Hi, it looks like Firefox can copy links from selected tabs, using right-click menu. It doesn't work for non HTTP(S) addresses though, such as "file:///C:/Users/USER/etc."

Is it possible for non HTTP(S) addresses?

The add on Export Tabs URLs by AL is very good, has the option for non HTTP(S) addresses, but I couldn't get it to work for selected tabs, is it possible for selected tabs?

So every few days now if the free VPN is on I get my tabs locked into an error. I get that warning screen and sites stop loading or partly load, before the VPN update I never had to close Firefox this often, if left idle with the VPN on this seems to happen faster, I have left the VPN on overnight and I tend to nearly 90% of the time wake up to this error, if I disable the VPN fully I can pick up where I was but cutting it back on I have high odds that it will break, Firefox is idle while I do other stuff and the VPN is on, I get that error and I get to watch the weather app give me it's error. I have never had Firefox fight my antivirus It worked fine for ages, and only now do I need to reset Firefox by force now every 1 to 3 days. I use to be able to leave tabs open, but now they always error out in a few days. It could be other things, I just never had problems like this until now, it's so common and in the same time tables.

Signing into Netflix it only requires my email address. Then it gives me a message that captcha is required, then gives me an error message, then puts me through to my account. Anyone in the world using your browser and my email address can access my account.

Both Mozilla products spontaneusly disappeared from my computer. Firefox requested a reinstall, and all was recovered. Firefox completely disappeared, and I had to restore from backups. I am seriously worried. What is going on?

When I search for something it shows up in English, but some text under the result is French as shown in the picture. I use latest Firefox with Google search engine, and I have all settings in Google set to English, And same for Firefox settings

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.

Moderator note: This question has been edited to correct the formatting.

I'm reposting a question already opened here because a moderator suggested to do so. Actually I though I was posting to the international forum from the URL...

I was trying to access a local HTTPS website of an embedded device (a Siemens S7-1500 PLC) that is using a self-signed certificate, but was unable to go on (attached image #1, in Italian language) due to the the SEC_ERROR_REUSED_ISSUER_AND_SERIAL error. I've browsed a similar PLC webserver in the past, so the fact that the device exposes a similar certificate serial number is not so strange for me, considering also it's self-signed.

The problem is that I cannot follow the instructions of the Mozilla knowledgebase here because I'm not able to identify the correct certificate of the website!

In the attached image #2 you can see that the connection is detected as not encrypted, I suppose because only the form part of the HTML that is posting the data using HTTPS while the rest is using HTTP, but I'm not sure. If I click on the padlock icon (attached image #3) the info about the current certificate is not displayed.

Then I went into Tools > Options and searched for "certificates"; as you can see in the attached images #4 and #5, neither in the Servers tab nor in the Authorities tab I can find any item that is related to 192.168.10.2 (the webserver IP address) or Siemens (the embedded device manufacturer). But unfortunately the error persist! Initially there was a 192.168.10.2:443 line in the Servers tab and I removed it and restarted Firefox, but it didn't solve, so at the moment the situation is the one depicted by the attachments.

I had to use Microsoft Edge to access the website, but I would like to solve this issue and use Firefox instead. Is there anything else I can do to bypass the error? Why doesn't the error page provide a way to correctly identify the wrong certificate using its fingerprint and/or name? Or, maybe, is there a way to disable this check for local IP addresses or for items in a whitelist?

Thanks for your help.

I tried to remove the new 'profile'. I don't want it. now ALL my data, settings & bookmarks are GONE ! Help me revert to & restore the previous account settings !!!!!

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?

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 :)

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.
