Recently passkey function stopped working for Roboform which requires entering password for each login event. Roboform support indicates the issue is being caused be Firefox function. Please advise on this issue. Thanks,

Halfway through today I'm unableto access three sites which I use regularly.using a VPN: 1337X.TO EZTVX.TO THEPIRATEBAY.ORG

Getting the error message:

An error occurred during a connection to thepiratebay.org. PR_END_OF_FILE_ERROR Error code: PR_END_OF_FILE_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem.

I am able to access THEPIRATEBAY.ORG with Opera <ptooh> so the site itself obviously doesn't have a problem.

I've tried changng my VPN location from the UK to Amsterdam, NL and to Washington, USA but none of those locations have helped.

My wife needsher daily fix of American soaps and Police dramas which never get to us here in the UK

How can I get around this, I really don't want to go down the TOR route unless I absolutely have to.

We had a power outage in our area. Afterwards when the power was back on I could no longer get CNBC.com to work properly. It kinda opens but nothing goes live nor do the videos play. If I switch to Chrome everything works, but I like Firefox! Lynn Nichols

Hello, I have Windows 7 and I use Firefox ESR as my browser. It has work correctly for years now, but since a couple of days it has problems with downloading the latest updates. It asks me download the update but as I go into the settings page, the download is stuck at 0 kB. I also get a message box that FF is not able to download the update and it sends me to a Mozilla Firefox ESR download page and when I want to download the ESR version, FF cannot open the page with the installation file. Also many other links on the Mozilla page do not open or do not open correctly. Also it doesn't open this support page, I am writing this messages through my phone. Also it doesn't open the website bol.com. So what can I do. I have already tried clearing the cache and cookies. It doesn't help. I hope you can help.

help me restore my open windows. this has also happened a couple times before and its very frustrating when i have tabs open to read/refer to later or am in the process of reading and then i have to try and find them all again.

Firefox runs some sites slows on one of my Windows 10 computers.

I'm running Firefox on 4 Windows PCs and 3 of the 4 work just fine using the same synced profile.

Fidelity.com and Amazon.com are 2 of the sites that are very slow to load. They will eventually load, but clicking on any links causes another slow load.

The same web sites are fast when I use MS Edge.

Troubleshooting steps I've taken (none of which have worked):

• Refreshed Firefox
• Created a new profile
• Uninstalled Firefox leaving my old profile
• Completely uninstalled Firefox and deleted my profile

Any thoughts on troubleshooting steps to take?

I've done recent updates (May 2026) and after having 3 updates in recent months, I still have difficulties with my video programs (both Zoom and "One-click) slowing down during my work which is 100% virtual. How can I revert to an earlier version where this was resolved, please!!??

Recently (about a month) I have found I often have to login to my Firefox account in order to access saved passwords etc. Sometimes from one day to the next. It never used to do this. Can't find any setting like "trust this device" or similar to stay logged in.

Ever since the last update of the Firefox program, I am frequently getting the "Server Not Found" message when I click on links online. If I switch browsers, the links work just fine so it is obviously Mozilla's problem and not anything with my "modem or router" as I am told int he "what can you do about it" message on this error. Mozilla needs to look into this problem and update whatever is causing the failure to link message.

An error occurred during a connection to tpz.sashacare.com. SSL received a record that exceeded the maximum permissible length.

Hi all,

I have another query ongoing which trying to fix seems to have caused this problem: https://support.mozilla.org/en-US/questions/1581166

I'm logged into Firefox account and have everything synced. I've logged multi-account containers (MAC) into my Firefox to try and sync accounts. However, the containers are not syncing AND I now cannot send tabs to or from this instance of Firefox.

This started either after I refreshed Firefox or after I reinstalled it, I'm not sure which. Before Refresh I definitely had full sync, and I believe containers were synced but I had not changed anything in MAC for a long time, many months maybe years.

To try and fix this, I logged out of my Firefox account for both MAC and the whole browser, then closed Firefox. I then restarted Firefox, logged into my Firefox account and tested that I could send and receive tabs - I could, so that worked. I then logged into my Firefox account with MAC and tried to send a tab, and I couldn't, and nor did the containers sync. So, it seems that the MAC addon breaks sync.

A workaround is just to not depend on containers sync, but I'd prefer to get this back.

Any suggestions on how to fix this, or is this a bug in Firefox or MAC?

Cheers :)

Hello brothers and sisters, i am need help! I'm experiencing performance issues when surfing the 9GAG website. The amount of RAM consumed by this page is growing exponentially. It's gotten to the point where this tab can consume up to 5GB of memory, and that's not the limit. This issue hasn't happened before. I can't figure out what's causing it.

What I did to fix the problem: I reinstalled the browser. I reinstalled add-ons. I reset my old profile, saving only bookmarks and passwords. I reinstalled the operating system. None of this helped. However, my friends don't have this problem with this site. Please help.

Hi all,

After the last update the former Mozilla Test Pilot "Snooze Tabs" isn't working for me any more, I tell a tab to snooze and it just stays where it is. https://addons.mozilla.org/en-GB/firefox/addon/snoozetabs/

I've tried running with addons disabled and then running with addons active again and the behaviour is the same. It's the same behaviour whether I run from the toolbar or the context menu.

I'm presuming this problem is related to Firefox update mechanics. Any suggestions for how to get this working again please?

Cheers :)

Hi, Lately I haven't been able to add a bookmark icon on my 4-row new tab page. There's still to empty spots I would like to fill but can't find the usual + button. Thanks for the help
