Diễn đàn hỗ trợ Firefox

The alert message appears everytime I go back into gmail This browser version is no longer supported. Please upgrade to a supported browser. I checked that Firefox was last updated Feb. 26. So I'm understanding what's going on. thanks

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

Firefox just updated, now getting ACCESS DENIED at common sites, Home Depot, JC Penney, American Airlines, United Airlines and I don't know how many more.

How do I fix this or go back to previous versions of Firefox?

Or just move to Google?

For over a year, my browser occasionally loses connectivity. It may work for 3 hours or 3 days, but inevitably new tabs will stop working and then slowly the others will stop as well. When this happens, none of my other browsers are impacted. They work fine. It is only Firefox. The only solution is to close everything and lose all my work.

Once I do that and restart Firefox, I receive an error message telling me I am using an older version of Firefox that is not compatible with my profile. The only solution that brings me back to the best starting place is to re-install Firefox.

My company IT spent 3 days trying to find the problem and couldn't. I have uninstalled and reinstalled so many times. All extensions are turned off, as are the two add-ons. I have been using Firefox for over a decade and prefer it to all other browsers, but I need to find a solution or I am going to have to move on. Help!!!

I need help with a problem that has tortured me for weeks. I use debian 13 with plasmakde. I don't know why, but when I connect to a wifi after some time it doesn't work anymore ONLY with Firefox. I can perfectly use any other app which requires internet but firefox. Sometimes it gives me the error "The connection has timed out", sometimes the error "Unable to find the proxy server" (even if I selected no proxy in the network settings). I searched online but I couldn't find anything helpful, so I can only hope to find a solution in here. Thank you very much in advance!

Hi,

I updated to Firefox 149 (German User) and did not get the Seutp prompt mentioned in https://support.mozilla.org/en-US/kb/built-in-vpn#w_turn-on-vpn-in-firefox I Also tried https://support.mozilla.org/en-US/kb/built-in-vpn#w_how-do-i-turn-off-or-remove-vpn-from-my-toolbar to check the Optiions in the Settings, but there is also the part "VPN" missing. In the Help Section it says that I have installed 149.0 (64-Bit) Windows Version. Is there something missing?

best regards

I use the web client of Outlook for my work email. However, I've run into an issue: while I can log in through Firefox, every so often (and lately it's been quite often) I launch the Outlook webpage, and all I get is just a bunch of code (see image). The only thing I've found that makes the page work again is to clear all cookies and cache, and clear the start-up cache, and then launch Firefox again. Obviously, this is very annoying, since I have to log in anew every time (and use 2-step verification, etc.). Does anyone know how I might fix this more permanently so I don't have to keep clearing all my cookies and logging in all over multiple times a week?

All of a sudden I cannot save bookmarks. Neither the instruction "To bookmark a page, just click on the star in the address bar." or using the "Bookmark Current tab..." in the Bookmarks menu do anything. Trying either method just sits there and does nothing.

Hello, for some time now I've been experiencing a number of problems with the latest Firefox updates.

Today I have version 152.0 (64-bit), which was updated again this morning. I restarted my mid-2015 MacBook Pro Retina. I have fiber optic internet, which is very high speed.

I've been using Firefox for over two years.

1) For the past eight days, I've been experiencing many problems with Google Meet; I get freezes, audio and video dropouts...

2) For the past three days, I haven't been able to log in to this website: https://creators.spotify.com/pod/login

3) For about ten days, I've been having trouble logging into my Stripe dashboard, with significant slowness and/or crashes.

4) In Notion, I'm also experiencing significant slowness, with pages taking a long time to load.

In short, several problems that I didn't have at all a month ago or before.

But now it's a nightmare.

I don't have any of these problems in Safari or Google Chrome.

So what's going on in Firefox?

Why is it such a hassle?

Thanks for your feedback.

Description: I need help with the "Firefox Multi-Account Containers" extension.

The extension is installed and shows as "enabled" in my Add-ons Manager. However, the colorful container icon does NOT appear on my toolbar, so I cannot access or use the extension at all.

What I have already tried (none worked):

· Dragging the extension icon from the puzzle menu to the toolbar · Right-clicking on the extension icon (inside the puzzle menu) to see if there is a "Pin to Toolbar" option — but the option does NOT appear at all · Restarting Firefox multiple times · Restarting my computer · Creating a new profile in about:profiles and testing the extension there — still no icon · Disabling and re-enabling the extension

The extension is installed and enabled, but without the toolbar icon, I cannot create containers or separate my Gmail accounts. I really need this feature.

I have read that this might be a bug in recent Firefox versions. Is there a known fix? Do I need to completely uninstall Firefox and reinstall it? If so, could you please guide me on how to do a clean uninstall (removing all profile folders and registry entries) and then install the latest version?

My system is Windows (older version, if that matters).

Thank you very much for any help!
