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

Hi

i use Mozilla at work, in logistics.

When booking shippments we use "nShift". Booking is repetitive, so the autofill function (in swedish its autofyll) is pretty useful, and we have used it extensively...now for some reason it has just disappeared and we cant get back.

See uppploaded imgage, tried to follow the instructions,..... also in my edition there is no subheading caled "Formulär & autofyll", it just says "Autofyll".

So the question is, what to do to get the autofill back.

Thnaks for all the help i can get.

!. link to youtube only flashes then plays only audio. Full video requires opening link in a new private browser window

2. Typing into search bar for Duck Duck Go in new tab page types directly into active bar...

3. Active bar is no longer at the top but is in Bookmarks toolbar...

I suspect some update problem.

Hello, I have spent the last couple of hours reading through other questions and posts but nothing seeemd to work. If I try to copy a shared link in OneDrive or SharePoint on my desktop and then paste that link into Outlook Web App, the paste function does not work. The option is there, but the actual pasting does not materialise. CTRL+V also does not work. The only thing that does work is if I paste the link into another window first and then copy again, and the CTRL+V works. Right click and paste never works. I have tried this in a private window and in safe mode. I have also checked the clipboard settings in about:config to make sure they are not working against me. It works fine on Chrome. I made a quick Loom to demo the issue: https://www.loom.com/share/911ae68d614947aa9ea6beaba0d2f5b0?sid=2257b601-939b-4d95-90d8-bb2c95b1ed81 Firefox is up to date, as is Windows. It has been like this since I moved over from Chrome a few weeks ago. Is this a common issue or a 'me' problem? I have seen all the workarounds, but I am trying to understand why right-click, paste just doesnt work. Any suggestions are much appreciated.

Apparently y-all aren't to smart to understand the your customers do change their telephone numbers and email address from time to time. It appear to be to smart to have instruction to alert you customers to the location of the forms to be used to change passwords, customer names and email address. ya think?????????????

After instalation Eset Smart Security 18.2.18.0 with full security browsers my Firefox is run only in read-only mode. If I will be disable option Security browser and run Firefox that's working. Next I will be enable option Security browser then Firefox starts with green frame. After close Firefox and next run then starts read-only mode. Eset Team is not fair play becouse resolving problem only disable option Security browser. So why is there an option that prevents Firefox from launching? All my portable browsers without Eset Security working without any kind of problems, for example Tor, Opera.

I can't re-open a saved tab group. I saved it and closed firefox but when I returned I couldn't find where to access it. I see all of my saved tabs when I right-click on a tab and choose "Add Tab to Group", but when I move the tab to that group it just disappears rather than open the group. Any help would be appreciated! :)

I was, admittedly, perhaps doing a bit much on my ram at the time. but i didn't expect this. i didn't expect it at all.

screen went black a moment, firefox crashed. I figured it was fine! it crashes sometimes. it always restores my tab. the little bug report was there! willing and ready to restore my session for me. i let it restart fox.

i get the firefox sesion restore tab. but i already am filled with dread and upset. because i can see, in my peripherals, the blue button to restore session, is already greyed out. checking the little drop-down that shows you your session- [expletive]. empty.

God. what the [expletive]. I- what the [expletive]. it's a stupid thing to cry over, im sure. But some, most, of those tabs were YEARS old, from when i moved. and i've been having a hard time thinking about my old home lately. and now i've lost another bit of home. Some of those tabs may not even be in my [expletive] history anymore; i have a weird cut off of my oldest history in the history window, library window, thingy, where i can tell history was wiped, but i never wipe my history. i have no clue why this wipe even happened! Other then pushing it on my pc a bit much, but it's not been the first time i haven't paid attention; and it's restored before! what the [expletive]. Deeply upsetting. i've tried, even, to restore things myself; i have a 'upgrade.jsonlz4' file, few months old, but enough to have most of my tabs if it were stored inside; tried to rename it one of the recovery files, 'recovery.jsonlz4' and 'recovery.baklz4', then both, but doesn't work to get my windows back. This is awful.

Hi All,

I was using the following CSS to hide the navigation images and show only text labels on the context menu for the Back, Forward, Reload and Bookmark Page menu options...

/* Content Area Context Menu - Navigation Vertical Text */
#context-navigation,
#context-navigation > menuitem{
  flex-direction: column !important;
}

/* hide images */
#context-back image, #context-forward image,
#context-reload image, #context-stop image,
#context-bookmarkpage image{
   display: none !important;
}

/* show text labels */
#context-back:after, #context-forward:after,
#context-reload:after, #context-stop:after,
#context-bookmarkpage:after{
   content: attr(aria-label) !important;
   margin-inline-start: -19px !important; /* this pushes navigation text items to left, aligned with other menu items below */
}

It worked up until a couple of versions ago, but something has changed, and my CSS is now broken, and those navigation icons are back.

My context menu now looks like the attached image below.

Any help with showing only text labels on this menu is appreciated.

Thanks.

In the past I've been able to print pages generated from websites, such as ... https://www.bridgebum.com/short_suit_game_try.php

I recently used a well know "cleaner" to remove broken links etc ... Since then I've been unable to print these generated pages. I can still print documents that I've created. mail etc so it's not the connection between my PC (Windows 10) and the printer (canon TR7560)

I've tried the troubleshooting ideas in FAQ. I've reinstalled (without uninstalling) Firefox but neither helped.

Your browser dead ass just doesn't respond when I click on it. I have a new mac mini 4 and have the latest update for firefox. it's absolute dogshit to be honest. I'm lucky if the browser lets me click on anything, eg., bookmarks, add-ons, history are nonfunctional. Also my tabs on the browser get squished together and superimposed such that 2-3 separate tabs appear as though they are one tab. I have never had an issue like this before when using firefox. I don't encounter the issue with safari or chrome, but I don't like those browsers. Do you have insight as to why firefox mozilla is suddently ass?
