Dropbox Error (403)

Error (403) in Dropbox When you Login: How to Fix the Problem

In Web & Safety by Fathi Arfaoui17 CommentsLast Updated: March 18th, 2018

Dropbox is one of the top cloud storage service providers trusted my millions of people and companies. However, it seems that their website has issues with most browsers and especially with Google Chrome and Firefox. The famous Error (403) stops users to login to their accounts and manage their files.

The big problem is that when you check your login details, you will find them correct. However, you can’t login again to your account, and the site keeps getting the forbidden error, every time you want to access.

These issues happen in Windows 7, or 8, Windows phone, and mobile phones in general. But, the problem can also happen with iOS and other operating systems.

Error (403) in Dropbox

The problem is your web browser cookie settings or the Dropbox cookies themselves. To solve and fix the problem, you just need to delete the Dropbox cookies from your browser, and you will access your account again, this will work in the majority of cases.

How to delete Dropbox cookies from your browser?

For Google Chrome, click the options menu at the top right corner of your browser, and choose “Settings”, as the below screenshot.

Now, you will get the settings page, and you need to scroll down and click on “Advanced Settings.”

Then, click on “Content Settings” in the privacy section, as the below screenshot.

You will get a pop-up window with options and a list of settings, just click on “All cookies and site data.”

Now, search for “Dropbox” in the search box, at the top of the pop-up and delete all the entries that include the word “Dropbox”. Next, save the two windows to apply the changes.

Finally, visit Dropbox again, and you will be able to log this time. It’s a cookie issue and you need to clear your browser data the next time, or simply, use this method to remove the cookies manually, you will need the same thing every time you get an error.

You can read how to remove the website cookies in Firefox. On the other side, for Windows Phone, read this page to delete cookies and browsing cache.

If you’re using Safari, then, the safest and easiest way is to clear all the website data, including cookies. For that, click “Safari” at the top left area of your browser, just next the Apple logo. Then, click on the fourth option called “Clear history and website data”. Finally, close and open the browser again and try to login to your Dropbox account.

As you can see, it’s just a cookie problem that makes people out of their accounts during hours, or even, days, if they never want to clean their browser data. This will not fix all the future problems, but you need to repeat the same step every time you have issues logging to Dropbox.

They should work on this problem and fix it as soon as possible. People who save important data and backups in their accounts, and they need to have access all the time without errors.

If you’ve solved your problem in another browser, especially, on smartphones, please share your ideas and your comment and help the others who have the same issues. Dropbox is great, but sometimes, things can look out of control for users who cares about their sensitive data.

      Hi Adam, this tutorial is valid for your Firefox version, it’s the latest 35.0.1, please follow the above screenshots one by one, and remember that you need to click ”remove individual cookies” when you get the window. It will work.

  2. Hello,

    I checked my advance settings and cookies and I did not see any cookies listing for Dropbox. This may be a different issue, I get a message from Google “This webpage is not available” and in Firefox Dropbox page does not open. However, I am working in small a “Net” book computer and it comes with Windows Starter version 7 program, because I never experienced this issue with Dropbox before.

      Hi Linda, it’s not a problem with the operating system. It’s just with the cache, so, if you can’t see the Dropbox cookies, then, delete all your browser and intent cache cookies. That will solve the problem in general. If it’s not the case, try with another device, and use a laptop to verify the case.

  3. Many Thanks! I will try that. I read your bio, very impressive! I am in the process of learning WordPress and designing a website and blog for our webTV series, Full Moon. I am sure that I will have questions and will check in here as well. Thank you again!

  4. I have a Samsung WB35F camera a small Wi-Fi Point ‘n Shoot.
    It comes with – I guess you’d call them built-in Apps – to connect to and upload photos to Facebook, Picasa, YouTube and Dropbox.

    I’m trying to connect to Dropbox to upload photos. It will connect to my Wi-Fi. When it does, it then loads the page to sign into Dropbox. I give it my credentials – my email and password, and it then displays either:

    403 error, Reload page or restart browser
    HTTP Error 403 Forbidden RETRY; CANCEL

    I’ve called Samsung and they tried walking me through this and it still did not work. They had me update the firmware and reset the camera, and nothing I tried helped. They told me it’s probably defective and said I can send it for ‘repair’ to fix this problem.

    They send me a UPS label and I sent the camera to them, but they were not able to make it work. They told me, in writing, that I “can send files easily from your camera to a smart phone. The camera connects wirelessly to smart phones that support the MobileLink feature”, and that photos can then be “placed into Dropbox from there.”

    Can’t do that. I don’t have a smart phone. On top of which, the camera has Wi-Fi, and an App for Dropbox. It’s advertising says it can upload to Dropbox.

      This is a little complicated situation as you don’t have a browser, but just a login option in your camera, hope someone can help.

    2. I nave the same problem on my “wb1100f” camera. Tomorrow i will ask to Samsung support

    3. I stand, I kept in touch with Samsung with your same problem on WB1100f camera. They told me to try connecting the camera via hotspot to my smartphone. I tried but nothing new. They told me to bring the camera for assistance. ( I really think they have to update the firmware but they can’t tell me nothing)
