Firefox Community Forum

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 I had to refresh Windows 11 on my Dell desktop. It defaulted to McAfee antivirus. I uninstalled McAfee and reinstalled Norton 360 which I had before. I reinstalled Firefox. I have version 123.0.1. I imported my FF bookmarks after exporting them from another computer. Now, FF remembers my IDs but not my passwords. When I log in to a website, FF offers to save my password and when I click yes it pops up a bubble saying "Password saved!" However, next time I go to that website, although it remembers my ID, it does not recall my (supposedly saved) password. In this support site, I see most users with this problem say FF will not remember either their IDs or passwords, whereas FF remembers my IDs, so my problem may be different. In FF help, I see that another password manager could be keeping FF from saving passwords. To the best of my knowledge I have never used another password manager. What is keeping FF from saving my passwords, while remembering my IDs? Is there a Windows Registry setting or a FF About:Configuration setting I need to change? Is re-installing FF a last ditch option?

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

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?

Hi I recently was hacked unfortunately due to a stupid screw up involving a person who had hacked a friend's account and had me download some malware disguised as a "game he worked on" and managed to get all my passwords stored in Firefox (spent 9 hours straight changing all 200 of them and wiping the laptop). I believe I am misinterpreting some things on how secure the storage of passwords are for Firefox as I thought using the "Primary Password" function would encrypt everything properly. The hacker proved he had them unencrypted sending some examples to me to flaunt.

Was he able to attain access to the passwords due to me already having firefox open when I was compromised (even if the primary password is asked before entering each password?) Or is there some issue with firefox not storing them properly? Or is there some other less know issue with windows or edge or something "stealing" the passwords and storing them in an unencrypted file without me knowing?

This whole thing makes me feel less trustful of firefox to say the least and while the hack itself was my fault I just want to know if there was something else I could have done other than using keepass or some other password manager to exclusively store passwords (which is what I am going to do now and probably should have been doing)

TLDR - Primary password did not stop hacker from seeing passwords - Any clarification on whether this was my fault in trusting it for such things or if there is an actual issue with firefox's approach

Thanks for any help or clarification.

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.

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.

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 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.

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.

Issue summary: I lost over 100 sites listed in the Cookies and Site Data section when I simply removed a few websites in the Enhanced Tracking Protection section.

Under the Browser Privacy section, the two subheads, "Enhanced Tracking Protection" and "Cookies and Site Data" serve two distinct purposes—as I understand. Enhanced Tracking Protection will automatically add the URL of a webpage (that you currently have open) to the Enhanced Tracking Protection screen whenever you disable the shield in the search bar. This will turn off tracking for that website until turn you it back on. You can also manually add websites to the Enhanced Tracking Protection screen if you have mulitples to add. This whitelist will stay active until you delete them or click on the shield to turn it back on.

The Cookies and Site Data section further down, allows you to create a list of sites that you want to BLOCK, ALLOW FOR SESSION, or ALLOW cookies and site data to be used, and retained or not. This differs from the Enhanced Tracking Protection section.

Today, I wanted to delete one of the websites listed in the Enhanced Tracking Protection, and did so manually. But since there were only a couple listed (I rarely add to this screen), I simply clicked on "Remove All Websites" instead of "Remove Website." Unfortunately, when I went down to the Cookies and Site Data list (which I use all the time) to add a new URL today, my entire list was gone! I did not remove or enter anything in the Cookies and Site Data screen today, prior to using the Enhanced Tracking Protection screen.

As you can guess, I am sick because I had over 100 sites listed in the Cookies and Site Data section, and lost them all when I removed the few websites in the Enhanced Tracking Protection section. I don't know why or how this happened, but it is worth noting that I did just update Firefox this morning to vs 125.0.2 (from 124.0.2). My list is gone, but does anyone have a reason why it happened and is there a way to prevent that in the future? Or is it some kind of bug with the latest release or an earlier one. (I haven't opened the Enhanced Tracking Protection screen for a long time, so it could be from any past release.) Sorry I don't have more info than that. Any solutions would be appeciated.

When we log into our Yahoo email, there's a small triangle (see screen shot) next to the padlock on the address bar that says "connection not secure".

Not sure what to do to get rid of it.

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 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?

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 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?

Having tried all pointers to how to display this data, I give up and present my case here: In a banking app, the login field is blank and requires me to enter the correct Login ID. This works fine. However, if I double click on that field, an option is displayed, happening to be my email address, which will not work in this case; a numeric value is required.

So, knowing a prompt is enabled, I have entirely failed to get 'it' to save the correct ID. I have also find a place in Firefox settings where I can see and modify the value that comes up. I do however remember doing exactly that for some other site.

So, as I have said, I cannot find this in the Passwords nor the Settings pages. What am I missing?

Help would be much appreciated.

When I visit the web site virtueonline.org using Firefox browser, the Disqus comment section does not appear below articles on the site. Sometimes, when I go in and out of the article, the Disqus comment section will appear, but not always. When I use Microsoft Edge, the Disqus comment sections appear.

My FF version 126.0.1 browser history file size is stuck at 10,240 KB. Until recently it was 54,000 KB and change. I would like to get it larger. I've tried all the recent help postings relating to places.history.expiration.max_pages, places.history.expiration.transient_current_max_pages, browser.history_expire_days, browser.sessionhistory.max_entries or browser.sessionhistory_max_entries, and so on. Nothing seems to be able to change the "places" file size. Anyone have any more info on this topic?
