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)

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 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

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?
