I am on Firefox 152.0 (64-bit).

When I view a pdf in Firefox it looks centered like a normal page.

When I send it to print from there, it left justify the pages. I have tried changing the Scale, Margins. The paper size is Letter 8.5" x 11". I have 2 different Canon printers (laserjet and inkjet) and no difference.

If I download it and open it with Microsoft Edge and send it to print, it prints centered like a normal page.

I have tried to search articles on this topic. They were all very old. Some says to make changes in about:config in the address line. I tried a couple. Yet no difference.

Hope you can help.

When starting firefox I had 5 windows open. After a MAC notebook restart, I tried to open firefox and then the five pages showed to disapear when I clicked on one - nothing can be seen. On the firefox icon I cannot do anything other than look at "About firefox" to learn that it is up to date. I have no idea what to do to get it started again ... thank you so much for any guidance here

When opening a new page in Firefox I am shown a few widgets.

It shows the time of sports events and different timezones. But it shows this in a non-local time format - the 12 hour format (so it says 06:00 PM instead of 18:00).

In about:config I found a setting called "browser.newtabpage.activity-stream.widgets.clocks.hourFormat" but what are the acceptable formats to use here? It's not a boolean value, and by default nothing is there. I tried writing 24, HH:mm, and some other things, but didn't notice a difference.

I want to use the VPN, but when I sign in, and click the "VPN" button on the top right of my screen, it just takes forever to load. I don't think it ever loads. Then when I reset, it just says the same thing :Try Firefox's built in VPN.

Firefox just updated to 152 this evening on my Windows 11 Pro system. It seems slow compared to prior versions. Also , every time you log out , it crashes and activates crashreporter which files the report. Any clues? Nothing changed on the system except for Firefox.

Hello,

I had seen this topic : https://support.mozilla.org/en-US/questions/1489702, i'am using a GPO to deploy an Lockself (password manager) extension on Firefox 152 on all computers in my company. I wanted to pin to navbar just this extension, because users will ask at first time where is it. I have changed the JSON to pin to navbar :

{

 "{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,
   "default_area": navbar
 }

}

But when i reload the GPO on a test machine this GPO isn't applied.

So it seems the bug isn't solved ?

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.

Tabs will crash over and over again. I can barely look at any given page for longer than a minute or two. What happened?? Firefox was never like this before. It just crashed in the middle of me typing this LMAO. Using Brave in the meantime. This is ridiculous.

Hello -

I cannot correct misspelled words when using Proton Mail. It has worked in the past, until recently. Perhaps the latest Mozzilla update? In the body of my email Proton email shows the words which are misspelled but I cannot right click to correct the spelling. Proton never seemed to support the "subject" field typos but did support spelling correction in the body of the email. The spelling correction works properly in Google docs.

Spelling correction is turn on in Firefox settings.

- Firefox 151.0.3 (aarch64)

- iOS Tahoe 26.2

Since the update to Firefox a few days ago, I am no longer able to view PDFs in the browser. They still open, but they show up as blank pages. Is there a way to fix this or to revert back to the previous version of FF?

Thanks.

After reinstalling my computer system, I logged into my Firefox account again, but the data synchronization failed. All my previous data is gone, including bookmarks, passwords, and widgets. What happened? I can't find them in the mobile app either.

In this version of Firefox 152 for windows I'm currently unable to remove search related to google, ebay, perplexity and bing.

Please return possibility to remove those completely!

I don't want my browser to have anything to do with those listed above. I have had it removed in previous versions. Why did you add it to browser again?! Why don't you allow to remove it anymore?!

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.

As title says, on my main profile, i dont see any option to use the new tab widgets function. If i make a new profile, it is there on default.

How to add it on my main profile?
