I have set .pdf files to be opened in firefox, not download and browser is still opening those in new tab and also downloading those. What could cause this problem?

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!

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...

Hi,

I have a policies.json file that acts as a white list for me (black listed all urls and then white listed needed urls). I was wondering is it possible to create a second .json file that will act as a black list. I want to give access to a partial admin. user to the policy.json file to be able to edit the file and add websites if needed but I want a another black list running as well to block out specific websites (this one the partial admin. will not have access to).

So to start off the first question would be is firefox only limited to one .json file for policies or can you have multiple .json files (I want to call the second file blacklist.json)? Btw I use Debian and Firefox-esr.

Thanks.

I wasn't sure which category to choose. Youtube videos have a spinning with the message to try system restart if playing won't begin but it never does. The videos play fine in Opera and as far as Firefox itself, I have no problems with any other websites. I am unable to perform gymnastics in order to resolve this, but it's quite bothersome. Thank you.

Edit: Sorry, I posted this once already but am frustrated and can't figure out how to delete this one. I have not gone through starting in safe mode, etc.

Hi, I cannot use wordpress.com. When I click on "log in" it hangs at the redirect and I only get a blank screen.

(Hangs here:) https://wordpress.com/log-in?redirect_to=https%3A%2F%2Fwordpress.com%2F

I've disabled all extensions, cleared cookies and restarted, nothing seems to work. Any help would be much appreciated.

Thanks!

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.

I have removed cookies and site data of localhost in Privacy-and-security> Manage-data>

Screen goes black when some videos play - audio continues, but screen is black. I am sire this is a Firefox problem - I have successfully watched videos using BING browser - same videos go black on Firefox. I have refreshed Firefox, cleared cache, restarted Firefox - cleaned cookies. Turned accelerator off then back on - because nothing changed. Does not do this with all videos, just some - some You Tube videos play, others do not. I have Windows 10 and McAfee Live Safe - all programs are current and up to dated.

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 Team,

On the Firefox browser I am unable to find the option where in I can log in to my account so that I can sync my passwords from the old machine.

Kindly advise.

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

When I start firefox its stand loading for a short time, and then comes with an error that its was unable to load the window, retry or close it. No matter what wepside i enter to use its always the same. This happen a few days ago and have been troubleshooting my self since. now i need your own help. I have reinstalled it, reset settings, taking it off and on the firewall. Removed all plugins for it. and always come to same conclution. I got the latets installer from the wepside, to make sure its up to the newest version.

Before this issue, it ran fine, no issues what so ever. and one day i needed it was stuck on this problem.

I am useing it on a laptop. atm returned to chrome for help.

picture shows the issuse not able to load, no matter the wepside.

I am trying to move my mobile bookmarks from Firefox to Brave. I've synced them with no trouble from Firefox Android to desktop. I can see a folder in the Firefox bookmark manager called "mobile bookmarks", and it contains all my mobile bookmarks. From there, I can open them in Firefox, Brave, Edge, and Chrome. No problem.

When I click "Import and Backup", then "Export Bookmarks to HTML", I'm able to save the HTML file to whatever location I like - desktop, Downloads folder, etc. However, when I go to open the file, it only contains the Mozilla default bookmarks. None of the "Mobile bookmarks" folder is visible. The HTML file is only 11 kb.

Screenshots are attached. Using Firefox version 113.0.1.

FWIW, I've also tried directly importing the bookmarks to Brave using their import feature (not using an HTML file), and Brave does not recognize any bookmark files whatsoever from Firefox. Getting really frustrated.

console.log(new Date().toJSON()); console.log(new Date().toISOString());

// Actual output: // 2023-05-27T04:21:13.004Z // 2023-05-27T06:21:13.005Z

// Expected output: // 2023-05-27T06:21:13.004Z // 2023-05-27T06:21:13.005Z

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?
