I'm a gamer and alt+tab considerably often. Most of the time I end up on FireFox because I need to look at a map or browse reddit while I'm in queue. However, whenever I alt+tab frequently a bookmark will get selected as if I am clicking and dragging. The bookmarks on the bookmark tool bar always end up in different places. Is there a way to lock these links in place so I can't move them or do I have to resign myself to fixing it every day?

www.google.com. PR_END_OF_FILE_ERROR www.facebook.com. PR_END_OF_FILE_ERROR Hi, This occurred after a moment of power loss during a thunderstorm on my Lenovo desktop. All my other sites as far as i can tell are ok. I used Edge and was able to access FB and Google on Desktop] i checked and the current version of firefox is installed on desktop

even weirder, i can access both google and FB on my laptop with firefox. I've tried syncing the two with having bookmarks etc. i can sync from laptop to desktop but not vise versa.

i thought I'd uninstall and reinstall firefox but i don't want to lose any info esp my Bookmarks on the Desktop hence why i was trying to sync the two.

My desktop is older, maybe 5-6 years, my laptop is 1 year old. Dunno if this matters. thanks, Jan

Hi all,

Recently, my win 10 crashed and although I managed to recover some operative, I found to my horror that the desktop screen text size and contrast cannot be changed now. The current default setup is a real eye sorer, so I opened personalization settings but there is nothing on how to change this very theme, other than other posts suggesting entering the regedit system files. I am very reluctant to tinker with this given the Win10 application crashes. Running maintenance doesn´t do much. I notice that Firefox also has access to this very text size and font theme for web domains, but I am very wary again of tinkering an unknown. What the heck can one do, confidently without the system resetting itself? One thing is for sure, it seems Win10 home edition update 21H1/2 versions is basically treating users very badly, as if MS wants to ignore them. Bless us all when the embedded caption suggests "ready to update to Win11". I´m highly inclined to bin it.

FireFox keeps putting a .jpg at the end of any file I try to download with .exe as its extension and adds a .jpg, example, when I download QU210InstallFiles.exe it changes it to QU210InstallFiles.exe.jpg and I cannot there for install the program because it has the .jpg added to it and it wants to open in windows media viewer instead. It never use to do this, what have you guys done....uuhhhh, any help would be nice and I thank you. Daniel Goggia

My System Mechanic malware search system has quarantined a virus located in two Firefox locations: Virus is W32/Trojan.YZST-9002 LOCATE IN: C:/PROGRAM FILES/MOZILLA FIREFOX/UNINSTALL/HELPER.EXE C:/PROGRAMFILES/MOZILLA FIREFOX/MAINTENANCE SERVICES_UNINSTALL... I will use the delete process and remove them and watch for future loads.

Hi Mozilla community,

The Developer Tools -> Storage -> Cookies pane shows cookies currently being stored by Firefox.

If I close my browser, these cookies are automatically deleted. However, if I follow the steps on [1], the cookies are still there, and don't get deleted. *Why?*

Thanks in advance!

Steps to reproduce:

- Start a new Firefox session
- Open Developer Tools -> Storage -> Cookies and see that the list is empty
- Go to youtube.com and click Accept All on the cookies popup
- Developer Tools -> Storage -> Cookies now shows a cookie from YouTube, as per the attached screenshot
- Go to Settings->Privacy & Security->Cookies and Site Data -> Clear Data -> Clear
- Go back to Developer Tools -> Storage -> Cookies and click on the refresh icon
- The YouTube cookie is still there
- However either of the following actions will correctly delete this cookie:

1) closing firefox (with Always Use Private Browsing Mode enabled) 2) manually deleting the cookie from the list in Developer Tools -> Storage -> Cookies

Hi support team,

Yesterday, I suddenly removed all logins and somehow my profile was synced to the cloud.

Fortunately, I still keep all login files (json and key db files), I tried to recovery all my logins, it was successfully.

But, right after that my profile was synced from the cloud to my machine then whole logins were clear.

So how can I overwrite my profile in the cloud so I can totally recovery my old logins?

Kindly help to give my some advice.

Thanks!

This computer is about to crash so I have a laptop backup. I have copied my Firefox profile before from my last computer to this one that is crashing without issues at all. It copied all of my bookmark data, settings, logins, themes, add-ons, etc last time. This time it refuses to read any of the files copied. No add-ons, no bookmarks no nothing. I need this taken care of ASAP as this comptuer is on it's way down and the monitor likely only has days left the way it's running. Why does copying profiles no longer work? I know how to do it and I did the exactly the same as I did before. It's been an hour fighting with it and nothing is working. I need this done ASAP.

On some websites (namely, twitter), middle clicking a post opens it in a new tab. However, whenever this happens, the new tab is always focused, is there a way to prevent this from happening?

This does not occur on websites such as Youtube.com, where middle clicking a video opens it in a new tab, but does not focus it. This is the preferred result.

Likewise, when middle clicking a bookmark, the newly created tab is also immediately focused. Is this preventable aswell?

Thank you for your time.

READER VIEW icon is missing from the toolbar, and ENTER READER MODE is missing from the VIEW menu, even on sites/pages where it is enabled on my other computer. Firefox version 104.02

Hi everyone,

lately I started experiencing a font-family-related issue. On certain websites the font-families/styles look broken. I tried troubleshooting the issue by myself without any luck. What I did so far was reset my Windows fonts to default, reinstall Firefox and look what font-families are loaded through the Inspect tool. If I opened the same web page in Chrome the font looks OK. Two websites the issue is most visible at - support.fiverr.com and gmail.com when someone replies to my e-mail.

Please find below a screenshot of what I mean

I use a laptop with Fedora 36 installed. Firefox is version 104.0.1

Until a few days ago, there were no problems with video display. But since a few days, video content that is offered by the news site from NOS (Dutch television) is not displayed anymore. I only get this error: The media playback was aborted due to a corruption problem or because the media used features your browser did not support.

Also some content on Youtube aborts. For example loading https://www.youtube.com/watch?v=qq0BUiEs3JM results in this error: Er is een fout opgetreden. Probeer het later opnieuw. (Afspeel-ID: Ui0fzPxdSexgYcZ4).' (An error occured, try later again).

When using the Chrome Browser both websites can be used without giving errors implying that all the codecs are available.

How can I detect why video is blocked?

(Twitter also gives problems. After a fraction of a second, it stops displaying video)

I have turned on Hide pointer while typing in Mouse Properties, see pic. It works in Notepad, but not in Firefox.

Mouse Properties can be accessed from Windows Settings > Bluetooth & devices > Mouse. Here click on Additional mouse settings.

Although I had long ago selected "Open Previous Windows and Tabs" in Start-Up, my windows and tabs were not restored when I inadvertently quit Firefox this morning and restarted. I then went to the three horizontal bar Application Menu > History to look for "restore previous session", but that button was missing.

So I have two questions: 1. Why didn't my selected preference, "open Previous Windows and Tabs " at Start-Up work? Is there a fix? 2. What has happened to my "restore previous session button in the History tab of the Application Menu, upper right of toolbar? Has Firefox deleted the "restore previous session" button? Can I reinstall it in some way?

I'll be grateful for advice. Thank you

Well, I wanted to provide PRIVATE feedback to the developers, but it appears that they are intent on avoiding that at all costs, continually steering me into posting on the public forum instead by not providing any other alternative. So be it. Remember, this was not my choice.

I was shocked to see the following results from Firefox's own presearch for the simple term "mom" (I was typing a longer word, but the presearch came out during my typing). I think your curation algorithms need some hard tweaking.

I have 2 laptops I will call OLD and NEW. Both have Firefox Browser 104.0.2. I have the Menu Bar at the upper left corner for both OLD and NEW.

On OLD when I click the Bookmarks link in the Menu Bar, i see a few links (Manage Bookmarks, Bookmark current tab, etc). Then below the links I see all my bookmarks listed. I DO NOT have to click on a link to see my bookmarks.

On NEW when I click the Bookmarks link in the Menu Bar, I also see a few links (Manage Bookmarks, Bookmark current tab, etc). And then nothing else. I have to click a link to see bookmarks. How do I get NEW to display my bookmarks without having to click a link?

Hi all, is expired cookies management changed lately? Authentication doesn't work anymore in following use case. Question is all about FF for windows, while usually I'm on FF Android, Edge and Chrome for Windows and all these browsers are working correctly.

My working web app (static blazor wasm standalone) is interactively authenticating in Azure AD B2C using Microsoft.Authentication.WebAssembly.Msal library (like MSAL.js), API is an Azure Function protected through AAD B2C.

Login request successfully invokes Signin/Signup B2C flow with popup to myb2ctenant.b2clogin.com but breaks navigating to auth protected pages or backend apis.

From DevTools I see that every request to following b2c endpoints sets an expired cookie (expired 10 years before, year is now 2012):

When user clicks login: GET /myb2ctenant.onmicrosoft.com/b2c_1_sinsup/v2.0/.well-known/openid-configuration

Returning from login confirmation: GET /myb2ctenant.onmicrosoft.com/B2C_1_SInSUp/api/CombinedSigninAndSignup/confirmed?rememberMe=false&csrf_token=xxx

for example: Set-Cookie: x-ms-cpim-trans=; domain=myb2ctenant.b2clogin.com; expires=Fri, 14-Sep-2012 12:46:46 GMT; path=/; SameSite=None; secure; HttpOnly

FF registers this warning in console:

Cookie “x-ms-cpim-trans” has been rejected because it is already expired

Following when MSAL execute a request to /myb2ctenant.onmicrosoft.com/b2c_1_sinsup/oauth2/v2.0/authorize?xxxx

Response always contains:

Location: https://blazorapp.xx.web.core.windows.net/authentication/login-callback#error= interaction_required&error_description=AADB2C90077%3a+User+does+not+have+an+existing+session+and+request+prompt+parameter+has+a+value+of+%27None%27.%0d%0a

All other browsers are working... Thanks in advance for any help

I just upgraded to a 4k monitor and the blinking cursor is so thin I can not see it. I have adjusted the thickness in windows 10 with took care of the issue with Microsoft applications but I can't figure out how to make it thicker in Firefox.

I've tried changing from Firefox theme to System theme but there was no change. Fonts is set to Segoe UI 17.

I have System theme -- auto enabled.

Any suggestions?

My FireFox media player was working fine this morning. Now it will not play the mp3 files I need to play for my work. Also, there's no sound on YouTube when I use FireFox. I have system sounds on my computer, and I have sounds on Google Chrome, but there are no sounds on FireFox. The media player will open with the mp3 files, but it does not move or play at all. I disabled my antivirus and it still won't work. So that is now fully back on. I uninstalled and reinstalled, restarted my computer, I have done so many things over the last 4 hours and nothing is working. There was a Windows update today that happened shortly before this problem occurred.
