Hi All, I want to block traffic on firefox externally for managed devices via Intune, following the import of the ADMX/ADML files into intune.

I have set '\Mozilla\Firefox\Exceptions to blocked websites' to the following

• //*.mydomain.com/*

which works, however, I also want to add hosts that are only resolving on IPs and not DNS. I can add specific IPs if known, but is there a way I can allow IP ranges? Ie

• //10.10.*/* (this doesn't currently work)

Of the included screenshot, only the wildcard for mydomain.com and the specific IP currently work

If there is a better way to do this via intune for firefox only, please let me know.

Thanks

When I try to connect to Mosquitto WebSocket from other browsers like Brave and Chrome, it connects, but in Firefox, it fails with a 'Connection Failed' error. The issue is related to HTTP/1.1 and HTTP/2, but how can I solve this problem?

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.

My Firefox started crashing a lot recently. Dozens of tab crashes within the span of just a minute or two are not uncommon. Sometimes, the entire browser itself crashes. Usually, the reason given is a vague EXCEPTION_ACCESS_VIOLATION_WRITE or EXCEPTION_ACCESS_VIOLATION_READ. I should note that in my case, the crashes affect most of the browsers I use, but they do not crash nearly as often as firefox does.

I've tried using it without any extensions (clean install), and with hardware acceleration disabled. I've run a RAM test also, which showed no issues. Disk check also indicated no issues. I installed windows 10 and even windows 11 on the secondary hard disk, but the issue persisted. I've also tried forcing my discrete/integrated GPU to be used solely as the display adapter, but the crashes still persisted.

When using firefox on ubuntu, the crashes do not happen, strangely. There was only one instance that I noticed the crashes on ubuntu, and that was when I set my discrete graphics card as the exclusive display adapter, from the BIOS settings.

Anyway, nothing really sticks out as the root cause. Wonder if someone is able to decipher anything from the crash reports below https://crash-stats.mozilla.org/report/index/bp-6927a483-6c22-4830-b057-1413e0241104 https://crash-stats.mozilla.org/report/index/bp-42b9b1f5-5820-4ed9-9c52-30c8e0241104 https://crash-stats.mozilla.org/report/index/bp-0b92e804-00e8-4515-9129-3b5db0241104 https://crash-stats.mozilla.org/report/index/bp-d27cdb0b-3e38-4507-925b-09ce30240914 https://crash-stats.mozilla.org/report/index/bp-fa6b0609-ae19-4a66-a81d-078040240911

For no apparent reason I suddenly found that I could no longer browse via duckduckgo or Google (but could through Edge!). The on-screen response just informed that the sites were not available. I had no idea what could have caused this but a Microsoft fault search identified it is a DNS problem. I prefer to use the duckduckgo and need to resolve the DNS situation. Is this a Firefox problem, and if so, how do I fix it while still maintaining security?

hi I am getting black pages for certain shop websites connected to cloudsflare/shopify on most of my pc browsers except for a private browser called librewolf

If I inspect the webpage source This page is in Quirks Mode. Page layout may be impacted. For Standards Mode use “”.

I wonder if it is tracking related

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:8080.

   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.

HOW TO CONNECT

My YouTube videos are very choppy and keep buffering. This happens no matter what resolution I choose. My internet connection is fast according to speed tests I've run. I'm using the latest version of Firefox on a MacBook. I've tried clearing my browser cache and cookies, but that didn't help. Can you suggest solutions to fix this problem?

I use private browsing as my default and really only open regular tabs when I want to save something for a long time. My private tabs often close on their own at random times when I'm tabbed out with the Firefox app open in the background. If it happened every time I tabbed out or once a day or something I would assume it's a feature, but recently my tabs went about a week without closing and since then they've been closing when I'm tabbed out for 20 minutes. What's happening?

Hi there,

I am using Fennec from F-Droid (build 1340020). I noticed that many Brahmic scripts on webpages are shown as boxes. I don't recall seeing this in early versions maybe years ago.

Notably all major scripts in India like Devanagari, Tamil, Telugu can not be rendered. However, Odia and Sinhala scripts are shown fine. Outside India, Tibetan script cannot be rendered either. However, SEA scripts like Thai, Burmese are fine.

Moreover, if I copy these boxes to the search bar, the actual content can be shown. The tab view can also show the title of the webpage correctly in Bramic scripts. And if I change the locale in the settings, the UI of Fennec app can also properly display the scripts.

To further debug, I went to the about:config and search for fonts. Unlike western or CJK scripts, the value of font.default of Bramic scripts is serif rather than san-serif. The default value of font.name-list of these Bramic scripts are just Noto Sans or Noto Serif. I tried to switch between serif and san-serif but got no luck.

I was wondering how to fix this issue. Thanks!

for about a month my firefox home screen is greyed out in the "thought provoking stories" and it is continuously flashing. Everything works, ie. I can still search the net, etc. but this is driving me crazy. I have tried everything from checking settings, through extension conflicts and resetting, but nothing makes any difference. I even uninstalled and reinstalled Firefox but it came back with the same problem. i have windows 10 and am getting ready to upgrade to 11, but I would like everything working as it should before doing the upgrade. I even tried to change my profile, but I'm not sure how to do it and it made no difference. Any help will be much appreciated.
