Firefox 社群討論區

Recently I've had this issue (on reddit) where after I expand a video in the feed, and start scrolling, all the visuals freeze.

I know it's only the visuals, because I can still interact with the website (usually unexpand the video, or pause it) with the image still frozen and audio still playing.

I can fix it by tabbing firefox down, and then up again. While researching I found the profiler, and finally managed to capture the moment it happened.

I'm no stranger to technical stuff but it's a loooot of data to process, I did a "clean" profile recording as well where I did the same action and where it didn't freeze, and I can't really make heads or tails out of what the issue is.

The recording managed to capture the phenomenon and I only clicked twice during that period, to expand two reddit expando videos, the second one is what caused the issue when scrolling. The only thing I see is a spike in memory usage

Not sure if I can (or should) upload the profile recording here or what, but it's been bugging me a lot.

It's pretty tricky to replicate because it seems to be random when and what triggers it, even expanding the same videos doesn't replicate it. Sometimes I go days without it happening, sometimes it happens 6 times in a single session.

I've added some screenshots of various views of the profiler/stack data.

I have an Nvidia RTX 5070ti GPU, hardware acceleration is on, AMD Ryzen 7 9800X3D processor.

I think I might have enabled some rendering settings in about:config, maybe it's related to that but I don't remember exactly what.

Maybe it's due to some windows "game optimisation" or the GPU and CPU-GPU fighting?

I have no problems watching videos while playing games or anything though.

I can't login to my Facebook account? But I can login to other browsers,

Can you please help me on this.

Thanks.

after confirmation and approval nothing changes on screen.

If synchronisation works bidirectional - does that mean that all bookmarks vanish on all added computers when they are erased from one of them? Can and should one define one of the computers as the one from which the installations should be preserved?

Running Firefox 140.8.0esr (64-bit) on Windows 10 Pro on an HP laptop. The feature/problem described works properly with Chrome and Edge. The problem occurs when accessing the following article:

If the window is set wide enough, there is a sidebar displaying, "Share this content in X". If the screen is squeezed down (i.e. drag the right margin to the left) far enough, the sidebar will disappear. That feature is handled properly, but as the window width is increased and the sidebar appears, the main body of text does not wrap properly. It appears that Firefox is not compensating for the width of the sidebar.

In February this year I started having an issue with reading pdf formatted statements from my bank' (bank and personal information removed). Initially I thought it was some change at the bank so I sent the letter below to my bank.

Further experimenting with Microsoft Edge and Firefox leads me to believe the issue may be with recent changes to firefox. The attached jpg file shows the problem, though not a solution.

I would be curious to know if there is some (new) setting in Firefox to correct the problem.

re: document access on site

You have evidently made some changes in your account display and I have to tell you there are issues with it.

Previously the account document came up as PDF. Today I accessed the current statement and immediately noticed the change in display format.

I usually do two things here. First I print the document. The print button worked as expected. Next I SAVE a copy for future reference. The download button DID NOT WORK.

I had to use the print save to file function. This is where I found the problem. I saw this when I checked my print queue as well. Instead of PDF the document is now PDF.js viewer.

I have to ask why you went to java script when the original PDF format worked properly every time?

On the plus side, my pdf viewer still reads the saved file. It is the unnecessary print to file step to which I object.

I am not at all happy with this change and would encourage you to return to the previous process. Since it was NOT BROKE I am at a lost to understand WHY YOU FIXED IT.

I was really shocked and horrified to see Firefox place the Qatari regime's propaganda mouthpiece on my home screen. The Qatari regime is one of the worlds worst abusers of human rights. It allows no political parties, tolerates no criticism, and severely punishes online dissent. It has absolutely no LGBQ rights, is deeply misogynistic and antisemitic and uses slave labor extensively. Additionally, it is a known supporter of extremism and terrorism. It is not OK to push their propaganda outlet on the front page.

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.

This tab group notification seems to be bugged or something. It just keeps reminding me over and over and over and over.

Any help would be appreciated.

With dailyexpress.co.uk using Firefox there are two pop ups. One is breaking news on each page using right links and the other is a subscribe to read any of the site, which is recent but prevents reading the site. This does not happen using Microsoft Edge.

the clear option on search bar is not working i troubleshoot , restart and even reinstall the Firefox but it is not working . All other options like microphone camera all are working except clear option

I have left Shortcuts toggled on, since I want to see the 18 shortcuts that I have manually pinned. Fine so far.

I have unchecked Sponsored Shortcuts, but I still am seeing sponsored shortcuts added to my dashboard whenever I open a new article. What am I doing wrong?

You say to go to the download page and my version of Windows will be detected & you'll give me the correct version. However, IE 8 in Windows 7 won't go to your download page. So, I need to download from another computer and copy the file to the Windows 7 computer. This doesn't work when you detect that the computer doing the download is a newer computer. How do I tell your system to give me the Windows 7 installer?

"You can turn it off by entering about:config in the URL bar and switching browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false."

That doesn't work anymore. Since the last update, the search went back to the adress bar, doesn't matter if that option is mark as true or false.

Please stop making that the searches go to the adress bar. Nobody likes it.

The above topic doesn't really apply to this. There was no option for this problem.

Now, I use Firefox Relay to mask my email address. It has always been an icon on the toolbar. It has now disappeared. I would like to use it but can't without that icon.

Please help. Thanks.
