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.

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.

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?

When I open my emails, I get an automatic default to email REPLY. I cannot open my emails for reading and attachments. Also, I no longer get the time of the email listed. How do I restore my settings?

Hi there,

I'd like to know if there is a way to remove firefox relay from the context menu, as per screenshot. I really like the relay icon on the email fields, but I don't want it to show on the context menu and I found no such option on the relay extension. Is there a solution to this?

Thank you

My display is too big now and I lose parts of webpages in the "edges"? Search bar when I first sign on shows 120%. How do I get back to 100%? Please no technical jargon. If I can't fix this,will have to quit using Firefox.

As you can see in the attached image the highlight is coming out grey instead of blue, which is what is showing when I select 'save screenshot'. It used to be this error happened maybe one in 20 times and it was annoying because I am making these screenshots for use in youtube videos and it becomes unreadable, but now it is every single screenshot even after doing it dozens of times and with different pages.

Whenever I m visiting to my website I m facing an issue like getting a horizontal black line near the scroll bar, it is coming up when I make my browser window responsive to the resolution of 1920 X 1080 and when the zoom level is decreased to 90%, 80% & 67%.

This issue I m not facing in other browsers like chrome, edge.

Below is the screen shot attached,

When I see a highlight reference to browser settings: Java Script enabled; otherwise Firefox wont operate properly. How to know Java Script is not enabled (vice-versa). I'm not sure that I have seen a switch Or toggle to know JS is On/Off

Few days ago I started to have issues with Zoom Meeting recordings playback. When I open the video it clocks but doesn't start playing. I never had this issue before. Zoom support cannot replicate this issue. They say everything works for them.

I cleared cache and history, restarted my computer but that didn't do anything for me - video still clocks. Playback works fine on Chrome. Somehow playback on Firefox stopped working for me. I am using the latest version.

Please help
