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.

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?

I used Firefox Developer Edition and yesterday saw that a new extension released for using Chrome web api to search and duckduckgo as one and had to test it "DuckDuck Chrome"... I have since had keneral level drivers registered, IP addres ls directly connecting, every one of my files scanned and index and still I'm getting logs for connections from the same IP's that were using kernal calls to bypass me seeing whats going on... at one point they did a lernal call and changed the requested package power.

There were enough things ran from 5am pst today till 4pm pst today I have exporting the log file for multiple hours and it only has a tray icon telling me it's still creating it as the context was to large to be seen or queried in the Event Viewer itself (error 1734).

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.

Unable to run firefox. I get the error message. (see attached screenshot) After terminating firefox processes, I attempted to create a new profile. and see an error message. (see attached screenshot)

Good afternoon,

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

I have scoured the web and read/tried everything. I cannot remove the time and date stamp from my documents. No matter what program/app they are printed from it shows up ruining my printing. I've tried unchecking the header/footer box. There's nothing in my brother printer set up regarding the date/time stamp. It has to be firefox. How do I fix this? I'm not a computer guru so I need details. I'm at my whits end! Thanks!

Suddenly on my PC the icon of Firefox turned white on both desktop and taskbar. And whenever I try to open Firefox, it says, "The file or directory is corrupted and unreadable." And I didn't make any changes myself. So far it was fine. Now what can/should I do?

Hello All,

Since my Firefox browser has many issues these days, I tried to reinstall it but forgot to leave the box next to “Remove My Firefox Personal Data and Customization” unchecked when I proceeded with the installation.

I don't have any manual backup of my Window 11 system or bookmarks / passwords stored on Firefox. And all Firefox folders now have a last-modified time later than the time when I clicked the installation file. Thus, I guess my bookmarks / passwords stored over the past two years are forever gone. But I would like to make sure that it is really the case so that I can move on and start feeling better.

I understand it was completely my careless mistake. But your kind feedback would really, really be appreciated.

Thanks!

Something in Mozilla's latest update to version 125.0.3 caused a problem with Hotmail only displaying a message, but when I click on the message, I can only see the title, NOT the body of the message. I have NO issues with a Windows computer. What can I do so I can see the body of the message?

When will the new version of Firefox fixing the PDF reader vulnerability be rolled out?

Unless there is some patch one needs to re-install a non-vulnerable version.

Hi - I can't get 'pocket recommends' stories to appear in FF on my macbookpro (14.4.1)

I have both speakers and a headset on my desktop. The system has worked fine for the past 1.5 years. Suddenly today, when I unplug by headset and select speakers for audio, it works for other apps, but not on Firefox browser. Can someone offer some possible reasons for that and, even better, as solution?
