Firefox Support Forum

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

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

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.

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

Hi, this is the same issue as as described here for Mozilla Thunderbird: 64bit Thunderbird issues with 64bit PKCS#11 drivers

– Firefox 122.0 (64-bit) – Windows 11 Pro 64bit (– Thunderbird 64bit)

Even though, I use a 64bit version of Firefox, it is not able to load any 64bit PKCS#11 module for security devices. Tried on several different PCs and several different 64bit PKCS#11 drivers for different smart cards.

When I try to load e.g. C:\Windows\SysWOW64\eop2v1czep11.dll for the Czech eID, it returns "Unable to add module". When I do the same from C:\Windows\System32\eop2v1czep11.dll, it works.

The issue is that some issuers of qualified and commercial certificates (like e.g. Komerční banka) do not issue a 32bit version of PKCS#11 drivers for their smart cards anymore and the only driver available is C:\Windows\SysWOW64\mopkcs11.dll, which cannot be loaded by Firefox or Thunderbird either.

I don't see a problem in implementing the support for 64bit PKCS drivers in a 64bit browser and a 64bit email client. And if it does have the support, then there is something wrong going on.

When I try to screenshot (Windows+Shift+S) and paste the screenshot into Google Translate, I get the error message:

Unable to paste from clipboard right now. Try copying the image again.

This functionality works in every other browser I've tried (Chrome, Edge, Brave, Opera GX), so it's not a Google problem, I don't think.

I feel like I've been seeing people online complaining about this for a couple of years now, and it's shocking to me that I still couldn't find a solution in a thorough google search. Has anyone found a fix for the mandatory restart Firefox now pushes whenever there's an update available? Basically, out of nowhere, the program will refuse to open any new tabs or load any pages, instead giving the error message in the image. A restart is forced, and all private tabs are lost without warning. This is completely unacceptable browser behavior. As far as I know, there is no setting or about:config option that will fix this. Has anyone found a work-around?

I've been a loyal Firefox user for a couple of decades at this point, but this nonsense has me seriously considering switching to something else. Thanks for any help anyone can offer.

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

Audio has stopped working in Firefox only. Audio is working for Windows/PC system alerts and playback in all apps and browsers except Firefox. Perhaps after a system update....I'm supplying the answer to this in replies. I had to re-ask the question because previous versions of it with incomplete solutions have been archived and do no allow more input. So, yes, I'll be answering my own question. Just for you. XXOO

When I attempt to post comments to yahoo articles from firefox browser the last week or so I keep getting a "fail to post" error message. I've tried from several computers and get the same error. I've also posted using other browsers and my posts go through so this is clearly a firefox issue, likely some bug from a recent release. Please let me know how to fix this bug.

It worked nicely for many years, until today. I installed Supraland from Steam, played for a couple of hours, and suddenly my Youtube page went glitchy - not the layout but minor elements were getting scrambled, especially text. I'll attach a couple of pictures to show it. In fact, all pages glitch if their content changes even a little. As of typing now, I see the glitches, with a word or another getting butchered. Gifs and videos are full of that.

Windows 10, the current update, Radeon RX 580, the recommended AMD drivers installed (and reinstalled again and again, 23.11.1)

I think I did pretty much everything with Firefox. Disabling hardware acceleration fixes it (but then of course the browser goes slow). Games work fine, including Talos Principle 2 which is intense enough. The clean install, reinstall and all that. I'm writing from the beta stable build now. I've tried to regress to the previous versions too.

It strictly coincides with the game installation but I have no close backups - who knew that some game might just do that. Then, of course, I tried to uninstall it too.

Thoughts?

As the title says Cloudflares Human Verification Captcha doesnt work on this browser forcing me to have to use 2 separate browser to circumvent the issue which is annoying. basically when I click on the verification it goes into a loop of trying to load the captcha then asking me to click it again for it to only repeat the process until it gets stuck on a several minute loading before telling me it failed to load with no error message. Eventually stops even trying to do the loop and does right into the minute long loading and failure to load message. I have found no help for this online and im not tech savvy enough to be able to fix this issue on my own. things ive tried 1. making sure firefox and all extensions are up to date 2. completely restarting the browser 2. disabling all extensions on the site 3. tried private window 4. tried other web browsers (it only effects firefox)

Merry Christmas 4 days Early!

I would like to stop the continual suggestion to update my password at login, yet be able to use the saved password at login.

Would you please add this fix?

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.
