You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks and history and cookies and passwords and cache and exceptions, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

I cannot download files from any link on any site, not just one. Deleting the cookies won't do anything for me.

Thank you . The only differences are that the other FF profiles do not have add-ons. Here you go: Application Basics

It could be the work of one of your add-ons. Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

Thank you, Fred, but I tried that already. I disabled the add-ons one by one (restarting each time) and the problem persisted throughout that process. I deleted the add-ons one by one (restarting each time) and the problem persisted. In the meanwhile, I created a new profile and installed all the add-ons I have in my primary FF profile. I am able to download files from a link in this test profile.

I then copied the contents of the primary profile folder into this test profile (after backing it up) and was no longer able to download files. I suspected my preferences, since those are also suspended when FF is started in 'safe mode', but don't see anything that would affect downloading.

Remove the preference file you copied, then redo them manually.

Let us know what happens.

Did you try to use "Forget About This Site" like I suggested above since you wrote that only this website is affected?

You can try to rename permissions.sqlite to see if that has effect.

When you use extensions ("3-bar" menu button# or Tools -> Add-ons -> Extensions) that can block content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure such extensions do not block content. There is security software that can interfere with loading content, so check that as well.

Cor-el, I am unable to download from any web site, even ones I have never visited (where I have no cookies). I did perform 'forget abut this site' on the ones I normally download from, and that didn't wiork either.

Fred, Do you mean prefs.js? I don't have a user.js file

Fred, I deleted prefs.js and restarted. Before even modifying any setting, /i tried to download a file and could not.

I renamed permissions.sqlite then started the profile. I still cannot download files.

If the new profile worked without making modifications then try another new profile, but this time only copy one file at the time and check if it works and do not install extensions for now.

You can copy files like these to the current Firefox profile folder to recover specific data. Be cautious with copying SQLite databases if you had specific problems.

• bookmarks and history: places.sqlite
• bookmark backups: JSON backups in the bookmarkbackups folder
• cookies.sqlite (cookies)
• formhistory.sqlite (saved form data)
• logins.json and key3.db (decryption key) for Passwords saved in the Password Manager
• cert8.db and possibly cert_override.txt for (intermediate) certificates stored in the Certificate Manager
• persdict.dat for words you added to the spelling checker dictionary
• sessionstore.js for open tabs and pinned tabs and tab groups

Be cautious with cookies.sqlite and prefs.js and files that store site specific data like these two.

• permissions.sqlite for Permissions and possibly content-prefs.sqlite for other Site Preferences

Alright. I created a new profile and copied the files from the primary folder into it, testing the download capability successfully after each copy. I then moved the folders that weren't related to add-ons one by one, and tested the download capability successfully after each copy. I then began installing my add-ons, and tested the download capability successfully after each copy. The only things left are the plug-ins (OpenH264, and widevine; Shockwave installed itself at profile creation). They "will be installed shortly" according to the add-ons manager.

So far, so good.

Alright, the new profile is up and running with all my extensions and preferred settings. I also refreshed the 'bad' profile with a copy from my backup drive. That also now downloads anything I try.

It would have been nice to know what became corrupted/incompatible, but I'm going to move on.

Thanks for your input.

Glad to help. Safe Surfing.

These add-ons can be a great help by backing up and restoring Firefox

https://addons.mozilla.org/en-US/firefox/addon/febe/ FEBE (Firefox Environment Backup Extension)

FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backups of files that you choose.
