Diễn đàn hỗ trợ Firefox

Hello,

I love Mozilla Firefox thus am asking this.

Why is graphics performance worse in Firefox than it is on Microsoft's Edge and Google's Chorme browser?

Is it a matter of settings or what?

I have a AMD Ryzen 5 3400GE APU which is very capable of decoding 4k@60 VP9, but when I try watching Youtube videos in this video settings on Firefox, the frame reproduction isn't smooth. I don't have that problem with Chrome and/or Edge.

The video in question is the following:

PS: not sure why but some 4k@60 VP9 videos on Youtube lag more than others.

Hi,

I need help, on some website's the font has strange symbols.. see the screenshot. how can i fix this? this is pretty annoying.

Thanks in advance.

I've tried to follow all of the suggestions as to fixing why Firefox won't open websites or login - none fixed the issue.

Thanks for any suggestions Dianne

We have a site that for some reason just started getting blocked by FireFox's Tracking content setting in private browsing mode. We have a Production build that still works but our QA build does not. For the life of my I can't figure out what changed that would have triggered Tracking content to start blocking the site. Basically the site will load but we only get a blank page.

Is there any way to debug what exactly the Tracking content filter is blocking?

we have installed Firefox 85.0.2 (esr). we are working in home office with a vpn connection (citrix gateway). the system is set to use proxy settings with a script - every time I start firefox new, it is set to "auto-detect proxy setting for this network" and I have no internet. Also with disabled vpn connection - i have to set the proxy setting to "no proxy" or "use system proxy settings" who sets the setting default to "auto-detect ..."? why is this not working in home-office

Windows did an update and closed my Firefox session. When it came back up, I did not look at it, and it did not restore my previous session. Windows did another update and now when I try to restore the previous session, it just takes me back to a single tab.

How can I restore my previous session? I need those windows desperately!

By running an AntiPwny scan, the only process in the system that shows suspicious activity is FF. So i reinstalled FF with all addons disabled, the only addon i installed on top is LastPass. Ran the scan again, and the same thing happens.

With concerns about supply chain security, I would like the ability to ensure that the file download matches a recognized checksum.

Downloading from: https://www.mozilla.org/en-US/firefox/78.6.1/releasenotes/ yields checksum SHA256 55249C4861FE521CB32D72785481A146B64812AF2ECE7341FAAA5C79ABC0F395

This does not match any of the checksums available at: https://archive.mozilla.org/pub/firefox/releases/78.6.1esr/

Best practice would be to publish the official checksum along with the release notes.

Is there another way to close the loop on this?

When start picture-in-picture mode video starts in same resolution that set in player (for example 720p), but after 1-2 minutes resolution decrease to minimum available at current video(for example 240p). How i can prevent this?

Today, and before, about a year ago, I suddenly got a Firefox screen show up identifying itself as an annual survey. Confetti pouring down the screen.... The incentive was a *chance* to get a prize. So I proceeded cautiously and answered a few questions that seemed legit. Then, I won a prize... A Samsung Galaxy said to be valued at $1100 for $1. I was not on a page at https://easemastereight-15.life/.... Even more cautiously and suspicious moved forward using the click here, and it redirected to a different site, where of course they wanted a credit card to pay for the $1. At this point I bailed, especially because I was offered the same deal a year ago. What I want to do now is to alert Mozilla about this, and after a lot of searching, this form was the only way I could find. If anyone knows how to route this to the people who should investigate this, please do it. Meanwhile we should all remember that if it looks too good to be true, it almost certainly is.

It loads all the tools but the actual planning screen is blank. Used to work trying to see if it's being blocked for security reasons.

Tried refreshing my browser and trouble shooting but no luck.

Hi,

I'm trying to disable the media popup in windows 10, which appears when you lower your volume or skip a song or anything (see added image). I have a brand new pc and on my old pc i was able to fix this easily by doing this: go to about:config and change this: set media.hardwaremediakeys.enabled from true to false.

I did that now, with my new pc as well. But i just does not work, i restarted my browser and pc after changing it, i set it back to true and back to false again, it just will not work.

I googled this issue, but the only solution i find, is what i exactly the thing i described above, nothing else.

Hello, ever since updating Firefox to v85, it's been LOCKING UP every day, sometimes twice a day. Have not been able to figure what site of function is causing the problem.

Have bee watching memory usage in Win Task Manager, Resource Monitor and can see ONE thread of Ffx ramped up to 3 MB.

Firefox updates no longer trusted, will need to do a RESTORE POINT from now on.

Please comment, and where did my first support question go?

Hello, on Ubuntu 20.04, Firefox Browser won't load any websites, or anything. Just nothing shows up.

I did try to uninstall Firefox, and re-install, or re-download from Mozilla repository, nothing changes.

How do I diagnose and resolve this issue?

Thanx,

I recently reinstalled mozilla firefox on my PC and i noticed that in Option>General>Downloads there is no longer the option to disable the "Save File" pop up window whenever u click on a file to download. I searched around, even messed with about:config but i couldn't find a way to disable it. So the question is simple: Is there a way to disable this prompt?

behavior since 86.0 64Bit My website chat opens a second Firefox Window on PM Chat. When sending a message in PM Window the PM Window is going to Background if the same URL is shown in the Main Window. In case the Main Window shows another URL the second Window stays in Foreground. Greets Martin

I had to reset my windows 10 computer and now when I downloaded FireFox I et nothin but a blank page when I open it ? It doesn't matter what website I try it's just a blank page ! I have tried refreshing it and it will not restart but when I click on it to restart it saying that it's already running. Sure enough I open task manager and it's running. If I stop it there it just does the same when restarted. Like ground hog day !
