Diễn đàn hỗ trợ Firefox

Pretty much title.

Since about two weeks when I open firefox the browser freezes every few minutes for 10-15 seconds. Launching firefox in Safe Mode or disabling all extensions didn't help. When I open Task Manager during freezes it shows that Firefox is "Not responding" and when I open sub-tasks it's usually one or two causing the problem. When I close those either firefox closes completely or youtube or reddit crashes, leading me to believe it's something with those sites? Refreshing or reinstalling firefox hasn't helped. I'm on Windows 10 (all updates installed) and Firefox 84.0.1 (x64) as of the time writing this.

I hope someone can help and suggest something. I would hate to switch to another browser, but the problem has become unbearable.

All PC's mentioned below are on the same router and LAN, and all are using Firefox 86 x64 on Windows 10.

I have been a Firefox user for many, many years (I started using browsers in the 90's, 'nuff said). But having recently reinstalled a PC, I found myself unable to initiate sync on the new Firefox install there. I kept getting the error "NetworkError when attempting to fetch resource." in a red box when I entered my password. Perplexed, I tried creating a support ticket on another of my PC's (let's call it #2) - same error there when trying to sign in to Firefox support! I then tried to use that browser to access my account by going to Account Settings -> Manage Account. I was met with a circle animation - and a completely blank webpage.

This post is being created from my third PC, where, for some odd reason, the Manage Account function actually works, and where I was also able to sign into support. I made a change to my bookmarks on PC/Firefox #2, to see if sync was still working - and it did come through to PC #3. After that, I was finally able to start a sync on PC #1 (the newly installed one).

But I am still unable to do anything with my account on PC #2. Can't sign in to support, can't access Manage Account. And this cannot be purely about the profile or installation, as the issue was affecting PC #1 as well.

It seems like Mozilla's account management is really wobbly, and my prime suspect is the shift to "Firefox Accounts" on the support pages recently. But I'm open to being proved wrong.

Just hoping someone out there can tell me what this issue is, and how I fix it. The fact that I was unable to sign in to my Firefox Account from a completely new Firefox install makes me very uncomfortable. And my primary PC (#2) is still unable to manage that account, or sign in to the support pages.

Thanks in advance.

Hello, I would like to know is it possible to see/check the history of synced devices on Firefox. In other words, is it possible to check whether somebody synced my Firefox with theirs without me knowing it or being aware that happening. In this specific case I know it happened 100% and I just need somehow to prove it ... Thank you!

Hello!

I’ve been having quite strange problem with Firefox for a few months since version 80.X on clean Windows 10 (reinstalled from scratch after secure erase; the latest 20H2 version with all updates installed). It’s worth to mention that I’ve been using Firefox like 15 years and never had an issue like this before.

Firefox just fills up system drive completely (50+GB to 0 bytes remaining) few times a day under active usage. It happens randomly and I can’t identify the reason. I also can’t find any actual files saved on disk because it seems to be related to NTFS cache. I’ve tried disabling the following settings with no success:

browser.cache.disk.enable cached-web-content_cached-web-content browser.cache.memory.enable browser.cache.disk.smart_size.enabled

And couldn’t find any solution unfortunately. I usually have 2 windows opened ("common" and private) with 10 to 30 tabs each which is not much at all for i7/16GB I believe. This problem is extremely annoying and seriously affects SSD life so I'd really appreciate if someone would help me to resolve it. Thanks in advance!
