I don't like Firefox videos showing up in my media player controls, so I turned off media.hardwarekeys.enabled, but it doesn't seem to do anything anymore. I'm pretty sure it used to work at some point, don't know when it stopped working. Even though I have it turned off, videos still appears in the Media Player on my panel, and I can play and pause them with the play/pause button on my keyboard. I have also tried disabling dom.media.mediasession.enabled, but that doesn't help either.

KDE Neon 5.27 Firefox 113.0.2

When I right click a tab I do not get the option to "Send Tab to Device" that I am used to on Windows. Is this missing from the Linux version? Or is there a setting for it?

I have searched the internet for this problem and could not find such things. I would appreciate any help!

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

Last week, mid-day one day, videos on YouTube suddenly all had a warm cast --yellowish for color, cream/beige for B&W. I have researched the issue as I can. It is not my Windows night light; my drivers and PC are apparently all updated; everything is working fine. I checked to see if the same happened with Vimeo videos and it did. I'm running W10.

   Interestingly, the pop-up thumbnails one gets when hovering over the timeline as not affected; they look fine.
   One post by someone else was answered that it was a GPU driver issue; another said it's only with HD videos.
   I'm a B&W photographer and would really like to get back to normal again. 
   Any ideas?

FF 113.0.2 Win 7 64 Bit

When I read a pdf online it gets downloaded even though FF is set to always ask. When it asks I choose open with FF or open with Adobe Reader . Both downloads the file to my download folder. It doesn't ask what foder to download to even though I have FF set to ask where to download to in settings/general

I tried setting browser.download.improvements_to_download_panel to false as here https://support.mozilla.org/en-US/questions/1370494 but it didn't help

Hello, Firefox always downloads a pdf files from e-mail attachments, whether I open it in a browser or with acrobat reader. So, if I open the same file every time it goes to download folder with multiple clones, like example file-1, example file-2 etc. I've used every combination of options, but the result is always the same. I've refreshed Firefox, but nothing changed.

Please help me with this case.

I have a 2020 Mac Mini with Ventura 13.2.1 on it. I have four virtual desktops which are part of the OS. I place various apps on the others like stocks and weather etc. to diminish clutter on screen. Firefox shows up on all 4 of them. I want it on only one desktop. Safari works on only one and doesn't show in the other 3 desktops. I have searched the net but haven't found anything that speaks to this in particular. Thanks for any help with this and I hope it's just a simple setting. Regards, Jim Stephens

I had to reinstall windows 10 (this was done by Microsoft with my permission) and so firefox was uninstalled (long with all apps). i have reinstalled Firefox, but can't retrieve my old bookmarks. I have a file of very old bookmarks, but the "import/restore" function doesn't restore or import using that file. Help please. Can the up to date bookmarks be retrieved from my uninstalled Firefox?

Hi,

I recently added ESET Password Manager as an extension but I was unable to log on and use it on my laptop. In a nutshell, to be able to log on and use the extension, I needed to install the app on my phone as well and sync between laptop and phone did the rest. This solved the login issue however, there is no icon on the toolbar for the extension and if I want to use the Password Manager, I have to do it on my phone.

Any ideas on how this could be solved? I have reinstalled the extension numerous times, tried troubleshooting mode as well but that is not useful with add-ons..

Thanks S

This happens only on Firefox and Firefox Developer Edition on one of my PCs and not the other. Firefox is version 113.0.2 (64-bit) and DE is 114.0b9 (64-bit)

Anyone experienced this before?

Since probably 3 or 4 weeks ago Ebay through Firefox has been terribly slow. I have selected the option not to track in the address bar and still the same problem. I run ebay through MS Edge and runs perfectly. Happens to me in 3 out of 4 computers. Only in 1 works ok, very strange...

Speed connection in all of them is at least 200mb/s

Thanks.

Moin all,

since some several weeks I'm facing a real anoying problem. Every Youtube (and other platforms) Video shows extreme brightness. It looks like as someone recorded the video directly in the sun. An example is the best so I attached a Photo with FF in the top left, Chrome in the top right and Edge at the Bottom. Only the frames have been a bit cropped for privacy.

The video shown in the screenshot can be found here. Today I also tried a fresh installation of my Win 11 and also FF (Had some free SSD around for that). But this had no effect, it looked the same. The only change I can see is when the Troubleshoot mode is being activated. But only while this mode is active. If FF is being reset or even new installation (like before fresh Win 11), no change.

Cause of this behaviour I also mentioned FF Video Stream is not HDR. The others show HDR but as not every Youtube Video can be HDR I think this is not the Problem. Anyway, I don't want to change my favorite browser which was working now for about 20 years.

Does anybody have a clue what is causing this or is it a bug?

I have noticed in the last few days that Firefox is keeping my Mac from sleeping. This seems to have started around the time of updating Firefox to version 113.0.2 which happened 4 days ago. Any thoughts on how to debug this?

My laptop died but I have been able to rescue the SSD and turn it into a USB connected external drive. I can see all data from my old PC.

I have tried to copy all of my User, Local Apps Data Mozilla Profile data folders to my new Laptop but the data does not appear when I fire up Firefox on the new laptop.

The old laptop folder was c:\Users|Phil, the new laptop is C:\Users\Phill {setup of new PC added a second L to my name}

Is this an issue ?

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

Scroll down until you find "PERMISSIONS" and find for "Camera". Click on "Settings" that is parallel to "Camera". Now, select/type all websites, that you want to give permission/access to your camera.

Never used a webcam before, but i did that... the site is there, it says allow... i'm on the website now, says webcam not found... am i forgetting something? do i even have one? i'm at the library...

Hello everyone.

I've been using Firefox for quite a few years now and I'm used to keep my pinned tabs open after closing and then opening a Firefox windows.

Yesterday I noticed that after closing the navigator with the "X" in the tool bar menu, as I usually do, the pinned tabs are not "recovered" when opening again.

This happened randomly without configuration changes involved and drivers/firefox are updated to the last version available.

Moreover, I've tested the same in my notebook and it works just fine, as it keeps the tabs open when a new window is open.

Is there any troubleshooting for this or do you have any idea what could have caused this to happen?

Let me know if you need any additional info. Thanks in advance!

i can share everything that would solves the problem. thank you in advance.

I have a website that open pop-ups automatically using javascript. That is the expected behaviour of it. So I went into Firefox options and made an exception for that site. If I go to the site and wait so it can do its thing, it opens about a few of them, and then Firefox decides that the rule I have set up is garbage, and firefox decides to ignore it and block the pop-ups from the site.

Why?

Why on Earth does Firefox decides that he must do something against the rule that the user has set up. Why does it have this completely disrespect to the user settings?

I am honestly really mad at whoever decided that ignoring an exception from the user was the default behaviour.

Now, if someone knows enough what is going on they will tell me, go to about:config, go to this obscure command and change its value, value which I can't know without coming here and ask. If I create an exception, then I am in my right to expect that the browser should do exactly as the exception has been configured.

By the way I have tried with the troubleshooting mode and still happens.

These bugs have probably already been reported but just in case they haven't there's an issue where dates can't be viewed on Facebook posts without hovering the mouse cursor over the title of the post. The other bug is the cursor often, but not always disappears when commenting on posts.
