Firefox Community Forum

Hi everyone, I've looked for help but can't seem to find what works. I went to about:config and searched for toolkit.winRegisterApplicationRestart and made it false, it worked for less than a week and now firefox is starting when the computer boots up. How do i stop this? I'm using windows 11 24h2. I've been using firefox for years. My computer boots up faster than my router and it keeps saying i don't have internet. I'd appreciate any help thanks.

From last 2 days the website's specific product page https://hassan-brothers.ae/product/thermal-rolls-80-x-80mm-receipt-paper-48gsm/ continuously showing "refused to connect". as a developer I had to manage and add products for my client but unfortunately this problem occurs. I contacted to the hosting provider they said "I think some kind of sql query issue" after working on SQL it's working on other's end but still I unable to access.

Kindly resolve my issue thank you. I urgently need this.

I ran the windows 11 system file checker (sfc/scannow) to fix a font problem I was having. It did say that problems were found and fixed and I do not seem to have that problem any more. After that, i could not access the Settings in Firefox. I uninstalled and reinstalled Firefox and still could not access Settings. I also cannot access any Web sites either by typing them into the address bar or using bookmarks. Both Chrome and MS Edge work.

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.

I am one of those old-fashioned guys who has a title bar on the main window, and inside this (from top to bottom) a menu bar (File/Edit/View etc), then the current set of tabs, then the address bar.

I can click in the address bar and the caret appears, but the moment I start to type anything to edit the URL the address bar jumps up to to the top of the window, covering up the menus and tabs, with a menu of suggested URLs that at times covers most of the rest of the screen. Some images attached to show what I mean.

This started in a recent-ish release -- it didn't use to do this.

How can I prevent this behaviour, so I can just edit a URL in place the way I used to without the address bar jumping to the top of the window?

Currently using FF 135.0 (64-bit), Windows 11.

Hello, I'm having an issue with how Firefox is displaying images on some of our product pages. The image appears to be zoomed in which cuts off the side of the product image. The exact same product page displays completely fine when using Safari and Chrome. I cannot figure out the issue. Please see attached images.

I have tried:

modifying the about:config page prefs:

   browser.enable_automatic_image_resizing
   browser.enable_click_image_resizing 

I have also tried resetting the zoom features (Command/Conrl +/-/0).

I have also tried reinstalling firefox and running the browser without any extensions.

None of these worked. Any suggestions?

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.

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.

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

I currently use firefox 133 (32 bit) on Windows 11. Every time my router resets (either due to power outage or xfinity server outage) firefox fails to connect to multiple websites after internet service resumes, for example, I cant get to twitter.com (x.com) or even the mozilla support page while on firefox. Screenshots of the error and associated stuff are in the attachments. Firefox currently can't even check for updates.

All the webpages that do not work firefox due to the issues highlighted in the screenshots load perfectly fine in other browsers like chrome and edge. These issues in firefox go away after a couple days without any intervention which I explains how I was able to use firefox for these webpages prior to my last network outage and have still not been able to solve this post network-outage issue.

Things I have tried so far: - Disabling proxy in firefox: Did not work so I re-enabled it since that is how it was before the issues happened. - Re-install firefox 133: Downloaded an installer from chrome to do this but this also did not fix the issue. Note that I first downloaded the mini installer which downloads files as part of the installation and that also failed to connect to mozilla. So I downloaded the full installer. - Cleared cookies and data: did not work - DNS over HTTPS: Swicthed it off, did it did not work, so I switched back to the default setting. - Logged in to the router from firefox using the router's IP address: Not sure why I thought this would work but it did not.

Any help would be appreciated to solve this issue once and for all.

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?

My Firefox now only opens to a partial page size, not full, even though I click to a full page and then close out.

Opening again just goes to a reduced size page.

I have backed up my profile, uninstalled Firefox and reinstalled and brought my profile back in.

Still the same problem.

I think there is a file that controls this that is corrupted.

Need help.

I have sound in Windows, but YouTube is dead quit. I have tried all that is suggested in Firefox help and some YouTube sites. Nothing worked. I have tried off the computer and restarted, but no change. My system is Windows 11, sound works, and the latest Firefox update installed. Question is this a YouTube tacit to stop NoScript and uBlock?
