Firefox Support Forum

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

Hi,

Why is it so much updates all the time with Mozilla Firefox NIGHTLY Browser for the 127.0a1 version that was released 15th of April 2024? I don't even see the benefits of the updates or any information and what the content is in them. by clicking on "What new" doesn't show anything other than this from 15th of April.

We are using a website designed for Firefox, and when we use the "print" function within the website tool bar, on one of our PCs, it always defaults to a print preview which states "Printing from Win32 Application - Print". We have "print.always_print_silent" set to true, on this and all of the other PCs using the website, but only this PC has the issue. We can't figure out what is making it pop up the print preview.

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

Hi,

This has been brought up before, but not with this exact question (not that I could find, at least).

I understand that cookies cannot be synced across devices, but this is not what I am asking for. Is there a way to make firefox sync the list of exceptions? Meaning, only the specified website URL and its status, not the cookies from these sites.

Good afternoon,

If necessary, I am available to add more information about this case (145005), in English or Portuguese.

I am replacing a ten yr. old Dell Desktop with a new HP Laptop. Can you please let me know how to get the new laptop working with my existing Firefox (v125.0.3) with current add-ons, extensions and settings? Thank you for your time !! Rick Perry

I can hear NO AUDIO on ANY webpage, when in Firefox. I have gone through all the suggestions on this page: [https://support.mozilla.org/en-US/kb/what-to-do-if-firefox-wont-play-any-...] but still have the problem.

I have a number of music clips I want to put in one or more playlists to use with VLC Media Player. How do I create such a playlist? (If I'm asking in the wrong place, I apologize.)

I accidentally ticked the "don't allow [site] to show new windows" (I'm browsing in Spanish, forgive me if this isn't how it's written) box and now one of the functions of the site stopped working because it requires the user to confirm their decision via the pop up window. I'd like to know how to revert this. I've given the site special permissions for pop ups and it hasn't worked.

How do I print a document from email, without the sidebar showing? It doesn't show up on the copy but it moves the document way over to the right with only 1/2 of it showing. I'm Electronically Challenged, Electronically Illiterate, please reply in simple English as I'm living proof that you cannot teach an old dog new tricks! Thank you

Hello firefox, I have been using Google Sheets recently. When I use the mouse wheel on Google Sheets, the screen will not scroll bit by bit, but suddenly the scroll will go to the bottom and right.

Sorry, I am a Chinese user. Using GOOGLE translation assistance, the semantics cannot be very precise. You can refer to the screen recording,

Hello, Mozilla Community, Hope you are doing well I'm contacting you to ask for help with a Mozilla Firefox problem I'm having with trying to visit the following website: https://www.chiropracticco.com/ It won't load, and I'm not sure if that's because of a bug in the website, a browser issue, or something else entirely.

Does anyone else have knowledge of this problem or recommendations for a fix? I've attempted removing addons and cleaning the cache in my browser, but the issue still exists.

I would be grateful for any advice or ideas on improving the usability of the website. Thank you in advance for your assistance.

Should I be worried about this?

I have been getting a message that says firefox has something running and cannot shut down. I went into task manager and 'shut down' firefox, but the message keeps on coming. I then thought that I would uninstall it and then reinstall, but it tells me that it cannot uninstall because it is running, -"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window." When I click on ' Close Firefox' nothing happens. when I click on 'Cancel' the message disappears, but will reappear. Then in desperation, I went into program files and deleted the Fifefox folders but it wouldn't reinstall. There is obviously somewhere a file/file which is screwing me up, does anyone know what this it?
