Diễn đàn hỗ trợ Firefox

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

Many pages in firefox become unresponsive for me while loading and then appear to never finish loading. The address bar remains mostly functional, but:

• the page itself responds to no clicks or scrolls
• the favicon in the tabs above the address bar is replaced with an animated loading icon and stays that way
• the refresh button to the left of the address bar becomes an X and stays that way
• the cursor icon becomes stuck (e.g. if it was a pointer, it remains a pointer no matter where on the page I move it.)

One example page where this happens is the firefox 'Get community support' forums page itself which loads when I click 'ask now': https://support.mozilla.org/en-US/kb/get-community-support?exit_aaq=1

What's particular about my setup?

I have produced this behaviour when having no browser extensions at all, not even my password manager. I'm using firefox on Linux (Ubuntu 22.04 LTS). I found that on Ubuntu 22.04 LTS, it comes installed as a snap even if I install it with `apt install firefox`, and I really needed a non-snap implementation so that I could integrate my password manager. (I'm using 1Password. To integrate the 1Password browser extension with the 1Password desktop application, I can't have firefox sandboxed by snap.) Therefore, I installed firefox as a deb package using the instructions given on https://www.omgubuntu.co.uk/2022/04/how-to-install-firefox-deb-apt-ubuntu-22-04:

```

1. remove the Firefox Snap:

sudo snap remove firefox

1. add the Mozilla Team PPA to your list of software sources:

sudo add-apt-repository ppa:mozillateam/ppa

1. tell apt to prefer the PPA/deb/apt version of Firefox:

echo ' Package: * Pin: release o=LP-PPA-mozillateam Pin-Priority: 1001 ' | sudo tee /etc/apt/preferences.d/mozilla-firefox

1. tell apt to install future upgrades automatically

echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox

1. install the Firefox deb using apt:

sudo apt install firefox ```

Is there a better course of action? Having this password-manager integration is essential to me.

if firefox is present on my computer it allows roboform to open websites but will not allow login to be completed even in microsoft edge or firefox If firefox is removed roboform works fine in microsoft I have uninstalled firefox several times and reinstalled to no effect including roboform as a FF extension

I am seeing a very odd behavior. Sometimes, not always, it takes two or sometimes even three clicks to go to a link, especially bookmarks for some reason. That and at times I have to click on the address bar and hit enter even if I clicked a link to go to a new site. Mostly this happens with bookmarks and history items, but not always. I have disabled hardware acceleration and my few add-ons, I even put Firefox into safe mode to try to diagnose the issue further. Unfortunately I'm still lost and the issue presists. Any thoughts?

I'm using macOS Sonoma 14.1.2 and Firefox was just installed yesterday 120.0.1. The only extensions I have are AdGuard and 1Password.

I have noticed that when it occurs, I see the reload button cycle between the X and the Reload icon for like half a second and then does nothing else until I click on it. I have checked my Internet connection and it has been stable.

I have had many recent issues accessing things with Firefox. A couple examples are Slack and NEUP.gov. If I try to go to NEUP.gov it never loads. If i try to log into the University of Michigan enterprise Slack, via SSO, it says 400 Bad Request.

Both of these work fine if I do them on Chrome. I also talked to Slack, and they suggested it is not on their end. I don't want to switch to Chrome, but if I can't access the sites I need to on Firefox what else can I do? Any ideas on why this is happening would be appreciated.

I have some issue with spacebar on some sites with firefox. like in google search, the spacebar refuse to display two or more blank space in a row when the bar is pressed more than once. instead each press is added in the same blank space. means for example if i press space 4 times, only one space appear, but to delete that single blank space i need to press the "back space" key 4 times.

Similar problem with the search bar on the cookie setting (the page in preference where you can manage or delete your cookie list). several time the search bar doesn't write the letters i type. But copy/paste a text work, only keyboard doesn't work. I need to close and re-open the tab for the keyboard working again on the cookie list search bar.

Firefox use a lot of CPU time ( it reaches 100% ) while watching youtube videos in 720p on Windows 10, and videos lags and stutters too much. Not using any ad blockers, non of plug-ins are on. It does work just fine on Ubuntu on the same machine Vids also were working fine on previous popular web browser known for its spyware

Using hardware acceleration is on in browser settings. Specs are: CPU: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz 4,00 GB x64 Windows 10 Home edition 22H2 GPU: NVIDIA GeForce GT 635M

Firefox version 120.0.1 (64-bit), up-to-date

Hello,

I've just downloaded firefox, making the switch from chrome. Doing so I've migrated a couple of tabs and extensions I had. Totally it was 50 tabs, with 6 extensions, I've downgraded now with the switch and it's only 37 tabs and 2 extensions, even so firefox is using more ram than google by a large amount. With 50 tabs open, chrome was using 1.5gigabytes of memory. With the same 37 tabs and extensions, firefox is currently using 6 gigabytes of memory.

The tabs used are from reputable sources, so firefox shouldn't be breaking on these websites. The extensions I am using at the moment on firefox is, Ublock origin, Dark Reader.

As far as reputation goes, firefox should be using less Ram than chrome. Is there a setting I should know about to lower such performance issues? Firefox acceleration is ON.

Thank you for any answers.

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

Immediately on update to 96.0 this afternoon, multiple sites failed to load - Google(Maps, News etc), Yahoo, Flightradar24 etc - others partially loaded - then sat there blank. Explanation of errors is NOT clear -

Is it possible to revert to previous version? Everything seems to work fine when using EDGE!

I was watching anime today on some site and my firefox was downloading many files without my knowledge into my download folder. I'm worried that it can be some viruses? This is a screenshoot. Should i be worried? Thank you for help.

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

Respectfully, Don

Whenever I attempt to access DRM content such as netflix or spotify I am notified that the WidevineCdm plugin has crashed. I'm running firefox version 101.0.1 on Kubuntu 22.04, I am running the debian package release, but I had this issue with the snap version too. I've submitted crash reports, but they're all "EMPTY: no crashing thread" (https://crash-stats.mozilla.org/report/index/20af09a5-6bc4-4719-9242-38f5c0220614 here's one).

Hi, so my problem was exist for several times both on my PC and laptop and can't figure it out keyword to fix my issue and tbh i don't know what trigger this behavior. When browsing sometimes came situation can't type anything using my keyboard, even when outside firefox.

my current workaround to encounter this, i just need open any web with place I can type like search bar or text box and type there then back to normal (so I guessing it's maybe related to when I open web with this kind search box then move to other tab it's stuck on that box? but i can't make sure, it just happen randomly but often). and I don't know if this issues related to windows or just firefox because I didn't know the trigger so i can't recreate this on other browser.

If anyone know how to fix this, please help me.

thanks in advance

I had the same problem like the link below when I use firefox.

https://www.reddit.com/r/firefox/comments/tjxh7s/videos_freeze_when_window_isnt_in_focus/

So, did what the instruction says and it solved the problem regarding discord.

But, since I changed that setting, firefox doesn't remember my google login or dark skin settings of other websites (it was always automatically logged in when I use YouTube. Not like it remembers the password).

How can I solve it? I resetted firefox multiple times.

I'm on Ubuntu 22.04 which is using the snap package of Firefox.

It seems that I cannot open local files in the /tmp directory. When I place a test.html file there and run `firefox /tmp/test.html`, it returns a file not found error. Why?

I don't have the problem with files in my home directory.
