How can I resolve the failure to open because it can't find the XPCOM. I downloaded a new copy but the computer insists on using the older, faulty version to open files and it will not work.

A new Facebook link can open Firefox and work, but subsequent Facebook links result in a failure. The error message is "This content isn't available right now When this happens, it's usually because the owner only shared it with a small group of people, changed who can see it or it's been deleted."

The Facebook links work with other browsers.

Restarting Firefox begins the cycle again. This has become a problem just in the last month or so.

Hi, I am getting a message about Java being blocked it may be being blocked and it is happening often. I need to be able to turn off what is doing this. So I can see what is on the sites I am trying to use. Thanks Dave

Hey everyone!

I just noticed that post FF's 150 update, I can no longer drag and drop folders into my DSM window. This has been a non issue for over 6 years and all of a sudden, poof. I did find that you can still to this on Safari, but long term, Mozilla and Synology need to address this. There's already a post on the Synology fourms about it and I've emailed their Support Team to see what they have to day. Posting this here in case anyone has found a workaround in the Config settings pane.

Thanks! --Brian

Hey there since a week when I brows with Firefox on Windows desktop the RAM uses jumped from around 60% spiked to 92-95% RAM and that changed just come a long a week ago. If change brows like Chrome different story, back down at 65. So you can also see a massive number on Firefox system running.

I am trying to access static IP addresses on my Intranet. I could in the past type in the IP address and I would get a notice that the site is not secure and allow me to continue to the site. Now it tells me that the website cannot be reached. I need to get to the GUI interface of cameras on my network. How do I get this to work?

The VPN works if I Enable DNS over HTTPS using Default Protection, however if I select Max Protection and use Cloudflare, it does not work as it cannot resolve DNS.

If I disable the VPN or select Defualt Protection, DNS works again.

Hi All,

I have tried the new free browser VPN however it does not load pages if I am using a custom DNS (Quad9) and have DNS over HTTPS enabled. Is this expected behaviour and just a limitation of the VPN?

Any advice would be much appreciated.

My anitvirus software is blocking a website that I use. Its legitimate. How can I unblock it?

I am attempting to use Firefox's new built-in VPN to hide my browsing and use sites that are restricted like Reddit on a common wifi while I am on breaks. It worked on these common wifi systems for a little bit, but last week I believe, it just stopped working one day. Now, when I turn on the VPN, the only thing Firefox will do is display the following error: ~~~~~ Unable to find the proxy server

Firefox can’t connect to the server at [insert url here] What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi. ~~~~~ I was originally running Firefox 149 via snap on Ubuntu, but I just uninstalled the snap package and switched to 150.0.1 via the Mozilla APT repository and I am getting identical behavior. Is this just a bug, or is it possible the administrator here has explicitly blocked Firefox VPN? Is there anything else I can do about it, since connecting on a different device doesn't help me, I can't check the modem or router, and disconnecting and reconnecting does nothing?

Using a Mac Monterey 12.7.6 and uptodate firefox.

Trying to use "tree style tabs". I'm trying to drag and drop a tab named "CHILD" to a tab named "PARENT". Instead of appearing in the tab PARENT the CHILD tab disappears and its content is added to the PARENT tab.

I would prefer the child tab to nest within the parent tab.

Thank you!

Hello. I have a question regarding a problem with exporting files in Firefox. For about four days now, when I try to export files in Firefox, it fails. I've looked into it, but haven't been able to find a solution. Could you please give me some advice? I've tried various things within my capabilities, but nothing has worked. Firefox 150.0.1 64bit
