Diễn đàn hỗ trợ Firefox

Acting on advice provided by the Computer Active magazine I have installed uBlock Origin in order to block adverts. I was advised to stop using Adblock Plus. Adblock plus had an icon which I could click to see if it was working. uBlock Origin doesn't seem to have any visible icon. The add ons manager indicates that uBlock Origin is the only enabled extension, but is it doing any advert blocking? Shouldn't there be a clickable icon?

Firefox unexpectedly closed on me and when I opened it up again it did not immediately give me the option to restore closed tabs. So I went to the menu to click on restore closed tabs there but the option was not provided to click on. How do I restore tabs under this scenario? Thanks.

Firefox 116.0.2 64bit on Windows 11 Pro 22621.2134

I noticed today that a video hosted on the website Reddit has subtitles on it. When I view the video in other browsers it does not have subtitles. Why are subtitles being generated in Firefox for this video? Is there a way I can disable these subtitles? While often useful, the subtitles in this case just get in the way.

If URLs are allowed one example is here: https://v.redd.it/z7tekckuy9hb1

Thanks.

Firefox for linux ubuntu is what I'm using on my laptop. I installed browsec VPN and it does not launch. I've used this before linux mint and I did not have any problems.

Last October my sessions were gone after a Firefox Update. I asked for help here: https://support.mozilla.org/sv/questions/1394685 and eventually got kind help from @cor-el (that unfortunately wasn't skilled enough to understand) and from @RayGibson57. But by then, my life was in a flurry and I didn't have time to try the advice. And so, after a while I had, with some effort, gathered many of the old tabs back again, and built up new sessions.

This Monday I was trying to internet while having high fever (something people should never do :o ). I left three blank windows open when I shut down the computer, and next morning those three were the only ones Firefox wanted to remember.

(I still find this change frustrating, bordering on infuriating: what happened to "Choose how many old sessions you want Firefox to remember", I think the maximum was ten?)

Now the fevers left and I went to those answers to try. That Q/A was archived though, so I'm starting again here, from as far as I got following King Rays instructions. They were:

1. Open the application menu (3 horizontal lines) next to the address bar.
2. Click on Help -> More troubleshooting information.
3. With that page open, find Profile Folder and click on Open Folder. That's how you get to the folder with backup files in it.
4. Set computer up to see all the extensions & system files. By default, the extensions don't show up (.jsonlz4 is an extension).
5. I found an older file in that sessionstore-backups folder and copied it one level back to the main profile folder.
6. Renamed the sessionstore.jsonlz4 to sessionstore.jsonlz4.old and the file I copied, I renamed to sessionstore.jsonlz4.
7. Opened Firefox and that missing window was in the history so I could open it.
8. Don't make any typos here, because Firefox won't find the files it needs to open.

I got as far as finding the Profile folder and the sessionstore-backups folder.

But I cant find any jsonlz4 file called "sessionstore". Only a "sessionsCheckpoints" and that one is a json file, and the date modified is today.

See screenshots please!

Can anyone talk me trough this like Im a grandmother from Sweden with extremely limited coding & tech skills (which is what I am)?

Until recently, this extension had worked well on YouTube, where downloading videos has usually worked for years without an issue.

However over the past month or so, when using the Linux system, it's become impossible to download any video from YouTube, without an error popping up after a couple of seconds.This occurs whatever choice of aspect for a video is available, be it in mp4 or mkv format. I should emphasize that this issue only seems to occur on YouTube. Other unrelated sites that host video-sharing still work with Linux.

In Windows 10, Video DownloadHelper with YouTube still seems to be working as normal. So any ideas why I can no longer use this extension with Linux and YouTube?

This just started happening today When I try to sign in to my comcast email account from my desktop shortcut I get Peer's Certification has been revoked Error Code sec_error_revoked_certificate if I go to my bookmarks I can sign on????? My wife has a seperate sign in on windows 10 and the same thing is now happening to her, never happened before today

I have added a two factor authorization and when I sign it it asks me to check my app and enter code. I have no clue as how to do this. I have googled it and it says download google authenticator app and that doesn't work so how in the world do I get the code to enter it . I had to disable two factor because your systems makes no sense, usually you send the code to a phone number not an app that doesn't exist.

I used to have LIBRARY and ORGANIZE in the drop-down menu of Bookmarks...They disappeared after having to RESET Firefox a while back. I have tried searching everywhere, settings, etc.

Every time I log in to Comcast.net, which is my home page, I get the following message:

"Secure Connection Failed

An error occurred during a connection to idm.xfinity.com. Peer’s Certificate has been revoked.

Error code: SEC_ERROR_REVOKED_CERTIFICATE

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

This started happening just a few days ago after your recent upgrade. If I get a new window, I can then log in to Comcast. Why am I getting this message now. It's only started recently and I've been using Firefox for years.

Whenever I use amazon prime to stream video after watching for several seconds the video quality is throttled, this also happens to youtube videos but mainly effects FPS and only when im tabbed out and using my second monitor. I am 100% sure this is not my computer or wifi as both are very good and the problem does not persist when I swap browsers.

I received an email and my practice is not to open links in emails. The link was from Bed Bath and Beyond. I searched for Bed Bath and Beyond and got this URL https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwi1xvXC-NSAAxXykloFHUgzAJIYABAAGgJ2dQ&gclid=Cj0KCQjwuNemBhCBARIsADp74QQznb8iH59pv0wRyjGRO4F2u3BCLCFN5wLnICvobs8wZizFvugIjzkaAjGVEALw_wcB&ohost=www.google.com&cid=CAESauD2_nc6dMVeEHYVGwflfbexMnAE3HOMV2sVmt1JRptWGi8nNcESdzKw4HPrcf9Q8fDAHENpm6rtMoAupgWXY3qw8KD7WPccsNuuSzG41vCoKK7d4j8eeU0Hou9aU-BSp1czBDDnEMhGAvE&sig=AOD64_2tVufyv3ivTfWScwK-WyCpRmIW3g&q&adurl&ved=2ahUKEwiY5e7C-NSAAxXORjABHX0YChwQ0Qx6BAgNEAE

FireFox would not open the link but Microsoft Edge did. Is there a potential security problem that I am not aware of or a problem with FireFox?

I use Windows 10 on an HP desktop computer and want to get rid of BING entirely. I'm not a computer whiz, so I need step-by-step instructions.

Please help!

I have always had this option with Chrome and other browsers. But I can't find this feature in the latest version of FF.

I want to disable images on specific websites, not all websites. I examined my address bar and there's no option there at all when I'm the specific site I want to block images and/or media.

I am running Firefox 116.0.2 on a Apple M2 Pro Mac 2023.

Apparently there is some support of passkeys but it doesn't seem to work.

Steps: 1. Visit https://www.passkeys.io/ 2. Do the demo, filling in the fields, until you reach the "Save a passkey" prompt. 3. Click "Save a passkey".

You will see "Touch your security key to continue with www.passkeys.io". I touch the Touch ID sensor, nothing happens. Kinda confused. Am I doing it right? Does Firefox even support passkeys.

What shall I do? I would love to use this feature but I am not sure how it is supposed to work

I recently replaced my mouse on my PC. Now, when ever I click Firefox, MSN comes up. I have tried to delete MSN but it does not show up on any program. Please advise about removal of MSN so that I can continue to use your website which I have enjoyed for many years.
