Firefox Support Forum

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.

Hi Mozilla - I just wanted to report some recent phenomena. In the past couple weeks Firefox, and related Private Browsing browser, seem to have developed consistent hangups in fetching data across a pretty wide range of sites. Both my banking sites will not load after logging in to them, just spins and spins. Also some very general searches will not load any results for minutes at a time, I just give up and kill them. I've uninstalled/cleaned/reinstalled latest version, etc, etc. By comparison, these same data fetches in banking sites, etc, work dandy in Duckduckgo browser, which is also a heavy no-trace browser. This ominous to me as I really like Firefox and do NOT want to have to resort to Edge. Duckduckgo browser is very good but doesn't have nearly the menu or favorites sort of features that Firefox does. Can you investigate? This is typical Win 10 system in Lenovo i7, been working like a champ till just recently, no system changes. Thanks.

I using an ASIS Latop model X756U running the Windows 10 Operating System. Firefox is my default browser.

I installed the Opt-Out Google Analytics Extension on 9 June 2024. The intent was identify which of my applications are using Google Analytics by testing them and seeing which ones were broken.

Having done that I removed the Opt-Out Google Analytics Extension from the Firefox Extension list.

Unfortunately the extension remains active and continues to disrupt my browsing experience.

How do I remove this extension permanently?

I lost my Outlook365 with the latest Windows 10 update. When I reinstalled I went through the preferences to select Firefox as my default browser. I have been using this for years and every time I picked a link in an Email it would open a new tab in my existing browser.

Now, regardless of anything I try it continues to open an new Firefox browser, with pages included since this started on the weekend.

What settings am I needing to make to correct this. I have gone through the config settings and selected 0 in the browser.link.open_newwindow.restriction with no success.

Hello there,

I am using WordPress, and the Video Player Element does not display on Firefox, although in HTML code is visible. The same problem appears in Firefox troubleshooting mode if it helps.

Do you have any idea what causes it, and how can I solve it?

Hi - I updated my Firefox / Mozilla browser yesterday and now all types of downloads are failing. PDFs and EXEs alike. I can't an error that says Failed.

And yet, when I use Chrome or Edge, the downloads work fine, soooo - not sure what is going on.

Can you please assist? Thank you!

Firefox: 127.0 (64-bit) Windows 10

Hi everyone,

I run an online barber supply store called Magnus Supply (https://magnussupply.com/) where we offer a variety of products including clippers, trimmers, shavers, grooming products, accessories, and sanitation supplies. I'm always looking for ways to improve the user experience on our website and streamline our e-commerce operations.

Can anyone recommend browser extensions that could help with:

Enhancing website performance and speed. Improving user engagement and retention. Simplifying the checkout process. Better tracking and analyzing customer behavior. Ensuring data security and privacy for our customers. I’m particularly interested in extensions that work well with Firefox, but suggestions for other browsers are also welcome. Your insights and experiences would be greatly appreciated!

Thank you in advance!

This is really annoying. I've had that feature disabled since I first started using Firefox as I feel it defeats the purpose of incognito tabs to make it obvious when you have them open, and I prefer keeping all my tabs organized in a specific way

I've checked about:config and that feature is still set to false, I've checked about:studies and there's nothing that looks like it would impact private browsing. I've tried restarting both Firefox and my computer, the tabs are still separate

Anyone have any ideas on what to do now?

I keep getting a popup about using an older version and creating a new profile. I already created a new profile a few days ago so I cannot keep creating new profiles every time firefox deploys a new version and would need to open firefox to update the browser version.

When I reboot a Windows 10 computer and click once on the Firefox icon on the Taskbar, (1.) Firefox does not open full screen although when closed it was full screen. (2.) A second Firefox window opens with Yahoo on a Tab and also not full screen. Please fix!

i keep getting sent to .ca sites instead of the .com that i had typed in and wanted to go to ie: yahoo.com discovery.com

There was no yahoo.ca or hotmail.ca when i got my email accounts and i only deal with originating networks Discovery.com not ripoffs like ctv.ca/discovery.

Whenever I try to download anything, it automatically fails. The problem just started recently and I don't know what could have caused it because I haven't done anything that could affect downloads to my knowledge. Things I've already tried are

• Reinstalling firefox (including full uninstall via "Revo Uninstaller"
• Updating firefox to the latest version (127)
• Disabled all firewalls
• Chose the save location
• Disabled all parental controls in windows
• Chose the "don't enable HTTPS mode" (https://support.mozilla.org/en-US/questions/1414064)
• Tried firefox & windows safe mode (https://support.mozilla.org/en-US/questions/1442742)
• Chose a different save location inside my computer (a folder other than downloads)
• Cleared download history
• Ran a chkdsk on windows

The thing is that everthing else of firefox works (browsing the web, watching videos, etc), it's only the downloads. It's also not a computer problem I think because I can download on other browsers (such as chrome and pale moon). Any help asap is appreciated.

For a while now, I've been having recurring issues with Firefox desktop freezing and becoming totally unresponsive. If there's any pattern to what causes it, I haven't been able to notice it; sometimes it happens as soon as I open the browser, sometimes it happens after several hours, sometimes it happens twice in ten minutes, sometimes it happens twice in a few hours (however, I can count the number of days it's happened less than twice in one day in the past few weeks on the fingers of one hand). When the browser freezes, it becomes totally unresponsive - it doesn't fade or display "Not Responding", and Task Manager shows nothing abnormal, but it doesn't accept any input at all, any video or other animated material that may have been displaying freezes, and it can only be "fixed" by force quitting from the task manager and reopening. This is exclusively a firefox issue; other programs open at the same time as the browser freezes are not affected.

The only real lead I have as to what could be going on is that sometimes, things don't freeze all at once, but in a cascading effect. For example, tabs, bookmarks, etc. might not highlight when moused over, but still accept the clicks, or selecting another tab might causes the address bar to display the URL of the selected tab, but the screen displayed in the window will not change. Once these cascading changes start, they generally progress to total freeze before I have a chance to do much with that information (only a few seconds), but it's unusual enough behavior to be worth noticing.

Things I've already tried that haven't fixed the issue:

• Reducing the number of tabs used and otherwise reducing Firefox's system resource usage has not impacted the problem in any way.
• Running in Troubleshoot Mode has not had a consistent effect on the problem (the most recent time I did, the browser ran stably for longer than I could stand to use the internet without my ad blocker, but this is only one data point in an already inconsistent spread; prior instances of the problem have occurred in Troubleshoot Mode)
• Disabling hardware acceleration has not fixed the issue.
• The issue has persisted through multiple refreshes and at least one full uninstall and clean reinstall.
• The issue persisted after creating and switching to a new profile multiple times.
• The issue persisted after renaming places.sqlite
• The issue persisted after clearing cache and cookies multiple times.
• The issue persisted after clearing downloads and history.
• And very likely some other stuff that I'm forgetting, I've been trying to fix this on my own for a while now.

The bookmarks disappeard on the toolbar or in the library even though the sites that were previously bookmarked are still marked with the blue star. Comically it still shows my recent additions even though they are nowhere else to be found.

On mobile the bookmarks are still there but resynching, reinstalling, restarting didn't work.

When i want to bookmark the disappeared ones again, they won't be saved and are gone again the next time I start the browser.

It's really annoying, I had a lot of them and I don't want to use desktop shortcuts or use another browser but I might just have to.

Firefox doesn't allow a web message to be sent but Google Chrome does. After filling out the form at: SPECTRUM URGENT: FUNDING FOR THE AFFORDABLE CONNECTIVITY PROGRAM IS RUNNING OUT, I could not send the message because I got a message saying, "Please enter a 5 digit zip code." but I did enter a 5 digit zip code! I copied the URL into a tab of Google Chrome and there was no zip code error so I was able to send my message.

I cannot register a credit card at: https://www.retailservicescommercial.citi.com/USCRSF/CMLSVC/index.html?siteId=PLCR_HOMEDEPOT#sec/signon

I was told eventually after clearing cookies and site data and refreshing the webpage that it doesn't work properly with Firefox and that I needed to use Google Chrome or Edge.

Can this be fixed or not?

Hi,

I can't watch live stream on youtube. I see only black screen on loading circkle. Ads working fine but after them i see what i said before. When live is over then i can normally watch it. I can watch twitch normally. There is problem olny on yt. best chris

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.
