Firefox 技術支援討論區

I've been using Firefox on all my computers for a long time (Windows 10,) great browser.

However, starting today, specifically on my laptop, it's painfully slow (60 seconds to load Google) and very high CPU usage (over 20%.) It regularly stops responding to mouse and keyboard input. I have to kill it with Task Manager. Everything else on the laptop seems fine. I haven't made any changes I'm aware of that could cause this.

As an example, it took over 2 minutes to load this particular page, then at least another 90 seconds before I could type anything into it. My network connection is fine. IE and Edge work OK.

I've tried a Firefox refresh, no change.

An uninstall and reinstall, no change. I've tried a reinstall with also deleting all the appdata folders (so a clean install, no extensions,) no luck.

I've tried disabling antivirus (Symantec, always suspect) no change.

Unless there's something I can remove in the registry I'm at a loss.

I'm really hoping I don't need to switch to Chrome, or God forbid, Edge.

Nice to meet you. I tried to enable the start of Mozilla Maintenance Service, I get an error saying "The fiction is wrong". Looking at the properties, the downloaded Mozilla Maintenance Service is x86. How do I get Mozilla Maintenance Service x 64?

Win 10 HOME 64bit system OS: 19041.508 is.

Hi, I've been having this issue for a few months now, and it can get really annoying. Like the title says, the right side of Firefox is cut off a little for me, both in fullscreen and windowed fullscreen. This problem occurs on all websites, and is only fixed when I restart in safe mode, though I don't think any extensions that I have could be causing this problem. Any ideas would be much appreciated.

Thanks!
