Hello! After a clean install of Windows 11 24h2 Pro, Mozilla Firefox is unusable. It takes about 2 minutes to load a page which is abnormal. I remember I had the same issue when I first installed Windows 11 23H2 Pro and that was resolved somehow but it was 2 or 3 years ago and I've no idea what the solution was back then. I've tried some basic stuff including Test suggestion which of course didn't resolve anything as almost all of them are referring to cleaning cache, reinstall Firefox etc and it literally has nothing to do with my situation. Any solutions?

Hello Firefox friends o/

Anyone knows how do I make https://yandex.com my default search engine? (in the top bar of the browser). I have attached a screenshot of my settings page. Please have a look at the suspicious lack of an "Add" button 🤔. Despite my efforts, the drop-down menu will not show the available options in the screenshot, you will have to take my word for it, the only available options in that menu are: Google, Bing, DuckDuckGo, eBay and Wikipedia (en).

P.S. The settings page in Firefox must change really often, as I seen so many people suggesting many outdated methods online.

ATT.NET is blocking my access to ATT/Yahoo email from my ATT.net account using Firefox ''but not using Chrome?'' I have stopped all tracking and cookie blocking

"Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over."

At some point Firefox stopped allowing me to drag tabs or bookmarks around. This includes moving tabs around in their order, dragging a tab into a new window, dragging tabs into bookmarks, moving bookmarks around in the browser. I can't drag them around in 'manage bookmarks' either. I can still open and create bookmarks; they are simply much more difficult to place where I want them.

I believe this happened with the last update but it's not a feature I use all that often so it could be older.

I have opened Firefox in safe mode and had the same issue. I have turned off the computer several times since this began.

Any help would be appreciated.

Over the past few days (Oct. 18, 2024) the green Download button has been missing. When can we look forward to the fix? Have uninstalled & reinstalled twice. Thanks.

Hello,

For a few days now I've been unable to use Google tools via Firefox (I can't tell if this is due to an update or not).

As soon as a document (usually an editable or navigable area) is opened on the page, it appears completely black. Interactions work correctly at first glance (it's possible to click, write, interact with content that isn't displayed. The problem seems to be purely visual.

I've encountered the problem in all Google Sheet or Docs documents (including when I'm making a new one) and on Google Maps, regardless of location (in the case of Google maps, a notable point is that the map is displayed and then turns black after one or two seconds).

I don't have this problem on another browser, I have it in PM.

Do you have any ideas on how to find the cause and fix the problem?

Have a nice day!

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

I am a bit confused about how to keep updating FF on my Windows 7 PC, given that after March my current version (115.17.0esr) may not work as intended. Until now I've always updated manually by downloading a small 343KB installer file that updated FF without changing any of my settings, logins and bookmarks. Hoping to simplify updating, today I set updates to "Automatically install updates (recommended)" with sub-option "When Firefox is not running". But just now a FF notification informed me it was unable to update automatically and provided a link to https://www.mozilla.org/en-GB/firefox/enterprise/?reason=manual-update. From the dropdown there I chose "Windows 64-bit" > "Firefox Extended Support Release (ESR)". The download is a 64MB file.

Since this seems to be a new installation and not a simple update, can I be sure it won't overwrite my current version and leave me without settings, logins and bookmarks?

AI "summaries" or "explanations" have been popping up in front of actual useful text that I want to read. How do I disable this AI summarizer or turn it off? If this removes an AI chatbot, even better.

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?

Hi

I've just booted my machine and opened Firefox, only to be presented with a completely fresh install.

All my settings, bookmarks and history gone. It was fine yesterday when I closed it and powered down.

I'm running Kubuntu, I've checked the .mozilla folder and nothing...it's like my profile has just been overwritten.

Not happy at all, I'm starting to dislike Firefox.

Can anyone offer any help or advice please?

Thanks in advance.

My system memory is reading at 57% right now in task manager, that the vast majority of that is being used by Firefox.

Why?

Normally, this would be called a flaw in the program, not the user, as all I have done in regards to settings is "keep tabs previous open when re-opening Firefox" and "Do not automatically update" because Firefox took it upon itself to not re-open my previous tabs on the last update.

Why is this program eating up all of that memory? I have "Firefox (15)" in Task manager under "Apps" and then 13 more instances of Firefox in "Backround Processes"

Wtf?

I currently can't stream anything, and this keep getting this message: Widevine Content Decryption Module provided by Google Inc. will be installed shortly,but it never installs.

I have a macbook air and am currently running macOS Sequoia version 15.0.1.

I tried uninstalling and reinstalling, removing extensions, clearing cache and data, unchecking and then checking back again the reproduce drm protected content but nothing has worked.

how to permit

This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

With Firefox 135.0 i cant reach google.com but google.se i can.

I make daily images of C: and today i managed to go back one day to 2025-02-06 but accidentally chooses 2025-01-06 and with the older version of firefox i could reach google.com

I have tried to delete cookies. DNS over HTTPS off. No proxy in connection. Add-ons off but to no avail.

Good day, The issues that I am encountering are explained below. The solution found after hours of research is uBlock Origin : https://ublockorigin.com/. Do you know which filters and rules should be applied to exclude the Wikimedia Foundation and all of its derivatives from the results provided by my search engine? Please share your knowledge. Sincerely. ________________________________________________________________________________________________________________________ I am utilizing Firefox ESR 128.10 desktop version on the Linux operating system. I wish to conduct research on the internet, utilizing the Startpage search engine. I would like to exclude the following sites from my search results: wikipedia.org, the Wikimedia Foundation, and any affiliated websites, regardless of the language or location settings configured.

What is the correct approach to establish a customized Startpage search profile excluding all Wikimedia Foundation sites? What is the proper setting to create a persistent and customized search engine configuration that excludes all Wikimedia Foundation domains even after an operating system update or reinstallation? Is it permitted to manually manage a customized search engine?

I have been advised to utilize an add-on or create a dedicated profile.

What would be the most suitable solution in my case, and the one that will be the most effective and stable ?

It is unfortunate that mozilla-firefox does not appear to offer a 'blacklist' or exclusion list feature, as that would be the most direct approach to excluding the Wikimedia Foundation websites from the search results.

I thank you kindly for all of your suggestions and responses to come. ______________________________________________________________________________________________________________________
