Firefox Community 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.

Please assist or advise why Firefox seems to be slowing down my system by memory usage. I have a handful (6) of tabs open on 1 browser session and my system started slowing down so I checked my task manager and it shows that I have more than a dozen of Firefox instances open chewing up almost 90% of my memory.

Please assist or advise me on how to tweak my browser to perform better, and not to show ghost instances

Yahho search is on my home screen but not on my app list. I suspect malware. I use Bitdefender free for antivirus and scans sho no problem. I read that yahoo search can be hacked.What can I do

Hello, I think I may have asked about this in the past but cannot recall if I received an answer. Under Settings, I get the message "Your browser is being managed by your organization." This is my home computer and is not being managed by any organization. When I click for more information, it gives me a screen with the following information:

Policy Name Certificates

Policy Value ImportEnterpriseRoots

                         true

If I could get more information on this suspected error, or how to correct it, that would be great. Thanks!

i keep typing my issue that i want help with and you keep bringing me back to this page but offer no resolution to my issue. i simply want to know how to RESOLVE the data breaches thta firefox found . when i click on the link RESOLVE DATA BREACHES and it asks me for the email concerned and then says i need to log in to my firefox account. it simply repeats that it found 4 data breaches in one of my emails. but does not give directions of HOW to remove./resolve these breaches. so i am still left with the four data breaches. CAN SOMEONE TELL ME HOW I SHOULD RESOLVE THE DATA BREACH ISSUE.

When viewing a PDF, I selected some text, right clicked and chose the "Highlight Selection". The selected text was not highlighted. Instead, the "highlight" button on the top right corner pop up and the freehand highlight was triggered, while all my previous selection was lost.

I image this was not the intention of the "highlight selection", and I was also wondering if there is a shortcut for highlighting text in pdf.

I have included a website on the list of exceptions for deleting cookies when Firefox is closed. When I go to the website the icons on Firefox for it show "enhanced tracking protection off" and "You have granted this website additional permissions". This website uses cookies to recognize my computer and not to require a one time password. However, when I close Firefox despite the fact that the website is on the exception list, cookies are deleted and I have to keep re-entering the one time password. I did turn of the checkbox for deleting cookies when Firefox is closed and now I am no longer asked to enter the OTP after Firefox is closed.

I assume this is a bug. Does anyone else experience similar issues? Is anything I can do about it and be able to use the exception list as intended?

Thanks.

I've added https://x.com as an exception site but it is still blocked.

This is outright censorship which is something [edited] do.

Tell me how to fix your browser so I may access x.com again or I stop using Firefox forever.

The latest version of Firefox desktop has changed the "custom history" settings lumping forms and history with browsing history and downloads history. Before these were all separate options which was much more useful. How can I get the old menu back?

I don't want to just untick the higher menu "remember search and form history" as I want firefox to remember form and search history during a session - I often have firefox open for several hours at a time. But I do want to know when I close firefox that it will purge form history, but keep browsing and download history.

Please read below my emails to Ghostery support that describes the issue and the Ghostery response.

The issue is using DuckDuckGo in Firefox with the Ghostery add-on enabled, and changing DuckDuckGo AI settings.

Please let me know if there is a resolution available.

An FYI -

Ghostery Tracker & Ad Blocker - Privacy AdBlock 10.4.32 has an issue in Firefox with DuckDuckGo search engine Settings changes to AI Features, Chat to off, Assist to Never, then saved and shown working with a page refresh.

When Firefox is then shutdown and restarted the intended DuckDuckGo browser changes are not applied. Assist will still show a result in a search.

Proven by disabling Ghostery, again changing DuckDuckGo AI features and saving, shutting down Firefox and restarting, then searching with DuckDuckGo with no Assist displayed in result.

I can answer any questions you may have.

Regards, Long time happy Ghostery user Malc [edited] @gmail.com

Hi there,

Thanks for reaching out to Ghostery and bringing this to our attention!

We were able to reproduce the issue on our end, though with slightly different conditions. It appears that DuckDuckGo’s settings are stored locally in the browser. If Firefox is set to clear cookies and site data (either manually or automatically), this would reset DuckDuckGo’s preferences each time — even with Ghostery disabled.

Could you please check if the option “Delete cookies and site data when Firefox is closed” is turned off in your Firefox settings and try again? In our tests, DuckDuckGo’s settings were preserved when this option was disabled. It would greatly help to narrow this down.

Here for any further questions! Best, Ghostery Support

Hi Ghostery Support 2,

Thank you for replying.

Yes, the option “Delete cookies and site data when Firefox is closed” is turned on. When turned off and the Ghostery extension enabled, the changes to DuckDuckGo were saved and implemented correctly when Firefox was restarted.

I did find this.

In Firefox settings Cookies and Site Data, Manage Exceptions, I added "https://duckduckgo.com" and set Status to Allow. I also turned on “Delete cookies and site data when Firefox is closed”.

With the Ghostery extension enabled, the saved settings to DuckDuckGo were still active when Firefox was restarted.

But I do not think it wise to give DuckDuckGo an exception to use cookies and site data with no restriction.

Please keep me informed.

Regards, Malc [edited] @gmail.com

Hi there, Thanks for getting back to us!

Unfortunately, there’s not much Ghostery can do in this case. If DuckDuckGo saves its settings internally, there may be no way to keep duckduckgo.com out of exceptions while preserving those settings elsewhere.

You might want to look into third-party tools that support this kind of setup, or consider reaching out to Mozilla’s support team with this request.

Here for any further questions! Best, Ghostery Support Support Ghostery

I have accounts that will not work because they cannot access my location, My computer says all access is allowed, so is there something in Firefox that blocks my location?

Firefox 125.0.1 update breaks all self signed certificates

After the latest auto update I can no longer access any of my management screens on my private network with self signed certificates. This is a real problem. I have attached a couple error screen grabs, but ALL of themn are the same. The information link says there is no workaround!

So how do I recover access? Chrome works just fine ... so it is def. a Firefox problem.

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.
