with this new version i lost everything i need to get back to an older version and get all my extentions my bookmarks back all my s desktop items that i had linked to firefox are gone i can no longer get face book or anything back to firefox book marks every thing i had with firefox

and

i go to chrome have no problem getting and keeping Facebook i have closed and enable the extensions removed some and it either does not work or takes for ever in the version of Facebook. . I keep checking if Facebook is down there are limited problems but i do not see the problems in Chrome. if this keeps up i will be going to chrome which i really do not want to

Since I upgraded from FF128-esr to FF140-esr I always get the "Firefox is being updated by another instance" This is really driving me crazy, as I checked / did / .... everything (and even more) I found on the internet related to that.

Nothing helps !

Creating and using a new default profile didn't help

Finally I ended up uninstalling FF completely (making sure no -zero- leftovers remained in ProgramFiles, AppData a.s.o.), and reinstalled FF140.7.0-esr freshly. After installation I started FF immediately with the created default profile (only existing one) --> SAME THING : "Firefox is being updated by another instance"

And this is really a FF140 thing, when I go back to FF128, on the same computer, same profiles, ...., the problem is gone.

I would like to know in detail what checks are really done by FF to decide to give that "Firefox is being updated by another instance"

Two days ago, I made my first post to these forums. Now I'm being spammed with "Congrats on your first forum reply!" emails from this website. I am getting a new one every hour and a half or so. There is no obvious thing to do in the email to stop this. How do I stop support.mozilla.org from spamming me?

Hi,

When I opened Firefox today, it asked me which profile I'd like to use. I named one Katy and then continued. Now, I can't see any of my bookmarks, none of my passwords are saved, none of my sites recognized. I've been using Firefox for years. Everything I have is saved there. I just want my old stuff back. I'm signed in on my account, but can't see another profile that I can choose. My phone still has all the passwords and bookmarks from before but I I can't see what profile I'm signed in under. Can anyone help?

Thank you!

Katy

As of yesterday my Firefox browser no longer displays some screens within Amazon Prime correctly. It displays what should be images as text, which is difficult to read, unlike Microsoft Edge, which displays the Amazon webpage correctly. I am running Windows 10 with a support extension through October 2026, so could it be an update from Microsoft Windows or Mozilla Firefox that has caused the problem. Thanks for your help.

I have all the location settings I can find on my Firefox browser, google, and device turned off, but the new firefox weather widget still had my hometown as the default location, which is is not the same location as my IP address. And when I went to buy a book online through Thriftbooks with a guest account the address line autofilled with addresses in my hometown. I do not have any addresses saved to autofill. Where is this information being stored and how do I get rid of it?? Is there something in about:config I can shut off or disable?

Thank you for your time and assistance.

I use eBird extensively. When I try to play the audio (with sonograms), I get a message that says "We are still processing this file. Try again later". These files perform well on my Android phone, so I know it it is not eBird's glitch. I am confused about the setting options on Firefox that I need to set. These files are usually .wav format. I have tried to open a ticket with eBird, but have not had a response. Can you guide me? Thanks.

I have been using Firefox profiles for years, long before the announcement of the new profiles UI. The new profiles UI launhed with FF 144. I'm on the latest version, which is 149.0.2 and I still don't have the new UI. Specifically, I do not see my profiles in the new UI.

When FF launches I see the new UI but my profiles are nowhere to be see as you can see in the screenshots:

https://postimg.cc/gallery/tFXz00m

I have 2 profiles and they each have their own name.

Instead I am presented with 2 option "Original Profile" and "create new Profile". When I click on orignal profile, Firefox opens my default profiles which has its own original name. However, when go throught the new UI o switch profiles, I do not see my other profile. Moreover, if I click manage profiles, I don't see either of my profiles.

The only way I am able to launch my 2nd profile is the old fashiong via "about:profiles".

Why can't I see my profiles in the new UI?

On my 2nd profile, I don't even have the new profiles UI.

Why dont't I have the new profiles UI months after you launched it?

Please help!

Reposting until I get help from someone. Windows/desktop. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. Somebody please help me if there's a way to active that function.

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.

My browser was recently updated to 150.0.2, and on the new launch page after update describing new features, it prompted me that the new free mozilla vpn was available to try. When I clicked on the link to follow the steps to set it up, it said to click the vpn icon in the toolbar, but I don't see that icon there. When I go to more tools -> customize toolbar to try to find that icon to add it back, it doesn't appear among the toolbar options. Is this something I still don't have access to because it's in a limited beta, or is there some other way I should be accessing this?

Home Internet speed via cable 500 Mbps. When checking the Internet speed through the Firefox browser (version 133.0.3), incoming and outgoing about 250 Mbps. That is, the browser cuts the speed twice. When checking the speed through Google Chrome (version 145.0.7632.160), the Internet speed is about the declared 500 Mbps. Please help solve the problem with Internet speed through the Firefox browser.

I bought Mozilla VPN a month ago, and nothing has turned up.

How do I get a refund of my money?

Then I can buy StartPage VPN.

Firefox is really going downhill.

This has happened several times in the last 4 months or so, it had never happened prior to that and I've used Firefox for years. It now occurs when I open Firefox after my computer has either been shutdown, or the computer does a restart. I am signed in to my Mozilla account.
