How can this be allowed to happen? This goes against everything private browsing is supposed to be.

I open a private window' log in to gmail, reddit, amazon, any site, etc; i close private browsing window entirely - removed from taskbar; i reopen private browsing and all my sessions are still signed in.

The fact that this is happening is negligent to the point of criminality. WHAT is the solution and why is this being allowed to occur?

For the past two months, I've been trying to sync Firefox (114.1.1) on my Samsung Galaxy phone (SM-N950U) with Firefox browser (114.0.1) on my Windows 11 Home laptop. On the phone, it works fine. On the browser, when I go to firefox.com/pair ... I get to the screen with the bar code, when I scan that bar code on my phone, the windows Firefox browser gives me an Error 500 (see attached.) Your help is appreciated!

I have tried updating Firefox a number of times to 115.0.3 and each time I have had to roll my PC back to a pre-update state because I get a warning from MS Defender that I have a Trojan. What do I do in order to update the program without this very disconcerting warning?

Thanks in advance.

Firefox 114 introduced hidden support for nvidia video super resolution. In about:config you can enable preference gfx.webrender.super-resolution.nvidia to make it work. However I see 0 difference on all videos on all pages. I have everything in nvidia control panel set correctly (VSR enabled and set to 4/4 quality).

Tried to find more info online and someone on reddit complained that it worked before but it stopped working with latest firefox beta (probably before final 114 release): https://www.reddit.com/r/firefox/comments/13duluz/nvidia_video_super_resolution_comes_to_firefox/

I tried using logic too - if this pref is related to webrenderer in its name maybe it is not working because I am not using webrenderer? However I checked about:support and in section graphics->composition I have "webrenderer" so it seems I am using it, but its VSR feature is not working at all.

What is the code to remove that new menu Search Bookmarks in new firefox 114?

I already remove all the previous "bookmark all kind of type menu" in userchrome.css

DIRECTLY after 114.0.1 update, I get a CONSTANT UNENDING PROMPT telling me all about firefox , ON EACH AND EVERY SEARCH, I am here to find out how to remove this intentionally annoying, "thing" from MY PC(of course Mozilla couldn't be bothered to tell us they were installing a continuous advertisement for google, and FORCE installing it as search engine). I want this endless advertisement removed, post haste.

I created an account today and let Firefox generate a password, clicked save and everything seemed normal. but when i went to login on another devise and pulled up the password i find is my SSN.

I am baffled how this happened. Why is it not designed it automatically save the created password when creating the password? Why and How did it find and save my SSN? I don't understand how the computer messed that up, I created and saved the password then I gave my information including my SSN to finish creating my account. Then the last step to create the account was to download the app and login on my phone. So I go to my Logins and passwords and find the password it saved was my SSN not the random password it created the account with.

I don't know what to do, probably have to start over if it cannot be recovered. But I want to complain about about Firefox picking out my SSN. Failing to save the password is one thing, But replacing it with my SSN is wrong. And i do not think I made a mistake here when all I did was click two buttons, create password and save password. they popped up one after the other I clicked them both in seconds from one another. My SSN was not on the page at the time, I created and saved the password and gave my SSN in different steps one before the other. I cannot rationalize how this happened.

I have lots of bookmarks, which I organise into folders and subfolders. In the last month or so, Firefox will no longer save them to the folder I specify from the pull-down menu when saving but just adds them to the general bookmarks menu. To sort my bookmarks, I have to go into Manage Bookmarks and move them manually. What's happened?

Within the last hour or so, I needed to close Firefox while installing an app (the setup was recommending to close all Windows programs).

Had 8 windows open.

Right-clicked on the Taskbar Firefox icon, then selected the option "close all windows" - it proceeds to close each window consecutively, asking me each time for manual confirmation whether to close this window with x tabs in it - and I just confirm each time.

So then after that setup is completed, I open Firefox again - the last closed window is restored (as per the settings);

then I click on History, "recently closed windows", and.... there's only 2 windows on that list. I restore those 2, and then the list is empty - nothing more to restore.

So if I had restarted the PC, it would've just restored the 8 windows upon reopening Firefox, as usual - but since I opted to just close Firefox like this, "close all windows", I just lost 5 windows.

So could anything be done here?

Something in the files? Maybe the C:\Users[user]\AppData\Roaming\Mozilla\Firefox\Profiles\4qu1kfr9.default-release\sessionstore-backups path? There's a file called "previous.jsonlz4" in there, something I could do with that one?

Or something else?

Any help would be appreciated!

Hello all! Thank you for reading this. I will attempt to be concise. All download attempts from firefox fail regardless of file type. I have done all of theses; https://www.guidingtech.com/fix-mozilla-firefox-downloads-failing-on-windows/ and I have done all of these; https://support.mozilla.org/en-US/kb/cant-download-or-save-files

The facts Dell 7490 Laptop. Windows 10 Pro 64 bit, version 22H2, OS build 19045.3086, Windows Feature Experience Pack 1000.19041.1000.0

Firefox version 114.0.2 64bit

Possible relevant information. I also encounter an error when starting Firefox that I cannot resolve. XUL Runtime error. I have attempted all the fixes here; https://support.mozilla.org/en-US/questions/1398228

Any help would be greatly appreciated. I love supporting Firefox but I"m not sure how much longer I can use it with this problem.

Thank you, Everyone!

I tried to log in to a website that requires access to my location. I'm using Firefox 114.02 on an iMac running Monterey 12.6.7. I was able to get in to Firefox's Location settings and now have the website listed with "Allow" noted. This was not enough, and for some time I didn't understand why. Then I discovered the Mac's System Preferences' Security and Privacy section, where Location Services are one category under Privacy. Selecting Location Services brings up a list of apps that are allowed to provide location information. For some reason, other browsers are on the list and can be turned on or off, but Firefox is not on the list of apps that can be selected as permitted. Am I missing something here? I can't find any way to add apps to the list so that they can actually be selected. Any advice?

Yahoo websites blocked from within the US. I get the following message: "When trying to access my yahoo mail account from within the US I get the following message: Yahoo’s suite of services will no longer be accessible from mainland China." Any thoughts on what is happening and how to correct it? I'm in the US using the Mozilla VPN with a US server location

I get this error when trying to access my email using FireFox. Lately this (or a similar) error happens weekly if not every couple of days. Always first thing in the morning, too.

my email works just fine using Safari so I am at a loss.

I have tried running FF (Firefox) in safe mode, ensuring outlook.live.com is an exception to the pop up window blocker, changed default protections on outlook dot com to none from standard.... Turned off ABP, clearing cache and cookies from within FF.

it may be worth mentioning that I can still browse/access other websites while outlook produces this error, and my network settings within FF are set to use default system settings (no proxy).

Hello Firefox,

When loading a page I work on, I sometimes see something like this:

14:54:44.103 Error in parsing value for ‘margin’. Declaration dropped. instantiate_obj.php (With a yellow-ish triangle with an exclamationmark in front of it)

The warning is clear: somewhere in the html/css a faulty margin-value is used.

But how to find out where, or what causes it?

Is it something inline, an external CSS, something dynamically added by javascript?

What I tried:

1)  Clicking on the link on "instantiate_obj.php" just opens a tab in "view-source:" mode.

Not very useful. I don't see any problems on quick inspection, but the page is pretty big. I want something easier than checking everything in the source and the linked CSS.

2) Looking at the timestamp (14:54:44.103) I see it ends in 103. Maybe a linenumber?

Nope, that particular line contains only
.

3) Searching https://developer.mozilla.org didn't shed any light on how to approach this problem.

I can only find out references on how to do it when you see the yellow-ish triangle in inspector, in the second pane (css with that 'filter styles' on top) I already checked my external stylesheet and it came out fine.

Does anybody know how to find out what caused the warning?

I asked also on stackoverflow but didn't get a response, so for reference:

I've been having a weird issue with my text glitching only in my Firefox browser. Initially I thought it might be my monitor but then I realized the issue only presents itself in my Firefox browser. Literally no other program is affected.

I've done a reset, I've uninstalled and done a clean install, I've deleted all Firefox files and re-downloaded the browser. The issue immediately pops up again.

It seems Firefox is getting worse and worse. I am now back to pages loading very slowly. My IT guys say firefox is [redacted] and go to chrome or something else but i hate transferring bookmarks. WHY can't you stabilize your [redacted] browser. Yours is the only browser my PC runs into trouble with. Makes me [redacted] furious.
