Firefox 技術支援討論區

I am having trouble to open firefox browser for ubuntu 20.04(focal). I have also delete mozilla folder from cache and then reinstalled again. I have tried to rename profileini file. Finally I have uninstall and install using terminal by "sudo apt install firefox" but still I am getting this error "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

How to resolve this.

Thanks in advance.

When browning some site will cause a Firefox to freeze, all UI stops working, if I try and reload the page nothing will load and if I try and close and reopen Firefox I get a zombie process that last for about a minute. Obviously this is with no ad dons or hardware acceleration and nothing is listed at about:crashes. The only useful tip I have comes from the command prompt. First when the freeze is first triggered I get the errors ``` MESA: error: Failed to query drm device. libEGL warning: egl: failed to create dri2 screen MESA: error: Failed to query drm device. libEGL warning: egl: failed to create dri2 screen ``` and when I try and open it after a freeze and there is still a zombie Processes ``` [Parent 111218, IPC I/O Parent] WARNING: process 111455 exited on signal 15: file /build/firefox-RH6krf/firefox-115.0+build2/ipc/chromium/src/base/process_util_posix.cc:264

``` and finally when it kills the zombie processes ``` RunWatchdog: Mainthread nested event loops during hang:

--- CanvasManagerParent::Shutdown

ExceptionHandler::GenerateDump cloned child 111871 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... ``` the included images are what pops up when trying to open Firefox when it still has a zombie processes and when it kills the process

On Ubuntu, drag and drop has broken for me. My mouse cursor does not seem to react to different types of content, like hovering over links. My main problem is that if I highlight a piece of text, or some other content block on a page, and drag it, it does not work as smoothly as it should.

Has anyone else experienced this recently?

I find closing Firefox helps temporarily but within 10-15 minutes the same problem occurs.

I have re-installed Firefox and I am running the latest version. I haven't experienced the problem in Safe Mode.

It only occurs on Firefox and is browser-wide.

I'm a Chinese user, and all my firefox account in other devices( windows10, IOS) was login in page https://accounts.firefox.com.cn", but using firefox in ubuntu, it was redirect to https://accounts.firefox.com. Even i login with the same e-mail, the data can not be syn, and i have known the reason was there are two different server for Chinese.

But i need a way to syn data in Ubuntu, please tell me how to deal with that. 3Q !

Firefox will no longer display the main window. I get an icon in my taskbar but the window is nowhere to be found. I've tried the tricks of maximizing it and moving it but neither works. I have found that if I locate the xulstore.json file it will work but only for a short time. Next time I start Firefox I get an icon but no window. Very frustrating!

The sulstore.json file contains nothing that suspicious:

``` {"chrome://browser/content/browser.xhtml":{"main-window":{"screenX":"2129","screenY":"777","width":"1280","height":"1040","sizemode":"maximized"},"sidebar-box":{"sidebarcommand":"","style":""},"sidebar-title":{"value":""}}} ```

If I start Firefox and right-click the icon, select maximize it's as if it's maximized covering all my windows but yet invisible. I can see my other windows but I cannot interact with them.

Deleting the xulstore.json file often fixes this but it breaks again shortly. What's the deal???
