Firefox Community Forum

Here is what the message says: "Firefox is trying to install a new helper tool. Enter your password to allow this" I tried to install but Firefox won't open. Firefox icon just bounces around, I have to force quit to stop it. I DO NOT WANT THIS TOOL BUT I WANT TO USE FIREFOX. By the way this is sent from my other user, as the problem is on my admin. user and I can't open Firefox to do anything!

Tell me how to get rid of this. All of them say via either some numbers and letters, but the company name says zyvennero.co.in. You can click "Dismiss" which does nothing, of course and others just continue to pop up.

I always have two windows of Firefox open, one for each monitor. Up until recently Firefox would always restore both windows exactly as they were before I right clicked the Firefox icon in the taskbar and clicked "close all windows". This week however my browser will only restore one of the two windows I had open, and I have to restore the other one manually which is annoying. Can anyone help me bring back the old behavior so it restores both my windows every time?

How do I change the email account inserted by Firefox when I click on an email link?

I have previously changed the main email address (added secondary address, swapped secondary for primary, deleted secondary) but when I click an email link in a web page to write an email to the web page business, the old deleted email account is used instead of the new one. This old address is not listed at all as far as I have seen in my Mozilla Account.

Windows 11 Pro on Lenovo ThinkCentre. I switched to ESR a while back, when the regular and ESR versions coincided. All updates since then have worked fine, until now.

When I allow Firefox to update to 140.3.1esr from 128.14.0esr, then the Firefox browser no longer works at all. It comes up, but entering a URL (by typing or bookmark) does nothing and goes nowhere, so I can't use the internet at all.

I had to use Macrium Reflect to restore my system drive to an earlier time to get back on the internet, using version 128.14.0esr, which lost some recent bookmarks, etc. I have tried this twice, with the same result.

Now, a couple of sites no longer work because they say the browser isn't current.

What can I do about this? I hope I don't have to switch to another browser, because there are Firefox extensions I use all the time. However, I can't use a non-updatable browser indefinitely, because more sites won't work.

Can I fix this?

Thanks for your help, AnneF

For years I have used Firefox to access my Bank of America online account. I am also using Quicken kinked to Bank of America. Today, when logged into bank of America, every action I take results in being sent back to the sign on screen. After clearing with Quicken Support as requested by BOA, I was directed to use a different browser which worked normally. I was told by BOA that the issue was with Firefox.

Hi everyone,

I’ve noticed that Firefox tends to use a lot of memory when I run several browser-based tools at once — especially web calculators or dashboards that update data dynamically.

For example, when I’m testing a lightweight web calculation app (something similar to a gratuity calculator that updates values in real time), Firefox memory usage slowly increases, and sometimes the browser even freezes if multiple tabs are open.

I’ve already tried:

Clearing cache and disabling extensions

Running in Safe Mode

Using hardware acceleration on/off

Still, the problem persists.

So I’d like to ask:

1. Are there any specific settings or flags that can help manage memory usage better for interactive web tools?

2. Does Firefox handle JavaScript-heavy calculations differently compared to Chromium-based browsers?

3. Any recommended performance tweaks for developers testing such tools locally?

Would really appreciate advice from anyone who’s optimized Firefox for this kind of lightweight, web-app testing.

Thanks in advance! 🙏 bold text
