Firefox Community Forum

Hi. I am running a 3 monitor setup and I like to keep open quite a few tabs. And two windows of Firefox. So two Firefox instances with several tabs on each. But because it eats a lot of memory, I have to close and reopen Firefox from time to time. And to my annoyance, sometimes it "forgets" about one of the windows. So opens only one instead of both. Therefore I loose some quite important tabs. Any suggestions on how to fix this? Thank you.

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

We still use some Dell 13g servers equipped with idrac 8. When I'm trying to launch the virtual Console the window opens up but nothing shows. This used to work fine in previous versions of Firefox. I can't tell from which version it stopped but it's not long ago. Also idrac 9 console works fine in Firefox When trying to open console idrac 8 in Chrome it works fine Any idea what could be causing it? Any config switch to tweak?

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

Every few hours, maybe 4 times a day, XULRunner appears and tabs me out of everything. It says "This profile was last used with a newer version of this application. Please create a new profile."

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

The browser takes extremely long time to start-up. Task manager shows that it's trying to pull some 200mbs of data at the rate of 0.5mb\s or less. RAM is fine. HDD is old, but recently defragmented and, outside of <this> particular issue - it's not a problem. System is dusty, but system is system. For some reason virtually any other program launches more or less just fine. A particularly heavy game can pull gigabytes of data in about the same time that Firefox is bottlenecked to kilobyte speed.

It's not a conflict of start-ups, I have only the driver necessities in there. it's not a windows start-up issue, the browser can take as much time even a minute after windows is loaded. It's not a (anti)virus. Because I don't use either. It's not some 15 year old Celeron trying to handle W10, FX8320 should be able to handle opening a web browser. It's not a ton of extensions, and it's not even Firefox accounting, it happened before I registered. From extensions it's only ublock origin and VPN.

My personal three guesses are:

-More than 3-5 tabs on average, but, last I checked, the tabs aren't loaded upon start-up. And power users have sessions of dozens of tabs. -100-200 bookmarks. Again, not sure how hard is it to read a text data, unless it also has to load some thumbnails or icons or whatever. -Software aging.(Latest stable firefox, updates are on, and it has been running far less than this 4 year old system)

Reinstalling the system isn't a solution. Nor is reinstalling Firefox. Nor is dumping bookmarks, because otherwise why bookmark them. I'd just like to know why is Firefox limited to kilobyte speed of initial page loading. It can't be a damaged HDD cluster, otherwise I'd feel it outside of start-up.

With my limited knowledge of PC - it's usually a random read issue. Because like every memory benchmarks(HDD and RAM) can show hysterical speeds when loading\copying some 50gigs of a single file, if it's a few hundreds of thousands of small files - it becomes random and tanks. But what I don't understand why does Firefox have THAT much clutter? Is it really the bookmarks?

Hello,

I have a problem with Firefox on Linux, doesn't seem to be distro specific as I've tried Manjaro/Ubuntu/Neon, when using KDE in that when listening to music on YouTube music my computer will go to sleep after the elected time. On KDE you can see which applications are preventing sleep and/or screen lock, other applications are listed here but not Firefox.

When playing a video everything works as expected.

I would investigate myself, but I don't know where to start so if someone can point me in the right direction or offer any insights?

Currently using: KDE Neon KDE 6.0 Kernel 6.5.0-21 Wayland

For over a month now i have a problem with youtube. It loads videos very badly. I have good connection speed, but 0 network activity and 0 buffer health in Stats For Nerds on youtube and videos dont load. I can wait for 10-15 minutes (but sometimes they load almost instantly) before video load 40 sec buffer and after that buffer ends i can wait for another 10 minutes befor it load buffer again.

This problem persist only in my firefox on my computer. I tried deleting all the extensions, reinstalling firefox, "refresh firefox" future, changing useragent, reinstalling windows (it was the time anyways) but it doesnt solve the problem. I dont have this problem in other browsers (edge, librewolf, chrome) on my computer.

OS: win 11 x64 Firefox 127.0 x64

Ever since the update, I have had pink flickers on videos on youtube and twitter. They last for less then a second, so I couldn't grab a screenshot of it. After doing some reading online, I turned off hardware acceleration which turned the pink flicker black and now effects several sections of the web browser.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

Hi, i just got a new laptop (Asus Zephryus G16, 2560 x 1600 screen) and after installing Firefox there is a thin white border to the left of the screen when running in fit screen. This problem is not present when in a windowed mode or in F11 full screen.

I tried updating the Intel Arc drivers but this did not fix the problem. Changing to compatibility mode also did not fix te problem.

PS: in the uploaded screenshots it is quite dificult to see the white line(because the background is also white), but when the image is viewed in a new tab it is visible.

Thanks

Dear Firefox Support Team,

I hope this message finds you well. I am writing to seek assistance with a persistent issue I have been experiencing in my Firefox browser. Despite my efforts to troubleshoot, I have encountered problems with various animations within the browser.

The specific issues include:

  Text Selection Animation: The animation for text selection does not function.

   Element Overflow Scroll: The animation for scrolling within elements in overflow does not work.

   Developer Menu Resizing (F12): The animation for resizing the developer menu (F12) is not functioning.

   Button Hover Effects: When hovering over elements such as buttons, the expected CSS :hover modifications do not occur.
   The cursor remains the same regardless of where it is moved. This is particularly problematic as the cursor often retains the icon corresponding to editable text even when over buttons.

Additionally, there are complications when resizing the browser window. Upon resizing, the window seems to "half" itself, making it impossible to drag or further resize. This behavior also hides the three standard buttons present in all windows.

An additional symptom is that when I initially open the browser, it functions perfectly. However, during usage, the first indication of a problem is the disappearance of the mouse cursor, requiring movement for a couple of seconds. From that point onward, all mentioned issues begin to manifest.

I have taken several steps to address these issues, including:

   Complete Firefox Reinstallation: I uninstalled and reinstalled Firefox from scratch in an attempt to resolve the problem.

   ESR Version Testing: I experimented with the Extended Support Release (ESR) version of Firefox, but the issues persisted.

   Hardware Acceleration Disable: I disabled hardware acceleration to check if it was causing the problems, but the animations still did not work correctly.

Despite these efforts, the problems persist, and I am reaching out to seek your expert guidance in resolving these issues. Your assistance in this matter is highly appreciated.

Thank you for your time and consideration.

Best regards,

Ivan Beltrame

Using the arm64 version of Firefox on a Surface Pro X causes several graphical issues. These issues started either with a update of Firefox or drivers.

This topic has already been reported, please see here for more information and documentation: Reddit: https://www.reddit.com/r/firefox/comments/182iojx/firefox_arm64_graphical_problems_on_surface_pro_x/ Mozilla Connect: https://connect.mozilla.org/t5/discussions/firefox-arm64-graphical-problems-on-surface-pro-x/m-p/52086

What can be done to report this issue and help it getting fixed?

I am using the apt version of firefox v125.0.2 (64-bit). I do not have a dedicated GPU - I use my intel core's internal gpu only Intel Corporation HD Graphics 620 (rev 02).

I used to play this game named narrow.one, which before I reinstalled the mentioned libraries, was working fine except for crashing a few times. I thought these libraries were causing some issue, so I tried reinstalling them.

I reinstalled the libraries using: `sudo apt install --reinstall --fix-missing libgl1* libegl*`

After installation, I start getting that error. So, I tried reinstalling firefox (using the same command), and then restarting the laptop - but of no use. Chrome seems to be running WebGL, including the game.

In firefox, on the https://get.webgl.org/ page, I see Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.

After that, I also tried reinstalling `libopengl0` and `libglu1-mesa` and `intel-microcode`, but of no use. Running although, `sudo intel_gpu_top` and then chrome, it seems that the GPU is in use by chrome as well.

I then go to about:support. It shows me the images I have attached. Reading the logs, there several `blocklisted` values in `Decision Log` section. I suspect that's the cause of this issue, but then I don't know how can I un-blocklist the blocklisted things, and even after that, why does Chrome runs webgl if these are blocklisted?

Running `glxinfo -B`, I get the following: `name of display: :0 display: :0 screen: 0 direct rendering: Yes Extended renderer info (GLX_MESA_query_renderer):

   Vendor: Intel (0x8086)
   Device: Mesa Intel(R) HD Graphics 620 (KBL GT2) (0x5916)

   Unified memory: yes
   Preferred profile: core (0x1)
   Max core profile version: 4.6
   Max compat profile version: 4.6
   Max GLES1 profile version: 1.1
   Max GLES[23] profile version: 3.2

OpenGL vendor string: Intel OpenGL renderer string: Mesa Intel(R) HD Graphics 620 (KBL GT2) OpenGL core profile version string: 4.6 (Core Profile) Mesa 23.2.1-1ubuntu3.1 OpenGL core profile shading language version string: 4.60 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile

OpenGL ES profile version string: OpenGL ES 3.2 Mesa 23.2.1-1ubuntu3.1 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20`

I do not know much about OpenGL, but reading the above stuff, I suppose my GPU is in use and also has a compatible driver (although I am not sure).

Also, running `glxdemo`, `glxheads`, and `glxgears` seems to be rendering stuff.

Should I reinstall firefox after purging it first? Please help.

Thanks!

Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.

Sorry. We’re having trouble getting your pages back.

We are having trouble restoring your last browsing session. Select Restore Session to try again.

Today I started getting repeated notifications, every 5 to 10 min or so, that my McAfee subscription has expired, my credit card has been rejected, and that my computer is infected. I do not use McAfee, either in Firefox or on my computer. I use the security suite that comes with Windows. I cannot stop these messages from appearing, and disabling notifications from McAfee in the messages does no good, the notifications just keep coming. HOW DO I MAKE THEM GO AWAY? They must be SPAM because I've never had a McAfee product on this machine, EVER. Thank you so much for the help, Dave Templeton

I have noticed a bug with how the Firefox icon appears when launched in the Windows 11 taskbar when the never group option is enabled. When Firefox is launched and is the only application open in the taskbar, there is no label present next to the icon like other programs have when launched. There is the little line underneath the icon though indicating it is launched but that is it. As soon as I open another application though, the label will also appear for Firefox. This is only a minor annoyance but is definitely as bug at least for me and should be pretty easy to fix. I will attach screenshots of the behavior. In the first screenshot, you can see that Firefox is open but has no Text label like it is supposed to. The second screenshot is as soon as I open a second application.

I am on Windows 11 Home 23H2 Build 22631.2792 Windows Feature Experience Pack 1000.22681.1000.0 Firefox Version: 120.0.1

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks
