Frequent browser crashes on the VK website when viewing content. What is it and how to solve this problem? Drop a message: https://crash-stats.mozilla.org/report/index/8b7a6415-dc8a-43ac-a0fe-e1d780231126#tab-details

Hello,

I have been using Firefox Mozilla for many years. This morning it opened up fine. Then this afternoon (Dec 7, 2023) it would not open for me and when I try to open a new tab it says that it crashed.

I looked and I do have Firefox as my start up browser in my settings. Thank you for any advice on getting back to my favorite browser.

Sincerely, Sandy

Since snap firefox keeps crashing somehow, it just hangs.. i cleared cache and all, reinstalled it, but still.. ?

They say linux is a broken system (:

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

As of yesterday when I was running v119.0 I was able to screen capture streaming content from Hulu/Netflix etc, this morning after upgrading to v120.0 overnight, that capability is now lost. Video and still captures are just a black screen. Please fix!

I use Firefox for Mac. Often when I want to click on a link or complete an on-line form, a long list of unwanted suggestions pops up and orevents me doing this. Only by hitting Escape can I get control back.

By the way, I don't want any solution which involves clearing the cache, as I value that help.

Hi,

I'm getting errors when trying to make online card payments with Firefox. Things like, Invalid card number, not being able to type number in box provided, (No Cursor). It works ok on some sites but not others. However, if I switch to the Edge browser all transactions work perfectly. This has been happening for some time (Windows 11). I'm thinking this could be a bug but not sure.

I have just reinstalled windows and then Firefox. If I click settings then a menu item it just freezes.

I have uninstalled and reinstalled.

Using Windows 11 Pro 22H2.

Any suggestions?

firefox has fully stoped working for me, i cant open even one tab a message appears that says' guh your tab has crashed' i cant do absolutely anything, please i need help

Firefox uses too much memory, sometimes 20GB on a 32GB Windows machine. It's usually one or two threads which are hogging incredible amounts of memory. This time I had about 30 tabs open.

Today I tried Firefox about:memory "Minimize Memory Usage" several times, and it was largely ineffective.

I did a "create memory dump file" of one 5+GB bloated thread using task manager, but can't find a way to upload the compressed archive with this report for analysis. Finding a way to report this issue was quite a challenge. It seems most help avenues are now missing/moved, and other reports of this type of issue are "Archived".

I tried killing the 2 bloated Firefox threads and checked for tabs which might be missing or malfunctioning. Everything continued to run normally while more than 10GB of memory was returned to system use. Leaving these bloated threads overnight doesn't improve anything, in fact I can often get up and find my machine is completely out of memory because Firefox consumed it all. My smallest machines have 16GB RAM.

These memory issues aren't new. I've been reporting them off and on for more than a decade. They get better for a few months after reporting, then they get bad again in a few more months. The battle to get memory leaks fixed is continuous while Firefox springs more leaks.

I'd like to give you the memory image I generated so you'll at least have some real data to look at and analyze for this report.

The attached task manager snapshot image is a very minor example of this issue. The numbers keep increasing like there are one or more large memory leaks.

"I've been experiencing an issue with Mozilla Firefox where it doesn't display the Silver Taxi Sydney Silver Taxi Sydney website correctly. Other websites seem to load fine, so I'm wondering if anyone else in the community has encountered similar problems with specific websites on Firefox. Are there any known compatibility issues or common solutions that could help resolve this problem? Your insights would be greatly appreciated!"

I have been using Firefox to log into the Social Security site for years. Today, I am unable to log in, after trying several approaches. I switched to Chrome and was able to log in immediately. What has changed in Firefox?

Unrelated issue. On this page is an option to "share data." When I tried it, nothing showed up, but there was a link to explain how to do it manually. When I went back to this page, it was blank, and I had to start over again. Not good website design!

Audio/Video frequently goes out of sync. I can fix it by exiting FF and restarting it, but this is annoying because it usually has to be done one or more times every day.

I am running Windows 10 Pro on a PC Firefox 120.0.1 (64-bit) Thanks for your assistance.

I am using Windows 7 and Firefox 115.5. When I close Firefox, it stalls and after a minute I get an error message saying Windows Explorer is hung up. Then if I can get an option to close the program. I have tried many ways to exit Firefox but nothing helps this. Thanks.

I am using Firefox version 119.0.1 (64-bit) on Ubuntu 22.04. Using this version of Firefox, as well as previous versions for the last few months, I am having a persistent error when using Google Advanced Search. I enter search criteria into the field “Find pages with … all these words” and successfully progress through a chain of web pages. Previously I was able to backtrack to the previously mentioned field and find my search criteria, then edit the text, and carry out a modified search. For many months this field has been blank when returning to it. So it is now necessary to re-enter all text for a new search. This is very frustrating. I have experienced this problem on the three computers that I regularly use.

I have found that when I use the Google Chrome browser the problem goes away and searches progress normally. I would much prefer to use Firefox as my browser as I find its bookmark system superior. The truth is that if this problem with Firefox can’t be fixed soon I will be forced to migrate to Chrome. Can you please help me resolve this Firefox problem?
