  Firefox crashes on opening a few seconds. That started everything suddenly a few weeks ago, and despite several attempts to every day, I still cannot load firefox application. It crashes immediately on startup every time anything and journalist accident happens. I studied all the articles and followed their suggestions. I installed the latest version of firefox and still get the same results. I can't even open firefox in safe mode.

  Heather, not sure I can help, I'm not a Mac user, but I'll have a look at the crashIDs that you provided.

  Update:

  • Crash report ID: [6326058f-1fca-4d4d-a080-af8902120119]

  • Crash report ID: [69534b6f-7662-4c09-bf2e-39fff2120104] signature as above

  There are very few reports recent crash with this signature, they could even be your plant. If you follow the suggestions in the article I linked above there is not much that can be done easily. You should try discount the possibility that the cause is malware by scanning with several updated tools.

  Clean reinstall it
  If you find no malware, it can be interesting to try a new re - install and a clean profile, none of them are simple and must be done with care, so first try malware scans, those who will take a while to sort.

• Everytime I open Firefox I get a message: "an attempt to change your home page has been blocked" and firefox crashes

  Could you try starting Firefox in Safe Mode? It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

  Does not work if Firefox: Hold down the option key when starting Firefox.

  If Firefox is running: You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules

  and OK reboot.

  Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

  Any improvement?

  While you are in Mode without failure, you could copy a list of your extensions and paste them into an answer? The best place for this is the support information page - either:

  • button "3-bar" menu > "?" button > troubleshooting information
  • (menu bar) Help > troubleshooting information
  • type or paste everything: in the address bar and press Enter

  Scroll down to the Extensions section, and then select from there until the end of the following table with the mouse and copy. Then paste into a response. It may seem a bit messy but don't worry, we're used to it.

  In addition, if you check your homepage settings, he changed? This article explains where to find that page preferences: start-up, homepage, tabs and download settings.

• Firefox crashes when you open a blank tab

  Only in the last day, I started having problems with Firefox crashing. In the first hour, the problem only seemed to happen when I went to some websites, such as Gmail or YouTube.

  Now, however, Firefox will crash as soon as I open a new empty tab. I am able to start Firefox, and it will show the page to "re-establish the Session. I can use the menu to open, for example, on: supports, but as soon as I do CMD + T to open a new tab, Firefox will crash.

  This seems to happen even when I start Firefox in safe mode.

  I also tried refreshing Firefox and do a new installation of Firefox, but none of these troubleshooting steps solved the problem.

  Hmm, so I recently had my hard drive is not on me, and I had to reformat and any transfer during a backup of my laptop. Since then, Firefox seems to work very well yet. Thanks for all the help and suggestions!

• Firefox crashes or freezes when opened. Help, please!

  My firefox does not open. I have been using Firefox without problems for years until yesterday. I have a Mac OS X 10.10.3. Whenever I open Firefox, it immediately crashes or freezes. I have to go to my dock to "force quit" Firefox. I tried to uninstall and reinstall the latest version of Firefox 38.0.1 several times and no luck. I tried to start Firefox in "safe mode" and as soon as my default screen opens (Yahoo.com) and when I click on anything, whether it's freezing immediately again.

  I'm not able to get Firefox open enough before it freezes to be able to go to 'preferences' to try to change or remove cookies or anything else.

  Also, I had hundreds of bookmarks, when I get Firefox and running, is there a way to recover these bookmarks?

  Currently, I am forced to use Safari which is horrible. Help, please!

  Thank you

  Is there another way to fix the FF on my main account on my computer instead of having to switch everything to another account?

  You do not create another account on the computer. You're doing a
  new user of Firefox with your own user account profile. Firefox may have
  many profiles under the same user account.

• Firefox crashes when I opened my fifth (or several) tab

  I usually kept on 3-4 tabs open and when I click to open a new tab with a specific page, a link to a Google search, either Pandora or a link to another site, Firefox crashes (although Google seems to open correctly every time). I have the 37.0.2 version.

  Report of recent incidents: https://crash-stats.mozilla.com/report/index/9e1774db-98f1-432b-b06e-ad68c2150421

  Thank you user293. I tried various suggestions there, and none seemed to work well that delete my cache and cookies helped temporarily. Then I realized that I had not turned off my computer in days, I turned off for the night and everything seems to work fine now (I feel like a jerk, believe me). Thanks again.

• Firefox crashes after I open a new tab

  Hello
  My Firefox crashes whenever I open a new tab (empty). The same phenomenon occurs in safe mode. Here are links to some of the latest crash reports:

  https://crash-stats.Mozilla.com/report/index/f0fce577-b53e-44BF-a8fa-f7a802150406

  What could be wrong?
  Thank you.

  You might try using a new profile. It might be hard to go at least a whole day without your pets addons, bookmarks, and history... the bookmarks are fairly easy to copy.

  Create a new Firefox profile

  This is in addition and does not replace your existing settings.

  A new profile will be your plugins installed by system (for example, Flash) and extensions (e.g., security suite toolbars), but no themes, other extensions or other customizations. It should also come with fresh data bases of completely fresh settings and a cache folder.

  Out of Firefox and start in the profile using Start Manager > Search box (or run) - type or paste the following and press ENTER:

  firefox.exe -P
  

  Do not delete anything here.

  Any time want to switch profiles, exit Firefox and return to this dialog box.

  Click on the button to create a profile, assign a name like April8 and ignore the possibility of changing the location of the folder. Then launch Firefox in the new profile that you have created.

  It might take some time to determine if the new profile works better than the old. If you want to import your Favorites from your regular profile in the meantime, here's how:

  You can use the dialog library (Ctrl + Shift + b or "Show all bookmarks") to access the restore feature. The trick is to know where to find your bookmark backups in your regular profile. After clicking on file... you can paste this into the space of file name and press ENTER to drill down to your profile folders:

  %APPDATA%\Mozilla\Firefox\Profiles
  

  The semi-randomly-named folder that has your last backup is generally the one that ends with "failure". Click in that one, and then in the folder bookmarkbackups . Here you can choose the most recently updated to restore file.

  Important: restoring a backup bookmark clears all bookmarks currently in your current Firefox profile and replaces it with the contents of the backup file.

  In my view, it is also reasonable to install AdBlock Plus, Restorer of classic theme, and Status4Evar, like those who, by themselves, are not likely to be at the origin of this apparently rare problem. But I wouldn't add all your extensions to the time in the new profile, and if many show extensions system installed, you can disable those you don't actually use.

  - reinstall firefox
  - refresh firefox
  - start firefox in safe mode (still crashes)
  

  I also tested in safe mode Windows and do not have the problem. According to me, indicating that there is another piece of software that is the cause of the crash, but I do not know how to identify what other software it is.

  Firefox does not record these subject aircraft crash: crashes so I have no newspaper to share.

  OK, so this I've not exactly "resolved" the issue, but I have a solution. I dropped Firefox and installed Firefox developer edition instead:

  I don't have the same problem when using that. Fact.

• Firefox crashes without opening because I have installed the latest Norton antivirus in windows XP

  I have three computers running XP and the latest version of Norton anti = viral... Two are working well. On the third, firefox crashes whenever I try to use it because I downloaded the last street of Norton Security. Norton will not open either. If I open in safe mode with networking, I can access the internet with firefox.

  Start Firefox in Safe Mode {web link}
  While you are in safe mode disables the Norton modules.
  Then restart.

• How can I fix Firefox crashing whenever I have many tabs open?

  I'll try to keep this short. I'm used to be a Firefox user for a long time... as he was released from first. I've always had problems with it crashing when given the many tabs open. I could not take more and jumped ship. After a brief period using Chrome, I decided to install the 31 version and try again.

  I still have the same exact questions. The problem has persisted through generations of computer with the increase in power and memory.

  Currently I am running an i7 4770 k with 32 GB of RAM and a GTX 770, SSD, etc.. I just installed Firefox yesterday after fed up with Chrome and some of its questions. Firefox crashed at about 6 - 10 times since then.

  I'm a heavy browser. I have normally accumulate tons of tabs open, more than 100 + tabs open at the same time (maybe more, I've never counted). I understand that this may use a lot of memory, but I have a ton of memory. My use of the system does not exceed 30% never, but Firefox crashes regularly. I'm actually a little surprised that it seems worse now that she has never in the past. It crashes, I restore and it will crash again in 5 minutes. I don't have any add-ons installed. I had Ad Block Plus briefly installed, but I uninstalled that, once these accidents have begun.

  What is Firefox, no Add-ons, no extra charges, nothing else to change its performance. It crashes constantly. It is perhaps just the last attempt before I'll look elsewhere.

  Hello, Yes, it looks like an accident of lack of memory (probably due to many tabs open). you could try a port 64-bit firefox who will be able to use all of the available memory: https://www.waterfoxproject.org/

• If I try to open troubleshooting information, firefox crashes.

  Firefox crashes when I try to open "of troubleshooting information" under the Help menu. It also blocks on several websites.

  Firefox crashes, or a page block upward, so I close the browser (sometimes have to close it by the Task Manager. When I try to re - open firefox, need me to pages that just crashed, rather than my home page.

  Yes, it's normal. You want to disable that? There are a couple of settings related to resume your previous session after a crash:

  (A) resume automatically, but if Firefox crashes twice in a row, displays a list of windows and tabs and let me choose. (default)
  
  (B) does not resume automatically, always show the list of windows and tabs and let me choose; (I recommend this approach) or
  
  (C) never automatically resume and do not display the list.

  Switching to B or C requires a visit to Firefox about: config preferences editor.

  (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

  (2) in the search above the list box, type or paste sess and make a pause so that the list is filtered

  For "B":

  Double-click the browser.sessionstore.max_resumed_crashes preference from 1 to 0 (that's a zero).

  For "C":

  Double-click on browser.sessionstore.resume_from_crash preference to change its value from true to false.

  Hello disappear, what kind of sound card do you use? Mozilla developers are working on a fix for some models that hang on some content audio html5, which should already be present in firefox nightly - for more details you can also check the #970147 bug.

  In addition to what has been said here, you can try to disable sounds "improvements" in the properties of the windows device speaker as a temporary workaround...
