Hi. I have about 15 home pages set to open when I open Firefox. I read the news, catch up on a few sites and have various jobs and tasks to complete. But whenn I've don all that, and close down Firefox, each time I open Firefox again to search for something etc, all 15 of my startup pages open up and I have to manually close them all down.

On Windows 11, all I need to do it right click the firefox icon and select open new tab. This is great, it opens Firefox with just a single new tab open. But on my iMac, this option is missing.

How can I re-open firefox with just a blank tab - or even just one specific page like Google?

I cannot access https://www.ebay.co.uk/ with Firefox. Just get a blank screen and it never seems to load. I can access other sites ok in Firefox and I can access it in Edge. I ran the refresh option to disable all plugins and it didn't fix it.

Hi there,

I have a question please :

I can check the candidate type ( webtrc ) in Edge with this simple command : edge://webtrc-logs

Can you please let me know how I can check it in Firefox. I`ve searched the web but I couldnt find the answer.

Thank you in advance.

Hello. I just set up a self hosted firefox-syncserver on my homeserver.

I created a virtual host on nginx which looks something like this: firefox-syncserver.mydomain.com and have a mariadb database as the backend. In about:config on firefox, I then set the identity.sync.tokenserver.uri to https://firefox-syncserver.mydomain.com/1.0/sync/1.5.

Everything seems to work fine, but I still have some questions which I did not find an answer to online.

   Since I have this public accesspoint for my syncserver now, can not anyone just use it? What stops them from using my url (https://firefox-syncserver.mydomain.com/1.0/sync/1.5) in their about:config?

   What is the SYNC_MASTER_SECRET for which I set to a 256-bit random key?

   When I navigate to https://firefox-syncserver.mydomain.com/1.0/sync/1.5 in my browser, why does it say {"status":"error","errors":[{"location":"body","name":"","description":"Unauthorized"}]}

I would really appreciate a good answer, as I could not find anything good about these points online.

When we select one of the context menu to copy the Image URL, for example, when you re reading in the page below, https://en.wikipedia.org/wiki/List_of_paintings_by_Pierre-Auguste_Renoir;

and selecting one thumbnail like as I attatched, we expect Firefox returns like URL below. https://upload.wikimedia.org/wikipedia/commons/thumb/2/26/Swing-Renoir.jpeg/200px-Swing-Renoir.jpeg

But actually, Firefox sometimes returns like this "blob" url. blob:https://en.wikipedia.org/e7b597f6-ea69-4cc2-aa37-07cad9e66a7d

This is not what I expected and desired. Do you have any idea of the cause and solution for this situation?

Have multiple websites written in HTML which have always functioned well. EX: uscourt.com; medical-malpractice.com Now when opened with Firefox (not with other browsers), multiple aaaaxxx appear in front of many lines in text. Cannot get rid of such. Screenshot attached. Please advise. Thank you. Judge Rein JudgeRein@uscourt.com

My computer crashed and I lost my Firefox browser settings, history, bookmarks, etc. Had to reinstall the the whole thing. I suppose there may have been a way to get everything back, but I didn't have access to that info at the time. I transferred my bookmarks from my other browsers to Firefox, but they just show up in a folder. Is there any way to transfer all of it so that everything shows on one list, without moving each one line by line?

I've attached an image of what's happening to me. Since last update, the toolbar is 50% allocated to blank space which cannot be used.

For example, I cannot drag to resize the search box across to the left side of the toolbar (which is where I like it), nor can any item be dragged or placed there.

I'm pondering (if I know how) installing an older version and preventing updates etc.

Is there another solution? Is anyone else seeing this?

Any tips would be hugely appreciated.

Cheers, Matt (Australia)

I use a Royal Kludge RK 61, where the back tick ` character, requires pressing the Windows key + another key. This works everywhere else, but Firefox. Is there any option to fix this?

I looked through some other threads related to playing around with the ui.key options, but nothing there helped. And most of those were related to the Mac Os as well.

Thank you.

Hi :)

I use Firefox on my Asus laptop running Windows 10. It's one of these laptops with both integrated and dedicated graphics (Intel plus Nvidia).

I often experience this issue when putting a video in full-screen (especially when viewing trailers on Steam, but this may just be because I mainly use my Windows laptop for gaming, and thus most of my video consumption here is from steam). This screen will briefly (for less than one second) turn black and audio will pause before the video appears in full-screen, and playback resumes normally.

It "feels" like a GPU switch is taking place, I'd assume from the integrated graphics to the GeForce card. This is not the proble. The issue appears when I return from full-screen mode. I always have several Command Prompts open with SSH connections to my Linux server and sometimes my MacBook Pro. These windows are now empty. That is, all text is gone, and I can no longer interact with the sessions. They're not "broken," as in they're not saying "Not responding" and don't ask to be forcefully closed, they're just black windows with borders around them. All I can do is close them all down and open new ones to reconnect and start over from where I think I remember I was.

I should note that this doesn't ONLY happen with Firefox videos going into full-screen, it has also happened after launching a game and returning to the desktop. This strengthens my belief that this has to do with GPU switching and/or video "mode" change(s).

Assuming I'm correct (my IQ is 5,000 and I do do the very big brians), is there any way to control how videos go into full-screen in Firefox? Or "lock it" to a specific GPU? I've rummaged through about:config and haven't seen anything that seems directly relevant.

I've already tried using the Windows settings to tell the system that Firefox.exe should use the integrated Intel graphics only, but this has no effect.

I remember I used to use "Media Player Classic" many years ago, and it had a slew of options of how to render full-screen video. IIRC, it had stuff like "Overlay," "Windowed," "Windowed borderless," "DirectX," etc. This make me wonder if there's multiple ways of chosing how to render video in full-screen, then maybe one could direct Firefox to use a different one than the default and my problem might disappear? Or maybe one could tell Windows that if an app wants to go into full-screen video mode, Windows should pick a specific mode for it?

I'm not a Windows developer, so I don't know :) But I'm hoping someone has a good tip, because I'm finding myself using this system more and more, and this is my biggest problem with it currently.

Thanks in advance :)

Hi everyone, I've recently reinstalled Firefox on two new computers and have had the same problem for each: My extension/add-on icons have disappeared from my toolbar. I've tried adding them back, but they don't appear in the options (see screenshot 1 & 2). My navigation is not set on "always private". Here's what I've done so far: 1. Checked if others have had my problem. 2. Uninstalled and reinstalled all my add-ons. 3. Set the view settings to default. 4. Reinstall Firefox. I'm having the same problem on both computers. Thanks in advance!

Hi lovely guys, I got a message from the Firefox Monitor that my email + more has been exposed in a data breach. This supposedly concerns my account with a certain Eye4Fraud. But I have no account with them, have never had anything - anything - to do with them, so I am puzzled. Is there somebody else using my email for their account?

Kindest regards, Reginald Copeland

I'm a commercial real estate appraiser who uses CoreLogic's SwiftEstimator online service to generate replacement cost estimates for commercial buildings at https://www.swiftestimator.com/Main/Default.aspx .

As of a couple of weeks ago, I can no longer generate new reports using Firefox, and a CoreLogic customer rep at (800) xxx-xxxx or email is. xxx @corelogic.com told me the reason for this was a "security issue" with Firefox and that until Firefox corrected the issue I would have to use the Chrome browser, which means that I have to download Chrome for every report and then uninstall it afterwards.

Will Firefox please contact CoreLogic about the SwiftEstimator "security issue" noted above?

Thanks -
