My computer, being 7 years old (and without the space to upgrade to WIN11), has always been a bit slow with low RAM and storage. The swap from Chrome to Firefox essentially gave it a second life, as Firefox didn't need a lot of space to run. Recently, though, it locks up with almost every search, refusing to let me x out a tab and try to save myself for 3 minutes or more, and the bluescreens have come back, too. If chrome hasn't also gotten worse, I'm considering switching back. Does anyone know what happened? I haven't installed anything new.

It's really frustrating and disappointing, because I thought I had a solution when I swapped to Firefox.

Hello! I have a question regarding Thunderbird version 144.0.1.

The server is configured locally and isolated from the Internet. There is an issue: when the network cable is unplugged (no network connection), saving received emails with attachments (for example, total file size of 14 MB) to the hard drive happens quickly — about 5 seconds. However, as soon as the PC is connected to the local network, the saving process for such attachments slows down significantly — up to 60 seconds.

I would appreciate your help with analyzing this issue and possible solutions. What could be the cause of this behavior?

Thank you!

On a new tab in Firefox Focus for iOS 26, the floating keypad first appears, and once Dragged to bottom to make the full keypad, it glitches, erases what I wrote, and brings up floating keypad again. I know this is a beta and has bugs, this is just FYSA for iOS 26

When I go to some websites, such as Corair.com it hangs. I cannot click on anything. If I try to access specific pages via a search engine the same happens. I can close the browser but the 8+ processes don't terminate so I have to kill them from task manager.

I clear all of my browser history when I close FF so I can't remember all of the sites this happens on, but it was more than just Corsair.com.

I'm using 140.2.0esr, but also had the problem with 140.1.0esr. I did not have this issue on 128.12.0esr (I upgrade to 140 after that).

I tried turning use hardware acceleration off/on, that didn't fix it.

I am just about to try safe mode.

Thunderbird very slow to respond when opening the program. On opening any email it freezes for a couple of seconds resulting in a "Wait for the program to respond" or "close program message" . This also happens when performing any action in Thunderbird. This has been happening for the past two or three weeks. Can you tell me how to fix this or is it something you need to do to fix.

Firefox is using about 15-20% of my CPU, with only one tab open. Running Firefox 141.0.3 (64-bit). I changed performance settings as suggested in support page; made no apparent difference. Ran Malwarebytes and McAfee scans; nothing detected. I have used Firefox for nearly 20 years, but if I cannot resolve this then I will drop Firefox and switch to another browser.

Been having issues for quite a while with messages, containing images, loading very slowly. After downloading messages (64-bit 115.9.0 Windows), I click on a message that contains multiple images. All the text shows immediately, but in place of the message, all I see is a highlighted link to 'image'. After 15-20 seconds, each actual image will start loading. Any ideas what is happening here? Thanks

For the past two weeks or so the subject and correspondent columns of Thunderbird email have appeared blank; although double-clicking in the columns opens lines of code. How do I correct this? I have uninstalled and re-installed Thunderbird without effect.

Understand that TB does not have an upper limit to size of inboxes. I run a email-driven micro business and my imap inboxes grow in size very very rapidly. I have a super large storage with my email provider so storage is not an issue. I wonder if imap sub-folders can have less issues compared to a single imap inbox. Any advice will be appreciated.

I am running Firefox on Windows 10 64-bit, and I have lots of windows and tabs open. Occasionally I will get a message from Windows that I am running low on disk space. Recently I got the message, and I saw on my C-drive" "336,044,032 bytes free". After I did an Exit in Firefox, I saw "10,082,402,304 bytes free". The space that was freed was in the pagefile.sys file. Is this normal?

Hi, Please help with my issue: There are 2 Firefox browsers running on my Windows 10 desktop. How can I find one to delete it. My CPU is running very high in Task Manager. Thanks, I just can't find it and I desperately need to do so before my computer crashes! Many thanks any help you can offer is very much appreciated :)

When I sign in, multiple firefox open, causing my machine to run slow. I have to go to task manager, close all the firefox and start over. I usually have to do this several times before I can get signed on. Once on, the new Windows 11 seems to work well with Firefox.

I noted in the multiple firefox accounts the following Group or User Names in the Details section. Are these normal or could they be the source of my problems???

How to correct if a problem.

Some websites won't load at all while other are very slow to load but some will load just fine, example Crunchyroll (screenshot attached) won't load at all its just spinning loading icon and a white page but if I try it in a different browser it works just fine, but with Youtube it will load but is choppy and low quality videos and same thing as before I load it in a different browser and no problems. I have tried every possible solution I can find from clearing cookies and cache to refreshing Firefox even scanned for malware and virus nothing has worked please help me figure out what is happening and why it's only with Firefox that I am having this problem and its not hardware can play online just fine and download games from steam perfectly fine.

Hello everyone,

I have checked a lot of other questions already but I can't seem to find a solution to my problem.

I have Firefox installed on an old Laptop with macos Catalina. Reinstalled it many times with and without extensions, without any data but it doesn't matter what I do, even on a blank slate of a new reinstall of Firefox it just takes way too long to load or doesn't load at all and then even hangs up so that I always have to force quit it and slows down the entire laptop. It also sometimes loads tabs only if I reopen them or have to go to an already open tap that has been working to be able to open it.

I have been feeling super frustrated for days because I can not figure it out.

Thank you all for taking the time!

For the past few weeks, my PC reliably crashed after a few chess games on chess.com with Firefox. GPU and Memory benchmarks are running through without issues, it did crash when starting a Steam game once before, but I wasn't able to find out why. At this point, I'm really curious to learn about what could possibly cause this, but don't really know where to look for it. Really wondering what special thing is happening after a game there that doesn't happen with other websites/browsers. Would really appreciate your help!

Running Wayland on Archlinux 6.15.7 with AM5 CPU and DDR5 memory. Sometimes wondering if it's a graphics issue since my display is connected via the iGPU, but I also have an NVIDIA graphics card installed that I use for games sometimes.
