Hi AMXQZ39, Firefox should work satisfactorily for most users with its default settings. We do not discuss hacking and heavy customisation of preferences on this forum. Some changes could cause instability or be unsuitable in some circumstances. You could consider reversing some or all of those changes if you think that was part of the problem. * See [[Refresh Firefox - reset add-ons and settings]] <br /> That will reset preferences, but also remove Firefox extensions * [[Reset Firefox preferences to troubleshoot and fix problems]] Try Firefox in its SafeMode and if tat does not help consider the steps above. If you have continuing crashes explain what you have tried to fix that and then let us have two or three Crash IDs . Navigate to ''about:crashes'' (They start '''bp-''' Forum software converts then to links but not until AFTER you post them ) See * [[Firefox crashes - asking for support]] * [[Firefox crashes - Troubleshoot, prevent and get help fixing crashes]] ----------- We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash. #Enter ''about:crashes'' in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below. #Copy the '''5''' most recent Report IDs that start with '''bp-''' and then go back to your forum question and paste those IDs into the "Post a Reply" box. ''' Note:''' If a recent Report ID does not start with '''bp-''' click on it to submit the report. (Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.) ;[[Image:aboutcrashesFx29|width=500]]
