Firefox causes 100% CPU usage when opening couple tabs at the same time!!!

I Am on desktop:

i5 9600KF (high performance mode) 16GB 3200mhz ram NVME... Windows 10 Pro x64 Firefox last stable

When I open Firefox tabs aren't loaded all at the same time, but they are suspended. So after that: when I switch between 6 tabs quickly - they start to open at the same time. And CPU usage skyrockets to 100% LOL! Given I Am on high end PC - this is joke! I was using chrome and had hundreds of tabs and Chrome doesn't even suspend them by default. They open all at the same time I think!

So there is something wrong! I tried troubleshooting mode and it was the same problem!

Thanks for help!

Help please! I'm not tech savvy and I accidentally deleted my Firefox profile.

I was trying to fix my Firefox high CPU issue and followed the advice below. I didn't realize deleting my profile would mean losing everything. Is there a way to restore my old profile? I didn't delete the files from my old profile.

I would greatly appreciate any advice to help fix this. I'm on Windows 10 Pro. Thank you!

"Run" command: firefox.exe -P I deleted my only profile “default” I choose “Don’t delete files” Then I created a new profile

Hi!

I want to change the default serif and monospace fonts (Atkinson Hyperlegible and Hack, respectively) in Firefox. However, the fonts that are listed in the advanced font settings appear to be a specific list that doesn't update with the system-installed fonts, so I cannot pick the previously mentioned fonts. I tried working around by tweaking with the about:config values, but so far no luck. Any advice?

Thanks in advance, Lucas

FF 93.0 64-bit - Windows 10

When I booted up the system and ran FF the first time for the day, its window opened, and it even asked for the primary password. After that, nothing I typed in the URL box came out. I could open new tabs but not able to switch to them. All Chromium-based browsers and Edge in the same system worked fine.

I did the following trying to fix the problem: I restarted Win10 and ran FF93. Same problem. I restarted using Troubleshooting Mode. Same problem. I reinstalled using the complete package. Same problem. I installed using FF92 and FF91. Same problem. I refreshed FF93 using Troubleshooting Mode. Same problem. I used Win10 Safe Mode to run FF93. It worked. I uninstalled FF93, removed as much as I could all traces of FF and Mozilla in the Win registry, and reinstalled FF93. Same problem.

In the end, I had to use Win10 Recovery and revert to an earlier date to fix it.

The first incident happened about two weeks ago. It happened again this morning. My use of PC has been routine for years, I would say for more than a decade, or at least in the last five years. No extraordinary applications or routines.

BTW, I haven't updated my Win10 in years, because doing so often times gave me new mysterious issues to troubleshoot, courtesy of MS. You should very well know Win updates produce issues, and the bug fixes following them produce even more. The annoying thing is I would research on the issues and find out later (sometimes days) that the updates were the culprits.

This is the second time it happened to my FF93, and I feel I have to report this to get some idea about why this is happening (only to me?) and how to fix or prevent it without having to go into Recovery (again?).

How do I stop all installed firefox extensions from loading their main page after syncing?

every time I sync from a different computer or version of windows all the extensions load up their main author page all at the same time overtaking my browsing session so that I have to manually close each tab

its very frustrating On a side note Also after unnecessarily refreshing firefox and before manually changing proxy settings to "no proxy" after each refresh (Why is no proxy not the default setting anymore?) why was every webpage blocked and needing a security certificate? even google.com? and not long ago firefox crashed every tab, constantly, it wasnt even usuable but Im so dependant on its features I tolerated it but cant afford to much longer I have to use Chrome for my business as firefox doesnt always capture login/password for autologin nor for address, etc -fill in

I had to put in a new hard-drive into my computer that I previously was running Firefox browser on so I downloaded the Firefox back on after the new hard-drive was done. Before on my old hard-drive when I click Firefox browser and it came on, it had a ribbon across the top of the screen underneath the back arrow, forward arrow, and search URL that I used the most of in my favorites (I think it showed across the screen about 10 of my bookmarks) to click on instead of going into all my bookmarks to get. How can I put my most used bookmarks across the top of screen now instead of just clicking the "star" that show ALL my bookmarks and I have to go down to whichever one I want to use and boy do I have a bunch of bookmarks even thou they are in alphabet order? I hope someone can tell me how to do this!

YouTube TV Buffering Problem with Firefox

I have hit what appears to be a "YouTube TV" (vs YouTube) buffering problem. It happens only with Firefox on my PCs. After a few seconds to a minute of playing a TV program or movie, the video/audio stops with a spinning arrow. If I previously had turned on "stats for nerds" to monitor this, I can see when network activity stops and the buffer then eventually gets exhausted.

This does NOT happen when running YouTube TV on my TVs or on my iPhone. Probably more significant, it does NOT happen with YouTube TV under either Microsoft Edge or Google Chrome on these PCs. If I run Firefox in Troubleshoot Mode, i.e., no add-ons, extensions, etc., the problem still exists, so it is not just some rogue add-on, but is related to Firefox itself. The problem appears to be only for "YouTube TV" on Firefox since, for example, videos played from YouTube (vs "YouTube TV") do not have the problem under Firefox.

I tried rebooting my router as well as the PCs. The problem still existed. The PCs are high speed and the internet connection is fiber optic. One of the PCs is connected by Ethernet; the other is wireless. Download/upload speeds are over 900 Mbps on the Ethernet PC. I have not seen slow network indications on anything except this "YouTube TV" with Firefox mixture. Hardware does not seem to be the issue.

Apparently the problem is software. I also tried temporarily disabling my antivirus/firewall software. No change. I'm running Windows 10 version 21H1 and Firefox 88.0.1. I'm new to YouTube TV; although most of my viewing with it has been done on TVs, I don't recall seeing this problem in my PC tests a month or so ago.

I lost all the bookmarks suddenly where i was using this browser for office work, there was no action taken from my end like deletion or any upgrade, however suddenly when i start machine today, i found all bookmarks lost. To restore backup I entered to Profile --> bookmark backup this file is extension JSONLZ4 which is not visible during restore bookmark.

This is quite important to recover these suddenly lost all bookmarks, so is there any way or support available?

Unfortunately this is first time i am facing such kind of issue, So kindly also let me know if we should trust mozilla firefox as default browser and to save bookmarks?

Thanks & Regards

I turned my computer on today and all of a sudden half of the file icons on my desktop now have a Firefox file logo and I want my desktop to be restored to its original appearance. I did nothing to cause this and do not appreciate the Firefox browser software changing the appearance of my desktop without my permission. Also I do not like having to take the time correcting the situation. Do I need to delete Firefox from my computer and start using a different browser? Can you direct me as to how best to fix this???

I am running "Firefox Browser 93.0", and I have Windows 10 Pro Version 21H1, OS Build 19043.1288. I am unable to watch certain video's, as an example, the video in this link: [https://www.wandtv.com/news/illinois-.../article_24b92a86-32c4-11ec-a487-3bb3f17fa133.html] won't play. It use to work, but something has changed, not by me. It will play that same video using the "Edge Browser" so there is nothing wrong with the website. However, I can play this "YouTube Video": [https://www.youtube.com/watch?v=qAJSYk5wMiA] I also tried another link in their website, this is the weather link: [https://www.wandtv.com/weather] it starts to play, but then stops and nothing ever plays. Here is another link I tried on their website: [https://www.wandtv.com/sports/fans-ma.../article_f94f4ade-32e0-11ec-9351-ef71f52b96cd.html] It won't play either. But they all play in the "Edge Browser!" Any ideas on what changed and how do I change it back, so they will play? I prefer Firefox Browser to any other browser! Do you know what the issue could be? I appreciate your time! NiceSeeingYou

Hello! Something in my Firefox installation seems to be making several Google network (google.com / forcesafesearch.google.com / www.youtube-nocookie.com / m.youtube.com, and a couple of others) calls shortly after launch. I have a DNS sinkhole, so that is how I can see.

I have a few reputable extensions (or should be, from EFF, Firefox itself, or Ublock Origin), but it also happens in safe mode. I went through a good chunk of this: https://support.mozilla.org/en-US/kb/how-stop-firefox-making-automatic-connections and still the calls occur

I am on Windows 10, with FF v93.

Thanks very much!

I am using a Cambio W101 tablet with windows 10 21H1 and Firefox 93.0.

After getting the BSOD with the error message DRIVER POWER STATE FAILURE I followed the recommended suggestions like checking the drivers, removing the sleep mode, changing the power options.

I continue to get the BSOD only in one specific situation but frequently. It is when I use Libreoffice as my active window, while Firefox is inactive in the background. When I use either only Libreoffice or only Firefox as my active window nothing happens. There has also not been problems with other programs.

Does an inactive Firefox do something which triggers the BSOD?
