I am trying to fix Firefox performance issues. I recently changed to Firefox to escape forced ads on chrome and the lost support for the Ublock origin. But I am having difficulty performing tasks and pages That I used to be able to do on Chrome with no difficulty.

When I open multiple tabs at once the tabs freeze up when trying to load and already opened tabs freeze and anything streaming also freeze. It takes tons of time to load multiple tabs and even sometimes single tabs depending on the website. This never happened with Chrome and I understand Firefox is not as refined as Chrome and is far younger than Chrome is but I feel like it shouldn't be this bad. Is there any settings maybe or maybe settings/preferences in the config area area that might help with faster performance and increased multitasking ability in the Firefox browser?

I have tried

1. Updating Firefox - I am running the most up to date version 2. Updating Graphics Drivers- I am running the most up to date drivers(Updated yesterday 11/17/2024 3. Deleting Cache/History/Logs 4. removed or disables unneeded extensions that I don't use every day and only activate when I need them.

None of this has worked to increase performance.

P.S. I would also like to fix the problem where firefox is using too much RAM if possible.

Can anyone help me?

I've been seeing this more and more, but my toolbar will change by itself every restart. The add tab button will shift all the way to the left or not appear, the bookmarks won't appear, etc. I'm not sure what can be causing this, and I saw no way to "save" my current configuration other than pressing the done button upon using the custom toolbar, which I had done every time prior to fix my configuration. Does anybody know why this is occurring, and a possible fix? Thank you

I am using latest firefox developer edition. After firefox updated automatically, I found that I lost toolbar customization settings. I reconfigured everything, but the next day when it updates I lost the settings again. It seems that there is a bug in Firefox. How can I fix this? If this is a bug, when will it be fixed?

I tried to create a default Windows profile with pre-configured app settings, including FF. I created a temporary user, logged in, installed FF and configured it, also installed some add-ons (first of all, ublock origin). Then I logged out, logged as an administrator and moved the temporary user profile to the default profile location (c:\Users\Temp -> c:\Users\Default), and then reset its NTFS permissions. This almost always works for all applications, including Google Chrome. I created a new user and logged in, opened FF. The settings were applied, but the extensions did NOT work, and even the buttons on the toolbar looked like empty squares. At the same time, the add-ons were present in the list of add-ons in settings, although without icons. It helped to turn off and turn on all the add-ons one by one, manually.

After some research, I realized that FF binds its settings to absolute paths to add-on files (*.xpi), specifically in the $profile/extensions.json and $profile/addonStartup.json.lz4 files. Google Chrome, for example, doesn't do anything simular, like the vast majority of applications. Removing these files from the profile will cause all add-ons to be "reinstalled" on first launch and set to a disabled status.

An easier way to reproduce the problem: 1. Run firefox -profile d:\temp\profile1 2. Install some extensions. 3. Rename profile1 folder to profile2. 4. Run firefox -profile d:\temp\profile2 5. Got it!

For what purposes does firefox bind to absolute add-on paths, and how can this problem be solved? P.S. I know about portable firefox from PortableApps.com, but I don't want to use a third-party loader for my tasks.

I have two installations of Firefox. One windows10 and one Linux. BOTH are doing the same thing on this site https://www.rapidonline.com/

I cannot scroll using the mouse roller. Page up/down doesn't work. Middle click and drag doesn't scroll either. BUT, for the briefest of time, BEFORE the Firefox shield in the address bar, I can scroll.

Hovering over the blue shield shows the text... Blocking social media trackers, cross site tracking cookies, and fingerprinters. Turning the Firefox protection OFF makes no difference, other than the shield is white and struck out. Disabling uBlock origin, or malwarebytes makes no difference. Both my installations do the same BUT, I called a pal who also uses Firefox on Linux and windows and he reports all is well and he uses uBlock, but not malwarebytes.

I have not actively messed with my settings on either platform. Oh, I was told to clear the cache. No joy.

Why does Firefox think it is blocking stuff but turning the protection off makes no difference? Why should two separate installations behave identically? Why does my pal's Firefox using Linux work on this site 100% ? I feel like I am going insane...

I have a custom pitch black theme ( pls add it without addons ) which now only flashes for a second when i open the browser and returns to the normal greyish dark mode. When i go to Firefox Color addon page and load it again in saved themes it stays pitchblack even if i open another browser window until i close all the browser windows .

WSJ did some sort of update and now things are broken in the regula browser. I've tried disabling all my extensions, putting multiple sites on the cookies exceptions list and turning off protection in regular mode and it does not work. Private Browsing works out of the box no issues.

The main way to know if you have issues is do you see the stock ticker near the top of the webpage, your name with account info, and some drop down windows. The Live Update sub-websites are broken. I think WSJ on some sites like those thinks I'm not logged in or can't verify I'm logged in.

Its weird. I've had similar things on FireFox before, what is regular mode doing? Why does Private browsing work? Can I somehow "force" the same settings in a regular windows on a per Website basis? This doesn't seem possible at this point.

Hello👋 I am using firefox developers edition on build 132.0b2 and my UI is not rendering correctly, the themes work but the objects like the bookmarks toolbar and the refresh button and the home button even some of my extensions is not loading and other things also not loading, but fortunately I know the keyboard shortcuts for these functions and they are working just fine but all the buttons are just not there My device is a Dell Latitude E7450 and it has a normal core I5 5300U so it is not an x86 arm based processor I hope that you find a solution ASAP as I am really struggling with my browser like this and btw I really love your work and the products that you give Thanks for doing the hard work! bye

Where did this strange language come from? I synced my laptop to my Android phone and somehow this language started appearing English and another language I can't identify.

hi and thanks --

all of a sudden, for no particular reason i can think of, my e-mail (gmail) has quit autofilling e-mail addresses when i type someone's name as a recipient. i haven't changed any settings. one day it worked, the next day it quit working.

help!

I haven't upgraded browser versions for a while and I'm now going from 109 to 132. Pretty bad I know.

I'm having a number of issues but for this post I'd like to concentrate on userChrome.css.

In version 109, I had a custom font for the top menu bar, the top menus, the bookmark toolbar, the bookmark toolbar menus, and the right click menus. I did this by including the following in userChrome.css (as per [https://support.mozilla.org/si/questi.../1335097|here]:

1. navigator-toolbox { font-family:"MyFont" !important }

This worked great, but it is no longer working in version 132. Obviously I don't know in which Firefox version this stopped working.

Has this been disabled by Mozilla or has it been changed? If it's been changed, how can I achieve it now?

I'm very grateful for any help!

Hi, A few weeks ago, I wanted to sync my open Firefox tabs between my old laptop and my new one. I signed in to my Mozilla account on both computers, and the sync process worked just fine. For weeks, my synced tabs appeared in my Firefox sidebar on my new laptop, and all was good. However, the other day, I had to restart my computer a few times, and when I open Firefox again, my synced tabs were gone. On my Mozilla account page, it still says that I am signed in to my old laptop. How can I see my synced tabs again? Thank you very much for your help!

I'm unsure if this is a Firefox Mobile issue (since the site's login pop-up works just fine on my laptop that I also use FF on), or an issue with the website itself, but I've already emailed the site about it and got no response yet. So, figured I'd try here. Also, I just tried re-enabling Chrome to truly see if this is browser or app related and sadly this works on Chrome's Mobile but not FF's.

On the mobile and desktop version of this site: thingstogetme.com

There's an option to login with Facebook or Apple ID. The Apple ID pop-up works fine, but the Facebook one does not. Again, this is only an issue on Mobile. The Facebook option will turn a darker blue once you tap on it, indicating it's been selected, but nothing will happen. If you tap the page, it'll go back to its regular, un-selected blue.

I've turned off uBlock Origin, switched between mobile and desktop pages, refreshed, nothing works for this problem. Thus this essentially soft-locks me out of this site unless I use my laptop.
