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 have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

Recently, whenever i have to quit firefox, my tabs have all disappeared upon opening. I have tried all the suggestions in the Mozilla help and nothing seems to work. This used to happen from time to time which was frustrating but now it happens every time I need to quit firefox. "Recently closed tabs" and "recently closed windows" are greyed out when I try to use that. and there is nothing in "restore previous history". Thank you for your help.

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

Hi -- I'm getting quite a few page crashes that seem mostly tied to YouTube, although not exclusively. I only recently swapped over to Firefox from Chrome because I was having similar crashing issues with that browser as well. This is after a fresh install of Windows 11 Pro and a number of different benchmark tests (no known issues with CPU, GPU, or RAM).

Since there are so many reports that all seem different, could someone help troubleshoot? I really can't tell if it's a browser problem, maybe something with my MOBO or PSU or other hardware.

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.

Reader view doesn't work on many Lifehacker pages/articles. Can something be done to make it work on those pages? Here's an example:

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

There have been several links or Youtube movies that come back saying that my browser doesn't support that page.

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.

whenever I do a Firefox update, there sometimes is a new extension included that I personally feel no use or need for..most of the time I can disable them w/programs like Ccleaner (see image), but some are persistent, and return the next time I open Firefox. Firefox always consumed a significant portion of my 8gigs of RAM, and my latest update to 144.02, it is approaching 15%. Any way I can stop this short of reverting back to previous version?

The tab group suggestion feature is unavailable for me, even though I am on Firefox 145.0 (64-Bit on Windows 11 Pro 25H2). I tried using guides like [one from mozilla] https://www.askvg.com/enable-or-disable-new-ai-powered-smart-tab-groups-in-firefox/ this external about:config editing guide.

The latter does changes to the about:config. A screenshot of my settings, my config, and my Add-ons is attached.

I do not know what is wrong.

During the last desktop update I lost all of my bookmarks. I’ve tried to sync between my iPhone and desktop but when I finally got paired nothing happened with the sync from my phone to desktop

So I'm just idly doing cleanup / maintenance work on my saved passwords and have encountered the most ridiculous error message:

• Vulnerable Password
• Learn more\
• This password has been used on another account that was likely in a data breach. Reusing credentials puts all your accounts at risk. Change this password.

Except I know the password is unique.

I have a strict username / password usage where every site gets a unique password, period.

Someone broke something in when it calls ABC = DEF

26200.6899 - Windows 11 pro OS version 144.0.2 (64-bit) - Firefox version

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

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 really do like the new vertical tabs and I have them set to be just icons until you hover the mouse over them and then they fly out and I can read the names of the tabs. My problem is that when I switch a tab or do anything that makes the tabs expand to see their full names if I take the cursor off they fly back in but if I put the cursor on any area of how far the tabs came out to in the next few seconds they come out again even though I haven't put my cursor over the tab icon. This is really annoying for forums and really for general browsing as if I switch to a tab and want to interact with anything where the tabs came out to I have to wait like 5-10 seconds before I can click anything on that part of the page or else the tabs come flying out again. Is there any way to make it so the second my cursor isn't over the tab fly out that they will go back to the compact mode and won't come back out unless I hover over the tab icon again to alleviate this problem? I find I will often switch to a tab and then move my cursor off to the page and the names collapse so there are only icons left but I try to interact with something on the left side of the page and the tabs fly out way before my cursor goes near the tab icon and I have to take my cursor to the right then try going back to interact with that element and most of the time I have to go back and forth a few times before the tabs stop flying out so I can interact with that portion of the left side of the web page. I really like the vertical tabs but I want to be able to edit the time it takes for them to not fly back out if your cursor goes to where they had flown out to immediately, so zero seconds, instead of the 3-10 seconds or whatever it is set at by default.

Thanks!
