What to Do When Firefox Keeps Crashing

Firefox is one of the leading browsers out there, giving Chrome a real run for its money, but that doesn’t mean that it is free from giving its users problems. One of the most annoying problems Firefox users complain about is browser crashes. Who wouldn’t find this issue annoying, especially when working on something important? When you have to deal with this problem, the following tips will guide you on what you can do when it happens.

Before you try any of the below tips, make sure to always keep the Firefox browser up to date. It’s always a good idea since it will certainly prevent your browser from crashing too often and will keep your browser up to date with the latest features.

After Firefox crashes, you should see the Mozilla Crash Reporter. This is a dialog box where you can tell Mozilla what has happened so they can do something about it (hopefully). If you would like Mozilla to contact you about the crash, remember to click on that option as well.

If you want to see the technical details of the crash, click on “Details.” You can add any further information here if you think that it will help Mozilla fix the issue. The more information you can provide the better.

It’s also a good idea to tell the company what page you were on when the crash occurred. That way they can see if the page you were on might have had something to do with the crash. If you choose “Restart Firefox,” and the crash happens again, there is a good chance that one of the windows or tabs you have opened is causing the crash. Select “Start New Session” and hopefully, Firefox will stop crashing.

When Firefox stops working, you can also try launching the browser in “Safe Mode” to see if an extension is the problem. You can start Firefox in Safe mode by pressing the “Shift” key while it is starting, or you can click on the “menu button – > Question Mark -> Restart with Add-Ons Disabled,

and select “Start in Safe Mode” on the popup window.

Firefox_Crashing_Safe_Mode

Use Firefox and see if the browser keeps crashing as it did before. If it doesn’t, an extension, hardware acceleration or theme is to blame.

If Firefox is still not stable even in Safe mode, the theme, hardware acceleration or the extensions are obviously not to blame. Mozilla suggests that you see the Firefox Hot Topics section to see if you can find a solution to your particular problem there.

If you were unable to find a solution, you could always try to get help by using your crash ID. You can do this by going into the Firefox location bar, typing about:crashes and tapping on Enter. You should see a page listing submitted crash reports. Locate the latest crash under Report ID, right-click and select “Open Link in New Tab.” You should see a tab that will lead you to a page on crash-stats.mozilla.com. When it has finished processing everything (Look for the words Your report is being processed), close the report tab.

Resetting Firefox can also be very useful since it gets rid of themes, extensions, site specific preferences and search engines. Why is this helpful? Because your information is stored in a profile folder, and sometimes there can be problems with that folder. By resetting Firefox, a new profile folder is created, but don’t worry – you still have your browser history, bookmarks, cookies, saved passwords and auto-fill.

To reset Firefox, click on the Menu button and go to “Question mark icon -> Troubleshooting Information.” In the page that loads, select “Refresh Firefox.”

Try reinstalling your favorite extensions one by one and see if they crash Firefox. If yes, then you will know which extension is the culprit. The same goes for the theme.

Trying to find the exact cause of a crash can be tough and may require the help of the experts over at Mozilla, but now you know what you can do when Firefox crashes. Does your Firefox browser crash often? Let us know in the comments.

  1. What O/S are you running that you have FF crash problems? Is it possible that it is the O/S that is causing the crashes?

    Over the past 10 years I have run FF on at least 10 different Linux distros and have had only occasional hiccups. Nothing that I would call a problem. I know I am only one person but if the problem is as widespread as you seem to imply, I would have had many more crashes.

    • Hi Dragonmouth,
      It´s difficult to determine what exactly is causing the problem, but unfortunately, it´s something that happens. How widespread it is, only Mozilla knows, but that´s good that you don´t have something you would a problem. =-)

      • I mentioned O/S as the cause because of the (in)famous directives supposedly issued by Microsoft upper management:
        “DOS ain’t done until Lotus won’t run”
        “Windows ain’t done until DR-DOS won’t run”

        It is possible that MS has code in Windows that interferes with Firefox running smoothly.

        • Hi Dragonmouth,
          It´s definitely a possibility that Windows could have a code that may interfere with Firefox, but if there was, I don´t see them changing or removing that particular code. They could just say, ¨Use another browser¨. =-)

    • Hi Brian,
      It´s good to hear that it doesn´t crash all the time and hopefully it will stay that way. =-)

  2. I’ve used FF in one “flavor” or another for the last 12 years..had lots of problems in 2004 with FF but i now use Comodo Ice Dragon…no problems what so ever! any problems i have with Ice Dragon aren’t browser related, it’s win 10 acting up….i’ve never liked IE and this “new” version of IE is just as bad if not worse in my opinion.
    I’ll just stick with C.I.D. till something much better comes along. open to suggestions!

  3. A large part of the problem isn’t the fault of firefox, it’s obnoxious and stupid website designers.

    Sites should be designed for standard HTML5 that will work on any HTML 5 browser. Instead, they design solely for their favourite browsers and write bad code that target other browsers.

    It’s the late 1990s all over again.

  4. Hi P Smith,
    I agree, some sites are not set up the way they should and it would certainly help if they were. =-)

  5. i play FV2 (FB games) and it keep crashing.. and why FF have a 1.5gb running plugins? it takes way to much for my PC.

  6. Recently – usually more than 5-7 times a day.
    After using your method – it’s much better.

  7. I’m thinking that it is probably something in Windows 7 and 10 because it’s been a major topic of conversation for everyone at my work here lately due to the fact that the IT department has just begun the process of discussing with the Board about just having it removed from all the computers so they would stop getting so many phone calls and repair tickets that are either about or caused by Firefox.

    Needless to say that the move started everyone talking and we’ve all been realizing that a lot more folks than anyone realized have been quietly switching to other browsers due to the instability both at home and here at work. Since most folks run either 7 or 10, general “gossip” is that it’s probably Windows itself and frankly, if that many people are encountering that many problems, I’m inclined to actually agree with the crowd for once.

  8. Hi DLister,
    Wow, Firefox is causing you that many issues?? I wouldn´t be surprised it Windows 7 or 10 had something to do with it. I use Firefox, but most of the time I´m a Chrome user. =-)

  9. Crashes every time I try to print with PrimoPDF. Been using that program for a long time, no problems. Have the latest. NOW FF is crashing even when I open a file! The crashing started just recently. If I could read the technical geek jargon in the Crash Reporter, I bet I could fix it myself. But how?

  10. Very rarely do I have a FF crash…in fact I can’t recall the last one. But recently Flash once again started crashing every time it’s opened, but only on a W7 32-bit machine. Absolutely no problem on two W7 64-bit machines, although all are set up the same way and FF is configured exactly the same for all three. The death of Flash cannot come too soon for me!

  11. I use FF it’s up to date, version 47. I started getting crashes on a daily basis about a month ago. I would say an average of 3 times a day it crashes. I do use multiple tabs, 2 are streaming as I am a stock trader in real time. It’s getting quite annoying. I use Win 7, and it’s up to date. No malware, no virus’.

  12. I’m getting crashes with Firefox daily for several days now. Everything disappears and I cannot open Firefox. Then when I use C Cleaner to clear the system, I’m told I can’t until Firefox is closed, which is odd, because I cannot access Firefox to close it, so I let C Cleaner force close Firefox. Any ideas?

  13. Not computer savvy at all. W10. FF crashing frequently for about 2 months. No one responds from FF when I comment. Tried that 2x. Reset. Get warning Adobe Flash plugin not properly installed. Reinstalled. Nothing working. Had no problems with FF on XP. Loved XP. Didn’t want to abandon it. Still have couple of computers that operate with XP and FF and doing okay although slow. Help!

  14. I’ve been using FireFox happily for years. Recently it’s been crashing 4 or 5 times a day. It crashes when I click Reader View, which I love. It’s great for de-cluttering the screen, getting rid of advertisements, and magnifying the screen to a comfortable level. It doesn’t always crash. Most of the time it works like it’s supposed to, but then, for no apparent reason, it crashes FireFox. If I then restart FireFox, either from the crash report screen, or just click the icon, everything works as normal for a while. Once in a while, if I leave the Reader View screen open for a while (phone call, went for a cup of coffee, etc), FireFox will have crashed when I get back. Very annoying.

  15. I’ve been using FireFox since it first came out. On the whole it’s been a great product but in the last year or so I’ve found it just too unstable. What I used to get was multiple crashes every day on different PCs and different versions of windows. I always used to send crash reports but it didn’t help. I chatted on the forums about it, with others looking at my crash dumps. No one could come up with anything that made any difference. Every day I’d get the same thing, the memory consumed by FireFox just kept rising until it crashed. I tend to keep a browser open all the time and keep my PC on 24/7. Some suggested I don’t do this and even don’t visit some of my regular web pages (like bbc.co.uk). Turning off features etc didn’t make any difference. Anyhow I changed to Chrome and since then (2 months now) I haven’t had a single problem. I use it in the same way. Same add-ons, same web pages etc. Not one problem. Some of the techies on the forums were suggesting that the problem was with the web pages I was visiting – bad Java or Html code. However, Chrome perfectly stable with the same web pages! The memory usage doesn’t run away.
