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,

When I go to Facebook on Mozilla and try to use the messenger app to run a video call (using microsoft surface running windows 10), the default camera is my rear facing camera. There is no toggle i can see to switch it to the front camera. I cannot do so in window settings and have spoken with Microsoft support which tells me to call mozilla support. I cannot do it in any of the facebook settings either. I cannot do it with camera settings in mozilla either. I can use the front camera successfully from chrome! I can from Edge! I can from Zoom. I like mozilla and want to keep using it but if I can't resolve this I will likely just switch to chrome permanently. Please let me know how to select the default camera in mozilla. Thank you.

I had accidentally refreshed my Firefox, and after adding back all my old data, I found that the pocket stories were missing form my new tab. I manged to fix this issue, but when I go into new tab settings to make it show more than 3 stories, there are no options for them. It just gives me options for search, top sites, highlights, and snippets. How do I get these settings back?

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

To start off, I've never used the sync feature. Not that I think it won't work, I just haven't trusted the cloud enough yet. That being said, I know my logins and passwords are stored in the "profile" in the appdata of mozilla firefox, on this local computer. To my knowledge, this information is stored in the "logins.json" file located in my default profile. Up until now, I have had no issues retrieving the information I need. However, after this morning, when Version 81 was installed, I visited a website where I needed a particular login. I normally have Firefox automatically populate this information, on this particular site. However, since that did not happen this time, I checked my "logins and passwords" page, only to find "No logins found" on the sidebar, and "No synced logins found" in the main space, with instructions on how to sync from other devices or import from other browsers. Since I have not had a login before (for Firefox), I created an account to see if I could import the information from a previous version. However, only other browsers were listed, and I can't sync from another device, as the information is stored on this machine. Creating an account has also allowed me to post here...

I have opened the logins.json file with notepad, and the logins-backup.json file, and both are full of information. Of course it's not plain text, but the information is there. I can also open these files with Firefox, however, it doesn't recognize the file as the "logins and passwords" file, it just displays the encrypted information in a different (html?) format.

Any advice on how I can import these 55+ logins and passwords without re-creating or changing each one of them? Thanks.

Starting this morning I'm getting a weird error message when I try to share articles from things like Daily KOS from my email. This is the message: "App Not Setup: This app is still in development mode, and you don't have access to it. Switch to a registered test user or ask an app admin for permissions."

  I have no idea what that means and I don't see any references to it in the community answers. Suggestions?

Thanks.

Hello, I just upgraded from version 80.1 to version 81 on my Win7 system. I was looking forward to using the new PDF form filling feature but when I open a PDF document containing forms and try to enter data into a field, I get the following message:

This PDF file contains forms. The filling of form fields is not supported.

Do I need to configure something to allow Firefox to fill fields in a PDF form document?

The What's New page says this feature is available in version 81 and higher but does not say how to enable it. Thanks

I used to be able to print any web page/document by pressing "CTRL + P" and then pressing "ENTER". I print about 40-50 documents a day at work. Firefox decided to make an update where the "Print" button is no longer selected by default, so pressing ENTER doesn't do anything. You have to manually drag the mouse down and click it. Does anyone know a hotkey to print without using the mouse?

I know it sounds silly, but dragging the mouse 50 times a day to the print button when it used to be instant is making me want to switch to Chrome again, since they're pretty much the same thing now.

pressing Ctrl+F doesn't open the "find in this page" toolbar, on any page.

  • doesn't work in safemode, either
  • DOES work when selecting from the "Edit" menu (where it shows the shortcut as being ctrl+f)
  • I read online that Ctrl+G might work? this one has mixed results for me... I think it's working like F3, repeating the previous search, if there is one, and if it has any matches, and only if neither of those are true, opens the "find in this page" toolbar
  • pressing "/" and apostrophe both do their things (but not when an input/textarea has focus, of course)

Last night, I noticed that the usual Dock icon for Firefox developer Edition had changed from Blue Fox to what looked like the App Store brush/pencil triangle. I restarted but it persisted. Removed the application and re-downloaded and re-installed, but same issue. I then noticed that all the Tools -> Web Developer tools had gone from the menu. Likewise, doing Firefox -> About inserted 'about:preferences' in the search bar, but nothing else happened. Tried launching the settings from the right side hamburger menu, again nothing happened.

Read around a bit, and deleted one of two profiles from ~/Library/ApplicationSupport/..., then tried re-install and restart the Developer Edition, but that complained that a profile was missing. Restored the profile I deleted, but same problem as before.

I'm stumped. Can anyone help with this one please? I'm on Mac, latest version of Mojave.

Thanks

As a researcher and writer I'm constantly on the web, and have many downloaded book marks that were organized by folders on the Menu bar. But this old laptop seems to crash frequently when I'm using Firefox. After the most recent crash most of the folders had vanished - three did not.

How can I restore those missing folders to the menu bar? Redoing them is a possibility, but would take a great deal of time.

Thanks,

DMS
