Firefox Developer Edition opens two separate processes
Very good, I am using Firefox Developer through PortableApps, and I have experienced a very unique problem, which I still do not find a definition: when I want to run it opens normal, but when I open it through a link in another application opens another window, so now I have two different Firefox processes. And I know this because, the first time, I opened it normally and placed my Firefox Accounts access, and when I open the new link, it opens as if it were clean, and I had to re-position my access again. And this is really uncomfortable. The height is now that I want to install an addon, and I get this error: "An unexpected error occurred during installation." How can they do so that this unique "feature" is no longer given?

It is likely that you have two Firefox profiles,m a .default profile that you probably use when you start Firefox normally and a second .default-release profile that is used when you start Firefox via an external link.
You can open the about:profiles page via the location bar to check whether multiple profiles are present and what profile Firefox currently is using.
- Do NOT click any Remove button on this page.
- https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
If you have two profiles then best to avoid this issue is to start using the default-release profile and transfer all necessary data to this profile.
You can copy files like these with Firefox closed to the current profile folder to recover specific data.
- bookmarks and history: places.sqlite
- bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder
- cookies.sqlite for the Cookies
- formhistory.sqlite for saved autocomplete Form Data
- logins.json (passwords) and key4.db (58+) or key3.db (57 and older) (decryption key) for Passwords saved in the Password Manager
if you only have key3.db then make sure to remove an existing key4.db - cert9.db (58+) or cert8.db (57 and older) for (intermediate) certificates stored in the Certificate Manager
if you only have cert8.db then make sure to remove an existing cert9.db - persdict.dat for words you added to the spelling checker dictionary
- permissions.sqlite for Permissions and possibly content-prefs.sqlite for other website specific data (Site Preferences)
- sessionstore.jsonlz4 for open tabs and pinned tabs (see also the sessionstore-backups folder)
You will have to reinstall extensions and redo other customizations.
Firefox 67 and later can use a dedicated profile for each of the Firefox update channels and will lock the profile, so it can only be used by Firefox in a specific installation folder.
Thank you very much, I already managed to visualize that link, and I saw that I have three enabled profiles. Now the doubt is to know which of all those is the one that loads in a certain moment. For now, the one that loads when it calls a link doesn't have the Screenshot Tool Editor plug-in enabled, which the first profile does. I don't think I would worry about "purging" everything, but if you tell me that I have to reinstall extensions, and the screenshot is no longer on the addons website, I worry a lot.
The "Help -> Troubleshooting Information" (about:support) page and the about:profiles page should tell you which profile Firefox is currently using.
