Hi all,

I've been having problems with firefox lagging constantly. General browsing around feels laggy - and opening new tabs pretty much causes my computer to freeze for a few seconds. During this time firefox causes the CPU to spike to 100% usage.

I've been using firefox for years on this computer with no issues. Hardware is pretty good (i7 5820k, 64GB of ram and an SSD).

So far I have tried:

  • Running in safe mode
  • Using a different profile
  • Downgrading to an older firefox
  • Changing allowed CPU cores from 8, to 4
  • Updated graphic card drivers to latest version

None of these work, and I'm getting a bit tired of the constant slow downs. Chrome works flawlessly, as does all my other software...

Any ideas?

Thanks!

Hi,

I had to delete all my profiles and completely reinstall Firefox because Firefox was not changing the color of previous websites to purple no matter what I tried. I thought I could delete the profiles and create a brand new one to start over fresh.

After reinstalling Firefox (latest version) I have run into a problem where under <about:addons> <Plugins> it shows a yellow box and an error saying "Widevine Content Decryption Module provided by Google Inc. will be installed shortly".

This message won't go away and Widevine will not be installed at all. I cannot browse and Netflix, Hulu, HBO Max etc.

I have tried unchecking and checking the <Play DRM-controlled content> under <about:preferences> which does not work.

I have also tried going to this (link)link and manually installing it but the webpage for my OS's .zip file won't load for me.

Yesterday I was using Firefox normally (browsing, Discord, etc.). Today when I opened it, it wouldn't load any page. If I type something in the adress bar it will auto-complete or show suggestions based on google, but when I hit enter, nothing happens. It doesn't even try to load anything. I also can't go into options. When I click on the options button, nothing happens. I am not running in any compatibility modes. I have tried reinstalling Firefox, didn't help. I am not using any add-ons. I have done several virus searches. Other browsers work fine. I'm running out of ideas now, that's why I'm doing this post.

Hi there,

We use GMail/ Calendar/ Drive for our business. On the official account, I am seeing a continuous - multi-day - situation where my Google Drive won't load when I point my browser to it unless I do at least one refresh after getting to Drive and waiting for my list of folders and documents to show up.

In the mean time, the following error shows upon on the bottom left of my screen - "The server encountered an error. Please try again later." - this has persisted for over 2 weeks when I restarted using Fiefox earlier this month. I do not get this error when using Chrome or Safari.

Today, I am also not able to see the user who last modified a document or a folder last, as you can see in the image below.

Please tell me what I can do to fix this issue.

Thanks, Mahesh

Firefox has been awesome. But, my computer just updated to windows 11 and now it doesn't work. Sometimes I try to open the browser and nothing happens (but I somehow end up with something like 7 instances of it running in the background, according to task manager), sometimes I get it to open, but it won't load my homepage or anything, and sometimes it seems to work fine but only for a little while - then it just stops responding.

I have no idea why this is happening or how to fix it. I tried the browser reset, which helped for a little bit but then the problems came back. I think having a theme installed makes it worse, but now I can't even get settings to open so I can try turning it off to see if that helps.

Any ideas? Not being able to use the internet on my computer is a pretty big deal. I'd prefer to not switch browsers, but I don't know what other option I've got at the moment.

Thanks!

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.

This page https://www.nacocanada.com/cpages/common-docs is broken and has a newsletter sign up overlay that can't be closed. So i hide the element with uBlock origin but the underlying page still doesn't scroll. If i make the window taller more content appears, so it is there.

How do I force enable the scroll bar for all websites or at least this one?

In the new version, the Downloads panel automatically opens whenever I save/download a file.

The problem... it STAYS open.

How can I turn it off? I already know where and how to check on my downloaded files. I do not need to see the downloads panel pop up every time I save a file. And I definitely do not need or want it to stay open, causing yet another need for a mouse click to make it go away.

TL/DR: See the image. ;)

I'm on Ubuntu 20.04 (Xubuntu flavor), using Firefox 79.0, working on a web site. I'm coding specifically for Arial... and it's returning Times New Roman.

I have Arial installed, via the ttf-mscorefonts package and also adding them from a Win10 box.

Please, no "But you should do 'font-family: Arial, Veranda, sans-serif'" dismissive answers. Why? Because if I do "font-family: Arial, Veranda" I still get Times New Roman. I can even substitute "Pulsar Beta" here (a font that is installed to my local account) and it still gives me Times New Roman.

If I do "font-family: sans-serif" I get Veranda, not Arial... which is odd because Arial is my default font.

Doing "font-family: Veranda" gets my Times New Roman.

Chrome doesn't have this issue!

As a picture is worth a thousand words, see the pic.

What can I do? I did see some bugs that were fixed in v56, but none of the debugging tips help there.

Hi all

For a while now I've had a problem in Firefox where images randomly show up with green blocky glitches or yellow lines on them. Also sometimes text does not show correctly. I've attached a couple of examples. The image is from my Facebook feed (but it can happen on any website it seems) and the text is open tabs - the one on the right is this page.

Any suggestions? I've refreshed the Firefox install, and have only one add-on - an ad blocker. I've tried two different ad-blocking add-ons and the problem persists with both.

Thanks

I use firefox on Mac OS 10.14.6. Every time I quit firefox (Stopping the program, not simply closing all windows) everything is reset to defaults. For all intents and purposes, it's as though I deleted and re-installed firefox every time I quit out of it. Bookmarks are removed, and any default bookmarks I removed are re-instated. It also opens up the set-up and privacy web pages that it does for the first time when you open it. None of the preference files are locked, it's set to remember history and I'm not permanently in private browsing, it's not even supposed to delete cookies. It's been like this since the moment I installed it; refreshing firefox changes nothing, uninstalling and reinstalling it also changes nothing. The only thing that stays the same is that my computer keeps firefox as my default browser.
