Firefox Support Forum

Are Firefox extensions sandboxed from the rest of the operating system? Suppose I have installed a malicious extension/add-on on my system. Would it be possible for the extension to access and tamper with my operating system? I do not care if it tampers with the browser tabs or data inside the browser as long as it does not have a way to tamper with my OS. Using MacOS Sonoma

No videos on any platform will play when I try to open them in Firefox. They are forever stuck on the thumbnail image of the video, and nothing happens when I hit play. I've had this happen a couple times and was able to resolve before by installing updates and uninstalling my Mozilla VPN, but this time nothing has worked. I've tried pretty much every solution I could find online:

• Updating Firefox
• Updating my computer
• Running in Incognito
• Running in troubleshooting mode
• Allowing autoplay
• Disabling hardware acceleration
• Disabling addons
• Clearing cache and data
• Enabling/disabling DRM content
• Installing Windows Media Pack

I'm running Windows 10, and videos seem to work fine in Edge, if that makes any difference.

I am deleting or updating accounts linked to an email that was hacked. However, I cannot make changes to this Firefox account that I no longer use because the email that was hacked no longer exists. I wish to delete the account because of suspicious activity. Thank you for your assistance.

Hi, I am experiencing an issue with desaturated icons in the toolbar and tabs of Firefox. I don't think any extesion may be causing this problem and i have already tried reinstalling and resetting Firefox, but this did not resolve the problem.

I use Firefox (currently on version 127.0) and starting this weekend I noticed a strange behavior. When I initially go to the NPR.org site (and only that site) everything works fine, but once I scroll down past the first two articles all of the links on the page stop working. The cursor that usually changes from an arrow to a finger does not change, the links do not change color as they should.

This only happens on NPR.org, and it only happens with Firefox (I can use Chrome at the site works fine.) Therefore I assumed that something changed at NPR.org so have reached out to them, however, I thought I would ask your team if they knew of anything going on?

Thank you tom balent

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

I had the situation maybe a year ago. I use the Firefox profile manager.

I just updated to 127.02, and now not I'm getting this because for whatever reason, since the update, I am somehow on the beta channel, but only with this profile. I just opened two other profiles, and neither is on the beta channel, although i don't know what "Firefox is being updated by another instance" means.

I don't know if it's just a coincidence, but I'm also just noticing that a number of my addons settings have reverted to default.

Hello, I Signed into and began using a New Firefox ACCOUNT Yesterday.Today,I found that I had forgotten that I formerly had a Mozilla account which is apparently still ACTIVE from 10/14/2021. I'm confused as to WHY it's called MOZILLA... Is it called Firefox or Mozilla for this Browser... and I don't want two Accounts... so I need to eliminate one. My iMac is Auto inserting My Password and I'm not familiar yet with whatever Browser I have, to locate a way to see the Password it signed me in on... ? the one I created yesterday... or the one that was created in 2021... So.. please tell me what the Browser is called today... Firefox or Mozilla... or Mozilla Firefox... ??? and I'll begin AGAIN... OR CAN YOU FIX THIS FOR ME WITH JUST ONE ACCOUNT, and I'll create another Password. My email has NOT CHANGED for either account... ey47ey@yahoo.com Please advise me how to establish my Account ASAP so I can continue my work. I HOPE I can thank you in advance for clearing this up for me. I'm trying to "Run-Away" from Everything... Google!

Hi, I have been having this issue for a while. The search suggestions in the address bar are missing. I mean that the entire drop-down box never shows up. There are no search engine suggestions. There are no history based or bookmarks based suggestions.

The search suggestions is ticked in the settings. And I also disabled hardware acceleration.

Steps I took to troubleshoot: 1. Refreshed Firefox through troubleshoot mode. 2. Restarted firefox in add-ons disabled mode. 3. Tried creating new profile. 4. Tried using Firefox nightly and Dev builds. 5. Got fed up. Switched to Floorp. 6. I also tried a bunch of about:config modifications, that were suggested in earlier such support posts. None to any avail. 7. Tried it on an entirely different windows. And again, the minute I log in, the search suggestions are gone.

This is when I realized, the issue was popping up whenever I log in using my mozilla account. I tried any firefox alternative without logging in and the search suggestions work. The minute I log in with firefox account/mozilla account. The search suggestions stop. This has to be something due to sync is what I guessed. And I stopped sync. And reinstalled. Then the issue resolved. But the minute I log in it reverts back. And no search suggestions.

The search suggestions do not work on any windows based system. I checked my android device and suggestions are working. Sadly, I do not have access to any other platform.

So at this point I was very much frustrated. So someone please help me out. I will give whatever logs you need. But fix this. I need search suggestions. At least bookmarks and history. I believe it to be a core part of the experience.

Not even recently searched are in suggestions. That drop-down box itself is missing.

The address wasn’t understood Firefox doesn’t know how to open this address, because one of the following protocols (javascript) isn’t associated with any program or is not allowed in this context. You might need to install other software to open this address.

Im getting this message on my newspaper site. It will not let me open the whole page just one article at a time but only after clicking above message

Hi,

I am trying to print a long webpage into a PDF format. When I open the Print preview window, I noticed that pages after the 255th page are all blank. I tried changing the destination but this seems to be a persistent issue. I tried the same procedure with Microsoft Edge and the entire page was able to be seen in the Print preview window.

Thanks

Using the Firefox with Google search engine, and below it has several icons for direct links to urls.

How do these links get there ? How do I delete one and replace with another link ?

Thankyou

Charles

This problem began a couple days ago. I have no problem accessing other sites on Firefox (and none for this site over years of use.) Can access site on Safari without problem.

I can no longer use my camera on firefox, firefox displayed some message about camera when we were trying to chat, but I missed it, I have granted relevant permissions on the site, that we use reularly. The camera icon on the address bar appears red, and I noticed that in Windows security, it lists firefox access requests, but shows no way to grant these requests.

I am not tech minded so please if anyone could keep it simple, I would appreciate it.

Out of nowhere a couple days ago Firefox started loading local html files extremely slowly. I was using Live Server to render the pages, so I turned that on and off, uninstalled and reinstalled to no avail. I tried dragging files in from the original folder on my computer, but even that doesn't work. I tried updating firefox, and then my computer (which is running Fedora Linux 40), but still nothing.

When I try hitting inspect on the page, it only loads the HTML but doesn't let me inspect the JS as it wont load, and it's saying I have a ton of errors too. I can't look at the errors because they wont load, but I know it doesn't have to do with the original file as there was only one error which the page was working fine with before and each time I try opening the file it gives me a different amount of errors.

I tried clearing my cache and cookies, which didn't work either.

Does anyone know how to fix this? I'm having no other errors on other pages.
