Every time I have to restart the microsoft nightmare called windows 10, the 1st time I open Firefox it opens in a half screen window on the right side of my screen. It's set to open maximized and run as administrator but still won't do so immediately after a restart. Is there a fix for this?

Hey, I just recently started using Firefox, and I've started to notice some odd behavior. When watching videos and reels on Facebook (Desktop version), videos will flip-flop between normal and really bright and washed-out. I'm currently on Firefox 130.0 on Windows 11, and I always have HDR on. The imagery is silly, but these two screenshots (using win-shift-s) are from the same video only seconds apart, and this happens on almost all of them. Not yet tested to see if it also happens on Youtube or Twitter videos.

Hello all, I recently made the change from chrome to firefox and have been loving it so far. The only issue is; when I have a youtube video open while playing minecraft, the video lags and the audio skips. It never buffers and I have a great fibre Ethernet connection. When I try on chrome it doesn't happen. Only on firefox.

About a month ago, firefox stopped remembering a download location, it's only on one website though. I can download from anywhere but there and it remembers the location but it won't from that site and that's where I download from the most.

This was ALSO occurring BEFORE I switched to ESR, in both types of windows (Private & Standard):

A click to open a website link results in Firefox doing a runaway, unstoppable, rapid opening of tab after tab after tab. The only way I have found to stop it is to close Firefox entirely, losing the tabs I was working with in addition to the runaway tab openings. Any solution?

Windows 11 Pro Firefox 128.2.0 ESR (also behaved in same way using standard release version, as well as ESR)

The amount of memory firefox takes is drastically higher (2GB + tabs and extensions) on Apple Silicon when compared to having the same tabs open on windows or linux.

When I look into the memory tree generated at `about:memory`, it seems that the `heap` is allocated nearly 1.5GB.

I am just a computer science student at the moment but that seems unusual to me. Please find the attached memory-report.json.gz file here

I was enjoying using firefox. It has only been 2 days since installation after which it started lagging. It lags only while scrolling pdfs, youtube. All other animations are working fine. Only problem is in scrolling it.

I've been having an error message popping up that says that FireFox is already running in the background, like my account has been locked but none of the fixes, fixed the issues. I'm really appreciate any help you can give me. I've had to make this report from Microsoft Edge in the meantime. Hopefully this can be fixed because Firefox has always been my preferred browser.

even if one sets "dom.security.https_first_pbm" to false, among other settings, you get an error among the lines of: An error occurred during a connection to EXAMPLE.COM:5000. SSL received a record that exceeded the maximum permissible length.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG

what? why is this still worrying about certs, when I clearly want to open up a non-ssl port, that's ridiculous, I gotta disable cache or delete it for this to go away at the least, I can't be using ssl on all the ports, that's an absolute pain

how do you get around this? how do you stop firefox from rewriting a http request to https?

RTX VSR still doesn't work at all. I have version 130 of firefox and no VSR. I've tried it on chrome and no issues there, it just works. I've always enjoyed using firefox and it bugs me that apparently this feature was added in update 126. Moreover there is multiple threads giving advice on how to get it working, I've tried all the methods and even then still haven't been able to use VSR on firefox.

for me, about:profiles currently shows my profile in use as:

Profile: Joey This is the profile in use and it cannot be deleted. Default Profile yes Root Directory C:\Users\Joey\AppData\Roaming\Mozilla\Firefox\Profiles\7agyzsl4.Joey 10 Local Directory C:\Users\Joey\AppData\Local\Mozilla\Firefox\Profiles\7agyzsl4.Joey 10 1. why does it say "Profile: Joey" when the profile filename is "Joey 10"?

2. I want it to say "Profile: Joey 10", or for that value to MATCH the filename of the root or local directory.

    What do I need to do?

I tried to download something from this website https://www.maxon.net/en/article/stamp-your-footage-onto-any-3d-solid?srsltid=AfmBOoqo9m0rrsDYUvZzXpyTs1uLPotn8tBr03C5c9iLl7mydQIP3AVM and told Firefox to save it to my dropbox desktop app. Some weird warning popped up about the fire path being invalid or something like that. So now when I go back and tryto choose a different download location, it wont download at all. I definitely remember having this same exact issue months ago and don't remember the solution. please help

Recently I found I can't view video clips on MSN, white rotating circle around Play button. U tube videos are no problem. I can view video clips on Safari, but Firefox is my preference. I have an Imac running Sonoma 14.6.1

I think Firefox used to be the best browser on the planet. However lately: Firefox has been randomly shutting down. Usually while I'm typing a comment or a reply to some comment.

Just tonight, I tried to buy a box of Bibles from the Gideons International, and when I clicked the Place Order button, nothing happened. I started the crappy Chrome browser, went to the Gideon website and created an order. When I clicked Place Order, it 'thought' for a few seconds and then said "Order Complete".

Quite often, when I click on a link, I receive a message telling me Firefox cannot connect to that site. Again, if I use Chrome, or even Brave, the link goes right through.

Months ago, I never had these problems. Are you people in the business of screwing up the best browser ever invented? Put Firefox back like it was when it worked.

SINCE FIREFOX IS MY BROWSER, HOW DO I PREVENT CERTAIN GAMES FROM TAKING CONTROL OF MY MOUSE ? I HATE IT WHEN THEY SLOW MY MOUSE DOWN OR WON'T LET ME MOVE,SOMETIMES IT CAUSES ME TO LOSE THE GAMES, VERY FRUSTRATING

For some reason, about a week ago, Firefox started lagging BADLY when saving any file. It will take like 20 seconds to load the "save as" popup and then, once saved and it closes, takes another 5 seconds to regain control and not make the error sound when I click.

Firefox loads quickly on every other aspect. And I have a beast of a laptop. It has an Intel Core i9 13th Gen 13900HX, 64GB of DDR5/6 RAM and a Nvidia RTX 4090 Laptop graphics chip. It also has Windows 11 Home. So it SHOULDN'T be this laggy. And I refreshed Firefox multiple times and even reinstalled it. NOTHING!

And, while I'm personally not complaining about the icons in the bar looking like they're from Windows 7 or something, I wonder if it's connected? Regardless, I NEED this fixed as it's damn near unusable for me. I'm in college for video game development, so things like this are the last thing I want to deal with...

I am having an issue with my new OLED monitor and GPU where Firefox is not able to correctly display the color of icons and various other sites and images correctly. I know this issue is directly related to firefox because every other browser and game or anything I use works perfectly in terms of color accuracy. Firefox is unable to be fixed. I have already tried changing the color settings within firefox many times and that has not helped. I have also already tried refreshing Firefox, completely uninstalling and reinstalling firefox among other things. So far there seems to be no fix. I have tried restarting my computer as well. The issue is persistent. I have attached an image of what it looks like compared to a reference of what it should be like.
