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?

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

So my internet speed is around 100 Mbps but i only get 10 to 12 Kbps when download a small file, idk why because i tried using ethernet and it is still 10 to 12 kbps (sorry for bad english)

Several weeks ago, I was attempting to upgrade from Windows 10 to Windows 11. In the process, I deleted Firefox (using Revo Uninstaller) and then reinstalled it, downloading it from the Mozilla website. Unfortunately, it didn’t run, giving me, at different attempts, different error messages. In the time since then, I have read many suggestions from many different websites and I have tried some of these suggestions, all with no success – until today. I have just completed the suggestions made on https://support.mozilla.org/en-US/questions/1327628 and Firefox is now back, working. I am happy and grateful, but not finished. None of my personal data came with the currently functioning version of Firefox. Since the re-emergence of Firefox, I have been reading several websites dealing with copy, backup and restore of my Firefox profile. Right now, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ shows 5 folders: Two of the folders show 11/11/24 as the date modified (probably the date of the download from Mozilla). The folder 0dppjrfa.default contains one file, times.json, dated 8/11/2020. The other folder, ru82tlj5.default-release, has 97 items, most dated 11/11/2024. The remaining three folders are all dated 12/2/24 (today, as I write this). One folder’s name ends .default, the second name ends .default-release, and the third name ends .default-release-thirteen digits. The question that I am asking here is what do I do next to, hopefully, bring back the personal date I had with Firefox before my updating to Windows 11. Should I delete the folders dated 12/2/24? What, if anything, is the significance of the folder whose name ends in 13 digits? I’m hoping someone will be able to tell me how to fix these Firefox problems. And if I can, then I hope to be able to do something similar to help me bring back Thunderbird as well. Thunderbird became unfunctioning at the same time as Firefox. Thank you.

I had a lot of tabs open in Firefox, and they always stayed there even after restarting my PC. But suddenly, all of my tabs disappeared, and I can’t recover them using “Recently Closed Tabs.” Can I get them back?

Not sure I selected the proper category, but I've been coding websites since for longer than I like to admit.. (About 1998 memory serves me right..).. Anyhow, at this point I maintain 3 websites.. Here's one of them: https://www.pbl-sn3.com As you will see there are many pages involved.. I used to able to right click on a photo or graphic and Firefox would tell me what it was, its filename, and even it's size.. But no more.. This was a really handy feature that kept me a Firefox user ever since I discovered Firefox..

Now, instead of right clicking on it (so I can find it easily on my PC using a great little program called "Everything" (see https://www.voidtools.com/ which is amazing in its own right..), I'm stuck viewing the Page Source, finding the file in all the jumble of code, etc. etc. etc... (Yeah, I can right click on the image and open it in a new tab, but it tells me nothing about its SIZE either.. Dang!

So am I the only guy that's ever complained about this? (I recently downloaded Google Chrome which appears to be a less-than-perfect knockoff of Firefox and also lacks this "feature".. But my bank likes it whereas they would no longer allow me to do online banking with Firefox.. A pesky but unrelated issue here, I know..)

Anyhow, if there's a quick fix for my problem, I sure would appreciate a how-to implement it! Thanks for "listening"! - Ol' Bill in California

I can't watch Twitch live stream and videos after updated.When I watching live stream on Twitch, the stream start showing some old tv effect but in colours green. I thought was Twitch problem, then I changed to watch video from my college by using their website. But it still has that effect. But I can watch Youtube videos with no problems. Then i changed to use Microsoft Edge to watch Twitch, surprisingly with no problem. I already updated to the latest version in Firefox. Can anyone help me Please. Thank You

I have downoloaed Firefox offline installer (a .xz file) from here:

https://download-installer.cdn.mozilla.net/pub/firefox/releases/139.0b9/linux-x86_64/en-GB/

I have also downloaded a .asc file, presumably a pgp signature.

Now both files are saved locally in my computer.

Assuming Linux latest release, how do I verify the contents of the offline installer file (.xz) from the Linux Terminal? I have install gpg tools. And commands like ```gpg``` are available.

What I did so far:

 gpg --show-keys --with-fingerprint firefox-139.0b9.tar.xz.asc

with this output:

 gpg: no valid OpenPGP data found.

Do you really want us to verify the contents of the installers you provide? A sha256 sum would be great, though not as secure, for when the GPG predictably fails for the ordinary user due to its huge and useless complexity and bureaucracy.

Ok, this is a weird one.

I can't load https://duckduckgo.com. It breaks search in a new tab, but I also can't visit it directly from the url. The tab simply does not load.

I've cleared cache, cookies, and extensions. I've refreshed Firefox more than once.

I can visit https://html.duckduckgo.com. I can visit https://lite.duckduckgo.com.

However! In a private window, I can visit https://duckduckgo.com It still breaks in a secondary normal window.

No other site appears to be broken.

First of all, why are there two Other Bookmarks folders? When I add a new bookmark, my routine is to open Manage Bookmarks, drag the new bookmark to the second (lower) Other bookmarks folder, then choose Sort > Sort by Name. I have also tried A > Z Sort Order. The sorts work within the Manage Bookmarks window, but they are not saved automatically, and I do not see a way to save them manually. Also, if I go to the Other Bookmarks folder on the far right side of the Bookmarks Toolbar, I have to scroll down to the bottom of the list to see my new bookmarks. They are not in ascending alphabetical order the way I want them.

How can I stop advertisers from changing my 'Settings' fields 'Home page and new windows' to their URL which brings up their page before I can enter my password? I'm on Linux Desk Top.

I can no longer access my local TrueNAS server nor router via Firefox. My current version is 133.0.3. Safari has no trouble. Firefox gives no warning, no Advanced button, no option to bypass security. All I get is: "Unable to connect An error occurred during a connection to 192.168.0.102.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."

I have tried so many settings, troubleshootings, workarounds, I can't begin to list them. It happens in troubleshooting mode. I have created SSL certificates on the server many different ways to no avail. I'm thinking I will have to abandon Firefox with it's obscure, no-way-through security. But I wanted to ask for help first. Please help.

I've been using FireFox to login to nytimes.com for many years. Recently, the nytimes.com website hasn't been working properly. It works fine using Edge.

Symptoms are: (1) The zoom level at login and the zoom on going from page to page is very inconsistent. (2) Clicking the Account button does not open the account settings page. Instead it causes the screen background to become grey.

I restarted FireFox in troubleshooting mode, but this did not improve the behavior. I have a single extension (Adblock). Disabling Adblock on nytimes.com also did not improve things.

Some icons and images all over some websites are being displayed wrong, I've tried refresh and reinstallation without success. I'm running Windows 11 latest stable update. Ryzen 7 5700X RX 6750XT Monitor: Samsung Odyssey G60SD

I also tried disabling hardware acceleration and clearing cache, nothing worked.

I am trying to export/import my book marks from one macOS computer to another (intel to Apple silicon), however, all of my imports and restore attempts fail. My last restore attempt failed with the following message: Firefox Unable to process the backup file. Any other suggestions?

The screenshot function seems to have a bug. The function works as far as selecting "save full page" or save visible" but the image download never happens. Version is up to date and I have restarted but the issue persists.

For the last month or so every time I restart Firefox (macOS 15.1.1) it asks for the master password, which I have saved in a third party password manager. Every time the prompt pops up I use my password and it won't accept it so I have to reset my password. This week I deleted the app from my computer, rebooted, redownloaded Firefox, and reinstalled it without any change in the behavior. Anyone have any ideas?
