Firefox supportforum

Sometimes all add-ons / extensions break randomly and are disabled (the icon of the extensions is also broken under "Manage Your Extensions").

The extensions are visible under "about:addons", but the slider is turned off and the icon in front of each extension is broken / empty.

It seems that deleting these 2 files- compatibility.ini and extensions.json inside the firefox profile folder, usually fixes the issue. Only these 2 files though, don't delete anything else.

No need to mess around with the ff profiles or anything else, just deleting those 2 files and restarting the firefox usually fixes the issue with the "unregistered" addons.

This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.

I wonder what causes the extensions to "unregister" randomly.

I am receiving this error message when I try to log into my router. My router has a certificate from Let's Encrypt.

What settings do I have wrong?

Regards.

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.

Enivronment: OS: Windows 10 professional 22H2 Firefox version: "124.0.2 (64 位)", auto update is enabled, it should be the newest version. security software: windows defender

The page https://www.stardock.com/products/groupy/update opens during the loading of the OS background processes. I have looked up on the windows task manager, the about:config and haven't found anything related to this process.

I use Outlook.live.com Hotmail and recently a PopUp Message appears asking me to:

Add outlook.live.com as an application for mailto links.

Microsoft Customer Service said it was not something they initiated and likely a Firefox issue.

It does not seem safe to click on a random link like this without any explanation. Each time I log in, the same message appears.

Could someone please explain what this is for and how I can stop it from popping up each time I log into Hotmail?

After signing into an account with Schwab.com, the site has a "Launch" button that opens the Schwab "Streetsmart Edge" trading platform. However, after signing into Schwab.com with the Firefox browser, clicking on the "Streetsmart Edge" Launch button does not work. "Streetsmart Edge" does not open.

This problem only occurs when using Firefox. If using Microsoft's browser there is no problem.

Previously, until about two month ago, the Firefox browser never caused this problem. It worked fine for many years.

I prefer the Firefox browser versus Microsoft. Please research and repair this issue.

In windows 10, unrepeatably, firefox won't open google so I immediately open it in a new tab and it works. This happens randomly so I can't do any tests to find out if it is an extension or hardware acceleration that is the problem.

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

For one site I go to there is an internal menu where I should be able to scroll down. In Firefox, there is no option on the right side for me to scroll down...but in Chrome I have no problem. The owner of the website said it should work in Firefox but it's not. I have attached images from the 2 browsers. I have attached 2 screenshots. For Chrome you can see to the right of the numbers under the Acct # column that I can scroll down. But in Firefox I don't have that option to scroll down to see entries at the bottom of the list.

Help! How can I fix this so I can scroll down in Firefox for this sub-menu item?

Thanks, Steve

Hey Gang -- Has anyone else experienced this?

Whenever I'm on NPR's website listening to a radio program, I can't access any other websites on separate tabs or windows. (they simply won't 'load' or even acknowledge any commands)

I find this to be very strange.

If anyone can help with this minor quandary I would be grateful.

Sincerely,

PS - I am using a PC desktop computer, running Windows 10 and using the latest Firefox version 124.0.2

Hi I am a longtime user of your browser. I have version 124.0.2(64 bit) installed on three devices. First thing I do on opening it is to click on "about", which normally updates the browser, before I do any browsing. In the last three weeks, however, it has not updated on any of the three devices, rather, it says "Failed to check for updates". I have tried the workarounds suggested at your Help center, and nothing has worked. What gives, may I ask? Thank you
