later.

I am having an unusual problem with my main Firefox profile on Windows 10. The affected profile is:

C:\Users\Adam\AppData\Roaming\Mozilla\Firefox\Profiles\2giwv8i8.default-release-1746901618396

Firefox reports that this profile contains a user.js file. I cannot read, rename, move, modify or delete this user.js, even from an elevated Administrator CMD or PowerShell session. Attempts return “Access is denied.”

The unusual part is that Windows permissions appear correct. icacls shows my user account, SYSTEM and Administrators all have Full Control. The file is not encrypted, is not read-only, is not a reparse point, and Firefox is completely closed when I test it.

I also tested writing a new file directly into this Firefox profile directory and receive Access Denied. Other older Firefox profile directories on the same NTFS drive are writable, so the behaviour appears specific to certain Firefox profiles.

I have already performed a Firefox Refresh/reset, but the problem remains and user.js is still present.

I am investigating this because I am also experiencing unusual behaviour specifically with this main Firefox profile when using YouTube. Other Firefox profiles do not reproduce the same behaviour. I therefore want to completely eliminate any persistent profile configuration as a cause.

Can someone explain:

What could prevent access to an entire Firefox profile despite NTFS ACLs showing Full Control? Can Firefox, Firefox Sync, Enterprise Policies, an extension, or another Firefox mechanism protect or recreate user.js? Why would Firefox Refresh leave or recreate user.js? Is there an official/safe way to identify which preferences are being loaded from user.js when Windows itself refuses access to the file? Is there a way to reset all non-default preferences in this profile without losing bookmarks and saved passwords?

I can provide about:support, about:config, profiles.ini, ACL output and other diagnostics if required.

I would particularly appreciate advice on diagnosing why the profile directory itself returns Access Denied despite Full Control, rather than simply creating another profile, because I would like to identify the underlying cause.

I switched to Firefox from Chrome as my computer is too old (OS-High Sierra) and wouldn't support Chrome any more I've had to restart several times and each time I reopen Firefox, all my tabs are deleted. How can I prevent this and/or restore my tabs?
