Firefox Support Forum

I am using Windows10, Version 20H2 (OS Build 19042.928) with all available patches installed as of 04/14/2021, and am using Firefox 87.0 (64-bit) as the default browser. I have suddenly begun to get the subject error message (Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.) in Firefox, whenever I try to open an email web link from within Thunderbird. Until a few days ago, the email web link always opened up in a new Firefox browser tab.

If I change the default browser to something else, the email web link opens in a new tab in that browser.

I have tried every solution that has been recommended in this support forum to no avail. The error pops up even when Firefox has been started in safe mode. I have created new profiles to no avail. I have even gone so far as to totally uninstall Firefox, then manually rename all of the Firefox directories in my user profile and then install a clean version of Firefox. So far, I have not been able to get rid of the problem.

Any suggestions would be appreciated.

Hello,

I am wondering it this is possible - I have a Windows 10 laptop that needs to be upgraded to V202H and I am told that the upgrade will probably delete all of my current programs and settings - including my Firefox install and all bookmarks. To help recover from that, I wanted to know if it would be possible to set up an alternate Firefox in a not often used local account on my Windows 7 laptop and then sync the two so that after the upgrade, I can download Firefox again onto the Win 10 laptop and then sync it back so that I can get all of my bookmarks and settings for FF back onto the Win 10 laptop.

I don't want to sync it with the Firefox that I use in my regular Win 7 user account since that has a separate set of bookmarks and settings that I wouldn't want to change. I just wanted a way to "hold" all of the Win 10 Firefox stuff and "reinstall" it, and had thought that sync might be a way to do that.

If that won't work, is there a way to transfer the entire FF profile over to a new install on that laptop once it is upgraded?

Thanks for any help! Much appreciated!

Somewhat recently, when editing text in any text field in Firefox (87.0 64 bit), I noticed the arrow keys don't repeat when held down. Other keys do just fine, but the arrow keys, when held down, move one position, there's a very slight delay, and it moves one more position and then stops; no auto-repeating. I've restarted Firefox without addons and that didn't help. I've also toggled the Auto-scrolling and smooth scrolling options too.

This makes editing long text fields a real pain. I don't see this problem in any PC-based apps and arrows keys do repeat OK in Chrome and Edge. It appears to be a Firefox issue.

Any ideas? Many thanks!!!!!

Hi Firefox guys, I've recently created a windows domain (2019 servers only, clients and dc) and deployed firefox 87 On all computers.. Now I need to make sure firefox uses the best practice ciphers only.

• • Is there a way of customizing such security setting, across the network? maybe using GPO**?

(I am having a hard time trying to find relevant info, no luck yet)

Thanks in advance :)

I have noticed a recently developing event in Firefox. When scrolling through some pages such as LinkedIn or Facebook, my screen will suddenly go completely white. It seems to freeze for a second or two, then comes back. This has only been happening for about the past two or three weeks, so since about 1 April 2021 for time reference. My About Firefox shows I am running 87.0 (64-bit) and it is up to date. I completely uninstalled - including the deletion of the Mozilla folders per info on the web - then reinstalled. This did not correct the issue. I also run Chrome and do not experience this issue when using it.

Hi!

I find the status text mostly annoying, but the URL usually useful. So instead of hiding the whole thing I only want to get rid of the status information.

Hi,

I was trying to use firefox primary password without knowing what it does :(. Well by the time i set the primary password in firefox i realise that it replaced all the saved login passwords of over 600 URLS with primary password.

I checked few articles where they have spoken about replacing logins-backup.json and key4.db file. In my case though i think this will not help because i had my syncing on, when i did primary password setting change. is there any method with which i can restore my previous passwords by creating new profile may be.

Just desperately need way with which i can restore the passwords else this will be really difficult for my work

Thanks Prasad

There is a thin border around the Firefox browser when it is not in full screen mode.

It disappears in full screen mode.

Is there a way to remove this border without having to use the browser in full screen?

Pictures attached.

I have used firefox for many years. I very often use CTRL+F to search on webpages. Now it just does not work on one website i use very often. It seems to work on all websites but not this one. Does anyone have a clue ?

Here is the website it doesn't work on. Its a website that publishes Icelandic laws.

Pagination cannot be moved with the mouse And opening a page with the middle button will automatically jump to the new page. How to use the original fan page to move it with the mouse, and the middle button to open the page will first be in the original page

Suddenly my right click mouse button doesn't work with dropdown boxes (so for example above when I needed to select the topic I had to use my arrow key) .The choices, or different logins pop up for a second but I can't select one. This happened suddenly last week. Only in firefox and it's pretty annoying. What has been changed? thanks

All of a sudden when I hit the ctrl key my screen starts zooming in like mad. this is without pressing + or minus or touching my mouse. Means I'm not longer able to use control C or Control V for copy and paste, and it's driving me mad. Any help?

I have entered the website i wish to use and logged in all goes well until i try to open my webcam and go live. i have a webcam its always worked but its now saying to me Chat server authentication failed please contact us. Im confused it always worked

Since a few months, I have noticed a nasty issue with pasting on some websites.

For example, when I try to paste text in the body with CTRL/CMD+V on the web interface of my email provider (mailbox.org), the cursor is moved to the end of the message but no text is copied. Right-click > paste does work, and no issue for the recipient and subject fields. The issue is only when writing emails in HTML; plain text works fine. Another example, when editing a protocol on protocols.io, hitting CTRL/CMD+V leads to a blank page, which needs to be refreshed (but the text has not been pasted). There is no option to do it via right-click > paste there. Same issue when submitting a manuscript on PCI Paleontology.

All these examples are specific to Firefox (I have the latest version installed); it is reproducible both on macOS 10.15 and Win10. It doesn't seem to be due to add-ons (I tried to deactivate them one by one and nothing changed). There is no problem with Chrome-based browsers (e.g. Iridium) or Safari.

Is it maybe some configuration or something? Any idea?
