Firefox Community Forum

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?

System: Linux/Fedora41 Firefox: 136.0.4 Monitor: Acer 27" 1920x1080

When I open a FF window, it opens full screen vertically and to some width horizontally, both dimensions not desired. My usual style (for the MANY years I have used FF and Linux) is to use a FF window that is NOT full screen in either dimension since I normally have multiple windows open simultaneously. This FF behavior has started just recently.

This behavior occurs when starting FF from the FF icon on the desktop, when opening a new window from the FF main menu, or when opening a new window via the 'Open Link in New Window". (Perhaps other ways as well: these are those I encountered.)

I have tried: .... Opening FF/resize window to desired size/close FF using 'Quit': no change on restart .... Deleting the xulstore.json in the profile folder/restarting FF: no change on restart

I would like to restore FF to its previous action: open new windows at the same size as the last one referenced. Can someone help?

Thanks.

I am looking for a way to adjust the settings, or really anything else, in a way that would result in the site being displayed like it should be because it is a rather integral part of the game and I really don't know where else to look anymore. Now, I suspect that it's because I switched to Ubuntu because I've never had this issue with Firefox while I still used Windows, but I really hope there's a way to resolve this. That being said, it seems to be specific to Firefox for Ubuntu because the colors show up in the menu when I use Opera on the same OS.

The four images I've added should show what I'm talking about (I really don't have a way to phrase this any better, sorry) and I really want Firefox to display the drop down menu like it is supposed to look: the colors themselves underneath the text. (it looks like Firefox on mobile now if that is any help in figuring out where to start, but I don't see why it would fail to show the site correctly on desktop)

The part of the site in the first two pictures is accessible without an account: Scrying Workshop

Edit: It occurs to me that I probably should list what I've tried already. - disabled enhanced tracking protection - checked my settings (colors are not overwritten) - tried it with a new profile - disabled all extensions - reinstalled Firefox

Multi-Account Tab is on longer loading. I uninstalled it, shutdown my computer, and restarted it, reloaded it back on. Unfortunately, it's still not working. I do have Tab Stash on my computer as well, and it not working either. I guess the two problems are related, but I thought I would start with Multi-Account because I didn't want to lose all my bookmarks.

Does anyone have any thoughts on how it fit this?

Thanks,

For some reason text rendered in canvases (used by Minecraft hostings to display console) is distorted. I'm not getting this behavior in other browsers (including Zen – Firefox fork). The issue persists in both stable and nightly versions, with and without hardware acceleration, in safe mode too. Any clues?

Recently, my bookmarks have disappeared (but leaving empty folders), reappeared, or reappeared but incompletely. (incompletely meaning not all showed up - alphabetically, only bookmarks beginning through letter "D." When I search bookmarks, the "missing ones" show-up in the results; they are just not visible in the toolbar. Similarly, if I try to add a new bookmark, it does not show. Help! thanks

I've been using Firefox and Gmail on my PC and android phone for years. Today I can't log into my gmail account on my PC and instead it redirects to google support and goes on about clearing cache etc etc. I have cleared the cache but no different. I have restarted my pc and no different. PC is Windows 10.

I can log in to gmail using Google Chrome so I can't see that it is a Google problem. I can also log in ok on my Android phone.

Is this a Firefox issue?

So basically, I'm trying to add a 2FA code, homever when I scanned the code using google authenticator, everything went normal. Homever, when I try to put in the code, firefox only lets me put 5 digits but not 6. Any solutions?

I get this dozens of times in a session. As far as I can tell it doesn't affect performance. I found a solution about using notification-daemon for Ubuntu from 4 years ago that doesn't apply to Slackware. I like to eliminate error reports. I don't even know what this means. Knowing would be great, even if I can't stop it. Just eliminating the error report, if it's harmless, would be nice.

please forgive me for asking again, but I REALLY need my addons to work. Firefox disabled my addons, forcing me to upgrade to a version of firefox that I don't need, since the old one was working just fine. The new version does not seem to appear to have downloaded properly, and neither version is allowing my addons to work or be re-installed. Please explain it to me like I am 5 years old, and help me to get this fixed without losing any of my info that might be stored in the addons.

 Thank you.

During what I assume are high bitrate sections of YouTube videos (e.g. lots of movement, high resolution) YouTube will constantly drop frames.

Video for example: https://www.youtube.com/watch?v=KLuTLF3x9sA

I have tried: • Safe Mode • Installing the Flatpak and testing in that, which also has a fresh profile as I don't use the Flatpak version • Testing different related about:config settings – I can't remember them all now, but I tested every one I found googling that is related to the issue or hardware acceleration.

Hardware acceleration is for sure working. Turning it off makes the video drop to one or two FPS.

Chromium has no problem with the same video. However, you can see from the screenshots that both read the resolution/scaling of my screen differently, and it implies that Firefox is rendering something like 6314 x 3552 while Chromium is rendering at UHD, the resolution of the screen and my video. If I turn off all my Global Scaling, Firefox stops dropping frames (the same info box on YouTube states resolution is UHD), reinforcing my theory about scaling being the issue. Both are confirmed to be using native Wayland.

Since last two updates, I noted I can't click on the URL field or any icons next to each other two versions ago. I changed the Bluetooth mouse to a lined mouse, then it went OK. But with the latest update, again, the same symptom occured and persists: I am on MacBookPro, so I manage to Command+any command key.

How can I restore and click on URL field, copy URL, or reload the URL address again? OF course, I need to use other icons for each function.

Why is there a setting that doesn't do [expletive]? Picture-in-picture can't be disabled through settings or about:config..... So how the living [expletive] do I disable [expletive] buggy [expletive]? And how the [expletive] do I set it to continue playing even after closing the small picture? Why is there no [expletive] setting for this while you have a setting that doesn't do [expletive]?
