As above, without fail, when Firefox updates I loose all the additions I have made to the spellchecker dictionary. This has been happening for several years now!

I understand it is crashing, please can you provide the crash reports for further analyzing.

As for the dictionary, the file that the words are stored in are mentions here: *

Make a copy of that file every once in a while to have a backup work around until we can figure out what is happening.

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.

  1. Enter about:crashes in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.

Did you reset/refresh Firefox and have created a new profile?

When you reset/refresh Firefox then a new profile is created and some personal data (bookmarks, history, cookies, passwords, form data) is automatically imported. The current profile folder will be moved to an "Old Firefox Data" folder on the desktop. Installed extensions and other customizations (toolbars, prefs) that you have made are lost and need to be redone.

If you have the "Old Firefox Data" folder on the desktop then you can look for the persdict.dat file and copy this file to the current profile folder.

You can use this button to go to the current Firefox profile folder:
