Find that at each update, the Startpage search engine is re-installed WITHOUT my permission. I understand startpage can be defined as a PUP, and I don't trust it. The most aggravating thing is that installing add-ons and extentions without users' permission is unconscionable.

Would like to know if there is any way I can block the reinstallation of this at each update.

Thanks.

Hi, I just installed Windows 11, version 24H2 and now in Firefox I'm continually prompted with "Awaiting Location Permission, Grant Firefox location permission in system settings".

The problem that location has been turned off by admin on this computer. How can I stop these continual prompts from Firefox? I have checked the box in Settings to block location requests from new websites but am still getting the prompts.

Thank you.

Why is my browser stating that it is managed by my organisation.

I have never used it fr work and it is my personal laptop. Please kindly provide steps to remove this

Good afternoon,

If necessary, I am available to add more information about this case (145005), in English or Portuguese.

I'm encountering some difficulties with my current account, which is locked out. I would like to request assistance from the support team to help me delete my account and remove my personal information from the platform. However, I'm having trouble finding the contact information for the support team. I couldn't locate their email address or phone number, and I'm hesitant to post my personal email address and information on a public forum.

I'm feeling quite frustrated, as I've never encountered such challenges with an app before. It appears that I'm unable to reach the Firefox support team at the moment. Can someone please provide guidance on how I can securely and privately request their assistance in deleting my account and personal information?

I had to create a new account just to post this question because my original account got locked out. This happened because I recently acquired a new phone and didn't transfer the two-step authentication information to my new device.

Up until 6 months ago I was easily able to access all my bank accounts on line using Firefox. I can still access others but not Capital One 360 on line banking. When I try to access Capital One I just get the message that " there has been snag and to try again" which does not work. So I can access my Capital One account only thru Google Chrome. Capital One says that the reason is that Firefox does not update their security setting to the level they require. Can anyone tell me if this is the problem or if there is some other reason why I can no longer use Firefox to access this account.

Hi all,

I have a question regarding the permission requests of the Simple Tab Groups extension by Drive4ik.

As I'm sure many of you know, this extension needs to: This add-on needs to:

• Download files and read and modify the browser’s download history
• Monitor extension usage and manage themes
• Display notifications to you
• Access recently closed tabs
• Hide and show browser tabs
• Access browser tabs
• Store unlimited amount of client-side data
• Access your data for all websites

This add-on may also ask to: Read and modify bookmarks

Theoretically, I find this extension useful but I am concerned about the "Access your data for all websites" requirement. I read through Mozilla's permission request messages for Firefox extensions documentation and it seems like granting this extension these permissions would be a huge risk for the work I do– investigative journalism. It seems like I'll trade organizational benefits for a wider attack surface.

Can anyone speak more about the risks involved with using this extension, the trustworthiness of the developer, and why it needs the "Access your data for all websites" capability?

Thank you.

Recently transferred from Chrome. My understanding was Firefox private browsing was supposed to work similarly to chrome incognito mode; once you close the browser, all local files are deleted and cookies are cleared.

However, with Firefox it maintains my logins. If I log into an account while private browsing and the close the browser, I’ll still be logged in next time I go to the website even if it’s days later (and I have never logged into this account in a non-private browsing window!)

I never had this issue using chrome incognito, so it seems to be a Firefox problem.

Is this just not something Firefox supports? Is there any way to prevent storage of cookies and private data?

Now that Mozilla/Firefox have joined Google on the dark side, who is everyone switching to? I would like something that works well in both Windows and android. I hear Opera can't be trusted and I don't like how there are like 6 difference versions of Opera in the android app store. DuckduckGo is just badly made IMO. Edge causes some glitches with one of the sites I use most. Should I try Brave? I just want a browser to BROWSE the web. I don't want AI. I don't need a VPN or adblock built in. I don't want a "gamer" browser. A decent local password manager would be nice but I don't want to have to make an account to use it. I know if the product is free, you are the product, so I would almost prefer a browser you pay for but oddly that doesn't seem to be a popular option. Probably because the user data the companies collect makes them more money then people would be willing to pay. Sad times. I miss the 90's.

Problem: Persistent 150 KB of Cached Web Content For several years, I have gone to “Settings” / “Privacy & Security” / “Cookies and Site Data,” clicked the Clear Data…” button, checked both “Cookies and Site Data,” and “Cached Web Content,” and clicked “Clear”, and consistently gotten BOTH “Cookies and Site Data,” and “Cached Web Content” down to “0” zero. Recently, I have been unable to “Cached Web Content” to go below “150 KB of disk space.”

         I have NOTHING listed in “Manage Cookies and Site Data” or “Exceptions -- Cookies and Site Data.”
         I have tried reinstalling, but the problem has persisted.
         On the assumption that this is malware problem, I have continued to use Mozzella VPN, but stopped using the program for browsing, etc.  Should I stop using it altogether until the problem is fixed?
         Can you tell me how to get rid of the last “150 KB” of “Cached Web Content”?

I want to create a list of allowed web sites in settings/cookies&data/manage exceptions, but it seems I have to enter each site MANUALLY. I would like to do this more quickly and easily by just selecting sites in the "manage cookies" list and designating them as exceptions. Or is there already some other way to do this that I haven't found? Also, after I have made exceptions for all my important sites, by whatever means, can I assume that I can press "delete all" in the "manage cookies" list and the allowed sites will not have cookies removed? What happens to exceptions if I select "delete cookies and site data when Firefox is closed?" If there is no way to make exceptions other than manually, I respectively request that some convenient method be added to the program. Thanks for any response.

Having spent a frustrating weekend being unable to log into Coventry Building Society's online banking app, I phoned them this morning to be told they consider Firefox insecure and no longer support its use. The app accepts my username & password, tells me they are going to 'phone me with an access code' and then displays "Page not found". Anyone know of any other bank or similar who would believe Firefox to be insecure?

I got an email supposedly from breach-alerts@mozilla.com that claims there are currently 3 data breaches and has this link to resolve: https://blrv1ly5.r.us-west-2.awstrack.me/L0/https:%2F%2Fmonitor.mozilla.org%2Fuser%2Fdashboard%2Faction-needed%3Futm_source=monitor-product%26utm_medium=product-email%26utm_campaign=monthly-report-free-us-scan-no-exp-yes-breach-resolved-no%26utm_content=resolve-exposures-us/1/01010195ceba1024-6e3f74fe-119a-4e2e-9033-398671a830d9-000000/DDeGOTLjROOXCCk2fJvXJbdefc4=419

This seems like a phishing email, is it legit? Should I find another browser?

I have all options enabled to save addresses and credit cards.

When I try to manually add a credit card, hitting the Save button does nothing.

When I use a credit card on a site, Firefox prompts me to save the card, I confirm that I want to save it, yet it isn't saved.

I have telemetry (every checkbox under "Firefox Data Collection and Use") disabled, but noticed that the datareporting/archived directory contains telemetry files. Is this expected, or does this indicate a bug that shows that telemetry is being sent?

The file paths have the format:

<profile dir>/datareporting/archived/2025-09/<unixtimestamp>.<uuid>.main.jsonlz4 <profile dir>/datareporting/archived/2025-09/<unixtimestamp>.<uuid>.events.jsonlz4

I have a question about using Firefox PDF Editor. I copied some text from a PDF document that is on my computer, by highlighting the text and then hitting Ctrl+C. The text copied onto my clipboard OK. Then I opened a blank PDF document in the Firefox PDF Editor and tried to paste that text into the blank document, but I wasn't able to do so because when I right-clicked on the blank document and then clicked on "paste", nothing happened. This apparently is because the word "paste" is faded-out in the drop-down menu (i.e., it does not appear in prominent bold print). Google's Artificial Intelligence seems to indicate that the technique I used would work (see screenshot which I've uploaded). But it didn't work, so can anyone please tell me how can I paste text into that blank document?

I am on endeavourOS (linux). Whenever I try to upload images for a profile picture to sites like youtube or X, the image becomes corrupted and doesn't upload correctly. It did this with whatsapp too and I had to use a separate app for it. Other posts said that disabling "privacy.resistFingerprinting" would fix it, but it's already disabled.

Attached below are an example of this bug and the contents of this image when viewed on a text editor.

It has been working fine - now I get this message:

I've tried making Google an exception, to no avail.

The page https://support.mozilla.org/en-US/kb/ai-chatbot lacks the list of data shared with the chatbot AI providers. It would be nice to know how it is done, how to review the data, and how pages can provide better data.
