Hi Firefox Team,

I wanted to ask, whether you know any solution to my streaming problem. I noticed that my download speed is incredibly fast, when I am running a download in the background of my PC. This can be a windows-update or updating a game via steam. But when I am not downloading anything, then Youtube cant even stream 360p without buffering every 10 seconds. I feel like the Firefox-Browser is not telling my PC that it needs the internet and thus does not get it, but when another program needs internet, It gets enough to work.

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.

When using any dark Firefox theme on ChromeOS, the contextual menu text and background are both dark. This means there is little to no contrast, and so the text is very difficult to read.

Unfortunately, the ChromeOS screenshot tool doesn't work on Linux apps, and so I'm unable to share a screenshot. Tested using several dark themes, including the default -- behaviour was consistent in all.

Firefox installed using the official package through the built-in ChromeOS Linux VM "crostini". Issue has been reported by other users on other platforms in the past, so this seems to be a long-standing bug.

Dear Sir/Madam

On my main desktop computer whenever I try to open a Channel page on YouTube, Firefox will start to lag and either tell me it is slowing down Firefox and I need to stop the tab or just crash.

Sometimes after I refresh a random number of times, it will load the videos tab and then be fine on that channel. On other occasions it will never load the channel's Home page or Videos page and I have to close the tab because it won't load or change.

This only happens on my desktop computer. It it more likely to happen if the page has a home screen video.

Let me know what you think. Thanks

Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

I have 3 devices connected to Mozilla account, 2 smartphones and 1 PC and NONE of them are syncing properly, bookmarks sync perfectly and everything else fails miserably. Some part of history does sync but nowhere near the full history. Syncing of open tabs is *completely* broken.

Unsure which 'topic' deletion applies to. All of a sudden I am unable to add or delete from my bookmarks and I think I may not be able to delete anything anywhere else either. Why has this occurred, suddenly, and how can I fix it without hiring an IT pro? I have been using Firefox as a browser for over twenty years and this has never happened before. I am using Windows 10 and Firefox 146.0.1. Thanks, James.

I don't understand the reason Firefox is slowing down and making my emojis and GIFs on LinkedIn very difficult to access. This isn't a problem on other sites. Any solutions? Thank you for your consideration. marlem388

Hi i saw something saying the browser wanted to use more ai etc, is this true? Is there a way to opt out of these services in total if so?

I use firefox for the privacy and to avoid bloatware so itld be really disappointing if its now looking to use ai more in its services.
