Firefox Support Forum

I had about 100 tabs open but when I opened up my bowser they had disappeared from the 'Recently Closed Tabs' list and the vast majority don't appear in my History.

How do I recover the Tabs?

TIA

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)?

Two, maybe three updates ago, not sure how many since there seem to have been quite a few the past couple of months, the PDF option in the Print Friendly & PDF extension stopped working. Period. It's still usable for deleting content on a page but when the button to send it to Adobe as a PDF is clicked, a graphic with a large down arrow is shown with a scroll bar that at the end says Download Your PDF. Clicking that brings up a box that says: The page you were looking for doesn't exist.

You may have mistyped the address or the page may have moved.

If you are the application owner check the logs for more information

I've removed and reloaded Print Friendly a couple of times in case that was the source of the trouble. No change.

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.

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.

Recently when I open Gmail it opens and everything is on the left side of screen. There are no graphics just letters on left side. How can I restore back to normal web browser page? If I use another browser Gmail looks normal.

I am running the latest version 116.0.2 (64-bit) on Windows 11, but this same issue occurs on my Windows 10 machine.

I have been using Firefox for a few years now.

When I watch a video that has a popout screen and then close the video, it crashes Firefox. This has occurred since I began using Firefox.

when i am opening any streaming site and play the video, the audio stream of the video sometimes start late and some time does not even start when the audio is played via bluetooth audio device.

I have realized I am flooded by alien bookmarks coming into the browser. I have never used any sync options and I made my account within the browser on this very day. I am not using firefox on any other devices and I am 100% sure these are not my bookmarks, they have 0 visits and they appear to be added at one moment. It appears that someone else's bookmarks had been loaded into my collection. I don't know where to look for the source and the Sync option only shows one connected device.

Trying to browse to a website that I know is safe, but it's an old site and it looks like the security certificate is expired. I'm getting:

"Firefox detected an issue and did not continue to jeconais.fanficauthors.net. The website is either misconfigured or your computer clock is set to the wrong time.

It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely.

What can you do about it?

jeconais.fanficauthors.net has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem."

I cannot find a way to bypass this or turn this off. Why is there no option to do this (when there has been in previous versions)?

Google sponsored links (those on top of a Google search for a product) not working in Firefox, works in Chrome and Edge. The example link below uses googleadservices.com, which appears to be the problem. When trying to load that link, Firefox does nothing. The same link plugged into either Chrome or Edge works fine. This is a REAL PITA!

Thanks, Bill

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.

Hello,

I reinstall my windows 11 yesterday and since I cannot log in office. I go through the identification process, then once done I am back to the sign in page.

On chatGPT, when I go to login, I got the error message "We ran into an issue while signing you in, please take a break and try again soon."

Both websites were working fine last week. Also on the same computer I can access these websites using chrome. I tried to clear the cache and the cookies, disable extensions (ublock + cuberghotVPN), lowering security options like disable DNS security and disable tracking security, I uninstalled and reinstalled firefox, but I can't fix this issue.

I am a bit out of ideas to try. Anything else I can do to get access back to these websites?

Thanks

When I am typing in a search request in google, the type disappears frequently and I cannot even correct it because the whole line disappears. I thought this was happening when I misspelled a word but it seems to happen in other situations also. This is very annoying.
