I don't what or how it happened.

But one night all I can remember was I updated my Firefox in Windows and my account was synced. I use to have all my browser history on my Macbook air. But suddenly the next day I discover that all of my history is gone. I have no idea what caused or how I can recover it again. I tried the internet and nothing helped me with my problem. So now I'm resorting to this and hopefully someone can tell me what to do.

Even with all media tabs closed, GPU process keeps hogging memory. Tried with extensions disabled, but no effect. The main culprit is this GPU process. screenshot attached.

I just wanna know why everything is slowing down and it’s harder for me to load up anything in my browser like I can’t go to certain websites. It said it’s not secure. I don’t know what’s going on. Never had this problem and downloads and everything and passwords and all and extinction problem. I just need help. Thank you.

This is a problem I only started experiencing yesterday, but if I try to upload an image to a website (such as social media), and I double-click a shortcut for a folder, it attempts to upload the shortcut as the selected file, instead of opening the folder.

This is only a problem with firefox, as I tried doing this in another browser and I was able to open it as a folder normally. Any ideas on what could be causing this or how to fix this?

Tabs not opening. Cleared cache and history. Also went to "Trouble Shoot" restore did not work. Uninstalled then reinstalled. Still did not work. Changed Profile. Still not working. Got to this website by typing in website using Safari.

Hello,

Sorry if this is not the right place to report this, this is my first time and im lost between all these 3 different pages "Discussions/Support/Bugzilla".

The latest Firefox (v137.0) update for Windows 11 that I installed today broke something possibly related to DRM-protected content, at least for me. Now whenever I start streaming live sports, the video always plays in the lowest quality (possibly even lower than the lowest option available in the player, for some reason?).

I tried to restart my PC, clear the cookies for that streaming website, disable all my extensions, but same issue. On my other browsers everything works fine as always, so only Firefox got broken after this last update.

I have both of these options turned ON even before the update: - Use recommended performance settings (Hardware acceleration). - Play DRM-controlled content.

Why do I think it's related to DRM? Because I can now record and take a screenshot of the video, unlike before the update where it always turned into a black screen.

Help please!

First, there used to be a columnar format that included a heading. I could sort entries by double clicking the column heading. This was handy for selecting email by date and deleting or moving them. That seems to have disappeared in Versiona 128.9 Oesr. Is there a way to recover that view?

The reason I discovered this is that I'm receiving a message on virtually every attempted Thunderbird operation saying that there is not enough disk space to complete the operation. I cannot tell if this is a Thunderbird message or a Microsoft (Windows 11) message. I've attached a screenshot. I've checked and there should be plenty of disk space; but, of course, there is a lot of spam mail in my T-Bird that I could easily delete. I've tried setting up Message Filters to delete unwanted email but that, too, produces the error message.

Can anyone tell me how to a) get my column headings back in T-bird, and b) fix whatever is causing the message?

Transferring bookmarks & backups for passwords is easy and I'm not worried about that. But the about:config settings that I have customized and accreted over years so that nothing beeps, spins, auto-plays, loops, or throbs a tab, are not so straightforward. I'd like to review what files I can save how to make sure I do not lose these, which are the most important things to me about my Firefox installs--keeping the web safe for quiet, nondistracting searches and reading.

Windows 10 Enterprise, managed by my organization, but with just enough admin privileges to customize my Firefox.

In trying to access (log in)Social Security Administration, I received "Bad Request""your browser sent a request that this server could not understand. Size of a request header exceeds server limit" I was able to log in with Chrome. Can this be corrected by mozzilla?

I have used Firefox for years and I enjoy the variety of articles that are available to read when I first sign on.

But more and more sites request me to "Please Disable your Add Blocker" and will not let me read the article without doing so

That's fine with me but when I look at my "Extensions" list I do not find any Add Blocker on my Firefox

So...How can I disable it ??

after migrating to new windows 11 pc's how do I set Thunderbird so it will show that you have opened an email off the server at your terminal but others viewing same email account will see it as unopened until they open the email at their terminal, I have settings to not "automatically show as read" on all 3 terminals but now all incoming emails stay black highlighted as "unread" for all users sharing this account even after all 3 user terminals have actually opened said email using POP server

cant recover bookmarks says that security software causes this cant find a answer nothing works please help trying to fix this i have mcaffee security in machine a

I think it started to happen with Version 128.9.0esr | Released April 1, 2025. It is very simple to reproduce: 1. Start TB. 2. TB downloads new messages and continues to do it every 1 minute according to the setting. 3. In 10 to 20 minutes, it hangs. I have to force it to close and then restart it to check my email.

I believe it started to happen yesterday.

Is anyone else experiencing this?
