Since recently 1~2 version, my Firefox keeps consume large amount of memory and release it repeatedly

Even I restart Firefox and do nothing, it will start doing this again

I use about:processes and about:memory to capture this seems the main process's "tab.query" causing this, please check

PS: sometime it will consume till system max (64GB) and cause my OS out of memory. PS2: that wave-like memory usage is cause by Firefox

Before upgrading to Firefox 140, I would always quickly switch between my default DuckDuckGo and alternative search options, like Wikipedia, using the up and down arrows. I would just type the search term in the address bar and then tap the down key a couple of times before pressing enter if I wanted to use a different search engine.

The new address bar no longer seems to offer this option. I see I can still select alternative search engines using the mouse, but pressing the down key no longer lets me select them.

Is it possible to re-enable this way of quickly switching between search engines using the keyboard?

When using any Microsoft 365 product on the browser I keep getting a prompt to "Please sign in" although I am already signed in. I can click the Sign in button and a about:blank page pops up for a split second. Then within a half hour or so, it will pop up again. I deleted my cookies but the problem still persists. Does not happen on other browsers.

I am having an issue where my browser does not show the webpage title or website name when it returns results. I haven't changed anything about my browser recently and I'm really unsure of what is going on. Any advice to fix this would be appreciated.

Whenever i search something on google, firefox desktop (all fine on android) is failing to display the ai(gemini) answer no matter what questions i ask.

Same happens in the "AI Mode" option that is available in google's recent update.

And, I,m logged in.

This started since a week, everything was working fine before that.

I'm getting a PR_CONNECT_RESET_ERROR on my PC when trying to web browse. Same problem with other browsers. Was working fine till a few days ago The URL box has 'Not Secure' before each URL address I try. Have looked up solutions on YT to no avail eg clearing cache etc

My Laptop has no problem with this.

Hi! I recently lost my old laptop and I'm trying to setup my new laptop without a backup. I was logged into my mozilla account on my old browser before I lost it, but I'm not seeing any of my old tabs, bookmarks, and extensions from my old browser syncing to my new browser. Is there anything I can do to retrieve this data without having access to my old laptop? Thank to anyone who can help!

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

I've been using tab grouping and it is really helpful.

But this morning when I created a new tab group called "MISC" I was unable to add any tabs to it.

1. I noticed that this new group happens to be the 11th group I've created. So I'm guessing that there may be a limit of ten groups. Am I right?

2. And now, some hours later, I see that the new MISC group does appear on my tab bar, but one of my old groups, TECH, has disappeared, but its contents seem to have been added to the MISC group.

After the most recent update, all of my Firefox tabs, bookmarks, and general UI fonts have gotten larger. Is this intended or a bug? There are not options that I know of to reduce the size of the fonts to how it looked previously either.

Lately I installed a new PC, and tried to download FireFox and sync my data. But my data seems like a few years ago, not as new as another PC I have now. I'm sure I have logged in with same account on them, how's this happend?

Why on earth would you remove the ability to select move multiple tabs anywhere in an open window browser???? Until recently, I could select the first and last tab, hold shift and move them anywhere I chose. Now that feature doesn't work at all. It duplicates one tab or I'm given a choice to move to the front or last of all open tabs! Please give me the feature back!!1

The errors I get are kind of all over the place though. I've completely deleted and reinstalled Firefox, and removed all extensions too.

It will loop to the login screen over and over, or I get the message 'An error has happened, try again later'...

I used the browser console and didn't get anything that seemed usable. I use Strava nearly every day so I'm having to use Safari. And this issue is on all of the mac and Windows systems I use. 'Troubleshooting Mode' didn't work either.

Help!

How to get rid of the half-dozen old search sites from very top of each new page, directly under browser box. Those sites are places I no longer use, e.g., from my old job; from a Wiki search done ages ago. I have searched for help. I never see "three dots" when I hover my cursor above the offending items.

I was using Chrome. My daughter recommended Fire Fox for my MacBookPro. I did. Now I need to clean up this problem.

Thank you.

PS: I don't know which topic best describes my question.

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

literally what the [expletive] was the thought process in making it so that when u import all ur passwords from a csv it AUTOMATICALLY DELETES "DUPLICATES" WITHOUT CHECKING AT ALL WHICH ONE IS CORRECT. I HAVE SO MANY [expletive] PASSWORDS THAT ARE WRONG BECAUSE UR [expletive] BROWSER DOESNT ALLOW ME TO [expletive] MANUALLY CHANGE THAT STUPID OPTION. WHAT THE [expletive] WAS THE THOUGHT PROCESS IN MAKING IT [expletive] AUTOMATIC???

Alternative search engines no longer appear when typing the stasrt of a search. Am able to set alternative search engine in settings but need to go back to settings if I want to use another one. This happened after a recent update - perhaps as much as a week ago.

I use an independent password manager to store my passwords and prefer it over Firefox's because it has a highly customizable generator for creating new passwords. However whenever I am on a new site, Firefox pops up with a prompt to generate a secure new password (it appears as a drop-down from the item text box). My password manager also creates a pop up/drop down, but it is hidden behind Firefox's and I cannot access it. I need to be able to disable the secure password generator prompt. Please take a look at my excellently annotated screenshot, attached.
