When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

  • Rebooted my computer several times
  • Deleted my history/cache
  • Disabled my extensions
  • Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
  • Updated my computer
  • Updated my graphics drivers
  • Refreshed firefox
  • Uninstalled and reinstalled firefox (and rebooted my computer)
  • Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

Similar to the issue described in this thread (https://support.mozilla.org/bm/questions/1240674), I am unable to open Firefox - it simply refuses to open. I've tried multiple times, the option key, and re-installing. Nothing seems to work, which suggests something about my user settings is the issue, but a) I am not keen on deleting this if possible and b) I won't delete my user settings unless that is necessary. Like the attached thread, I am happy to attach crash reports, but without the ability to even open Firefox properly it's not obvious how I do this - force-quitting it just sends a report to Apple.

Any help much appreciated - I'd quite like Firefox working again.

My laptop is a MacBook Pro 13 2020 (Intel) running macOS Monterey (12.7.4). I installed the version of Firefox available for download as of writing (v127.0 based on Finder).

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

Windows taskbar doesn't unhide itself when firefox is maximised.

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

I just started having an issue while watching Live Streams on Youtube with FireFox. I'll load the live stream and it will run for about a minute then it will switch to the streamers previous recorded stream. I opened Youtube on my iPad and on Edge browser and the Live stream keeps playing the live stream but on FireFox it only lets it run for about a minute before flipping the playback to the previous recorded video of that streamer. I tried clearing my cache for Youtube and I have no extensions running. I have Youtube Premium and run no adblockers. I have also tried safe mode but the problem persists.

Any idea what could be happening?

Hi,

I am using Firefox for Linux, and whenever my yubikey is plugged in, firefox will start bothering me for a pkcs#11 password. It always happens on start-up but it gets relentlessly annoying if I happen to be on a site which potentially utilizes certificate auth, which I do not use this yubikey for.

I do however use it for 2fa, which does work perfectly fine.

How do I permanently stop whatever Firefox process keeps bothering me about this PKCS#11 password for functionality that I never use?

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.

Having Firefox open reduces all download speeds, upload unaffected

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.

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?

I cannot print from Firefox. It worked fine, and then stopped. I'm not sure what changed. It doesn't matter what printer I use. Even printing to PDF fails. No errors appear, and nothing shows up in the printer queue. All the other applications in Windows print just fine. It's just Firefox. And just for this one Windows user.

I tried clearing the saved printer settings in the about:support page. I tried refreshing Firefox. I tried uninstalling and reinstalling Firefox. I tried uninstalling, removing the mozilla folder in %appdata%, and reinstalling Firefox. No luck.

The only time I can get it to print anything is to log into a different user account on this same PC. Printing from Firefox seems to work then.

It seems there is some user-specific printer setting/file/whatever that is messed up. I'm not sure what else to try.

Hello, I've been trying to use my Firefox browser for the past week and nothing I do seems to work. Whenever I click the icon on my Windows desktop, it sends me the following Mozilla Crash Report:

We're Sorry

Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts.

To help us diagnose and fix the problem, you can send us a crash report.

I've restarted my computer and tried to change multiple settings, but the same pop up message keeps appearing. I've checked the box that sends the crash to Mozilla and clicked the button that says Restart Firefox, but still nothing. There's also a "Detail" button that provides a bunch of information that I'm not sure how to interpret haha but I can try to copy that if you think it would be helpful.

I would appreciate any help. I'm looking to get a new computer (not sure if that is part of the issue), but I'm really hoping to be able to save the bookmarks I had.

Thank you.
