Firefox Community Forum

wie bekomme ich dieses flieder wieder aus der darstellung. seit dem letzten update wird der Hintergrund in Flieder dargestellt. Es mag ja Leute geben denen das gefällt, aber mir sagt das überhaupt nicht zu.

Every time I open Firefox, and every time I click on a link in a Windows application that opens an internet link (with FF as default browser), even if FF is already open and running, I get the "this program needs your permission to make changes to your computer". How can I fix this glaring error? Mozilla no longer supports FF and I can't find anything about this on the Forum. I don't want to switch to a different browser, but I will if I need to. Please help.

I have had Refdesk.com as my home page for years. Firefox has now decided that it cannot find that site. Please help

Hi, I'd like to remove the rounded corners ( they are too big) everywhere in the Firefox browser. The suggestions I've found online aren't helping me. Do you have a solution for beginners?

My browser constantly tries to guess the language of web pages and offers me translations. These functions get in my way, I don't need them. How to switch off any translations (and translation offers) forever for all sites?

Home Page desktop bookmarks gone. Recent updates to both my deskyop (win 11) and laptop (win 10+) has erased all my desktop bookmarks. I tried numerous setting in Mozilla but still nothing. How do I get them back ?

Translation, may not be fully in line with your standard wording. The original message, in Swedish, below.

"When I seek information with Firefox, since some time I always get this error message from AVG: "Threat secured, We prevented your sonnection to thai.rontyig.come since it is adnagerous website. Threat category; URL.Blacklist"

Even when I search for AVG, the same msg is shown. If I use Chrome or AVG Secure browser, there is no error msg.

"När jag söker en uppgift med Firefox får jag sedan en tid alltid upp ett felmeddelande från AVG: ” Hot Säkrat Vi förhindrade din anslutning till thai. rontyig.com eftersom det är en farlig webbsida. Hotkategori: URL:Blacklist ” T,o,m, om jag söker på AVG visas samma spärrmeddelande!

Om jag t.ex. använder Chrome eller AVG Secure browser

Kind regards Ulf Hj.

There doesn't seem to be an "Other " or "Additional Options" category, so if Settings isn't in the correct category, please tell me where to post this. TIA

I want to be able to create multiple default 'pinned" tabs that will appear every time I open up a new window. Is that possible? If so, how? Again, TIA

Hello everyone,

I'm looking for ways to troubleshoot streaming video issues in Firefox. Sometimes video playback can be affected by browser settings, the internet connection, or device performance.

What steps should I follow to identify the cause and improve playback?

I also came across Selvydia while researching IPTV and streaming services. Would browser troubleshooting differ depending on the streaming platform being used?

Thank you for any practical suggestions.

I've been using firefox for a little while- maybe three months now. I'm no expert on any of the config options. I run firefox using the built in VPN that my friend showed me how to enable, and I've been using it since. But now, as of roughly today, whenever I enable the VPN, no websites will load. At all. When I turn it off, they load instantly. But whenever I turn it on, it just gets stuck loading forever and ever, never actually getting anywhere. I tried enabling network.dns.disableIPv6 in the config page, because that's what I saw on a mozilla support page- nothing. Didn't do anything. The browser.ipprotection.enabled is still on, and I didn't change anything in settings. There was a firefox update very recently, but everything still worked with the VPN on. I just updated my computer, but I don't think that's it either because it wasn't loading things earlier today either. Not sure how to fix this. Please help?

Hi Mozilla team & community,

I am facing a persistent video playback issue specifically in Firefox (latest build on Windows 11), while the exact same stream plays flawlessly on Google Chrome and VLC media player.

When attempting to stream high-definition HLS live content from my media portal site (https://bidarn.com), the video stalls and buffers every 10–15 seconds. Upon inspecting the Firefox Web Developer Console (Network tab), I notice frequent `NS_ERROR_NET_TIMEOUT` errors during the loading of .ts media chunks, along with occasional CORS flags during concurrent HTTP requests.

I have already completed the following standard troubleshooting steps: 1. Disabled Enhanced Tracking Protection for the domain. 2. Started Firefox in Troubleshoot Mode (Safe Mode) with all extensions turned off. 3. Cleared all cookies, site data, and browser cache. 4. Tested with hardware acceleration toggled ON/OFF.

Unfortunately, the segment fetching latency remains high in Firefox.

Are there specific parameters in `about:config` (such as adjusting `network.http.max-persistent-connections-per-server` or expanding `media.cache_size`) that can optimize how Firefox handles parallel HLS segment fetching?

Any technical guidance or network config recommendations would be greatly appreciated.

I've tried troubleshoot mode and the problem remains, I have no idea what I did and I've spent a good hour of research and found nothing to help with my problem, I'm at the end of my witts. The problem is most visible with google docs, but it goes beyond, like these huge lines in the corner of boxes like the one I'm typing in now (see screenshots).

Not a question just feedback but the new UI you made for the browser in the new update looks really bad and really sucks I don't know why or what anyone was thinking designing it. The blocky styles were fine before not gonna lie. :/
