Firefox Community Forum

Hi everyone, I’m managing an online bill information website, and some users reported an issue when they try to download or print a PDF bill using Firefox. Sometimes the print preview doesn’t load, or the layout breaks, while it works normally on other browsers.

Is there any recommended Firefox setting, extension, or workaround to prevent this issue? Also, is there a specific print CSS or PDF format Firefox prefers to handle better?

If testing is required, this is an example page where users reported the problem: https://fescoebillcheck.pk/

Thanks in advance for any guidance.

google is saying cookies are disabled when using FF to login. This was working Privacy is set to STANDARD and I went into settings and removed google.com as well to no avail.

How do I fix this?

Thanks leon

Hello I am having major problems with Firefox at the moment and have done for a while. I curently have four pages open but as you can see from the attached screen shot of my Task Manager, there are 14 Firefox processes. The usage is OTT on memory and everything else. Could you tell me why this is happening? Currently it is running in Troubleshooting mode but that is not doing anything to improve the problem. It has been known to shut my computer down, as it gets too hot. I run on Windows 10 and Bitdefender is my security. All help is gratefully received. Thanks Lisa

I generally always use Firefox on my PC for everything.

I also often chat with Amazon as they are never short when it comes to fucking my orders

I have not used Amazon for the past 2-3 months and when I finally placed a new order 3 days ago, to resolve the usual non delivery issue, I contacted them via Live Chat, however instead of seeing Chat window pop open as usual, all I got was ABOUT:BLANK in new tab, hmmm...

So far to fix this or at least ascertain cause:

- I contacted Amazon.fr (where I live) and guy at digital services said, "nah, no flies on us, it's Mozilla's fault" - Edge, on same PC (windows 10), works OK for chat - Launching in safe mode changes nothing - Nor does disabling NordVPN - I also added Amazon.fr as "exception" in pop-ups, to no avail - and when I unchecked block box to enable all pop-ups, no better luck - lastly, on my iphone via Safari, all is good, assuming one enjoys typing with 1-2 fingers

my version of Firefox is up to date: 144.0.2

voilà

suggestions?

thanks

After most recent update all my bookmarks and passwords disappeared and I cannot seem to recover them. This is extremely frustrating. Has anyone else had this happen? I tried using the recovery process but it did not work.

On Windows 10 with 64-bit Firefox, after updating from version 144 to 145, some local HTTP-only servers stopped working and became inaccessible. When I enter http://<local server name>, after a few seconds it automatically changes to https://<local server name>, and since no HTTPS service is running, it ends with a “Server not found” page. It seems to be related to DNS — accessing http://<IP address> works fine.

I tried a clean installation with a new user profile, but it didn’t help. Downgrading to version 144 fixes the problem, but at the cost of losing the user profile (which is a disaster). I also tried to check the HTTP-only settings (which I’ve never modified), but that didn’t help either.

Is anyone else experiencing the same issue?

Heya,

I am the maintainer of the British Dictionary.

For one year that I have been working in the "shadows" on my version of US+Canada+Australian, to be released on 1-JAN-2026.

Can I add your list of proper names (~5000 words) to my dictionaries and release the dictionaries as LGPL?

Thank you!

So this morning I sat down at my computer which was already on and working fine yesterday. Today my bookmarks had disappeared. I rebooted several times, closed and reopened firefox several times and I don't remember what else I clicked on but my bookmarks had reappeared. I sat down at the computer a while ago and opened firefox and my bookmarks seemed to have disappeared again. Before when I clicked on bookmarks up on the toolbar my bookmarks would appear. Now I have to click on bookmarks then bookmarks toolbar to see them and now all of my logins are gone. Should I just ditch this browser and use chrome or is there some simple fix? I never have had as many problems with a browser as I've had with firefox and I no longer see an advantage in using it.

I believe I had all this synced in Firefox Settings before I made the upgrade. Like all you fellow former users of Windows 10, I had to upgrade to Windows 11; and did so two days ago. Now, I found that I do not have under History any of the former sites I not only visited but also had tabs open. What can I do, if anything, to recover them? Under the Add-ons Manager, if this helps, I already had the app Tab Session Manager, but don't know how to use it. Thanks to all in advance who may have made this same upgrade. Many out there are still on Windows 10.

Hi everyone, I manage https://myphoneoffers.com, a website that lists mobile phone prices and SIM packages in Bangladesh. I’ve noticed that a few JavaScript-based components (such as floating offer banners and comparison tables) don’t always load properly in Firefox. In some cases, it looks like ad-blocking or strict tracking protection might be preventing the scripts from running. I’m using lightweight JavaScript with no third-party ads — just local scripts and analytics. Could anyone explain how Firefox’s Enhanced Tracking Protection or JavaScript settings might affect embedded scripts? And what’s the best practice to make sure essential scripts still load while maintaining user privacy? Any insights from web developers familiar with Firefox’s JS behavior would be really helpful. Thanks!

2 days ago you tube is suddenly blocked. 11/6/2025 i would click a video, it would "blink" at me and do nothing. i updated firefox, ublock was updated about a month ago and now i can't even get a home page to load. i have refreshed and restarted

Hello Mozilla Support Team, I manage the official website of ITTP, which provides information about our JBT from Haryana JBT from Haryana course. Recently, I noticed that the website isn’t working properly on the Mozilla Firefox browser. Some pages load slowly, and certain design elements like buttons and banners are not displaying correctly, even though the site works fine on Chrome and Edge.

I’ve already cleared cache, checked extensions, and verified that our SSL and JavaScript files are properly configured. Still, the issue continues on Firefox across multiple devices.

Could this be related to compatibility settings, outdated scripts, or browser-specific rendering issues? I’d really appreciate any guidance or troubleshooting steps to ensure the ITTP site runs smoothly for users searching for JBT from Haryana information.

Thank you for your help!

Launched this morning and the interface is totally different. That's not the problem All my bookmarks are gone and I'm unable to restore them

Can I move back to the previous version of FF?
