Firefox Community Forum

Hi everyone,

I’m running into a performance issue specifically on Firefox that I can't replicate in Chromium browsers.

On my site https://snippingtoolshortcuts.com/, the layout and text load fine, but the scrolling performance feels "heavy" or jittery on Firefox (Version 133+). When I test the same page in Chrome or Edge, the smooth-scrolling and hover effects on the shortcut tables are perfectly fluid.

I’ve tried:

Testing in Troubleshoot Mode (Add-ons disabled).

Disabling hardware acceleration.

Checking the "Network" tab for slow-loading scripts (everything seems green).

Are there known issues with Firefox's handling of large CSS tables or specific grid layouts that might cause this? I'd appreciate if someone could check the URL on their end to see if it’s a global rendering issue or just something with my local profile.

Thank you.

I am finding that occasionally using Firefox on Windows 10, that the Facebook page stops and wont let me open or upload files and AOL mail disappears although the site is open. If I go to using MS Edge both sites are OK.

I love Firefox but may have to stop using it as my default.

I can do what you advise but one single website is not accessible due to JSON problem block tried devtools.sjonview.disabled did NOT work. https://www.ancestry.com/

I suddenly can not sign in to my bank account. Started last night (12/22) and continues this morning. It worked fine yesterday morning (12/22). I can login in using a non firefox device without issue. What did firefox change and how do I fix it?

When I try to view my emal, I get following messages: bold textAccess Denied You don't have permission to access "http://att-yahoo.att.net/FIM/sps/ATT-Yahoo/saml20/login?" on this server. Reference #18.85f4d517.1766671077.26d715ea

I downloaded an update for Firefox email on my PC and ever since when I try to access my email, I just get a blank page. I still get my email on my cell phone and kindle.

Hi,

I am trying to use the website Jpay to connect with a loved one in prison. When accessing jpay's website I am prompted to enter my username and password in order to access the account. I enter the correct information- select login and the page will attempt to load and redirect me to the next page, but unfortunately nothing happens. The page will flash and prompt me to enter the username and password again. I am able to login into my Jpay account using safari, edge, and chrome however those browsers are no longer compatible with the jpay server for video visits. To add- I have purposely input incorrect details and when the page redirects it advises that I have input the incorrect username and password. Lastly, I have tried using several devices that range from a laptop, two different iphone, an ipad and an android tablet, the issue remains the same firefox will not redirect beyond the login screen. I have contacted jpay directly and there is nothing they can do. Please provide any advice on how to fix this issue. It appears to be on the back end. I have attached two snips. One showing i entered my information and clicked login. The next shows my username and password has disappeared after the failed load/ redirect. Thanks!

For some days now the Guardian (UK journal) website can't be loaded. It's specific for Guardian, I have no such problems with other sites, and I don't have this problem with Guardian with Chrome. I've erased cookies and caches, restarted my computer, to no avail. I'm using version 146.6.0 of Firefox on MacBook Pro 2020 with Sequoia 15.7.1.

My account was tagged/blocked by Mozilla. The account at issue has 2 factor enabled. I have a landline but now it will only text to authenticate. I had a school e-mail account but they changed and upgraded and dropped all accounts except for new/continuing students without notice (basically everyone until registration). Bottom line my phone was disabled by one vendor and my recovery e-mail by another. To access the microsoft store to correct an issue it required a new passkey. I submitted one. Now mozilla has blocked my password and microsoft requires me to login to contact the store or support but of course my issue is logging in. Around and around I go. I cannot correct a charge, microsoft is free to use my credit, and I have no way to notify anyone that something is amiss with the charge ( paying for a service already purchased, ie. double charged. I also noted a comment about that request being from outside the continental US, but have no ability to contact anyone nor to check/access my account. WTF

For awhile now I have trouble completing purchases on some websites when using Firefox. I need to open another browser like Edge to complete the transaction. Anything using "Shop with Visa" doesn't work and, for example, I just had to buy tickets on StubHub through a regular credit card submission. I bought them 4 times, got confirmation, and then had the order cancelled because it didn't go through. I called my credit card and was on with StubHub tech support. The final solution was to open Edge and make the purchase and it went through and I had the tickets a minute later. I'm now having the same issue trying to make a reservation at a restuarant through sevenrooms.com Its been sitting on the confirmation page for several minutes. I went into edge and made the reservation and it was confirmed with 30 seconds.
