Firefox Community Forum

I'm stumped. For years I kept Firefox on my Windows machine (Win10, 64bit, 8gb ram) at some level around 80x (I forget the number). I even recently switched over to Edge until I got fed up with its complicated design. So when I went back to Firefox, I upgraded to the latest 147.0.3 (64-bit). At first everything seemed okay. But then I noticed I was having trouble posting comments on any Washington Post comment section OR the whole thing would freeze up or other oddities. ONLY there. Everything else runs fine.

To add to the mystery, I walk upstairs to where I have a Mac (Sonoma, with 64gb ram) with Firefox 143.0.1. And I can post comments on the Washington Post, nothing freezes, everything works fine. So it can't be a problem on the Post's site itself.

Back on the Windows machine I have tried various Firefox settings, changing the permissions from strict to standard, changing the performance settings, turning Add ons off and on one by one, running in Safe Mode. But no changes change the problem on the Post comment section.

I'm at a loss to understand the difference. The Mac does have more Ram, but previous to my upgrade on the Windows machine, it was running the Post site just fine.

https://errors.edgesuite.net/18.acf7d517.1771548295.4f66cee0 is what I get when going to https:\goddady.com as of today. Running on Windows7 (no, I won't upgrade). Tried a variety of changes. But Chrome works fine. Any suggestions?

”Using my HP Notebook computer, BOOKMARKS (in Mozilla/Firefox): Who governs my access to my list, which disappeared on 2/20/2026. It looks like Google (i.e., Yahoo) has taken control of this function……….and, if I set up Sync on my computer, how will my current DEFAULT YAHOO EMAIL be impacted?”

Almost every time I open up Firefox it has a little pop-up under the tool bar asking "Open Firefox every time you restart your computer?", and every time I select "Not now", which I guess is intended as only a temporary answer. How can I permanently say "No" and keep this from popping up constantly?

I use Firefox daily for website management, analytics dashboards, and multiple browser-based tools. When running several tabs and extensions at the same time, I sometimes notice slower performance and increased memory usage.

I would appreciate guidance on: Recommended settings to optimize Firefox for performance Best practices for managing extensions efficiently Whether hardware acceleration should be enabled or disabled Any advanced settings that help improve stability The goal is to maintain smooth performance while working with multiple active tabs and web applications.

Thank you in advance for your support.

I reinstalled Windows and downloaded the browser again. I logged into my account, turned on synchronization, but none of the data was synced. I am absolutely sure that synchronization was enabled on my old browser. I tried turning it off and on again, but nothing helps. Please help me get my data back!

I had to remove the Recommended stories from the home page. every source was a left leaning outlet. How is someone supposed to get a balanced news snapshot if all the sources have the same biased tilt?

Pretty sure I've got a problem with a fake certificate / server: in ISRG Root X1. > R13 >. "interfaithpowerandlight.org". This is a legit and very good org, but it ain't no server. A notification pops up intermittently on both mac and iphone that it can't be verified, at which point I've been clicking on cancel. Suggestions, please and thank you?

Hi Team,

I’m currently conducting a DevOps training session and we are using Firefox to inspect headers for a web app running inside a local Docker container (localhost:8080).

We've noticed that occasionally the 'Network' tab in DevTools fails to show the full response headers for our nginx proxy, even after clearing the cache. It works fine in other browsers, but I prefer using Firefox for our students because of the superior CSS Grid and Flexbox tools.

Is there a specific setting in about:config that might be limiting the capture of headers for local loopback addresses?

Thanks for the help!

Firefox stopped working properly this morning. whenever i try and open a new tab firefox tries to get me to setup sync instead of going to the new website. I turned off sync. I do not want to sync with anything at this time. How can i get firefox to work again?
