Firefox-Hilfeforum

After a forced shut down, my home page is suddenly blank. All my tabs are missing. All my most used links are missing. All the reading suggestions and pocket is missing.

Is there anyway to restore these items?

This has been bugging me for ages. Happened on Windows 10 and now on Windows 11.

I start watching some video on YouTube or whatever, decide it's not useful/what I want, stop playing it, close the tab or navigate away, but if my device locks, the controls for this old, discarded video, that I didn't want to watch, are on the lock screen.

I wouldn't mind if it was a video I was currently watching but it's somehow remembering the last thing I started to watch. I can see no hint anywhere else that it's still active in any way at all.

The only way to get rid seems to be to close Firfox.

This is very annoying because it seems you can't watch anything without Firefox remembering it and putting on the lock screen until the end of the session, so it could be cluttering things up all day unless I close everything and (in my case, because of prvicy settings) delete cookies and log myself out of most sites.

I've tried multiple searches but all I've found here is a post about turning off media.hardwaremediakeys.enabled but I don't actually want to do that, I just want Firefox to forget videos when I've closed the tab or navigated away from them.

Elsewhere I found a suggestion to disable dom.media.mediasession.enabled but that setting isn't found.

Any help much appreciated.

Apologies if I'm repeating a previous request - couldn't tell if it was submitted.

I'm running Windows 10. While changing the startup screen somehow an image I thought was deleted appeared and now is frozen, apparently on top of a Firefox window. I've rebooted, restarted and followed the Windows help suggestions with no success. Right now I don't know whether this is a Firefox or Windows problem. I updated Firefox today to the newest version before this happened.

Any help will be appreciated. I can open new Firefox windows.

P.B.

I have two questions:

1. Will WASM and JIT be turned on or not affect the operation of RLBox?

I currently have the following about:config settings set to false, I'm wondering if this will cause the RLBox to not function?

javascript.options.ion javascript.options.baselinejit javascript.options.native_regexp javascript.options.asmjs javascript.options.wasm

I hope Mozilla staff will consider listing the operating status of RLBox in about:support, so that it will be clear at a glance.

2. Enabling "security.sandbox.content.shadow-stack.enabled" will cause add-ons to not function properly.

This setting seems to have been around for a long time. Is there any progress on this? Chrome has supported this feature for quite some time.

I would be grateful if you could help clarify this and inform me of the answer.

After one of the updates a few months ago, I have started to have trouble with firefox. After a while if I try to open a new tab and type in a link, the tab will try to load forever and I will not be able to open any more as doing another tab and typing a new link will have the same problem. I found that at first I could close the browser and reopen it to have the tab fully load and refresh whatever was already open, but after a bit that started to have an issue too. Most times now if I shut down and relaunch firefox within a few minutes the browser will open with all of the tabs open but they are all blank, with no links filled in, pages loaded, or anything. If I close and reopen after that then it only opens with a "new tab" page and everything that was open is lost. None of the more recent updates for firefox have seemed to fix this issue.

Thank you.

Unlike opening a regular new window or even just opening a new private browsing tab in an existing window, when I open a private browsing window, the address bar isn't auto-selected. I know I can use 'Ctrl+L' to select it but that's not a habit I've been able to train yet, and doing so would be much more frustrating than just using firefox in a more intuitive way. How can I change this? Is there anything that can be done? I can't find any relevant setting when digging into the 'about:config' section, nor in any of the regular app settings.

Hello. I have window10. I have primary password which must entered before accessing any site. or the last 3days my computer asks me repeatedly to enter my primary password. and the circle goes on.

So I am unable to use my computer.

I was searching for a support phone number to explain myself better. Sadly I could not find any number. Please help. Thank

Hi. I just hoped on my computer and firefox seems to not want to load any site. Somehow this support page is the only thing that seems to be working. My other browsers such as Chrome is working perfectly fine, I'm able to search whatever & watch videos no problem so it does not appear to be a wifi issue...

Everything I search on firefox leads to a blank page that doesn't appear to be loading no matter how long I leave it for. The menu button in firefox does not work either

I've tried: - Restarting the computer several times - Turning off Anti-Virus - Clearing cookies & data

I've attached screenshots of what it looks like whenever I try to search for something... Looking to hear of any solutions you may have!

This site:

https://www.treasurydirect.gov/log-in/

When you click "Next" button it opens in a new tab the following URL:

https://www.treasurydirect.gov/RS/UN-Display.do

Produces a "page not found" error. Works perfectly on Chromium, Chrome & Vivaldi.

Hi! After a routine update today to Mozilla Firefox 127.0 for Linux Mint, Firefox is asking for my master password before letting me continue. Sync does not appear to be enabled.

I'd really rather it didn't do this, because my password manager is now always open and accessible. Previously, the master password request was only triggered when I came on a site that needed a password.

Anything I can do to fix this?

Thanks for any pointers!

My Problem: When I open any Dropdown for my Favorites (including the Bookmarks arrow on the left) it leaks past the Firefox Window and behind my Windows toolbar (When Using DisplayFusion only, more on that later). Some items then become unreachable: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-06-15-08-17-53-5a6e2c.png

This does not happen with the settings dropdown. It correctly stops at the toolbar: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-06-15-07-57-17-2e5d8a.png

What would fix the problem:

• The behaviour of the Favorites dropdowns should be the same as the Settings one in my opinion.
• I would be fine with dropdowns staying inside the Firefox Window at all time.

Note on the cause of the problem: Using the default Windows ToolBar makes the dropdown go OVER the ToolBar: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-06-15-08-17-14-bc7e78.png

However, I am using a software called DisplayFusion that overrides Windows ToolBar for extra features and customization. The dropdown goes behind DisplayFusion's toolbars. I will also ask the devs on their side for a solution but I still think the dropdowns behaviours between Settings and Bookmarks on Firefox should be the same.

Thanks!

When i open https://provider.transporteg.com/ this website and login in the portal this is not showing the bidding running time and processing time . please solve this.

I am currently using Ubuntu 24.04. I recently switched from the snap ubuntu package to using the firefox APT package. However, I've noticed this really weird issue. Whenever I download a file, it always seems to have the "file://" link or mime type.

Say for example I download an mp4 video, trying to open it via firefox results in a dialog asking me to "select which application i want to open this file link in"

I have tried refreshing firefox, and tried completely removing it from my operating system (a search of my entirety of / showed no traces of anything relating to firefox), but even after a clean install, the issue persisted.

The only way I found that can fix this issue is by using firefox nightly, or using the firefox flatpak. And I'd prefer to not use either.

I was monitoring the browser console, and upon clicking on the file in the downloads list, It seems that firefox gets this error:

Uncaught (in promise) TypeError: defaultButton is undefined

   _setInitialFocusIfNeeded chrome://global/content/elements/dialog.js:318
   _postLoadInit chrome://global/content/elements/dialog.js:332
   connectedCallback chrome://global/content/elements/dialog.js:149

dialog.js:318:9

This error does not occur on firefox nightly.

I believe I have troubleshooted this as much as possible on my end, and I'm unsure of what to do about this. Could I please get a bit of help?

Versions: Firefox: 127.0 (64-bit) Linux: Ubuntu 22.04.4 LTS

Description: After some time, and (under unknown conditions), the input delay will shoot way up. Like 20-30 seconds.

Strangely enough, this only applies to keyboard inputs. I can change my tab with my mouse, I can click on things, no issues there. But any keyboard interaction is hugely delayed.

This does not fix itself until I close my browser and restart it. Closing the browser is always broken here too, if I close the browser with the [X] exit button, I then need to kill the process because it just hangs. It blanks out the contents of each tab like it's preparing to close them, but it just doesn't ever complete the task without a manual kill.

CPU usage and memory usage are relatively low; significantly below my system's limits.

I've already tried this suggested fix, to no avail.

The frequency of this is only about once a week at most, usually once a month, so it's not a huge issue, but I'm just worried about this occurring during a critical meeting or something later. Having this impending restart needed is kind of worrying for critical usage times.

I'm working on developing a website that uses WebGL in it, but sometimes some bad code will cause WebGL to crash. The issue here is that once that happens, I have to go into troubleshooting mode and back out before it starts working again. Is there any way to make it so that WebGL works after it crashes?

i use Firefox as my browser, but AT&T Yahoo is my internet provider so I use a Yahoo home page and Yahoo mail. Last week they did an update, now every time my laptop goes to sleep I have to re log into Myyahoo to get my mail and my home page. It also seems to log me out of some of my other forums and websites at the same time. I'm not sure how to fix this in settings so any help would be great.

I have 2 soundcards on my iMac, (OS Ventura 13.6.1) : one internal (iMac) and one for music production. (universal audio)

Until the latest update (127), I could select either one and I could hear the audio from Firefox. But... since the update, only the internal iMac audio card is working. Note that I don't have this problem with Safari nor Chrome and it used to work on Firefox until the last update.

Anyone has noticed that? 

Does anyone knows how to contact them and log this as a new bug?

Thanks all!  :)

Issue Summary: When using a maximized Firefox window with the Windows taskbar set to automatically hide, the taskbar sometimes fails to appear when moving the mouse cursor to the bottom of the screen.

Thank you for your attention to this matter.

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.
