При нажатии на ссылки некоторых сайтов выходит страница с адресом, но содержимое пустое либо белый экран окна, либо черный, в зависимости от сайта, ничего не смогла понять, другие сайты открываются отлично. Например notion открывает черной страницей, мой газ https://мойгаз.смородина.онлайн/ открывает белым, mail.ru открывает но дальше все письма внутри начинает открывать чистыми вкладками. И это происходит не зависимо от того включен VPN или нет, загружает одинаково, произошло сегодня после перезагрузки компьютера. Сайты рабочие, проверено с этого же компьютера но другими браузерами. Как решить проблему? Это малая часть сайтов которые не работают.

Sometimes when I click on a stored bookmark all I get is a white page and no info.? when this happens I right click on the firefox icon in the taskbar and go to a new private window and after that I can get to the bookmarked site. wondering why this happens at times. I am using windows 10 for now but am planning to build another computer with windows 11 in the future.

Recently I’ve been unable to play YouTube videos on Firefox: “Video unavailable.”

I’ve tried clearing the cache and cookies, and restarting Firefox in safe mode. I’ve disabled “Use recommended performance settings” and “Use hardware acceleration.” Still no videos.

I’m using a VPN and have several Ff extensions - none of them video related.

The problem seemed to start after the most recent Firefox update. YouTube works fine in Safari.

Thoughts?

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.

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’m experiencing an issue in Firefox where a web-based application loads the main interface, but the interactive content does not appear or remains blank. This happens consistently when the site is accessed through a CDN, while direct access to the origin server works correctly.

The issue seems related to delayed or timing-out requests (similar to a 524 timeout), where dynamic content fails to load within expected response times. Static elements render properly, but anything requiring API or server-side processing does not display.

This behavior also affects browser-based puzzle apps like Spelling Bee, where the gameplay area may freeze or fail to load entirely in Firefox. I’ve tested across multiple networks and devices, and the issue persists only in this routing setup.

Has anyone experienced similar rendering or loading issues in Firefox related to CDN timeouts or delayed responses? Any troubleshooting tips or Firefox-specific settings that could help would be appreciated.

Normally, I use the FireFox browser to access my gmail.com email account to view my messages. I am not sure what changed, but now when I enter gmail.com on my FireFox browser, I am not getting any response. I do not get the gmail display where I would view my messages. Additionally, I am not getting any error messages, all I get is a blank screen.

Is there any advice you can provide to help me resolve this issue ??

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?

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

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.

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.

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??

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.
