I have a HUGE problem with Firefox memory usage. Some open instances of firefox are taking anywhere from 600mb to 2.8gb of memory. Since firefox opens MANY instances even with only ONE active window, this very quickly uses all available memory (4gb) causing a full laptop crash.

More concerning is that CLOSING the worst instance of memory usage STILL leaves the single open page/tab open, so what exactly was the memory eating instance actually doing ???

I have included a screengrab of the many remaining instances of firefox in windows task manager AFTER closing the main culprit.

I have also included a screengrab of all the adblockers I use which I believed would limit unnecessary memory usage, but does not seem to be effective.

Many Thanks

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

My system memory is reading at 57% right now in task manager, that the vast majority of that is being used by Firefox.

Why?

Normally, this would be called a flaw in the program, not the user, as all I have done in regards to settings is "keep tabs previous open when re-opening Firefox" and "Do not automatically update" because Firefox took it upon itself to not re-open my previous tabs on the last update.

Why is this program eating up all of that memory? I have "Firefox (15)" in Task manager under "Apps" and then 13 more instances of Firefox in "Backround Processes"

Wtf?

Whenever i search something on google, firefox desktop (all fine on android) is failing to display the ai(gemini) answer no matter what questions i ask.

Same happens in the "AI Mode" option that is available in google's recent update.

And, I,m logged in.

This started since a week, everything was working fine before that.

Hi!

I've noticed dropped frames in videos for a while now, but only recently tested the issue. Using youtubes stats for nerds, I found that when videos have a small viewport resolution, it starts to drop frames. (I would test with other sites but only know of youtubes stats for nerds system to detect issues like this) For example a viewport resolution of 1250x703 does not drop frames, however by unmaximising the screen and the viewport resolution drops to 681x383, it begins dropping frames.

Using my 2nd monitor which has a smaller actual resolution, the video drops frames unless fullscreened, see recordings below. Test A | Firefox Maximised but video not fullscreen Test B | Firefox Maximised and video fullscreen This issue also occurs with picture-in-picture mode.

Disabling hardware acceleration fixes this issue but for some reason only affects firefox, using MS Edge with "graphics acceleration" enabled does not result in this issue. Is this potentially an issue specifically with how firefox handles hardware acceleration? Also since I require hardware acceleration to be enabled for 3D model work in my browser, is there something I'm missing here that would allow me to keep hardware acceleration on but not have this issue?

Any help is much appreciated, thanks!

I'm using the vertical tabs feature. I also tried enabling the "Expand sidebar on hover" option, which minimizes the side bar, and only expands it when you hover on it.

Issue: I have a lot of open tabs, and I'm usually working with the ones at the bottom of the list. When the bar minimizes the scroll position resets back to the beginning. So, every time I want to select a tab, I have to scroll back down, which makes this feature very hard to use.

Expected behavior: After the vertical bar minimizes, and I hover again, it should keep the scroll position.

I run a Synology DSM server on my local network. The website page to load locally inside my LAN is along the lines of 127.0.0.1:1001.

MacOSX 15.0.1 FireFox(FF) 132.0 (aarch64)

Previously accessing the DSM via the local IP address worked fine with no problems. Now, following one of the last couple of FF updates, I get an "unable to connect" message.

I also have a domain that routes to my local server and I can still access the DSM via the internet http address through FF. So I know that DSM is running fine and I have verified the settings within DSM.

I can load the DSM via the local IP in both Safari and Chrome. Only FF says it's unable to connect. So that shows that my DSM settings are fine and the page is available and loads in Safari and Chrome via the local IP.

I searched the forum and found similar postings, but not quite the same issue as mine. I deleted the cache & cookies/site data. I ensured the Proxy mode in FF is set to "No Proxy". I do not have any extensions running or themes.

I am at a complete loss at what setting in FF I need to change to restore this functionality.

Thanks, Matt

This is a recent problem. I used to watch Peacock on Firefox with my ad blocking extension. Now I cannot watch Peacock videos. The page My Stuff displays but once I click on a program or episode to watch, I get the error screen. (see words below) Even with no ad blocker, I get as far as an ad beginning, and then the error. I have already refreshed my browser. This did not help. I can watch Peacock on Edge. (PC windows 10)

ERROR MESSAGE: Something went wrong. Sorry, your system configuration is not compatible with Peacock. Please check the supported devices in our Help Center (6007).

I have a new macbook air running Sequoia 15.3.2, firefox is up to date, my battery which should technically last about 12 hours and I only get 5. Ran through everything with Apple and they said it is a Firefox issues. I don't have any extensions, add on etc. Thoughts?

In the last few days, the common Cloudflare widget required to login to many web sites has abruptly stopped functioning in my browser. I'm trying to diagnose what's caused it. I'd appreciate any suggestions or advice.

I noticed the issue on nexusmods.com, but I've confirmed it's a universal problem on ANY site that uses Cloudflare protection. I've continued to use Nexus as my test case.

Observed behavior: 1) The Cloudflare widget loads 2) It displays a checkbox noted, "verify you are human." 3) I click the checkbox. 4) It immediately begins "thinking" (spinny circle and "verifying...") for about nine seconds. There is an "error" message that appears during this, but no details are offered (see screenshot) 5) The widget reloads. 6) Go to step 2

This is an infinite loop.

Fixes attempted: - Disabling all extensions (uBlock, NoScript, Privacy Badger, Decentraleyes) - Clearing cache - Updating to the most recent FF build - Accessing in a private window - Changing DNS settings from Cloudflare to NextDNS - Disabling DNS over HTTPS altogether - Disabling HTTPS-only mode

During what I assume are high bitrate sections of YouTube videos (e.g. lots of movement, high resolution) YouTube will constantly drop frames.

Video for example: https://www.youtube.com/watch?v=KLuTLF3x9sA

I have tried: • Safe Mode • Installing the Flatpak and testing in that, which also has a fresh profile as I don't use the Flatpak version • Testing different related about:config settings – I can't remember them all now, but I tested every one I found googling that is related to the issue or hardware acceleration.

Hardware acceleration is for sure working. Turning it off makes the video drop to one or two FPS.

Chromium has no problem with the same video. However, you can see from the screenshots that both read the resolution/scaling of my screen differently, and it implies that Firefox is rendering something like 6314 x 3552 while Chromium is rendering at UHD, the resolution of the screen and my video. If I turn off all my Global Scaling, Firefox stops dropping frames (the same info box on YouTube states resolution is UHD), reinforcing my theory about scaling being the issue. Both are confirmed to be using native Wayland.

Went into Firefox and got the error message: Platform version 131.03 is not compatible with min version>=131.02 & max version>=131.02 So I'm thinking that the last update caused the error. I did a system restore to a week earlier, and after 5 hours, the computer rebooted to that date. Upon opening Firefox, I found the the notice that the next time Firefox opens, it will update. After closing, and reopening, Firefox updated and displayed the same error message. Nor quite sure what to do, I downloaded Firefox again, and was going to uninstall and reinstall. But as soon as the download finished, it loaded. So now I have the new Firefox without all of my saved bookmarks and passwords. I thought I'd read someplace that that wouldn't happen, and all of my password and bookmark history would transfer to the new Firefox. As if that wasn't enough to ruin my day, I found that the new Firefox isn't working in my wife's account on the same computer. She gets the same error message as I did before the new install. I know, my fault for not backing up the bookmark and password files, but what's my option now?

I cannot use Firefox or Thunderbird I keep getting an error code: PR_CONNECT_RESET_ERROR The problem started straight after the latest update a few days ago.

I have cleared the cache and cookies I turned off the addons and extensions I shut down the internet security I changed the proxy settings to "no proxy" I even changed cert9 to ccert9 and had firefox generate a new cert9

Nothing has worked.

HELP!

Try to get "tvlistingszap2it.com" --(which I have been using for 5 years)--- but it opens "newsnation" Started doing this on 17 Mar, 25. What is wrong ?? Can you fix it ??

So I can open up Youtube no problem, scroll around and even hover over a video for the preview. However the moment I click on a video the tab will crash. I check if this was the case for other video streaming sites. HBO Max has the same issue while Amazon prime doesn't crash however has a message saying there is a problem with the video player. Now I checked if videos can work on another browser (Microsoft Edge), and there are no issues. I have cleared the cache, disabled extensions, checked for updates [update to date: 132.0.1 (64-bit)], restarted Firefox from troubleshooting mode, enabled autoplay, checked if videos work in private mode, updated my graphics card driver, and even checked if Firefox's volume is muted (its not).

Youtube just does not run well on the firefox browser, I have had this issue on my pc, as well as my laptop. Twitch, piracy streaming sites, 9anime all work fine this problem with loading and buffering is exclusive to youtube. I have tried resetting my firefox settings, changing the values for load times and resource usage in about:config and none of these have fixed my youtube.I have tried multiple fixes I've been recommenced by online forms. I have switched my user agent to make youtube think I am using chrome, I have disabled and removed all of my extensions including ublock origin, and loading youtube remains painfully slow. In fact, disabling adblock makes the load times even slower.

Also responding to my post with "hmmm durrr it works just fine for me" does not help anybody, stfu.

Today: DevTools crashed many times, and I’m facing unusual issues. I cannot call through Messenger and cannot connect for video calls. Also, DevTools is not working, even though Firefox Developer Edition is quite good and healthy. Even Firefox is not working well. Please fix this issue quickly.

OLD ISSUE

My Firefox is using a lot of data; I don’t know why.

I am not using Firefox, and it is not running in the background, yet it is always using the internet. So what do I need to do in this situation? I tried to stop the internet connection using outbound rules, but it did not work. It is still using the internet. What is the reason my browser has high data usage? I have high data usage; in fact, in the past 12 days, we've used 30+ GB of data.

Since the recent update to Firefox 131, I can no longer use the Billpay option of my TD Bank account. I am able to log into my account without any problems and use all of the options except for Billpay. I want to add that I know I am not alone with this problem as I have seen several others with the same problem but with different banks. It is the Billpay option which no longer works.

As I said, the bank site is fine until I click on "Billpay", Then I get this: begin quote: "Why can't I access Bill Pay?
