ANNOYING!! I am unable to reach USA TODAY puzzles.

Window turns black with rotating arrow. I do not want to give in to BING, but I am able to work the puzzles when I use it.

I use Win 11 and normally use DUCK DUCK GO search

As of a few days ago (potentially coinciding with the most recent update?) I've had several websites become varying degrees of unresponsive when using Firefox while being connected to a VPN (Nord, in this case).

Some sites will load but then get throttled--i.e. YouTube will load and (usually) populate thumbnails, but clicking on a video will result in the video instantly dropping to its lowest available resolution, playing for a few seconds, and then stalling. Interestingly(?) if I try to watch a live stream, chat will be fully functional but the video will be unable to load. Other sites will load but then very quickly stop responding at all. Others are straight up just not loading period, while many others have no issues at all.

I've cleared my cache, deleted cookies for the affected sites, tried Firefox in a private window, tried Firefox with no extensions, and reinstalled both Nord and Firefox to no avail. All of the affected sites are fully functional so long as I'm not connected to a VPN, and are also fully functional on other browsers, even while connected to a VPN. All other non-browser related applications that require the internet are also unaffected, and my internet speeds in general aren't showing any issues.

I've been unable to find any other chatter about this anywhere, and I unfortunately don't have any other devices available to try and replicate the issues. I would not be surprised if it was one of those wonderful Me Exclusive DNS issues or something, but figured it was worth throwing out there.

After letting Firefox idle for a bit (like 5 seconds) and nothing playing on the screen, when I come back, it causes screen stuttering for my whole desktop. Disabling hardware hardware acceleration doesn't help much.

I have read a number of reports of tab crashing, which I have continually. Running 133.0.3 (64-bit) on Win 11 Home 23H2. Very inconsistent crashes, sometime will open new tabs other times it will crash. I have reinstalled no change. I ran refresh, no change and now when I open Firefox I get a message to restore windows. I can't seem to get that message to go away. Any suggestions, especially about the opening message? I have used FF for years and am almost at the point of switching to Chrome. As an aside, also have problems on some websites processing information/orders when using Firefox. No problem when I switch to Chrome. Thanks in advance......

A few days ago, something happened to the Firefox browser. The speed is simply terrible, sites are loaded for several minutes. Reinstalling does not help. Other browsers work fine.

I have just installed Firefox on a new iMac, running MacOS 15.2. Firefox will not load any of the websites I have tried, whereas Safari and Chrome do. I have cleared the History and also set "No proxy" but loading still fails.

Firefox Nightly (next generation web browser test) has no animation delay when playing sprunki, but there is a bug in the beta and current versions that become delay. (That's why I use other browsers.) There is no delay in other browsers. I hope it will be fixed.

Hello,

This new version of firefox. I am experiencing icons grey out whenever I opened a new tab. Is anyone experiencing this below?

I'm very frustrated with FF. It's running slow. Downloads are slow etc. I've tried everything that FF has recommended up to and including "refresh" with no effect. It's getting to the point I'm considering not using FF. Does anybody have any suggestions?

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi

For the last day I've been having a problem with FF slow to load. I've tried the troubleshoot mode with little change. When it does load I can have problems with certain web sites loading e.g. Youtube, MSNBC, AOL mail etc. It's never consistent. The cache is clean and I've saved all the relevant cookies, I checked my internet provider and they are having no problems and I don't seem to be having any internal hdw issues e.g. ethernet cable connections etc. I reinstalled FF-not a clean install and seemed to help for a time. Do I have any options other than a refresh? I don't seem to be having the same issues with Edge or Chrome. All W11 updates are current. I look forward to anyone's comments.

I tried all common troubleshooting steps: deleting cache reinstalling different settings turning off adblocker/vpn disabled efficiency in task manager and set it permanently to off in FF

I used to have 1000+ tabs in 2016 no issue. I had problem in past with Firefox using 100% CPU which now it is not using only like 50, but memory is getting full 89% i use also large page file on ssd. Problem is even when i restart firefox it is slow with low RAM usage! SO that's not it! Even 5 tabs sometimes it is slow!

It is so damn slow it drives me crazy! I tried also Quantum in past when Firefox has 100% CPU usage bug and it was only tiny bit better but still caused 100% CPU usage!

All other browsers are anti user cannot even stop Autoplay literal terrorist Firefox is only normal browser unfortunately performance compare to 2016 got absolutely abysmal! I had this problem even in-between reinstals of OS so it doesn't seem it is me. I play demanding games no issues on my PC...

I walked away from my laptop for about an hour and when I came back my task bar was gone. What happened to it? and how do I get it back? Below is the spec's of my lap top that I use/have been using/task bar missing

For some weeks I have ad an issue with Firefox using 50%-100% of CPU. Normally it is the Firefox process itself, sometimes it is also "Privileged Cont".

OS is Kubuntu 24.04. Firefox has done this across 2-3 versions.

Things I have tried:

Restarting Firefox No change, I'll even get 100% cpu usage with no tabs open

Refresh Firefox to remove settings and addons No change

Uninstall Snap and try direct Apt package No change

Remove ~/.mozilla to fully remove any residual settings/cache/etc No change

Try with and without hardware acceleration See: https://support.mozilla.org/en-US/questions/1308215 No change!

I would blame my old computer hardware, but Brave runs fine. I am now using Brave, but would dearly like to return to Firefox as I miss containers, and I don't support a chromium dominated web.

When saving images from websites using the save image as feature, Firefox will freeze up and not register any mouse click or anything instead making a ding noise every time is register a mouse click. This will continue for like 30 seconds before it becomes normal then it will repeat this for every image. How can I solve this?

Lately, I’ve noticed Firefox consuming more RAM, especially with multiple tabs open. Is this a common issue in recent updates? What are some tips to optimize Firefox performance on lower-end PCs? Would love to hear your experiences!

Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

I've rebooted, reinstalled, can't get it working.

Power consumption of Firefox is so high that it nearly killed the display of my iMac. My screen started flickering with horizontal lines across the display. When i touched the screen, it was so hot that I could boil water using it. I did not realize that it was Firefox that was killing my PC until I looked at the power consumption (see the attached screenshot). I hope there is a solution to this since I really love Firefox and have been using it for well over a decade.

i noticed that my laptop is getting too hot, when i opened task manger i found that Firefox is using a lot of ressources every time, i have a decent ram of 24GB and i7 7th gen plus an gtx1050, i don't think it's my work flow because i've been always using too much tabs without any problem, i suspect an update issue, what do you think ?
