Firefox 94.0.1 (64 bits) freezes when trying to download
Hello,
I noticed recently that Firefox 91.0.1 (64 bits) freezes on my PC Windows 10 when I try to download a file, or even to modify download settings in the parameters page.
So, I have deleted all hystory, cookies, and cache and I started in "fail safe mode" (extensions disabled), but same problem.... So I created a fresh new profile, and it worked Ok ! No freeze, no problem.
I have probably a conflicting setting in my main profile, but which one ? How to find it ?
Thank you by advance if you you have any idea to help me.
Marco

As the new profile does not have the problem, you are better off using it rather than trying to fix the old one.
When you are ready, we can start moving parts of your
old data and Copy it to the new profile.
First; open your file browser to the New profile;
Type about:support<enter> in the address bar.
Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.
Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder
Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.
Second, open another file browser to the Old profile. You should see it on the directory "tree" in the first file browser. Right-click on that folder and select Open In New Window.
Warning ! ! Only Copy the files you are told. We will avoid anything that might cause problems. Here is the list of files;
cookies: cookies.sqlite Do not bother. Cookies will be created when you return to the website. However, you will have to log in everywhere. And you may lose any settings that websites store on your computer.
extensions(add-ons, themes): it would be better to download them fresh. If you need to remember what add-ons you had, open the extensions sub-folder and look at the .xpi files
logins.json and key3.db [v58+]key4.db : These are the password files. Copy Both !
persdict.dat : custom dictionary - words you added to the dictionary
mimeTypes.rdf [v55+]handlers.json : What to do with what type of file.
places.sqlite : History and Bookmarks.
prefs.js : Your settings. Note: If you were having problems, this could be contaminated.
cert8.db [v58+]cert9.db and possibly cert_override.txt : Stores all your security certificate settings and any SSL certificates you have imported into Firefox. If removed, the cert8.db, cert9.db file will be replaced.
search.json.mozlz4 : file stores the user-installed search engines that are available in the Firefox v47+
search.sqlite file and searchplugins folder store the search engines that are available in the Firefox Search bar before Firefox v47
Copy these files from the old to the new. You may get a message that the files already exist. Choose to over-write for each file.

Ok, thanks for tour answer !
But I'm not 100 % satisfied : This is clearly a big bug ! And Ok, there is a workaround : create a new profile, and lose all your settings and extensions...
Not a very good answer from Firefox devs...
Do you consider your answer at a general user ? (not an ingeneer ?)

Sorry, but my system is in French...
I will try your solution, even if I find it not to do for a basic user ...
Just another workaoround to not fix a very big bug...
Just a shame.
(I can also use Chrome or other browser to download a file, if Firefox latest version cannot do that....)
You can check for problems with preferences. You can delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.
You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
- Help -> More Troubleshooting Information -> Profile Folder/Directory:
Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder - https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data
Yes, "you can !" ...
Thank you for your help. Not an easy "workaround" for a basic user, either...
Perhaps better to fix the problem in the next version of Firefox...
Anyway, thank you.
