Diễn đàn hỗ trợ Firefox

Please note that I have Autism, please be gentle and if telling me how to do it, give simple instructions like below, thank you.

Aim: The goal is to disable Private Browsing mode in Firefox, ensuring that it cannot be used on the system.

I have spent hours on this. With no luck.

1. 1. 1. Steps Attempted:

1. **Adjusting Settings**:

  - Open Firefox.
  - Click on the hamburger menu (three horizontal lines) in the top-right corner.
  - Select "Options" or "Settings".
  - Go to "Privacy & Security".
  - Uncheck the box next to "Always use private browsing mode".
  - Restart Firefox.

2. **Modifying History Settings**:

  - Open Firefox.
  - Click on the hamburger menu (three horizontal lines) in the top-right corner.
  - Select "Options" or "Settings".
  - Go to "Privacy & Security".
  - Scroll down to the "History" section.
  - Change the setting to "Use custom settings for history".
  - Uncheck the box next to "Always use private browsing mode".
  - Restart Firefox.

3. **Using about:config**:

  - Open Firefox.
  - Type `about:config` in the address bar and press `Enter`.
  - Accept the Risk and Continue.
  - Search for `browser.privatebrowsing.autostart`.
  - Double-click on it to change the value to `false`.
  - Restart Firefox.

4. **Creating a New Firefox Profile**:

  - Open Firefox.
  - Type `about:profiles` in the address bar and press `Enter`.
  - Click on "Create a New Profile" and follow the prompts.
  - Launch the new profile in a new browser.
  - Go to "Privacy & Security" settings and ensure "Always use private browsing mode" is unchecked.
  - Restart Firefox.

5. **Refreshing Firefox**:

  - Open Firefox.
  - Click on the hamburger menu (three horizontal lines) in the top-right corner.
  - Select "Help" and then "More Troubleshooting Information".
  - Click on "Refresh Firefox" and confirm.
  - Firefox will reset to default settings and restart.

6. **Checking Firefox Policies**:

  - Open Firefox.
  - Type `about:policies` in the address bar and press `Enter`.
  - Review any active policies that might be enforcing Private Browsing mode.

7. **Uninstalling and Reinstalling Firefox**:

  - Uninstall Firefox from your system.
  - Download the latest version from Mozilla's official Firefox download page.
  - Reinstall Firefox and check if the issue is resolved.

8. **Registry Edit (Windows)**:

  - Press **`Win + R`** to open the Run dialog.
  - Type **`regedit`** and press **`Enter`** to open the Registry Editor.
  - Navigate to the following key:
    ```
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox
    ```
    - If the `Mozilla` or `Firefox` keys do not exist, you'll need to create them:
      - Right-click on the **`Policies`** key.
      - Select **`New > Key`**.
      - Name the new key **`Mozilla`**.
      - Right-click on the **`Mozilla`** key.
      - Select **`New > Key`**.
      - Name the new key **`Firefox`**.
  - Right-click on the **`Firefox`** key.
  - Select **`New > DWORD (32-bit) Value`**.
  - Name the new value **`DisablePrivateBrowsing`**.
  - Double-click on the **`DisablePrivateBrowsing`** value.
  - Set the "Value data" to **`1`**.
  - Click **`OK`** to save the changes.
  - Restart your computer to apply the changes.

These steps represent a comprehensive attempt to disable Private Browsing mode in Firefox.

If I use chrome it is OK I have used Firefox for ages without problems Gil

I am logged out of my sbcglobal.net account automatically when I try to login. This happens only in Mozilla Firefox, other browsers are fine. So the problem is with Mozilla Firefox. I got rid of cookies with no result. Any suggestion?

I recently performed a system reset and upon re downloading Firefox I can't seem to find any of my 50+ tabs that I had open previously, all of them I need for one reason or another, history is empty, can anyone please help explain how to get them back in simple steps?

Unfortunately, my workflow involves dealing with multiple PDF files per day. However, for some reason, Firefox's behavior with regards to PDF files is inconsistent.

• If I set the Action to Save File, Firefox downloads all PDF files, including those that it can normally open in the browser when I click a link (e.g. files hosted in servers that allow direct access to PDF files). As such, my Downloads folder is cluttered and needs to be cleaned regularly to delete the PDF files that were downloaded even if I could have opened them in the browser.
• If I set the Action to Open in Firefox, Firefox can now open those hosted PDF files in the browser instead of downloading them to disk. However, every time I download a file, Firefox then opens the file in Firefox after downloading, even though I need to edit the PDF file somewhere else.

Would it be possible to set Firefox's behavior so that it does BOTH of these things:

1. Open PDF files that can be opened in the browser without downloading in Firefox without needing to be downloaded, AND
2. Do not open downloaded PDF files in Firefox after downloading is complete.

I cannot find my auto-fill data for first name, last name, phone. I see Addresses and Credit card only. My phone number changed and I would like to edit that auto-fill data

open tabs crash every few minutes. Very frustrating. This behavior just recently started. I restarted Firefox: no change. I put it in troubleshoot mode: no change. Any suggestions?

Not an urgent problem but ...

The following site displays with a grey box in the lower left corner but works fine with Chrome.

I got a email from you telling me I had purchased something from you. I would like to get into my account so I can understand better exactly what I got, and what my future bill will be. Thank you

why does firefox perform badly with paramount streaming? it doesn't happen netflix or amazon or apple etc This does not happen with other browsers such as chrome

Firefox needs to be restarted each day, and still has stalling, repeating and stopping during any paramount stream

Will this ever be fixed?

Seriously considering abandoning firefox after so many years

Latest version seems to have added action imeaditly I hover over somthing with the mouse pointer this is trulley maddning how do I stop this behaveur or increase the delay?

I've seen other people ask this question, and the stock answer appears to be: a) They may be different subdomains, but they're the same site. b) Just add an extra bit on the end of each user name so you can get at the correct one.

Unfortunately...

a) No they are most definitely not the same site: myFirstClientsDevSite.mytestdomain.com mySecondClientsDevSite.mytestdomain.com myThirdClientsDevSite.mytestdomain.com myFirstClientsUATSite.mytestdomain.com mySecondClientsUATSite.mytestdomain.com myThirdClientsUATSite.mytestdomain.com

You see the problem? Firefox treats all those sites as being "the same site", even though they patently are not.

b) I'm working with a lot more than three clients. Plus, that suggestion is basically "we admit that our product is broken, here's a work-around that a few people may be able to use".

And finally: I'm pretty sure that Firefox used to be able to discriminate between subdomains, so the question isn't so much "how can I get it to work", as "why was it taken away in the first place".

I am NOT a fan of this relatively new Full-screen mode at all unless I initiate it when watching a movie or in very few other instances. I don't like any device second-guessing or anticipating what I need to do and when or if it needs to do this for me. It has caused me more problems than it has helped, and injected some frustrating delays getting what I want done due to the added need and interruption of being paused to constantly press F11 again and again. It's not second nature and at this point, I don't think it will be. I don't need or want this feature and I don't understand this new world where features have to be nailed down and locked now with the "like it or lump it" mentality without option to remove or disabled this? (Sorry, I don't like MS Edge either, and not only for this reason!) I would be happy to go back to a previous version of Firefox that is without this feature, if this is the only answer. I'm hoping it is not?

There was a previous very brief post on here that directed users to go to about:config and set full-screen-api.enabled to false in order to disable this feature, but no one positively confirmed that it worked and the thread was closed. This doesn't appear to be working for me with the most current version of Firefox.

Is there someone who can help give me peace in my life again by showing me how to disable this permanently and forever? I know about F11 and don't ever want to have to press it again! I would appreciate any help, and you might even make my Christmas list if it works?

Thanks!

Hello

(Firefox, Win10, desktop, latest built)

Unfortunately, I'm not an expert, so, when I found something relevant, online, it was way out of my league.

I've just realised there's something wrong with the bookmarks.

Sometimes I cannot save bookmarks. Sometimes I can.

When I move bookmarks, they seem to disappear.

I delete a few bookmarks, but those bookmarks remain there as if nothing has happened.

I tried to rename a couple of bookmarks, but nothing happens, and I cannot remove such bookmarks.

I've scanned my computer for malware, viruses, etc, but everything seems ok.

I'm not sure what is happening

Cheers

Christian

At the latest update firefox 64bit crashed and I neede a totally new install of firefox. After downloading it said, partly installed we will repair the upgrade and it did. However only a few bookmarks were recovered many of which were over a year old... So how to recover my recent bookmarks, which were in sorted in named bookmarkfolder, e.g. home/study/work

I would assume a backup frommy firefox account but that does not show a solution..?!??
