i just upgraded firefox for Mac OS to 115.23.0esr (64-bit) and now I cannot log in to my bank account from this desktop. Safari works on the iPhone but I NEED FIREFOX ON THE DESKTOP IMAC (Sierra 10.12.6) There seems to be NO INFORMATION ON YOUR "ASK A QUESTION" PAGE ABOUT THE UPDATE

I have an Arch Linux installation with Plasma desktop. Software is always kept up-to-date. Sometime recently, Mozilla apps, Firefox nor Thunderbird, will no longer print, neither to pdf nor to network printer. These always worked before. Now, if even "print preview" is invoked, the dialog opens as a blank sub window with only the word "Print" in upper right, and at left center is "Preparing Preview with rotating time delay wheel, which never resolves. All other apps, including other browsers and mail handlers, will print without issue. I've tried the obvious checks with no success. Where could be the problem? Is there a helper app shared by Firefox and Thunderbird that could be the issue? The only potential remedy I have not yet tried is complete removal of both Firefox and Thunderbird, as that would cause re-configuration issues for both. It's necessary to press <ESC> to terminate the print window when it fails to respond. Screenshot attached...

Respected Sir/Madam, I found a problem to use Mozilla Firefox (137.0.2 (64-bit)) on Windows 10, problem shows in attachment.

Already uninstall Firefox and reinstall it but problem not solved. After restart PC Firefox works and it browsing speed is very very slow but after close Firefox problem start again.

Please give me the solution. I am a die hard lover of Mozilla Firefox.

Hello, everyone,

I don't seem able to install Firefox on a Windows tablet (at least I think it's a tablet, it's an Asus Transformer Book, with a tablet screen and a detachable keyboard, anyway). Does anyone have any ideas why, please?

I should warn anyone before they read on that I am in no way techie, so helping me may be frustrating at times as I need advice/instructions etc spelled out really simply, as anything too technical is beyond me, I'm afraid.

So, anyone brave and/or patient enough to read on... I've bought the tablet secondhand, 'wiped' etc. It's an Asus T100HAN Processor: Intel(R) Atom(TM) x5-Z8500 CPU@ 1.44GHz 1.44GHz Installed memory: 2.00GB System type: 64-bit Operating System, 64-based processor Pen and touch: Full Windows Touch Support with 10 Touch Points

It's currently running Windows 10 Home, but I'm hoping to install Linux Mint on it, although it's only since I bought it that it's occurred to me that putting Linux on it might not be as straightforward as I thought, (ie I'm typing this on a laptop that came with Windows but on which I installed Linux Mint. "If Linux runs on this, it must run on anything that can handle Windows," I thought to myself before buying the tablet. But now I've realised that, eg, this laptop doesn't have a touchscreen, not does the screen have to rotate, which is the main reason for buying the tablet.)

That's sort of a digression, but might not be, as it explains why my priority right now is installing Firefox on the machine - so that even if it turns out I can't install Linux on it, at least I'll have Firefox rather than Edge or whatever.

So, in the Edge that came already on the machine, I accessed the official Mozilla page (despite getting several scary warnings from Edge about there being a problem with "this website's" security certificate, oh, and something about "Windows SmartScreen can't be reached at the moment") and downloaded Firefox. I went for the desktop version because that seemed more relevant than the Android or iOS versions. Then I've told it to "Run". The installer thing has come up and the little colour wave thing has happened with the icon in the taskbar (or whatever it's called). And then, after several minutes, I've got a message from Firefox Installer: "Hmm. For some reason, we could not install Firefox. Choose OK to start again." So I've clicked on OK, and the same thing has happened. Several times. And I've downloaded Firefox umpteen times as well, just in case there'd been an issue with that first download, only the same thing has happened, over and over again.

From the "about" thing, it looks like the 30GB or so of storage on the tablet, but about 10GB(!!!) is taken up by "system files to help Windows run properly. Your PC won't work without them."

Can anyone explain, please, what's going on, and what (if anything) I can do to get the wretched thing to allow me to install Firefox? I could just about cope if I can't get Linux, but no Firefox??? No, no no!

Thanks, Alice.

Hi everyone,

I’ve recently started playing Krunker.io (a browser-based FPS game), but I’m facing a lot of lag and stuttering in Firefox. The game runs fine for a few minutes and then randomly starts slowing down — especially during fast action scenes.

I’ve tried the basic stuff like:

Updating Firefox

Using private window mode

Closing other tabs

Enabling hardware acceleration

But the issue still comes back, especially when I play for more than 10–15 minutes. Has anyone else experienced this with browser games on Firefox? Any tweaks or settings you recommend to improve performance?

Thanks in advance! 😊

As the title suggests, I've found that exceptions added for 'Enhanced Tracking Protection' simply do not function in a private window; they're entirely ignored. The discovered 'Tracking Content' (from shield in the address bar) will list the exact domain that's whitelisted and the network tab of the devtools will label the URL as blocked due to tracking content. Obviously this is wrong, that short of per-window type settings, this should be global (and makes no sense to differentiate anyhow).

Switching to a standard window fixes this, however, and the exceptions are taken into account.

Greetings...

I am a frequent user of multiple tabs whenever I use Firefox. As a result, the new Tab Groups feature interests me, primarily if it will help my to organize and manage my multiple open tabs. Initially, I have the following specific questions.

Q: Is there a maximum quantity of tabs that a Tab Group can contain?

Q: Is there a maximum quantity of Tab Groups that can be open at the same time?

Q: Does the use of one or more Tab Group negatively affect the performance of my web browser?

Q: Can a Tab Group be bookmarked? (Periodically, I need to bookmark a group of open tabs and I am currently able to do so by selecting all of the tabs then bookmarking them as a set.)

Q: Does the new Tab Groups feature represent a way to reduce the number of open tabs that appear at the top of my web browser - basically, a way for multiple open tabs to occupy a smaller space versus scrolling them across the top of my web browser?

Thank you very much for your feedback! Take care...

Dear Firefox Team,

I hope this message finds you well. I would like to suggest a small but useful enhancement to the Firefox interface that I believe would improve user experience and accessibility.

Currently, in the "Customize Sidebar" section, the available tools are limited to a few items such as AI Chat, Tabs from Other Devices, History, and Bookmarks. I believe it would be very helpful to include "Downloads" as an additional sidebar tool.

This would allow users to quickly access their recent downloads without needing to go through the menu or use shortcuts. It adds convenience and aligns well with the purpose of the sidebar — offering quick access to frequently used features.

Thank you for your time and for continuously improving Firefox. I look forward to seeing future updates! Warm regards, Julabeeb a firefox user, developer, and contributor

i write an email and it automatically goes to the outbox,.... but it never is sent. my sense is that it's trying to send emails via another browser... not firefox and it just locks it up.

Youtube is nonfunctional on firefox as of April 29 2025. It was all working fine last night, then I woke up to no youtube. It loads the website as a blank screen. Videos can be accessed by going directly to their URL, but no recommendeds load in, no comments section, even the title and channel information is unavailable. I would say none of the buttons work, but there are no buttons to test. It works fine in Chrome still. I know it's not my extensions because I tried removing them all, and it didn't fix it. I know it's not my cache/cookies, because I cleared that too and it didn't fix it. I know it's not on Youtube's end, because it works fine in Chrome. I know it's not an update issue, because I updated my browser and it didn't fix it. Please. I want to be able to use youtube in firefox. Please help me fix this thing. I have attached photos, but I suspect they'll be more demonstrative of the problem than useful for troubleshooting.

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

Firefox is not loading on my desktop full sceen. I can see a small page minimalized when I put my curser on the Firefox icon. This has happened once before and I had to uninstall and install and I lost a lot of settings doing that. Please advise. Picture on the left is what I see, not the other.
