I have tried everything I can think of and everything I have been told on how to fix this. I finally went back to Safari.

Firefox 79.0 (64bit).

I sat today and watched Firefox with ActivityMonitor running and would go from website to website seeing how often Firefox would freeze the entire mac up. I thought it was just the mouse that was being frozen, nope, it is the entire mac. Everything stops when this freeze occurs. Today I experienced the longest freezes. One lasted over 20 seconds.

I will keep my eye on updates to see if this problem gets fixed. Until then, back to Safari :-(

I have used Firefox on my Mac (Catalina 10.15.6) for 3 years. Yesterday I got a message: 'The application “Firefox.app” can’t be opened.' Since then I have repeatedly deleted Firefox and all it's associated files; downloaded ver 79 and the results have been the same. So I went to Beta ver 80 and got the same results. As a user of Firefox since it was introduced as Mozilla, I find everything else unsatisfactory and hope someone can help

I'm trying to switch from opera to Firefox, as title says, Firefox is slow when live commenting is enabled on bilibili.com when watching videos, it gets worse if you play video in full-screen mode, and CPU is about 15% higher than opera even not in full-screen.

I've tested on other two similar website: douyu.com and huya.com , turns out the issue is only with bilibili.com, I found that the live comment feature is implemented by canvas on bilibili.com while the other two sites uses css3 instead, and I simply tested canvas benchmark with benchmark1 and benchmark2 and the result conforms my guess -- opera performs much better than Firefox.

I've tried toggle hardware acceleration and safe mode, no significant improvement observed

Hi

I want to be able to stop autofill for a single website but keep it on for everything else.

I run a website that means I have to input a lot of data into boxes and Firefox annoyingly wants to auto fill every box meaning the data gets messed up from time to time.

Is there anyway to disable it for single sites?

Thanks

I can start a youtube video but the mouse will not click on "skip ads" or pause the video or move the video to different times within the video. The same thing happens on other sites, for example I can click on walmart.com and then all other clicks will not function cannot proceed any further within the site. I have uninstalled/reinstalled firefox, I have tried safe mode and I have disabled all add ons. I use the default theme and nothing works. This was not an issue prior to the most recent update. The only way for me to post this is via Edge and edge is crappy.

Whenever I visit any website to play music or watch videos no sound is provided. I can visit the same sites using Chrome and the all play sound. I can play music that resides on my PC without any issues. I have re-installed Firefox but to no avail - still no sound. My sound settings are not muted either in Windows, when on the various sites and within Firefox itself. I have Autoplay permissions set to allow video and audio. I am using 79.0 (64 bit) What is the problem and how do I resolve it?

In the last few days, a process called MainThread, using a lot of CPU time, has started appearing in my Ubuntu system monitor "top". I was worried that it was malware, and checked to see if it might be part of software I had recently installed. After checking with the software providers I had most recently dealt with, I didn't find any that said the MainThread process belonged to them. Then I noticed that the "firefox" process had disappeared from the system monitor. I suspect that MainThread is the new name for firefox, but I would like some confirmation of that theory. If that is the case, why change the name of the process from something recognizable to something unrecognizable? Thanks for any help you can give!

Recently switched over from Chrome and I'm liking it so far with one semi-major annoyance.

If I'm watching a YouTube (or any site) video in full screen mode, I don't see any of my Mac notifications until I exit full screen. With Chrome, those notifications continue to appear while I'm in full screen.

Is there any setting in Firefox I can enable or disable to change that behavior?

Hi Firefox Community!

Earlier today, I updated to the latest version of Firefox (79.0). Now, everything I saved in Pocket (my entire list) is gone. Also, when I clicked on "View Pocket List", I was prompted - for the first time ever - to sign in to access it.

I'm very confused, and upset, as I had a number of web pages and articles that were very important to me.

If anyone can help, I would be truly grateful.

Thanks, Lynda

ПОМОГИТЕ Произошла проблема с переключением мультимедии,. Решил перейти с браузера Chrome на Firefox, и столкнулся следующей проблемой: Я не могу переключать музыку и видео с помощью горячих клавиш на клавиатуре, таких как F12,F11,F9, данные клавиши у меня использовались как макрос на наушниках и я в любой момент и в любом приложении, мог переключить музыку, которая играла в браузере через наушники, что было очень удобно ( также можно было и ставить на паузу видео). И вот сейчас я всё сделал и перенёс все данные, но найти решение данной проблемы не могу, тк это окошко с мультимедией просто не открывается и не работает

The problem is spotting the start of a logical grouping in many tabs open at once in a window. I arrange them in order when researching something. So, there's 20 tabs open, 4 different categories of the subject topic. There has to be a way besides a sidebar, to signify fast which group starts where. Best case scenario would be marking the 1st tab of a group with a flag, or static pop-up - a short, 15 character-limit description to signify which group it is (like '4k', '1080p', '720p', for video resolution values). 2nd-best would be a mouse-hover message, i.e. a flag or balloon to pop-up with the 15-character description. Finally, I could color-code the 1st tab of a group, or even the text .I saw some good extensions that did these - looks like Firefox disabled them with the latest browser upgrade. Are there any cross-browser or Firefox persistent apps or add-ons that will let me mark up individual tabs, with either icons, messages, or background colors?

menubar no longer shows in a new window opened with window.open? I am running Firefox Ver. 79.0 (64-bit); Mozilla Firefox for Ubuntu canonical - 1.0; on Ubuntu Bionic 18.04 I use the following javascript code in <head> to open a new window: <script> </script> The body is as follows: <body bgcolor="#F2E8DE" onLoad="nameThisWindow()">

Click <a href="javascript:openHomePage()">Open Homepage</a> to open Homepage.htm in a new Window. </body> This code will not display the menubar in the new window (HomePage). The new window opens, resizes, relocates, has scrollbars, has address bar and has the [Open menu] option to the right of the address bar. The way it should except for the menubar on my desktop computer. If I right click on [Open Menu] in the new window it shows a check mark before Menu Bar. If I uncheck it, it closes the menubar in the window that opened it (HomePageCaller). If I click on Customize in HomePage, it opens the customize window in a new Tab in HomePageCaller. If I open a link in HomePage with "Open Link in New Tab" it opens the link in HomePageCaller. If I open a link in HomePage with "Open Link in New Window" it opens the new window with a menubar like it should. I have opened about:config to change all nine of the "dom.disable_window_open" options to "false" and restarted the computer. This did not change anything? I have removed all content from the<head> except the <title> in the new window page. I have removed all content from the <body> except a line that says it is the new window. All to no avail. Thank you for any help someone can provide, Rob
