Diễn đàn hỗ trợ Firefox

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.

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

Mozilla Support reports wrong version of windows? I have a screen shot. The web site reports win 10 when I have Win 11 Pro. The version check on this support page reports the correct information. So Mozilla website itself is out of date?

Updated Firefox browser on PC today and can no longer access my emails at https://outlook.live.com/mail/0/

When I log in to my Apple tv account on the Firefox browser, it comes up, but won't play the selected program. All other streaming services I subscribe to work fine on Firefox, as did Apple tv until this week. If I try running Apple tv on Google chrome on the same lap top, it works fine too. Ditto on my iPhone using Safari. I'd prefer staying on Firefox to stream Apple tv, but can't make it work at the present time. Can you help?

After updating to Firefox 147 from 146, it seems that some areas in page rendering are becoming corrupted.

Using the attached example from https://soundcloud.com/solarstone/tracks, it is possible to see a corrupted song bar. In the other song, where the full bar chart should also appear, there is a black area, which seems like a different kind of corruption where the content is simply not being displayed.

This did not happen in version 146.

Is there anything I can do, or any information I can provide, to help debug this issue?

Thank you.

When attempting to sign in to my social security account I get the following message: Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have been using Firefox for many years and I was satisfied with this browser. For the last 2-3 weeks I have had a constant message that reads

I did everything, I deleted, I enabled cookies, cleared cache, but the next day the same message is repeated again. I'm tired of it because I have to retype my passwords every day and I'm close to permanently using MS Edge which serves me perfectly fine. Please give me the correct instructions on what to do to get Firefox to load my email normally again or I'm really going to quit Firefox forever.
