Firefox supportforum

Youtube audio is extremely slow, I reckon at 10%, but the video is fine and can be sped up or down. The problem persists even in troubleshooting mode, after cache clearing, hardware acceleration turned off, enabled DRM and widevine, driver updates, in private mode or not, logged in or not, firefox restarts, computer restarts.

But Youtube plays fine in Chrome and Edge.

I dont think I didnt anything drastically different, or updated win10 or firefox, or messed with anything. It was working fine a day ago.

Is there any way to reset something?

I've not been able to download anything on Firefox for about 3-4 weeks now. Every time I try to it immediately fails with no explanation given. The only type of download that works is "Save Image As..." Even trying to download a picture with a download button instead of right clicking nets an immediate fail. I feel like I've done everything to try and troubleshoot it myself, but nothing seems to be working.

I've restarted my computer, ran Firefox in troubleshoot mode, refreshed and reinstalled it, checked for viruses and malware, tried both nightly and ESR versions, tried running them as admin, logged out of my Firefox profile, cleared my cookies and cache, changed and reset the download folder, ran a repair for Visual C++, and reset my windows security settings. I'm honestly surprised nothing has worked.

The only thing that I know I haven't tried yet it refreshing my entire computer, but that's my very far last resort because I'm able to download files just fine on Microsoft Edge. Only the Firefox applications have given me any problems, so if I were to refresh my computer and have the problem still not be solved somehow I'd be deleting everything to get nowhere.

If anyone has any other ideas to try that be very much appreciated.

Whenever I m visiting to my website I m facing an issue like getting a horizontal black line near the scroll bar, it is coming up when I make my browser window responsive to the resolution of 1920 X 1080 and when the zoom level is decreased to 90%, 80% & 67%.

This issue I m not facing in other browsers like chrome, edge.

Below is the screen shot attached,

I'm getting this Server Not Found page error with the very irritating "Hmm, We're having trouble finding that site" black screen with a doubleclick.net web address. I'm getting it a lot trying to visit totally legit sites and it's pi$$ing me off. It's not happening in Chrome or Edge but I don't like using those for other reasons. Would like to know what's going on with this crap. It used to be only once in a while and a couple of clicks to other links would get me around it but now it's happening a lot and won't let me get to the intended site at all. Very frustrating!

Hey guys,

I saw in the following post that I can modify the zoom values of Firefox to custom values of my choosing (e.g. 75%, 85%):

https://support.mozilla.org/en-US/questions/1201469

I followed the instructions but it did not work for me. Yes, I did save the changes I made, and I completely closed & reopened Firefox, but the changes I made have not been applied for some reason. Please see the attached image.

I would have ask the question in the aforementioned thread but it's been archived so I had to open a new one. Does anyone know why Firefox does not seem to recognize my custom values (.75, .85)? Thanks!

System: Windows 10 22H2 Version: 129.0a1

Firefox system is permanently set to Dark mode, even when the rest of the OS is light mode. While I can manually select light themes (such as the default Light theme), other dual-mode themes such as Alpenglow is permanent stuck in dark. Is there a way to investigate this?

I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

Hello, On several occasions over the past couple of months, maybe after a recent update, Firefox will not process any web page. In fact, if I try to go to another tab that I had been using, it will not refresh those web pages. However, in most cases, if I try to open in a new window, it works (though it did not just a minute ago). This is very annoying because if you have a couple of tabs open to certain locations, you have to copy down the pages so you don't have to remember where you were in your work. I would imagine that it would be difficult to duplicate but here's my info below. I will be glad to answer any questions you may have.

Thanks!

Ron

hopefully a basic question that can be answered

when I used to use edge, I would browse in incognito. sometimes I would accidentally open a link that would open in the normal browser, but I was able to simply exit without closing all my windows, including my incognito tabs

with firefox, when I'm browsing incognito, something similar would happen.

part of the problem is, that my main tabs are multiple windows, and when i choose to close them, it closes the incognito tabs as well

is there a way to prevent that?

Hello, I'm running FF 124.0.2 64 but in Win 10 on a PC. I have the bookmarks right across the top of the page; the sixth from the left at the moment is Seloger's website. If I have a tab open looking at a TV program website and right click on a link to see more details in a new tab, the new tab opens ok, but the TV program website is overwritten by the Seloger's website. If I use the "previous" arrows, it reverts to the TV program site. If I change the order of the bookmarks across the page, the TV program website will be overwritten by the bookmark then in the sixth from left position. This is driving me mad. How can I force FF to stay with the open tab and not change it by itself?

When I go to Settings > Privacy & Security the only "autofill" setting is to import data from another browser. I am signed in, in the US, and my VPN is set to Seattle.

When I see a highlight reference to browser settings: Java Script enabled; otherwise Firefox wont operate properly. How to know Java Script is not enabled (vice-versa). I'm not sure that I have seen a switch Or toggle to know JS is On/Off

session is completely gone. I tried to restore it via various help articles and forum posts but without success.

I see a stg-backups-ff-126.0.1 fodler in my download folder which contains information about tabs that I had open. But I don't know how to use firefox to use that file.

I alos tried to the \sessionstore-backups folder with files named like "previous.jsonlz4" but I do not get the menu option for restoring a session.

from a file named "error-sessionrestore-1718212432477.txt": 1718212432149 SessionStore ERROR The session file is invalid: : TypeError: state.windows[0] is undefined(resource:///modules/sessionstore/SessionStore.sys.mjs:1163:11) JS Stack trace: initSession@SessionStore.sys.mjs:1163:11 onBeforeBrowserWindowShown/<@SessionStore.sys.mjs:2035:35

Hi,

more Details concerning the problem you can see here ! It should be great if you could help us with some diagnostics, for example why the problem only appears with FF on Linux, not with FF on WIN.

STR:

1. Launch Linux FF
2. Visit this page "Potential issue with plugin PITM" (Preview here
3. Because you will need an Account for visiting account please follow "Konto eröffnen" (Create Account) instructions).
4. After my approval for the account please visit again "Potential issue with plugin PITM"
5. Click "1.png" Below heading "Attachments", that should work without problems.
6. Close image view
7. Move Mouse pointer to image below heading "My test with a screenshot" – should become magnifier
8. Now Click that image

  » Expected (and so it does with WIN): Big image opens in new TAB
  » Actual:  New TAB opens, but without image view.

What are your results? FF Linux Problem or something else?

Few days ago I started to have issues with Zoom Meeting recordings playback. When I open the video it clocks but doesn't start playing. I never had this issue before. Zoom support cannot replicate this issue. They say everything works for them.

I cleared cache and history, restarted my computer but that didn't do anything for me - video still clocks. Playback works fine on Chrome. Somehow playback on Firefox stopped working for me. I am using the latest version.

Please help
