Firefox Community Forum

Whenever I go to YouTube, there is a green download button, YouTube blocks whole page goes dark. No issue using Brave or other browsers. I use when trying to download a clip I'd like to keep watching to learn, without all the wasted overpriced data I disable the extensions apps I think relevant, then refresh, no change, disable popup blockers like Ghostery & Adblock plus, refresh, still no change.

Showed an example.

Using Windows 10 pro on Desktop, 64bit, internet is fibre optic as fast for rural, 16Gb RAM, 7TB Separate HDD's. Reasonably comfortable with pc use Been present for last couple of weeks, use other bought programs to download but unable to view prior on Mozilla, but works fine on other browsers

I play a game on Facebook - and i go to it from a link in my email - but today it says your browser does not support WebGL - this happened a month ago but I forget how it got fixed. :-(

it worked yesterday - and I checked for Firefox updates and it is up to date. last time this happened - I did read an article online that suggested to go to put about:support in the address window and under General it said to uncheck standard performance and to click on "use accelerated performance" - that fixed it.

This time when I go to about:support - "Use Hardware acceleration when available" is already checked. How do I fix it this time? and why does this keep happening every so often?

This just happened, (45 minutes). When I attempt to access a page or a file, when the page comes up on screen, it is a page of numbers and symbols. How do I remove these pages??

Since the update I performed today, 4/27/26, I am unable to upload files to my NAS via the Firefox web browser on a Windows 11 PC. I can still do it via the Google Chrome browser so I am not completely crippled, but it would be nice if I could still use Firefox for this work. Any suggestions on how to fix this, or will it require the software itself to be fixed?

I see this popping up, however my system is running on Windows 11, NOT 10. "Windows 10 reached EOS (end of support) on October 14, 2025. If you are on Windows 10, see this article."

I use an online weaving software (https://twistedthreads.org) and when deleting a row there's a popup that asks "do you want to delete?". I accideantally hit the checkbox that was along the lines of don't ask again and now even when clicking the button that would launch this pop up it won't come up (effectively meaning I can't use the delete button!) I've tried resetting cookies, and allowing the site to send me pop ups and it seems to have made no difference.

Sometimes, I cannot click on an option on a form (on my up-to-date Firefox, on Windows 11 - help, please! Its usually only when the options are shown as little buttons or squares to tick off. Its not my mouse because it works for the usual mouse works.

I can't enter the tick/click necessary on this form to say "Email me when someone answers this thread" Cheers, Carol

i've seen this before, in different older machines, but i can't remember the remedy. possibly a mouse-screen problem. it started with 150 i think...

Also in youtube, a gray layer covers the selections rendering mouse clicks impossible. clcking the logo, page reloads, but soon the layer covers most of the page. resetting graphics had no result.

thanks

i'm using mf 150

I have a problem trying to get the app PC Express past the sign in. The app is part of the yourindependentgrocer.ca app. I have used Firefox, Chrome and Edge and have encountered the same problem. I use Proton for my e-mail and I have used all their apps for my computer. I recently changed the start up app from judymk@protonmail.com to judymk@pm.me. I don't think this is a problem as Proton says the app should not care what protocol is used as it translates the same regardless of what app is used. I would appreciate any help with this.

I decided to try exporting my Facebook Messenger E2E encrypted chats, however I keep running into a variety of problems, because the process is simply badly written. By default, the process breaks when the website local storage data reaches 10GB - that is, as far as I understand, a Firefox limit. There is still plenty of RAM and disk space remaining. When the local storage hits 10GB, you get a "Quota exceeded" DOM Exception.

To get around that, I've changed browser.cache.disk.smart_size.enabled -> False browser.cache.disk.capacity -> 50GB (values in KB of course) dom.storage.default_quota -> 25GB dom.storage.default_site_quota -> 25GB browser.cache.disk.max_entry_size -> 256MB (seemed like some larger files were missing, like longer videos)

However the process still breaks, although I'm unsure if it wasn't a soft-limit by Facebook the last time (since it stopped downloading around 8,5-9GB, earlier than in previous attempts)

Are there more settings that could be limiting the export apart from those mentioned? I understand this is pushing the browser over the reasonable limits, however I still hope it is possible to override them for that one-off situation before reverting to defaults.

Bonjour, lorsque je veux me connecter à ma boite mail Zimbra de Free un message indiquant "chargement en cours" s'affiche après avoir rentré mon identifiant et mot de passe mais rien ne se passe, la page indiquant se message reste fixe. Pour info je ne rencontre pas se problème lorsque je me connecte avec Google Chrome. Merci de bien vouloir m'indiquer ce qu'il y a lieu de faire pour solutionner ce problème. Cordialement,

Lost Mozilla as my default browser after accidentally opening my Facebook page using Edge. The only site that is corrupted is Facebook. All others work properly. I still want Mozilla. Looks like I've created a newer Mozilla account even though I used my password to open my account using my email address and password. My profile name has changed. Wondering if problem occurs because account is shared with my husband and our account is under his name/email. Any suggestions appreciated. We do subscribe to Norton. Thanks.

Having issues with the browser often appearing distorted, text and images failing to load, videos showing up blank etc.

Problem disappears when in troubleshooting mode but after several refreshes the problem returns almost immediately, making using Firefox incredibly frustrating.
