Firefox Community Forum

Content Security policy blocks essential scripts no matter what I do.

It's new Firefox installation, Troubleshoot mode, Enhanced tracking disabled, I'm not on VPN, can log into X.com in another browser just fine.

It's the reason #1 I don't use Firefox. I thought the issue would be fixed but it has been like this for long time.

Yet whatever I do, whatever I turn off this pops up:

Content-Security-Policy: The page’s settings blocked the loading of a resource (default-src) at https://abs.twimg.com/responsive-web/client-web/bundle.Conversation.721fc4aa.js because it violates the following directive: “default-src 'self'”

The screenshot is from Zen, but it uses Firefox and the issue is the same in Firefox.

The Firefox VPN is installed and on...it had been working great...but now, it's on, but not using any data...the data status bar stays at 50%....like it's not running...what's going on with it? Thanks!

recent firefox update can no longer copy and paste when creating a blog post in Squarespace, I have been using squarespace for around 15 years for my websites and I have never seen this issue, Firefox 15.1 installed and all of a sudden when trying to create a blog post in Squarespace, when I right click a text box pop up and it no longer says paste so I can no longer copy and paste text - this is more than a little annoying, you will not be surprised to know that I am now using Chrome to create my posts, there is no issue in chrome. I am a firefox geek! how can i solve this problem, I just did another update from Firefox, the issue remains I have been using computers for 40 year so I am not a novice but software glitches, I am lost

Its REALLY annoying that I have to manually go to my downloads every time I download a pdf to move it to the correct folder. Especially when I already have Firefox set to "always ask" when downloading a file. I don't need EVERY thing I download to go to a specific folder. I sort things as I download them. Its just REALLY annoying that Google does this ONE thing so much better and Firefox used to allow me to save things wherever I wanted them every time I downloaded. Super freaking annoying.

With Duckduckgo set as search engine, if I type a search or go directly to duckduckgo search page the current tab crashes and the "Tab crash reporter" is displayed.

Google, Bing, etc work.

I have Duckduck privacy protections, privacy badger, and ublock origin all disabled for duckduckgo.

Hello, Im using localized (Lithuanian) version of Firefox. Several updates back, Firefox started including russian and Polish in preferred languages by default. Personally i know how to remove those for myself. However, since im managing around 300 computers in a school. This starts to become an issue. In Lithuania we only have one official language. And when pages in a school start opening in foreign (russian) language this starts to be quite annoying. I would love to keep using Firefox but i need help.

I am still waiting for you to remove Show All in config:editor. It was unnecessary and unwanted by your users. Just allow us to access config:editor the way we used to before this moronic change.

When attempting to load additional screen connected to my bank it does not work as intended. We trouble shot: we disabled Auto fill and PopUps. What other steps should I take?

I noticed that the World Clock widget includes Pakistan Standard Time (PKT) but does not provide an option for Indian Standard Time (IST). This is surprising given that India has one of the world's largest internet user bases and a significantly larger population than many countries currently represented.

India operates on a unique UTC+5:30 time zone used by over 1.4 billion people, making it one of the most widely used time zones globally. The absence of IST while neighbouring time zones are available feels like a major oversight and reduces the usefulness of the widget for Indian users and anyone who regularly works with Indian colleagues, clients, friends, or family.

Please add Indian Standard Time (IST) to the World Clock widget as a standard option. Its inclusion would greatly improve the widgets global coverage and usability.

I am trying to configure our Firefox configuration via Intune and need to use the OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox/Preferences with the following JSON:

<enabled/> <data id="JSON" value=' {

 "dom.disable_window_flip": {
       "Value": true,
       "Status": "locked"
     },
   "dom.disable_window_move_resize": {
       "Value": true,
       "Status": "locked"
     },
"network.http.http3.enable": {
       "Value": false,
       "Status": "locked"
 }

}'/>

I do not have any of the Deprecated preference settings in use.

The error presented is -2016281112 and checking the respective settings in about:config on a synchronised device shows that the settings have not applied.

Any help would be appreciated.

Thanks!

Hello, I bank with Fifth Third a regional bank in Ohio. I travel a lot.illa not have a While on a trip I was unable to connect to my bank. One of the issues they mentioned is Firefox is not secure and thus will not interface with their system. My question is why does Mozilla not have a team which inter-acts with banks to insure that Firefox works properly and is considered safe, secure, and reliable? Thank you, Bill
