Firefox Community Forum

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

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.

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.

After a few minutes of usage, firefox keeps freezing and crashing. Very frustrating. Seems to have started happening after recent OS upgrade.

On windows 10, I had my history setup perfectly. I had it where it saved all of my stuff all the time and I could go back and check anything on any day. Then I changed to windows 11 and now my history is a mess and I can't figuar out how to fix the problem. I am not good with computer, so make your answer SIMPLE AS POSSIABLE, please!!! Thank you.

Hello!

I am getting consistent issues with Firefox where the tabs seemingly just crash with no rhyme or reason to them. Could be within a few seconds, could be after a few minutes. Doesn't seem to be one website causing it either as I was worried it was Twitch but I get issues browsing other places too. Any help would be appreciated!

Here are the last 5 crash reports:

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

Hi! So I just installed firefox and I got onto annoying issue. I like using shortcuts on my homepage, but I started to get some shortcuts added automatically and they bother me a lot. I tried removing them or deleting from history, but as soon as I click the button, one shortcuts gets removed and immediately gets swityched with another one automatically. So I'm stuck in the infinite loop of removing shortcuts and my manually added ones just get lost in all this mess.

Tonight I received a notice that a new version of Firefox was available and asking if I wanted to download it. It showed me the new Kit mascot so I decided to let it install. It seemed to install normally but when it tried to open what I guess is a welcome/new features page, it crashes, and just showed a prompt to try again. This continued in an endless loop and I had to shut it down. Unfortunately I no longer had a functioning version available that I could find so I downoaded the ESR version to be safe (ver 140.5.0esr) which I am now using. Somehow I was able to recover bookmarks and hopefully other saved info. Can anyone advise what has happened? I have used Firefox for many years and never had this sort of problem before. Running Windows 11 on a new Dell i7 PC.

Hi there! I find the new sidebar (on the left for me) a great addition but is there a way to reverse the "top to bottom" tabs displaying order?

Not a way to move tabs, but a setting allowing, when opening a new tab (Ctrl+t), to place (and display) the icon on top of the tabs icons pile, not at the bottom.

I get that it's the opposite of the normal reading direction, but it's rather unnatural to go looking at the bottom of the screen for recently opened tabs, IMHO.

Thanks in advance if you can address this, or show me where I can find such setting.

Best regards from France, Jc

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.

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!

Unlike before, many sites that I visit regularly, I am now having to log in every time I visit, including support.mozilla.org.

Did I unknowingly change something, some setting? or perhaps it's due to an addon?

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
