Firefox Community Forum

I can access Chewy with Safari, but not with Firefox. So the problem is not with my Mac settings and the problem is not with Chewy, the problem is with Firefox. Please address and fix it.

Hi folks, my primary password suddenly stopped working when trying to look at saved passwords today. I've changed it to a new one, needing to type in the old password to do so. That worked, which verifies I had the correct password to begin with.

I then updated the browser to the latest version. When I type in the new password on startup of Firefox it works fine to reopen all the old tabs.

However when I go to look at any of the saved website passwords, the problem reoccurs again. I type in the new password but the box shakes, refusing it.

How can it be that the primary password lets me in fine when starting up Firefox, yet I get the shaking login box when I try to look at any saved website passwords? Surely if the primary password works for one it should work for the other?

Thank you, Shane

since v150 came out ive been having an issue where i get a flash of white on start up if i have Homepage and new windows as Firefox home with a wallpaper... i have re-installed firefox and tested it as default and it still happens. seems the wallpapers have a delay till it displays properly.

Many URLs and hosts automatically reload pages. For example, when I am reading a multi-page article and am several pages in, the page often reloads and I have to start all over again and try find the place where I left off reading. "Stop Auto Reload" is a Firefox extension that is supposed to allow the user to stop the auto-reloading that many URLs and hosts execute, but it does not always work. It seems to work on some sites, but not on others. I have not found any other extensions so far that address this. Any assistance with this problem is greatly appreciated. -Neil

It was nice when FF was simple to use....unimcumbered with all the options...like the latest...profiles.

Why? It's getting to be as complicated as E and C..you don't need all those options - that's why I use FF.

Get rid, or allow the user, to pick and choose, and dump the unwanted stuff from cluttering the tool bar and other options. Just a suggestion that can be made to FF any longer. Use to be they'd welcome feedback.

Issue Summary: When disconnecting from a corporate Cisco AnyConnect VPN on macOS, Firefox completely loses its internet connection and throws network errors. Other browsers (Chrome, Safari, Edge) continue working perfectly on the home network. Standard troubleshooting steps—like clearing Firefox's DNS cache, changing proxy settings to "No Proxy", turning off DNS over HTTPS (DoH), and flushing system DNS—do not resolve the issue.

Root Cause: Cisco AnyConnect locks low-level socket configurations and routing rules within the active Firefox user profile (prefs.js). Even after the VPN is disconnected, Firefox remains bound to the dead corporate pipeline, a behavior that standard settings menus cannot override.

Proven Solution: The only way to clear the corrupt VPN socket locks is to completely reset the internal profile architecture:Open Firefox, type about:support into the address bar, and press Enter.Look at the top right of the page and click the "Refresh Firefox..." button. Accept the prompt. Firefox will close, securely back up your bookmarks/passwords, generate a fresh profile, and restart.Internet access will instantly return to normal. (Note: You will just need to reinstall your extensions afterward).

All the tabs, in both my profiles are constantly crashing. I cannot keep at a task for more than a few minutes without needing to restart the tab. Is this a setting problem? I've cleared the cache, and reset Firefox, to no avail. Thank you for any relevant advice and/or assistance.

I tried reinstalling firefox because I wasn't getting notifications from websites. I'm not getting notifications now either. I checked my computer settings and reinstalled the software on my Mac Book Pro 2012 version 10.15.8.

I work at a small daily newspaper chain, and our website CMS is both archaic and homebrew. I only work with it sporadically, and Firefox is the best option for maintaining it.

This morning, I got the regular "Are you sure you want to delete this?" dialog box (pretty sure it's a Javascript call) with the additional check box of "Do you want (URL) to not prompt you for this any longer?" (or words to that effect).

I thought, "Great, one less click" and made that selection.

But now when I want to delete an item off the articles list, it doesn't delete at all.

I'm pretty browser-savvy, but I don't know how to re-enable that option. Any ideas?

I'm on a private home network with an internet connection. When I try to use Firefox it displays a message saying "You must log in to this network before you can access the internet".

Many websites, e.g. Amazon, won't load and an 'Open network login page' button is shown. When I click this it takes me to a Mozilla page talking about Captive Portal, but there's nothing about how to stop this happening and access those websites.

Other browsers, e.g. MS Edge, or Brave, have no problem access these websites.

How do I fix this problem?

Pretty simple. Every time I click any "news" link on my home page in Firefox it always runs into a pay wall. This is crap as these losers get a hit count to their site, get to load ads (for some people), and so on but I don't get to read the article. And who know s what kinda crap they are dumping into my cache. This needs to be fixed or the "feature" removed. This is basic privacy shit not included in a browser that tries to brag about privacy features.....

I'm reposting a question already opened here because a moderator suggested to do so. Actually I though I was posting to the international forum from the URL...

I was trying to access a local HTTPS website of an embedded device (a Siemens S7-1500 PLC) that is using a self-signed certificate, but was unable to go on (attached image #1, in Italian language) due to the the SEC_ERROR_REUSED_ISSUER_AND_SERIAL error. I've browsed a similar PLC webserver in the past, so the fact that the device exposes a similar certificate serial number is not so strange for me, considering also it's self-signed.

The problem is that I cannot follow the instructions of the Mozilla knowledgebase here because I'm not able to identify the correct certificate of the website!

In the attached image #2 you can see that the connection is detected as not encrypted, I suppose because only the form part of the HTML that is posting the data using HTTPS while the rest is using HTTP, but I'm not sure. If I click on the padlock icon (attached image #3) the info about the current certificate is not displayed.

Then I went into Tools > Options and searched for "certificates"; as you can see in the attached images #4 and #5, neither in the Servers tab nor in the Authorities tab I can find any item that is related to 192.168.10.2 (the webserver IP address) or Siemens (the embedded device manufacturer). But unfortunately the error persist! Initially there was a 192.168.10.2:443 line in the Servers tab and I removed it and restarted Firefox, but it didn't solve, so at the moment the situation is the one depicted by the attachments.

I had to use Microsoft Edge to access the website, but I would like to solve this issue and use Firefox instead. Is there anything else I can do to bypass the error? Why doesn't the error page provide a way to correctly identify the wrong certificate using its fingerprint and/or name? Or, maybe, is there a way to disable this check for local IP addresses or for items in a whitelist?

Thanks for your help.
