Firefox Support Forum

When trying to play videos on my laptop they look terrible. The video is completely blown out and doesnt apear as it should. When turnnig on the troubleshoot mode it fixes it but then the video becomes choppy. I cant attach a photo because it looks normal when a screenshot is taken

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 installed Firefox at work and set my personal email address as secondary to my business address. Well, I liked Firefox so much that I decided to use it at work and at home - and I removed my personal email from my business account. Unfortunately Firefox is still recognizing my personal email as the secondary address for my business account and I am completely incapable of making a new account. My bookmarks and saved passwords are all different between home and work. I NEED two individual accounts, just like how I was using my browsers with Chrome.

With the latest update to Firefox (116.0.1) typing anything in the search bar looks as though my keyboard is mapped to everything - every keypress does something different. This only affects Firefox, no other program behaves this way (Word, Excel, Discord, etc.).

Currently running Windows 10, AMD Ryzen 7 1800, DDR4 RAM, Malwarebytes, and ZoneAlarm Extreme Security version: 15.8.139.18543. Had to revert back to Firefox 113 to type this via downloading it via Edge.

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?

I'm using the latest version of firefox, at the moment i had a trouble. Text of timeline zone of my facebook hidden, first timeline unhide but other timeline hidden. I'm restart my firefox, remove and resync ... but this error continue. I'm try other browser as chrome, brave no error. How to fix it? I'm the fan of Firefox but user experience too bad with this error I'm upload some images screenshot with error and no error with chrome browser. ++

Usually when I start my browser for the first time, I have the Firefox homepage only. For two weeks ago, suddenly an extra tab show up when starting: A page with a commercial for installing "Avast Online Security & Privacy (Add to Firefox-button)".

I use Avast, but I don't want this add-on. And I certainly don't want that extra tab every time I start my pc.

I have three times searched for a solution all over in the Mozilla & Avast settings and on the net: I should go to "Add-ons and themes" - "Extensions" - and on the list "Manage Your Extensions" I should remove this add-on - but it's not there of course, because I didn't install it.

So how do I remove this tab from showing at start-up? (Google Search can't help) Appauling that someone put this tab on my pc in the first place. Both Avast and Mozilla have other ways to communicate with me about that add-on, if needed. Now I had to shut it down every day for two weeks, because I was way too busy to write you until now.

Hope you can help me.

Since Ebay changed their format for auction ads the photos that are part of the ads open as faint negatives that can barely be seen. However, if you right click on one and save to a new tab they are fine.

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 ?

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

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 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.

my older asus laptop had a critical failure and I needed to get a new computer and to my understanding when you have had a Firefox account for as long as I have you should be able to sync your whole account to a new device to my dismay that is not the case and I have years of bookmarks and history on my account urgent fix would be appreciated.

Hello:

I have 2 profiles in use. 1 for personal use with their respective bookmarks, passwords, and extensions, and I have no trouble syncing with this one. However; profile 2 that is for work use that has its respective bookmarks, passwords and extensions, has become a nightmare.

It happens that I have both profiles on the same computer and when trying to create an account in Firefox, the system asks me to enter the email registered in profile 1, with the warning that bookmarks, passwords and extensions will be mixed.

I mention that I have migrated from Google Chorme to Firefox for speed reasons and because I use windows 7 (I don't like later versions) Now well; in Google Chrome you could create as many sessions as were registered but in Firefox you can't.

Oh! I have been working fine with Firefox but suddenly an error occurs (it has happened to me 2 times in the last 2 months) in which the program closes and all the data of my profiles stored on the pc DISAPPEARS or is deleted (including cache), when I want to open them again:

firefox.exe -P

Then I have to give myself the task of synchronizing profile 1, but profile 2 I have to be importing from my previous Google account or importing a backup Bookmark.

The option to copy and paste the data from Firefox to replace it in the path (supposedly brings with it the data of everything):

C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\308046B0AF4A39CB

with Firefox turned off it has not worked for me. Since when opening I see 2 profiles called Default "X" and Default "Z" without data.

This is a headache that if it happens to me, it happens to millions who have 2 or more profiles.

Why can't I sync a second profile? Why do you insist that there can only be one sync per device? Is there a solution for this?

Note: I have read all the tutorials out there and the situation remains the same. Synchronization with 2 or more profiles is never described.

Thank you very much to whoever asked this question!

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?

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?
