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!

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.)

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

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

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 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.

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?

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.

I used to have no problem opening messages.google.com/web/conversations to link my messages to my Pixel phone. Just recently the site will not open in Firefox. Not an error message, it just won't open the page.

My "recovery.jsonlz4" file from a previous install will not reopen my previous session (tabs) after the new installation.

Before deleting my previous installation of Firefox (for a clean install), I did two things: I created a restore point, and I did a backup of my old data.

The data consists of: bookmarks-2024-05-10.json

These folders: C:\Users\[machinename]\AppData\Local C:\Users\[machinename]\AppData\Roaming C:\Computer Files\Mozilla Firefox\distribution C:\Program Data\Mozilla-1de4eexxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Within "Roaming" I have Firefox\Profiles\xxxxxxxx.default-release\sessionstore-backups

In that sessionstore-backup, I have a "recovery.baklz4" (most recent session, I'm guessing) and three others that look like "upgrade.jsonlz4-2024xxxxxxxxxxx

With Firefox closed, I took a copy of "recovery.baklz4" (745 KB) and pasted it into the current sessionstore-backups file, then I changed the file to "recovery.jsonlz4".

I thought that when I reopened Firefox, my previous tabs would appear. They didn't. So, I went to the menu, then to History, and clicked on Recover Previous Session. That didn't do anything either. And it reduced the size of the *.jsonlz4 file from 745 KB to 6 KB.

I'm not sure what I've done wrong. Can you help me out?

Thank you.

if i search in the firefox bar then google always search "all time" but i want it to search the last 3 year. i have a code for that this: https://www.google.com/search?q=%25s&sca_esv=cd9a55a255ee4ca7&source=lnt&tbs=cdr%3A1%2Ccd_min%3A2022%2Ccd_max%3A&tbm=

but how can i change this in firefox? where i need to put this or how?

I had issue with notifications (showed up but when i click on them they didnt were redirecting to original tweet) so i cleaned cookies after cleaning cookies i doesnt have option to turn on push notifications.

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.
