Hi all, I used to run two Firefox instances on the same computer, each one using a different account (as I mentioned in the Subject), but I don't remember how I managed this, so now that I moved to a new computer I can't reproduce it! Thanks for helping, if anyone knows. Regards, Mike

in FF 137.02 Win11Pro there is no reopen previous session option in the history menu, even though in settings, history, "firefox will" is set to remember history. We tried reinstalling FF. No luck.

Is there a way to reopen the previous session?

Has that feature been deleted?

I DON'T KNOW IF I CHOSE CORRECT TOPIC, BUT I CHOSE THE DARK READER MODE THINKING IT MIGHT BE USEFUL FOR MY EYES. BUT I DON'T REALLY CARE FOR THE DARKNESS OF IT, AND I CERTAINLY DON'T WANT TO HAVE TO PAY FOR IT. BUT I'M NOT SEEING WHERE I CAN DISABLE THAT AND GO BACK TO THE WAY IT WAS BEFORE. PLEASE ADVISE.

Dzień dobry, Dlaczego po zalogowaniu się do swoje poczty nie są wyświetlane ilości wiadomości np w folderze Spam, Kosz itp. A w folderach są wiadomości. Wcześniej nie było takich problemów.

Hi!

Yesterday, April 5, 2025, my Firefox started displaying this message for every search typed in the browser:

"Our systems have detected unusual traffic on your computer network. This page verifies that it is really you, and not a robot, sending the requests. Why did this happen?"

I tried a few solutions: I cleared the cache, restored Firefox, reinstalled Firefox, restarted the internet modem, reset the computer's DNS using the ipconfig/flushdns command, scanned for malware with Windows Defender, and scanned for viruses and malware with Kaspersky, but the problem persists, both in the normal tab and in the private tab.

I contacted my internet provider, and they said there is no problem on their side.

In Firefox, I always use the default search engine "Google".

When I change the search engine to "Bing", the problem does not occur.

The problem does not occur in the Google Chrome browser, only in Firefox.

I am using Firefox 115.22.0esr (64-bit), Windows 7 operating system and internet connection via network cable. I only have one computer connected and I don't use VPN.

Please, can you help me?

Thank you!

Hello, Microsoft Defender apparently detected a trojan, located in the folders for the Firefox extension Malwarebytes Browserguard Trojan description: Trojan:Win32/Nibtse.c!tsk

Is this a false positive?

Synced my new computer, received bookmark toolbar and 10 year old bookmarks from when i switched from interent explorer, but all my more recent bookmarks and bookmark folders are still missing on the new computer. Also didn't seem to transfer passwords and autofill info.

Hello,

Earlier today I reformatted my device but when I logged in to firefox I can only see my history is getting synced my bookmarks are empty, I've checked and bookmarks are check off and they should be synced. How do I get them to sync? It has worked fine in the past. Thanks.

1. I accidentally moved the address bar in Firefox and I cannot get it back where it belongs. This is causing me and inordinate amount of stress. It should be simple. I want the address bar back at the top. Not in the middle, and half way to the right of the screen. 2. Webpages are now displaying with "blank" space on both side of the window. 3. The bookmark bar comes and goes. In the screenshot... it has disappeared again.

Reinstalling Firefox did not help at all. Please help... this is stressing me out far more than it should.....

Why do I need to enter the PW every time I start Firefox, even when not accessing the information? This is a ridiculous loss of time. You really want user to migrate to more user friendly browsers?

I was not sure which "topic" to select. I use Yahoo mail for email. Up until a month ago or so, I was able to type the first few letters of a person's name and the email address for that person automatically filled in. This no longer works. The only article on Yahoo's "help" that I could find said it was probably a browser issue.

Any ideas on how I can get my cache back? Or at least start over?

The server at 192.168.1.1 is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

How do I change the time out to a longer time?

I just started having an issue with my browser where every time I tab out of a tab playing media, the pop-out video appears on its own. It's quite annoying. How do I stop this from automatically happening?

I put music on my profile page on FUBAR.Com. I change the music each week. I have used FIREFOX there for two years or so with no problems.

Today I changed the HTML (supplied by YouTube) for the music but when I look at my profile page I get an error message that says I need to be signed in to insure I'm not a bot (a post from YouTube). After a lot of discussion it was found out that when other users view my page they see and hear the music video just fine!!??

What's the problem> FUBAR support says it's FireFox???

PLEASE HELP ME I don't want to go to a microfrost browser!!!!!!!!!!!!!!!!! I'm running WIN 10 and will stay there! Thanks Donnie

I’ve noticed that Firefox consumes a lot of memory, especially when I have multiple tabs open. Sometimes, it slows down my entire system, and Task Manager shows Firefox using over 1GB of RAM even with just a few tabs. Other browsers like Chrome or Edge seem to handle memory better with the same number of tabs.

I’ve tried restarting Firefox, closing unused tabs, and disabling a few extensions, but the problem keeps coming back. I even checked techsquest.com for tips, but I’m still struggling. Are there specific settings, hidden features, or optimizations I can apply to reduce Firefox’s memory usage without sacrificing performance?

Here’s what I’ve already checked:

Firefox is updated to the latest version.

No unusual extensions running (just uBlock Origin and Dark Reader).

Hardware acceleration is enabled.

Any help would be appreciated—thanks in advance!
