Firefox Community Forum

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.

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.

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?

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?

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

'We've detected a problem with your cookie settings. Enable cookies

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

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.

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?

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.

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?

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.

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 just learnt that the mozilla firefox terms of service have been either updated, or previously included, a clause of sorts that states that any content uploaded to mozzilla is automatically given a royalty free worldwide license to mozilla itself. Does this apply to content such as add-ons only or does it apply to things uploaded to other websites(such as social media, forums, etc)

About once a week or more, a very small FF icon will appear on my desktop after startup. It will have a string of letters under it, like this one: hqWyUevN . I have never clicked on these things and always pitch them into the trash bin. But I do wonder what it is, what it means, and if it's a security issue of some sort.

Please speak slowly and use simple words. I'm not all that tech savvy.

Thanks!

Everyday I get pop ups usually for car parts, all for ICE cars and I have an EV these days . . . . . Please stop sending them. Is that possible? Regards, [edited email from community support forum]

I keep getting pop-ups in the right lower corner from "mozilla firefox" (not sure if they are legit). They will say: "zeus.2020 trojan detected" or "virus detected" or "system is infected", etc. All have "Mozilla Firefox" in the upper left of the pop-up, and "via rgfirewall.xyz" at the bottom. Is this truly legit, or is it just a nuisance? I've just been closing them with the x or dismiss buttons.

Attempting to upgrade and recommission an old HP laptop not used in several years. Currently running Firefox Version 41.0.1

Any queries to legitimate websites such as Google or Mozilla, return a "This Connection is Untrusted" display screen. Firefox security settings have been changed to lowest security, and problem persists.

It isn't that Firefox isn't reaching the websites... it's that some security setting recognizing the security certificates (like Mozilla's) is broken... and I can't get past it... even to be able to download a new browser version.

As creator of retroonline.net. We recently noticed Firefox have limited value size in IDB which Chrome and Edge do not have. This limitation prevents big games running on Firefox despite Firefox has the best performance on WASM. Will there be a proper way to change this limitation or plan to remove it?

bsky.app cookie continues to be loaded on computer even after I continually delete it, privacy set to strict and blocked under "managed exceptions, why is it being reloaded when I don't access the site. None of the sites I access are linked to it, only visited once and if this alternative to x continues to set cookies, how can I permanently block it, thought the exceptions list was supposed to keep blocking it. So far it's come back three times, I'll screenshot it next time and attach.
