My MacBook Pro is running OS 11.0.1 and using Firefox 83.0. My battery runs down faster than it used to. Apple suggested checking the Activity monitor and I noticed several instances of FirefoxCP Web Content. I have lots of tabs open. Most of them are using <1% of CPU, but one is about 50%. Is there any way to figure out what that is other than shutting down the tabs one at a time and watching the Activity Monitor?

I've just installed the latest Firefox update (84.0) and now I get the following message where my bookmarks sidebar should be:

The history sidebar works, just not the bookmarks one.

Hi, first of thanks for reading and possibly responding.

The issue I am having has been going on for a few days. In websites where youtube video's are embedded if I try and play the video on the said site it will load and display an error message An error occurred. Please try again later. If I visit the video on youtube, link provided in the video itself, then it plays just fine. Error is not restricted to one site but anything that embeds youtube videos.

I have also come across some strange youtube.com issues, when I am on the main website you get the thumbnails of video's but no time duration are displayed in the thumbnail, neither are the 3 dots where you can have one of the videos removed (not a big deal and maybe this was implemented a while ago I don't know tbh). When I play a video, as in visit the video page on youtube the side bar videos sometimes do and sometimes don't display time duration.

Please check attached image to see what I mean. Left is without said timecodes, right is what it almost should be.

What addons do I use: Ublock Origin is the only one worth noting but even without it the weird thing still occurs. I don't use any plug ins that correspond with youtube.

I am using the latest Firefox on Windows 10.

Things I have tried thus far to resolve it: - make sure Firefox is up to date - try with and without addblocker (Ublock) - remove Adobe flash entirely - refresh Firefox and clear all data and cookies 9tried this I think 3 times now, no change) - looked through older posts with similar issues but most links regarding html5 on youtube were 404 and sometimes the solution stated things like 'cause by some video helped addon' which I do not use or updating Flash

Am I the only one with this issue?

So I've noticed how some video files are able to be played back in Firefox. Some are not able to what so ever, for example I've created a text video using this FFPMEG command: ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 testsrc.mp4

which created the following file: https://astolfo.nl/i/z2ada.mp4 Both the uploaded version and the local .mp4 are unable to be played back in Firefox. However opening them up in edge chromium both files play back perfectly. Besides Edge I've also confirmed it plays back nicely in MPV.

I've tried Hardware acceleration, but both having it on and off did not change the fact that these files wouldn't want to playback in Firefox. Safe mode also did not effect this issue.

Hello! On a certain adult website, all the videos play verrrry slooooly. YouTube videos play fine. And this certain site works fine when I try it with Chrome. I recently added a bunch of adblockers like Ghostery and Adblocker plus and Badger and Decentraleyes and HTPPS Everywhere. Is the problem with one of these? What can I do to get the videos to play at full speed?

Thunderbird 78.5.1 On computer A, probably since one of the latest updates TB is not able anymore to connect to the server, I only get the error message "connection to server xxx failed"

Activity manager shows no messages at all Server xxx is on my network, connection is not blocked TB profile seems to be ok : when using the same profile on computer B, everything is working fine

  • creating new account (same data as existing account) on new profile on computer A is not possible : message "Unable to log in at server. Probably wrong configuration, username or password"
  • however using exactly same procedure and data on computer B, it is working !

So, creating a new account on a new profile is not possible Disabling firewall and AV : no change TB safe mode : no change Reinstalling and uninstalling/installing TB again : no change Windows safe mode with Networking : no change TB config:security.tls settings are identical on computer A and B I changed TB config:security.tls settings : .version.min to 2, 1 and 0 : no change

and .enable_post_handshake_auth to true : no change
and .version.enable-deprecated = true : no change
(all after restarting TB)

Changing TB Server Security settings : no change

I deleted the stored passwords, but after restarting TB is NOT asking for the pw's meaning TB is even NOT trying to connect to the server ?

(error messages are translated from Dutch, so possibly not identical to English ones)

see also https://support.cdn.mozilla.net/en-US/questions/1304493 https://support.mozilla.org/en-US/questions/1269090?page=2 https://support.mozilla.org/nl/questions/1313268

I think I tried almost everything to solve the problem. It seems the problem is on the computer/TB installation, but where ? Can someone tell me how to proceed further ?

Hi, I'm using Firefox 85.0.2(64-bit) Windows 10

While I'm testing local testing for website, whenever I typed/entered localhost OR localhost:8000 Firefox keep redirecting/guesing subdomain for it(which="www"). Made my testing messed up.

There's same issue on https://support.mozilla.org/en-US/questions/1216065 None of those work.

set: browser.fixup.alternate.enabled to false or Connection Settings with No proxy

Please, stop. Chrome and Edge behave normally. This site need darkmode :/

Hi everyone,

Thanks a lot for taking time reading this! :)

I have the following problem with my firefox on Kubuntu 20.04 on my laptop: since a couple of weeks, firefox opens normaly after rebooting, remembered all tabs and my firefox account etc., but it's just not loading anything. I can still type in a web adress or something in the search, I can also still select the drop-down menu on the right ("Open menu") and select e.g. "Settings", but nothing happens afterwords. Same problem for all websites. Some of the main buttons are also not functional (refresh, back/forward). I attached a screenshot from the "empty" firefox (but not sure if that's of any help anyways ;) ).

I tested a couple of things so far, nothing helped:

1) Internet is working, I tested ping, apt is working as well as a differnt browser I installed now).

2) I reinstalled firefox completely by running the following commands:

      sudo apt update
      sudo apt purge firefox // sudo apt --purge autoremove firefox
      sudo rm -rf .mozilla
      reboot
      sudo apt update
      sudo apt install firefox
      (Since I removed the profile folder, the standard tab and bookmarks open/show after starting firefox now, as expeced. I'm also not longer logged in.)

3) By starting firefox via the console, no error messages were shown

4) I created a second ubuntu unser profile, to test if firefox would work there: it doesn't

5) Since I have a dualboot with Win10/Kubuntu 20.04, I started Windows and tested firefox there: it is working as usual.

6) I also obviously tried to google this problem, but either I put the wrong keywords in or this problem is pretty unique/new?

If you need any further information on my system, I'm happy to provide them! Thanks a lot for any recommendations and further ideas, what to do! I'm pretty much desperate for a solution by now, as during home office a not well working system is a pain! ;)

Thanks and stay safe, Katrin

I have run this website (https://www.jeffersonscher.com/sumo/html5-video.html) from previous answers to check and the results are attached to the question.

I have also checked media.eme.enabled and it is set to true.

I am very much puzzled by this.

On new laptop with Windows 10, with an external monitor in extended desktop mode, Firefox is opening partially off screen such that the top bar is inaccessible so I cannot drag it back on screen. If I close it and reopen, it will usually be back on screen. How can I fix this?

Perhaps related: tabs are not reopened and Restore Previous Session does not work.

There are no extensions open.

Thank you for assistance.
