Firefox Community Forum

Good day all, I cannot login to both my desktop and laptop at the same time. I have changed my password several times, and even though I know it is the correct password it still tells me the password is incorrect. I can login to one at a time.

Example: I login to desktop with new changed password but when I use the same new password on my laptop, it says it's incorrect. Even after several password changes.

How can this be fixed? I travel with my laptop and need to be able to sign in.

Thank you for reading!

Hello! i wanted to report that i got an small annoying white outline formed around the screen, i tried to reset every preferences, yet didn't worked, to reload Firefox? neither work. It's only appearing on Firefox, not anywhere else. Someone can help me to get rid of this white outline? Thanks!!!

I've posted an picture of the issue down below. (also ignore the fact it's in French)

The iDrive backup app on my synology nas is accessed via a web browser over my local network using an ip address. It has a two step security setup. First to enter Synology credentials and then iDrive's. After entering the iDrive credentials, all I get is a spinning wheel. It is supposed to present a box to enter a validation code, sent to me by email (which I get). The box is never shown.

The process works in Chrome and Edge successfully. I contacted iDrive support and they told me that since it fails only in Firefox, that I should contact the browser vendor.

There is no error message.

I tried clearing my browser cache, restarting Firefox and my computer, none of which helped.

Please can you advise me?

Firefox 137.0.2 (64 bit). Windows 10 Home 22H2 Os Build 19045.5737.

One page of Firefox 115.21 opened and Task manager memory usage for Firefox reports-:

1) 9,956 K 2) 46,288 K 3) 11,564 K 4) 55,268 K 5) 21,560 K 6) 9,996 K 7) 5,516 K 8) 302,924 K 9) 40,272 K

These are ALL marked Firefox and in order on my Task Manager, the Page 'opened' was Firefox help forum ,,,, some memory usage here, is this right????

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!

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!

I have an Office 365 account through work and I'm using Copilot frequently. In Firefox I have a pinned tab for Copilot.

In recent weeks I've run into issues where the Copilot page stays essentially blank, i.e. the message field to enter text does no longer appear. The Office Toolbar still appears and when I switch to other Office365 sites like OneDrive and Home they work just fine. The problem only exists with the Copilot page. Refreshing the page does not solve the problem.

I found a temporary work-around by clocking on the lock-button in the address bar and selecting "Clear cookies and site data...". After doing this and refreshing the page it works fine again, but only for a while (like maybe the rest of the day). I don't know exactly what makes it break, but it seems like I have to apply the work-around on a daily basis almost.

Additional Info: I've been using this setup for at least a year and the problem only appeared in the last few weeks. If I open Copilot in either Chrome or Edge I don't have this problem (but I also don't want to use Chrome or Edge).

Bonjour, depuis 2-3 semaines je ne peux plus me connecter sur certains sites (exemple: AIRBNB) avec Firefox: J'y arrive avec un autre navigateur comme chrome. J'ai désinstallé - réinstallé Firefox mais le problème persiste. Avez-vous une solution? Merci, Nathalie

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?

Bonjour, Voilà, depuis une mise à jour de Windows 11 la kb 5054979 et la kb 5055523 fêtent ensemble j'arrive à accéder à Firefox à l'aide de la souris mais dès que je tape au clavier Firefox plante. J'ai essayer la mise à jour des pilotes du clavier croyant à un problème de drivers mais il est à jour. J'ai désinstallé les mises à jour mais rien n'y fait J'aimerai savoir d’où peu provenir le problème ?. Firefox envoie bien des infos sur le plantage et essaye de remettre les onglets mais le problème reste le même. merci pour votre aide ? Je n'ai rien trouvé correspondant à mon problème dans les articles d'aide

When I used a VPN I got this message

   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

How do I check?

Or does Mozilla have a vpn I can use?

Thank you Greg

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.

As the first screen capture shows (sorry it's in spanish), my PDF documents tend to not print on the full page, but rather only on the top left corner of it, i've already fiddled with the scaling and fit to page, i have cleared the printer settings from mozilla, still the same, ive gone into the about:config menu and changed paper_height, paper_width, shrink_to_fit, and scaling nothing works. The document prints fine on Edge (screenshot 2), no problems with fit, and what's even crazier is that some PDF files work just fine (Screenshot 3). Honestly i have no clue what else to do.

My computer downloads your updates over and over again, tying up my computer--none of the downloads ever loads This problem is can only be fixed by pull the plug restarts as these downloads will not stop until I do this

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?
