I'm using Firefox v 83.0 on Manjaro (Gnome) Linux. YouTube videos in theater/full-screen mode lag if resolution is higher than 360p and cause the CPU usage to burst. This happens for large web pages as well: when I scroll the page, text overlaps and everything is terribly slow. I've checked and this seems to be a Firefox related problem; videos play smoothly both on VLC and Chromium. I've tried all official troubleshooting suggestions: changing to default theme, refreshing Firefox, starting in safe-mode, disabling extensions, disabling hardware acceleration and so on, with no success. I've never had any problems with Firefox for Linux before and I wonder what could be the cause.

I attached screenshots for comparison of CPU usage for the same video playing in theater mode in Firefox and Chromium.

Hi, my Firefox Menu bar always randomly stops responding... the "Apple" Menu & the "Firefox" Menu (About, Prefs., Hide/Show, Quit both still work, but not the rest of the Firefox menus (File, Edit, View, History, Bookmarks, Tools, Window, Help)... those randomly become unresponsive, then total stop when using Firefox...)

Is there a setting in Firefox, or is there a way using Apple's Activity Monitor, or a Terminal command to force a restart of the Menu bars? this is getting very annoying LOL

Hi everyone,

I have this message that appears on every web page but my connection is fine: "you must log in to this network before you can access the internet". It appeared I don't know how (maybe after using my VPN?) and I can't get rid of it. Any idea?

In advance, thanks a lot.

The issue: on all sites, whenever media with audio plays (either automatically, or when I click), the audio stops after 2-3 seconds. If it is video, the video continues to play without sound. When it is audio-only, such as bandcamp, the timestamp stops. Audio resumes playing if I rewind or manually move the timestamp handle (scrubber?) back. This must be repeated each time the media is paused. Audio does not resume playing if play and pause are pressed, or if the site is refreshed.

Troubleshooting steps attempted so far:

  • Tried a different browser. Microsoft Edge works just fine.
  • Allowed autoplay for both audio and video
  • Cleared cache, and ensured that cookies were allowed
  • Turned off all adblockers
  • Uninstalled flash
  • Refreshed firefox settings

I'm at a loss!

When I open articles or posts on yahoo.com, Firefox will not allow the twitter or other links to be viewed on the page. I have tried with add-ons disabled and in Private mode. These can be viewed in other browsers without a problem.

Do I need to turn a feature on or off?

Guten Abend, ich habe ein Problem beim FireFox-Browser auf einem Amazon Tablett. Es wäre schön, wenn Sie mir Hinweise zur Fehlerbeseitigung geben könnten. Danke. Meine Frau und ich nutzen seit ca. 2 Jahren das oben genannte Tablett 'fire HD 10' von Amazon. Auf dem Tablett haben wir die FireFox App installiert. Sie funktionierte bis gestern ohne Probleme. Als wir das Tablet heute Abend wieder mit FireFox benutzen wollten bekamen wir die Absturz-Anzeige (wie im Bild). Als Erste Massnahme habe ich den Cash der FireFox App gelöscht. Dann das Tablett nach aktueller Software suchen lassen und die Software des Amazone-Tablett anschlissend aktualisiert. Der Fehler blieb. Abschließend habe ich dann noch die FireFox App deinstalliert sowie aktuell aus dem PlayStore von Google runter geladen und installiert. Allerdings bleibt der Fehler weiterhin bestehen.

Good evening, I have a problem with the FireFox browser on an Amazon tablet. It would be nice if you could give me some troubleshooting tips. Thank you. My wife and I have been using the above mentioned tablet fire HD 10 from Amazon for about 2 years. We installed the FireFox app on the tablet. It worked without any problems until yesterday. When we wanted to use the tablet with FireFox again this evening, we got the crash display (as in the picture). As a first measure, I deleted the FireFox app's cash. Then let the tablet search for the latest software and then update the software of the Amazone tablet. The mistake remained. Finally, I uninstalled the FireFox app and downloaded it from the Google PlayStore and installed it. However, the error persists.

Been watching streams for a while. Twitch.TV works perfectly well, Piczel.TV is alright too. I do however have constant issues with any kind of live stream when using Picarto.TV- It seems like the stream just doesn't want to load for long- it will work for a little but and then start an endless buffering cycle which can only be broken by refreshing the entire website, rinse and repeat. I tried cleaning my cookies once which didn't help. Using Firefox's installer to run a "fix" didn't help either, and a fresh install *did* work, but only for a little bit before it started happening again. The option in Picarto to switch the HLS player tech to mp4 doesn't work. Any advice?

Have tried just about everything (i think) as i have read in the other support posts. When i boot my computer and try firefox, it loads for a second and then crashes asking to send the crash report and to restore the tab. I click yes and it crashes again with the same window. Sometimes if i reboot it all of a sudden works. But literally everyday when i log on for the first time it crashes, then i reboot and sometimes it crashes, and then sometimes on the second reboot it just works somehow. I have tried installing earlier versions, refreshing firefox, starting in safe mode etc.

Here are a few of the crash IDs that were submitted successfully (others failed to submit). Thanks for your help.

Hi, I recently updated to FF 83.0 and if I open Youtube then play a video my RAM usage sits around 900mb.

If I minimize Firefox or open a new tab, the tab with YouTube playing will start climbing in RAM usage. It will go up to 7.5 GB RAM used and it won't free it up.

I downgraded to FF 82.0.2 and it goes away with same addons. It will sit around the 900mb in this version like it always used to. This only started with the release of FF 83.0

I want to use the new FF version for security, but not being able to play any YouTube videos is bad.

Any help would be greatly appreciated!

Since I installed Firefox 82 (on Mac OS 10.14) when I'm filling in an online form FF jumps away from the page and brings up an error message telling me that the form is no longer available. Huh? I can use the "Try again" button and it takes me back to the form, but might have lost some of my entries. This happened several times when I was entering data for a bank transfer and has just happened again when I was ordering something online. I've now installed FF 83 but have the same problem. I use only 2 extensions: 1 Password and Privacy Pass. Thank you in anticipation of helping me sort this out.
