Since the last update, I believe, because this error occurs constantly and with EVERY video. This is often, not always, the case immediately after updating FF. Now it was fine for a while, but now it's so bad that I'm having trouble watching YT videos properly. Reason: Browser open, logged in to YT. I click on a video to play - video opens, plays maybe 10 to 20 seconds, then playback stops spinning top, I also found out during the last glitch after update that if I switch the resolution briefly, higher or lower doesn't matter - important is to leave the current resolution and switch to another one. And oh wonder - immediately, instantly with the change, the video starts playing. If I wait for this - without doing anything myself, it sometimes takes 30 - 40 seconds for the video to start ... sometimes it just "hangs" ... This is extremely annoying - if it doesn't work, I have to switch browsers... What is also extremely annoying is that it occurs almost regularly after an update ... until the next one possibly, for unknown reasons, does not fix the error, but sometimes mitigates it. Now, however, the disruption/interruption is so massive and totally annoying that I'm thinking of switching. I'm just tired of it ...

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

I went to my favorite web site this morning (dpreview/forums) and when it displayed I must have accidentally clicked some Firefox thing because the page was then overlaid with a thin orange highlight with the word PICK on it. I tried moving the cursor off the page but it only changed which segments of the page were highlighted. So I clicked and the page was replaced by just the menu section of the page, apparently that was what was highlighted when I clicked.

Now, no matter what I do, when I try to go to that url only the menu is displayed, the normal list of forums is missing. I've restarted FF. I've rebooted. I've cleared cookies and cache. I've refreshed the page. Nothing helps. Other web sites are fine. I can't imagine what this is for. A diagnostic tool or accessibility thing perhaps.

Please help. I'm running latest FF on latest Win 11.

Firefox has stopped obeying target="_blank"

Started a month or so ago.

Take a look at Firefox target="_blank" problem for details.

There is not a topic in the dropdown list that remotely addresses this issue so I just selected Performance and Connectivity for the hell of it.

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

Some Firefox option is adblocking some links in Publishers Clearing House emails. The same emails work OK in Safari. There are no adblockers (now or ever installed) on this Mac. It's not the end of the world for me but it should be fixed for possible future use.

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 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?

Late last week I updated Firefox to the latest version. Ever since, I keep getting the same error message that I typed in the subject line. I've seen previous recommendations on how to correct it, but none of them work, probably because there's been more updates since what I've come across. I'm getting this error message on multiple sites, including my bank account and my business email account. I'm presently typing this on a different browser (Brave), because I was getting the same error trying to find answers using Firefox.

Any assistance would be appreciated; thanks.

System: Linux/Fedora41 Firefox: 136.0.4 Monitor: Acer 27" 1920x1080

When I open a FF window, it opens full screen vertically and to some width horizontally, both dimensions not desired. My usual style (for the MANY years I have used FF and Linux) is to use a FF window that is NOT full screen in either dimension since I normally have multiple windows open simultaneously. This FF behavior has started just recently.

This behavior occurs when starting FF from the FF icon on the desktop, when opening a new window from the FF main menu, or when opening a new window via the 'Open Link in New Window". (Perhaps other ways as well: these are those I encountered.)

I have tried: .... Opening FF/resize window to desired size/close FF using 'Quit': no change on restart .... Deleting the xulstore.json in the profile folder/restarting FF: no change on restart

I would like to restore FF to its previous action: open new windows at the same size as the last one referenced. Can someone help?

Thanks.

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 ??

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.

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 am one of those old-fashioned guys who has a title bar on the main window, and inside this (from top to bottom) a menu bar (File/Edit/View etc), then the current set of tabs, then the address bar.

I can click in the address bar and the caret appears, but the moment I start to type anything to edit the URL the address bar jumps up to to the top of the window, covering up the menus and tabs, with a menu of suggested URLs that at times covers most of the rest of the screen. Some images attached to show what I mean.

This started in a recent-ish release -- it didn't use to do this.

How can I prevent this behaviour, so I can just edit a URL in place the way I used to without the address bar jumping to the top of the window?

Currently using FF 135.0 (64-bit), Windows 11.

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

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?

Hi, I have an HTML page - currently on the desktop PC - that contains a few graphics (they relate to IPA sounds) and a bit of javascript which will make the sounds play when the user mouses-over the graphic, and stop on mouse-out. The script uses <embed> tags. I know these arent favoured but I think they should still work, as they have in the past, so the script itself is fine. But there is no sound (obviously I have checked the src is correct and made sure the speakers are on and working. They are.) W10, FF ver 128.6.0esr (64-bit)

On websites, thumbnails will not display but appear instead as white boxes with small blue question marks. I am using a two year old ipad and my internet speed is 180.

This is a new bug, as of today.

If I click on each thumbnail the image displays just fine, but that is not ideal.

On a reddit forum, someone suggested typing about:config into the search bar but nothing happens when I do that.

Any ideas?
