Firefox Community Forum

I was having an odd issue the other day, that I now solved by comparing the settings on a working Firefox profile with mine.

For some reason, on one of my multiple Firefox profiles a list of web apps wasn't working. Among them were Discord, Miro Board, and Google Pay. I was suspecting that they all had the same issue, but didn't know what it was at that time.

The security settings were the obvious suspect (Ad-blockers, DNS, HTTPS enforcement etc.) because clearly something was being blocked, however nothing helped. The solution was in the Network settings. (See screenshot) I was using Manual proxy settings from the time I messed with I2P networks (or something similar).

I am not sure why having a proxy to localhost (127.0.0.1) on HTTP would somehow cause very specific major apps to stop working, while others keep working fine, but it happened to me anyway.

For anyone in a similar situation, with those particular apps not working, check your proxy settings.

I have recently installed the containers extension and have been having a bit of trouble with one site (the others are fine), which seems to originate from the manner in which the site is structured. As it references new pages, they are often in a different URL. For example, you start in login.site.com, which then tries to load dashboard.site.com, but it fails authentication on dashboard.site.com because it opens in a different container. Which then tries to open the login.site.com page again, which displays the login page, but showing it tying to complete the original authentication. I have tried to add each step along the way, but without success. Is there a way to overcome this?

I am so tired of the stupid banner popping up every time I put something into full screen, that says "press escape to exit full screen".

Is there a way to disable that?

Hmm. We’re having trouble finding that site.

We can’t connect to the server at yourewardcard.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

When I click on a link, it opens in a new tab. I do not want the link to open in a new tab but to open in the current tab, how can I change to this please? Thanks, Andrew.

No sound, thought speakers went bad. Bought a microphone and still no sound. How do I do Doxy.Me or Zoom without outgoing sound?

I keep getting a triangle deal on Firefox that indicates I need to add the "permission request for Firefox extensions" from Mozilla. Is this something I need to install or just information regarding extensions. From reading about this it doesn't appear to be safe because it can access and change nearly everything? Please respond Thanks, Larry at [email address]

macOS 15.6 Firefox 141.0.3 - my preferred browser

I've seen a number of posts regarding this problem since the Firefox 141 update. I've tried a number of suggestions, although my problem seems slightly different.

I can apparently login to reddit OK but when I try to access a subreddit thread, a warning comes up - see image.

I have cleared Firefox site data, cookies, cached files, etc - problem remains.

I have restarted Firefox in Troubleshooting mode - problem remains, so not an extension.

However, https://old.reddit.com has no problems with Firefox, lets me access threads, etc and comment.

No problems accessing reddit with Safari or DuckDuckGo browser.

Hi: There is no Refresh Firefox tab. I go to Help More troubleshooting information. Like I've done a million times. And for Diagnose Issues there's only a Troubleshoot Mode and a Clear startup cache tab. No Refresh Firefox tab. I did not want a new profile. I did not want additional profiles. This has messed everything up. Firefox is not working. Thank you

i keep getting Firefox crashes and i also get Firefox already running close firefox i have the latest version i do not understand why please help thanks
