My issue is that if I access the upper right corner of the screen, titled "Open Application Menu" and go to Settings I'm told my Browser is not the default AFTER THE PROCESS OF JUST MAKING IT THE DEFAULT.

It seems there is an effort to try and drive all of us nuts. This never happened before, and if it continues it will be the end of electronic communications (which it is suspected is the plan by those who engage in violence to achieve their objectives).

What I came here for was to have my settings, after the process (done many times previously) show a response in Settings that, "Yes" my browser (Firefox) is the default, which it did for a time today. Obviously there is no persistence.

When I got help on this issue previously, my response was I already tried that, and it didn't work. There used to be a lot of different browsers. Now I haven't come across any of them currently. Some are having great success in seeing to it that only their browser will survive. That seems like a "gangland" type of mentality to me.link text I believe I spent enough of my time on this issue and explained it in detail. There's really nothing else I can "contribute".

I, by the way, went to my Internet provider today who found an email under Preferences that she said had the capability to steel my emails. It had an extension in Australia (*.AU). If that has anything to do with this problem I'd like to buy a pair of handcuffs to see if that individual(s) being constrained from using a PC keyboard is a cure for this problem.

Hello,

I'm experiencing a visual issue when typing in text input fields (such as input boxes or textareas) in Firefox. While typing, a dark overlay or block appears behind the current word or text I'm typing, which makes it very hard to read. It looks like some kind of highlight or shadow, possibly related to spellcheck or text recognition.

This issue occurs across different websites and makes it uncomfortable to type for long periods. I'm currently using Firefox [137.0.2] on Windows 10.

I've attached a screenshot that shows the problem clearly.

Things I've tried so far: - Disabling spellcheck - Changing themes - Disabling extensions - Testing in private window

None of these solved the issue.

Notably, switching to the **light theme** makes the issue disappear — the text input background becomes clear and easy to read again. However, I prefer to use the **dark theme**, so I’m looking for a solution that works in dark mode as well.

Can anyone help identify what's causing this or suggest a way to disable this effect while keeping the dark theme?

Thanks in advance!

I cannot tile my Firefox windows to left or right when I choose vertical tabs mode from settings. It works fine with horizontal tabs enabled. I am using Firefox 137.0.1 on Linux Mint 22.1 Cinnamon 6.4.8 with Linux Kernel version 6.8.0-57-generic, display server X11.

I am using the latest version of Firefox and I can not log on to facebook.com and I get a graphic with Oops somthing went wrong (see image). This has started happening in the last couple of days since I updated Firefox..

I can login in Chrome without a problem I have disabled all add ons My cache has been cleared My history is removed when I exit Firefox. I have not changed any firewall settings.

Is anyone else having this problem?

Hi

When I browse to https://earthobservatory.nasa.gov/images/154162/clouds-hover-over-the-alaska-peninsula, I can play the shown video once.

When the video is about to start the 2nd time though, the log from the web developer tool says (see screenshot): ``` Media resource https://eoimages.gsfc.nasa.gov/images/imagerecords/154000/154162/ak_cloudwave_vir_20250407_anim.mp4 could not be decoded. clouds-hover-over-the-alaska-peninsula All candidate resources failed to load. Media load paused. clouds-hover-over-the-alaska-peninsula Media resource https://eoimages.gsfc.nasa.gov/images/imagerecords/154000/154162/ak_cloudwave_vir_20250407_anim.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) Details: virtual RefPtr<MediaDataDecoder::DecodePromise> mozilla::GMPVideoDecoder::Decode(MediaRawData *): mGMP not initialized ``` and the video shows the warning "No video with supported format and MIME type found.", although the video was successfully played the 1st time.

Note that the first four warnings in the screenshot already appear when loading the page, i.e. before playing the video the 1st time.

The same happens when all installed firefox plugins are disabled.

I am using firefox 137.0.1 (64 bit) on arch linux.

Thanks for help, Chris

I've been using Firefox in Windows for years as my default browser. Suddenly tonight, Microsoft Edge became my default. When I go into Windows Settings and try to change back to Firefox, Windows offers me only Microsoft browsers as alternatives (or offers to let me into the Microsoft Store): Windows Edge or Internet Explorer.

The Control Panel / Settings page "Set Default Apps" is the only way that I know that Windows lets users set default browsers, but it suddenly seems to be restricting me to only MS browsers.

Firefox works normally in every other way, but warns me now every time I launch it that I have a different default browser. When I click the button in the warning (or in Firefox's Tools / Settings) I just get put back to the Windows "Set Default Apps" page, which, again, only lets me choose Microsoft browsers.

What could have happened? I haven't altered my Firefox configuration or installed extensions or plug-ins in a long time. If I uninstall & reinnstall Firefox, will I lose my many configuration & interface settings and will I have to reinstall all my extensions -- or will the reinstalled Firefox remember its existing configuration? Or would that probably not help at all.

I'm very computer-savvy, but have run out of ideas. Can you help??

Hi, I need to know how to activate the toggle button for Autoplay on the YouTube Music browser page. There is only an "Autoplay is on" notice but no way to turn it off. It exists in Chrome (yuck) but not in Firefox. Please save me from what some AI bot thinks is my music preference!

Thank you, Trish

I've suddenly started to get a box appear when I open Firefox, entitled User Account Control, asking 'do you want to allow this app to make changes to your device?' I don't know why, and don't mind ticking yes box but I'd rather not have it keep on appearing. I found one suggestion - go to Settings, General, Firefox updates and tick auto install. But this box was already ticked. How do I stop this box appearing? Many thanks.

I've been noticing that on some websites, certain fonts are hard to read. For example, the letter "e" being too bold or "i" looking like an "l", and "c" sometimes looking like an "o". Those are just a couple of cases. I've attached an annotated screenshot to show this issue.

Hi

Could you assist here please?

I encounter a bug, which youtube website still loads normally. The problem occur when I tried to open one of the youtube video and it just a black box with no normally youtube playback button, but the recommendation can be view as I scroll further down. Entering in-video mode, cause it to going back previous page but no small video playback at the corner.

Normally, I would think my internet was a bit slower, but opening youtube in chrome or other browsing software have no such problem. I try watching Netflix on firefox, and it just works fine but the youtube things still occur.

Thank you.

Hello there! I have Firefox on both my (Windows) laptop and (IOS) mobile device. Several months ago (January or February, maybe?) I had to delete Firefox from my laptop and reinstall it to fix an issue. No big deal. However, whenever I check my synced tabs on my mobile device, it still shows the tabs from before I uninstalled it on my laptop as well as the taps currently opened on my laptop. It appears as if they're two separate devices. I already checked the "Connected Services" section of my account settings, and my laptop does not appear twice. I was hoping someone could point me in the right direction of how to remove the previous version of Firefox from appearing on sync on my mobile device. TIA for any help!

My Sync is all fouled up and I don't have a valid recovery code: 1) How do I erase all traces of Sync from my laptop, my Android phone and my Android tablet? 2) Exactly how do I set up Sync again? 3) How do I generate a new recovery code?

Thanks. After using Firefox for years, I still have trouble with the little things.

I recently updated my wife's computer to an Apple Mac Mini M4 running iOS 15.4. Everything seemed to be working fine including Firefox until yesterday when Firefox update box popped up. She did as she normally has for years of using Firefox and clicked the restart for update button . FF restarted and popped up with 2 dialog boxes one asking to check network for there devices which she click "Don't Allow", she only uses that computer no smart phone etc. Then a second dialog box asking for an admin login and password to install something else I put in my admin login and password clicked continue it doesn't seem to do anything except lock up Firefox to the point I have had to re-install her user from a time machine backup 2 times in 2 days. I tried installing a new copy of Firefox that will launch the issue is she's used Firefox for probably 10 yrs so there are ten years of bookmarks and logins and passwords saved in the original copy of Firefox that will no longer boot unless I do a complete user re-install from a time machine backup.

Please help, how can I fix this problem?

This is from User: Paul C. I have posted about this issue before. Last week!

This problem has returned after the clean installation of Firefox again and Firefox did more auto-updates. See attached files from the search bar "Information con(circle with the letter i inside) says I do not have a secure connection! I am not choosing to have an insecure connection. I rely on my ISP, Firefox, Windows Defender, and my VPN to make sure I have a connection that is safe!
