cant login to a specific site from a specific computer only on FF

more options

Hi all, A new problem which started recently and I haven't seemed to figure it out. When trying to login (username+password) to a specific site I'm working with, I get an error message saying that "The form's details are wrong. The page willreload". The page then reloads and goes back to loging screen only the rubrics are empty. Password and username are correct, loging in via Chrome (on the same computer) works just fine. In addition, Loging in on a different computer via Firefox works as well! So only this computer, and only on FF.... I have earased cookies \ cach \ temp files. I've also went and uninstalled FF and re-installed it. Deleted the profile (manually) and started a new one....tried verious boxes checked and uncheck in the privacy menu...No new add ons, or extensions. Nothing seems to work. This is so frustrating... I'm on Dell inspiron, Win 10, FF version 59.0.2 64 bit.

This issue can be caused by corrupted cookies or cookies that are blocked.

If clearing cookies didn't help then It is possible that the cookies.sqlite file in the Firefox profile folder that stores the cookies got corrupted.

  • rename/remove cookies.sqlite (cookies.sqlite.old) and if present delete cookies.sqlite-shm and cookies.sqlite-wal in the Firefox profile folder with Firefox closed in case cookies.sqlite got corrupted.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Clear the Cache and remove the Cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"clear the Cache:

  • Options/Preferences -> Privacy & Security -> Cached Web Content: "Clear Now"

"Remove the Cookies" from websites that cause problems.

  • Options/Preferences -> Privacy & Security -> "Use custom settings for history" -> Cookies: "Show Cookies"

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block (wanted) content.

You see the shield icon at the left end of the location/address bar in case content is blocked by Tracking Protection.

  • click the shield icon for more detail and possibly disable the protection
  • check the Web Console for more detail about what content is blocked by Tracking Protection
  • "3-bar" menu button or Tools -> Web Developer

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 history and cookies and passwords and exceptions and the full cache, 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.

Unfortunately I've tried all of the above with no success prior to posting this question here... Any other suggestions?

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?


One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}

You can try a New Private Window to see if that works. If you see a shield icon in the location/address bar then disable Tracking Protection.

Also make sure you do not block cookies. You can try to enable third-party cookies temporarily.

Could you confirm that the error is for an incorrect login? If you try using an obviously incorrect password in different browsers, do you get that identical message? Just wondering whether it could be a different problem. Sometimes sites protect their login interface by requiring hidden form fields (anti-XSRF).

Private browsing doesn't change anything. Still the same.

The error is not for an incorrect password or username. It is a notification I haven't seen before (never). It simply says : (translating from my language....) "Form details wrong, Page will re-load". This notification does not repeat anywhere else, with or without the right password. This is a site I use on a daily basis, so the interface hasn't changed. I am still confused as to why, even after uninstalling FF and re-installing it the problem remains. If it were corrupted cookies files or anything from withing the installation folder, shouldn't it be erased by now? This bugs me on so many levels....:) Now I HAVE to find a solution :)

No, since users have a history of changing versions, Firefox doesn't remove your profile folder containing your data when you uninstall, and it re-uses it when you reinstall.

Do you want to try:

New Profile Test

This takes about 3 minutes, plus the time to test your site.

Inside Firefox, type or paste about:profiles in the address bar and press Enter/Return to load it.

Click the Create a New Profile button, then click Next. Assign a name like April2018, ignore the option to relocate the profile folder, and click the Finish button.

After creating the profile, scroll down to it and click the Set as default profile button below that profile, then scroll back up and click the Restart normally button. (There are some other buttons, but please ignore them.)

Firefox should exit and then start up using the new profile, which will just look brand new.

Does the site work any better in the new profile?

When you are done with the experiment, open the about:profiles page again, click the Set as default profile button for your normal profile, then click the Restart normally button to get back to it.

Hi jscher, Well the thing with the profile didn't work. Forgot to mention that as part of my attempts to solve this issue, I've uninstalled FF and even deleted the entire folder which the profiles were located (which caused a different problem once I re-installed FF...But I could resolve that one...). So even with a brand new FF it stayed the same. Do you know what registry keys are altered when installing FF? maybe I could delete them as well.

more options

I don't think there are relevant registry keys, but you can search around in the SOFTWARE areas if you like and take your chances.

Is there any different in connection paths between Firefox and Chrome? You can check Firefox here:

  • Windows: "3-bar" menu button (or Tools menu) > Options
  • Mac: "3-bar" menu button (or Firefox menu) > Preferences
  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the search box at the top of the page, type proxy and Firefox should filter to the "Settings" button, which you can click.

The default of "Use system proxy settings" piggybacks on your Windows/IE "LAN" setting. "Auto-detect" can lead to a flaky connection. You may want to try "No proxy".

Any difference?
