Firefox Support Forum

Hi, Today I discovered that firefox has logged me out of every site. I checked the cookies and there were cookies.sqlite and cookies.sqlite.bak. When I delete the newly created cookies.sqlite and rename cookies.sqlite.bak to cookies.sqlite, I am logged back in to all sites and everything works fine. I notice that the cookies.sqlite.bak file is created when I go to twitch.tv. Can I check what is causing this problem and fix it somehow? I've already tried deleting the cookies just from the twitch.tv site, but that doesn't help.

OPEN PREVIOUS WINDOWS AND TABS is unchecked but upon startup firefox always tries to do this and I get an error message. Computer crashes, shutoffs, sleep mode and Firefox wants to go to my previous windows and tabs : I HAVE IT UNCHECKED FOR A REASON, I DON'T WANT TO GO TO PREVIOUS TABS.

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 can add the short cuts I want but if I go someplace new Firefox will add it to my shortcuts without permission. This seems to be a new problem, and I don't like it! Then if I dismiss or delete from history its still not removed! Very annoying and may cause me to ditch Firefox for good!

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.)

Hi, I'm using Firefox 125.0.3 64-bit with Linux mint and some of the tiles on the homepage have disappeared I have selected 4 rows in settings but only 2 and a half rows show, I can remove all rows and select 4 rows again but only 2 and a half rows will show all the edit, pin etc, options are there and work and I can rearrange the tiles but if I dismiss a tile it disappears completely, any help much appreciated. please see added image.

This isn't the first time this has happened. After each occurrence, I have to completely uninstall the browser and reinstall it from scratch. This means I have to reopen all my tabs, which is very annoying. In Chrome, I have had a large number of tabs open for many years and it works fine.

With Mozilla, something terrible is happening... I have many tabs open in Mozilla, and there comes a moment when, upon launching the browser and opening two or three tabs, Mozilla starts consuming up to 10 gigabytes of RAM. If I open a few more tabs, the browser crashes. I don't need to open 50 or 100 tabs, just 7-8-10 tabs are enough to make the browser crash. Moreover, if I open a new tab and go to google.com, the browser takes a very long time to load, even if it's the second tab.

This problem has happened before. I don't do anything with the browser, just visit sites like YouTube.

Clearing the cache and other recommended actions do not yield positive results. This is very annoying. Mozilla is my first and favorite browser, which I have been using for almost 20 years. I wouldn't want to uninstall Mozilla.

A few days ago I started having an issue where Youtube videos 1440p and up would frequently skip ahead, stutter or freeze and play audio only. They also stopped loading as quickly as they had before. This issue only happens in Firefox as when I watch Youtube on Chrome everything is fine. I've tried disabling extensions to no effect. Is this a known issue or does anyone have suggestions?

Hi Lots of my files on Mac have converted to Firefox (which I don't use) and will not open either in Mac, Adobe or Firefox. They are showing in my icloud drive but I cannot open them. And I REALLY need them as they are the source files for a website. I have no idea why this has happened, but would love some advice on how to fix it. I don't ever intend to use Firefox so not quite sure how it happened. Many thanks

I've always had my firefox checkmark the "Always ask you where to save files" box. I started to download a file from Envato elements, and firefox asked me where I wanted to put it, so I pointed it to a dropbox folder on my finder level (I'm on a Mac computer). Some pop up showed up that said it didnt like the directory so I hit ok. Then I tried to download again to another location but now firefox won't ask me where i want to download the file to. And instead it just populates a file in the downloads folder called "7gp69ST8.mp4.part" or something similar. If I uncheck "Always ask you where to save files", the whole file downloads just fine to the downloads folder but I dont want that setting, I want the check mark ON so that it asks me each time where to save the file to. But its not asking me any more. So I hit quit on firefox and came back in and the issue persisted. I cleared the cookies and the issue persisted. Please help me fix this.

you dont need a screenshot. its reral simple i am tired of nothing working right. i have added multiple wallets on my phantom app but it doesnt show up on my phantom wallet on my laptop. i have been hitting check for updates for 2 hours. why wont it update. and if i have to put in a 24 word secret phrase evertime i want to update my extension. then good bye firefox. then why have a check fofr updates button.

in google and in other browsers when you have multiple tabs in a container you have an option to minify all tabs in the container. is there a similar feature for firefox,

thank you!

I was able to open reddit.com without any problems earlier, but recentrly I'm not able to load it up anymore. The loading screen is eternal and it doesnt show any kind of error (unless it tries to connect for too long like a couple of minutes, then the error does shows up). The site still sends me notificarions through the browser though. Any other site loads up without a problem. I tried to use methods mentioned in the help article (turned off proxy, turned on network.dns.disableIPv6, deleted cookies and cache). In other browsers (Edge, for example) reddit.com loads just fine. Please help me if you can.

Hi,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

There seems to be something specific to the Phlearn site and Firefox which prevents videos from auto advancing. They either recommence the just completed video or revert to an earlier one.

I had downloaded a couple of pdfs from google drive via private browsing which were stored in my 'Downloads' folder. But as soon as I closed the window the pdfs were deleted. I had also downloaded a zip file which wasn't deleted.

Hi there!

I'm trying to troubleshoot why firefox isn't connecting to my DNS over HTTPS instance running adguard home. Every other device (including another laptop) is able to set the DNS over HTTPS and connect successfully - but my desktop PC instance gets NS_ERROR_CONNECTION_REFUSED. Despite multiple reboots, ipconfig /flushdns, release/renew, etc...

Even my android phone is able to connect to it using the "private dns" feature (uses port 853 instead of 443).

I've been able to verify https access to the DNS server and it's querying successfully. It's just this one instance it won't connect.
