I have recently been suffering an issue where the browser becomes unresponsive and consumes massive amounts of hardware resources especially memory, in one case was using over 60 gigabytes of combined physical and virtual memory.

I have tried refreshing with Firefox Refresh, reinstalling and the problem still persists.

I believe it is either one of the addons Tree Style Tabs, but I don't know how to accurately diagnose this though, as sometimes I am able to get to the about:addons and disable one or the other but the problem doesn't go away and in some cases escalates to freezing the whole process.

When the application does this, the currently selected pages still work say I have one open of the ABC news website, I can still scroll up and down, but if I click a link to another article or something, nothing happens, same applies if I try to do anything with the address bar, the history and suggestions pop up but the browser doesn't do anything even after I hit enter.

I'd like to try and find out what the program is doing during this state of unresponsiveness, I left it for a couple of hours last week to see if it could work itself out, turns out it couldn't and the system ran out of Ram and fell over. I'd like to know how to diagnose it, know what it's doing, what it's hung up on and if it's related to an addon, tell the creator about it.

I apologise if this is not the correct way to go about this, I have just run out of patience trying to fix this myself.

I've been using Firefox 63.0 for quite some time and had dozens of websites open. I referred to these websites frequently. After checking some emails this morning, I decided to RESTART my laptop. It turned out this was a HUGE mistake!! When I went to "Recent Items" as I usually do to find the Firefox link, the only version available was 70.0.1. Not only was 63.0 NOT in "Recent Items" I could no longer find it in my Download logs. I had chosen NOT to begin using version 70.0 because there was no mechanism to move my open site from 63.0 to 70.0. HOW DO I FIND AND OPEN 63.0 OR, ALTERNATIVELY, GET 70.0 TO FIND AND RETAIN THOSE SITES I HAD ON MY 63.0? I should note that ALL MY PASSWORDS where required were stored on the 63.0 browser and are NOT present when I use the 70.0 version!!

When I last opened Firefox and entered a website, it did not load at first. Instead there was a message about OpenResty being installed or running. Since then there has been no other issue.

What is OpenResty, should it be running on Firefox? Do I have a problem.

I run the current version, with Adblock Plus, Duck Duck Go, and Facebook Container extensions.

I use the washingtonpost.com website multiple times daily. I just went to that site. Instead of the WAPO, the site opened to openresty.com. Openresty.com has replaced my Washington Post site and shortcut -- but ONLY in Firefox. The Washington Post site is up and running. I can reach the WAPO in Chrome on the same computer, my son can reach it in Safari and Chrome on his computer. I don't know how to get rid of this or if it is a threat. Thanks.

Hi

I'm an Computer Vision engineer and I migrated from Chrome recently.

The problem is, when I train a neural network and GPU utilization goes beyond 90% Firefox becomes unusable and sometime freeze my whole PC entirely.

I'm not even talking about YouTube or video sites, just new tab is enough to cause problem.

This never happen in Chrome and I'm forced to keep using it every time I need to use GPU.

Is there any tip for this?

I realise that Firefox uses up a lot of Memory (particularly as it tries to run each Tab separately). However, my Firefox seems to keep increasing its usage!

I can start with a number of Tabs open & (after refreshing each Tab - to ensure it is "lice" & "active") I will get (according to Windows Task Manager) about 1,300MB in use.

Without opening up any more Tabs & without trying to run any Web-Based Videos, over a period of a few hours it will increase & increase & increase - perhaps getting up to 4,000MB!

I've cross checked with "about:performance" (to open FF's own Task Manager), to show the individual Tab usage, & that NEVER totals up to anywhere near the figures shown by the Windows Task Manager!!

Obviously, my FF is fully up to date!

Any comments!

My firefox tabs has been crashing, and it has been getting far far worse. Practically none of the tab will open longer than 5 milliseconds. Other browsers works perfectly fine. I tried starting it on safe mode, no good. Tried clean reinstalling firefox, no good.

Can anyone help me why firefox is specifically crashing? About a month ago it worked perfectly fine.

I need help! Everyday I have at least 8 Chinese Hackers that show up on on the top in the list of websites visited on my Firefox. The entire page is in Chinese with Chinese pictures. Please see the attached images. I have no idea how long they have been there prior to being so bold to openly show themselves. I certainly have no idea of what they have uploaded or downloaded on my laptop. How can I get rid of them and what can i do to prevent them coming back? I know a lot of weird things have been going on in my computer that I have absolutely no reason nor explanation for. this has been going on for at least the last couple of years or more. I have had 3 computers to crash in a short period of time which I feel they have done. Spyware shows I have had a keylogger for a long time but all of the files it takes me to are protected and I have not been able to delete them. BillCowanjr@gmail.com

I have a sony vaio duo 13 which is a sliding laptop tablet hybrid. I run nightly on the desktop for all my web browsing because i guess i am what is called a power user. I need all the options and features that firefox gives us, and don't care for the barebones yet more fluid experience of the Metro app. My problem is that when I am using Nightly in Desktop it runs great, but anytime i close my screen (which doesnt close in the traditional sense, it folds the screen out) and transforms it into tablet mode, it launches the Metro version of Nightly. If i was using the desktop version it transfers all my tabs to the metro app. and when i open the screen to laptop mode, it simply closes everything. AFAIK i don't remember installing the Metro version... I can go to the Start Screen and find the metro app but i am afraid to uninstall it because i think it will uninstall the whole Nightly Application, which i dont want to happen. I created an administrator account and went to the MetroApp repository on the harddrive but there is nothing there related to nightly or firefox so i can't just delete it.

Hello everyone, I was happily using Firefox untill few days ago. Since then Firefox takes about five minutes to start (you cant see in taskbar or Application in task manager, just in Processes in task manager). When it finaly opens the first window it is not responding and there just blank window). It does the same in safe mode. I tried to reinstall it several time, with deleting every Firefox related files on computer (following every relevant instruction from Support). I tried to backup my profile and start with new one after reinstall. Every time with same result: Firefox works perfectly after reinstall (even when I transfer files from old profile, every bookmark is right), but when I restart computer the problem is back.

I checked PC for malware and viruses by Avast, there should be now collision with other software since I did not install anything recently. I have cleaned registres, cache and cookies with CCleaner.

I am running 64-bit Windows 7 Lenovo E430, everything worked perfectly for half a year. Only problem I can relate to is a warning message about low free space on system drive, which occured at the same time problems with Firefox started (but it is now even true, I have 5 GB of free space on system drive).

I found other unresolved topics, one of them with same system configuration as mine. https://support.mozilla.org/en-US/questions/956861?esab=a&as=aaq https://support.mozilla.org/cs/questions/958824

Any suggestions before I desperately change to Firefox Portable?
