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 topic chosen is the best of a 'bad' list.

I have started using the Multiple Profiles feature in Firefox.

If I have two instances of Firefox running and I open the Bookmark Manager in both instances there is no obvious indicator as to which Firefox instance a Bookmark Manager belongs.

I have currently created a folder within the Bookmarks Menu folder that has been given the same name as the profile. Is there a better way?

Сегодня 23.04.2026, я открываю браузер и вижу, что моя строка и ярлыки находятся сверху, а не в центре(1 скриншот). Вчера 22.04.2026 все было хорошо, я покажу на 2 скрине как это должно выглядеть. Хочу заметить что у меня включена функция Handoff и она мне удобна, но мне неприятно видеть блок с ярлыками и строкой не по центру. Я использую тему ffultima, скажу еще раз, вчера все было нормально. Версия фаерфаокса у меня - firefox developer edition

When I select a line of text, normally it would get deleted/overwritten when typing a new line of text, but when I select text in Firefox and begin typing again, it simply deletes the first word in the selection and keeps the rest. Is there a setting to have ALL text selected deleted/overwritten when new text is entered? Selecting one word overwrites the whole word but when an entire line to be deleted is selected, only the first word is deleted and typing begins where that word ends.

i am experiencing an issue with firefox where backup (Firefox Backup) is not working since version 148.0

problem: - when I try to create a backup, i get the error: “Hmm, there was a problem with the backup. Please try again in a few minutes.”

what I have already tried: - enabled and disabled backup password - changed the backup folder/location - cleared browser cache - tested across multiple updates (issue persists)

- backup is enabled, but I cannot create one - the error occurs every time - restarting the browser and system did not help

The question has been edited after doing further testing on the issue.

During the last week or so I have encountered the issue that one or more of my Firefox profiles keep resetting after every update.

I noticed there's couple of threads with similar issues already but the generic profile restore instructions are not helping at all since it seems that Firefox is actually wiping some files. I'm not currently sure what causes the files to be wiped, but it's either related to rebooting the PC or starting / closing Firefox. The file deletion also doesn't always hit the same profile either.

I'm running Firefox 150.0.1 for Arch on CachyOS.

I did a clean reinstall of Firefox. After the install I created 2 new accounts in addition to the one that's pre-created on install. All of the profiles work as expected at this point.

The profiles seem to have files in three places

• $HOME/.cache/mozilla/firefox
• $HOME/.config/mozilla/firefox
• /run/user/1000/psd/

The issue seems to be that after a reboot the files under /run/user/1000/psd/ are missing. Both of the other locations seemingly are unchanged but under $HOME/.config/mozilla/firefox the linked files claim no target in /run/user/1000/psd/ is found.

When looking at the missing files, it seems that in total 6 folders have been wiped at the time of testing. All of the wiped directories were ending as ".Profile 1" or ".default-release". Directories ending with ".Profile 2" or ".default" were still there. At this point I'm not sure what is causing this but it seems to explain why the profile is inaccessible.

Manually restoring the files under /psd/ seems to fix the missing profiles completely.

I saw the update that you added vpn to firefox, but I can't use it. It doesn't show up in the toolbar anywhere and there are no vpn options anywhere in settings. When I try and create a second profile THEN I get the vpn option but when I click on it it says that I can only use it with the original profile.

I’ve been experiencing an issue where dragging a URL or text from Notepad++ into Firefox causes the text to be removed from Notepad++. It behaves like Firefox is requesting a MOVE operation instead of a COPY. This only happens with Firefox, dragging the same text into Vivaldi, Chrome, Edge, etc. does not delete the text.

Here’s everything I’ve already tried:

1. Verified it’s not a Notepad++ setting Disabled “Multi‑Editing” in Notepad++ Restarted Notepad++ Confirmed the issue only happens with Firefox, not other browsers

2. Tested Firefox Safe/Troubleshoot Mode Launched Firefox in Troubleshoot Mode (no extensions, no themes, default settings) The issue still happens there, so it’s not caused by an extension or add‑on

3. Created a brand‑new Firefox profile Went to about:profiles Created a completely new, clean profile with no imported data Tested dragging again — the issue still happens even in a fresh profile

4. Reset and recreated drag‑related Firefox preferences I checked and/or reset the following in about:config: ui.dragThresholdX → recreated as Integer = 16 ui.dragThresholdY → recreated as Integer = 16 dom.event.clipboardevents.enabled → set to false browser.drag_out_of_frame_style → set to 0 browser.search.context.loadInBackground → false browser.tabs.searchclipboardfor.middleclick → false browser.urlbar.update1 → false widget.disable-native-drag → true Restarted Firefox after each change. None of these resolved the issue.

5. Tested modifier‑key behavior Holding CTRL while dragging does prevent the text from being deleted → This confirms Firefox is treating normal drags as MOVE instead of COPY.

6. Verified it’s Firefox‑only Dragging the same text from Notepad++ into Vivaldi, Chrome, Edge, Word, Notepad, etc. works normally Only Firefox causes the source text to be removed

I'm at a loss of what the issue can be or where to go from here or if there is no fix at the moment.

Hello All,

I'm using Firefox (149.0.2 snap) with LUbuntu 24.04.4 LTS. Because of a wrong graphic driver, I had to turn off hardware acceleration in FF.

When FF is started the Initial "Firefox - Choose User Profile" is unreadable (see attached : wrong_screen.jpg), but if I continue (click somewhere in the window) , all the opened tabs are readable.

Once in FF, if I want to select another profile from the application menu -> .. -> manage profiles, then the "Choose User Profile" window is fine (see attached : good_screen.jpg).

I tried to start FF with the "-P" option to specify wanted profile but it continues to start with the unreadable "Choose User Profile" window.

Could someone give me a solution, except finding the good hardware driver for my computer?

Thanks Bouilla.

I am the developer of FastF1, an open source Python package for downloading and analyzing Formula 1 race results, timing data and telemetry. The package is widely used in the fan community for independent analysis of results. For some advanced features, the addon requires users to authenticate with their Formula1/F1TV account. Since their services don't have an open login API, a companion addon is required to allow users to sign in using their browser and the official website.

I have just noticed that my developer account has been banned and the addon was blocked in Firefox. I have not received any email about this and don't know why exactly this decision was made. I'd like appeal this and reinstate my account and the addon, but I don't know how to proceed from here.

FastF1 and the companion addon are fully open source and intend no harm to users. https://github.com/theOehrly/Fast-F1 https://github.com/theOehrly/fastf1-companion

I hope this problem can be resolved.

First of all I've noticed that even logging in to the account management page doesn't work with my vpn on. So of course sync itself doesn't either. It works perfectly fine with it off though. Is there an IP address that I can add to split tunneling to allow only the sync/FF account manager through my vpn? Or another way I'm not aware of? I'd rather not have to allow the whole browser through my vpn if possible.

I really appreciate Firefox's built in translator; it is extremely helpful. However there is one thing that bugs me, when translating a page that has multiple language options. For example, when translating a page from German to English, the word "Deutsch" (often listed in the website's built in language settings) is translated not to "German", but to "English". While technically correct in that the page is now displaying English thanks to the Firefox translation, it would probably be better to show "German" so that it is easier to switch the website language and not have a duplicate "English" option in the website's dropdown menu. I have noticed this on multiple websites, specifically with German, but it might be with other languages as well. Hopefully this explanation of the issue makes sense, and see my attached screenshot which shows this issue. Please let me know if there is somewhere else I should submit this too.

I was really shocked and horrified to see Firefox place the Qatari regime's propaganda mouthpiece on my home screen. The Qatari regime is one of the worlds worst abusers of human rights. It allows no political parties, tolerates no criticism, and severely punishes online dissent. It has absolutely no LGBQ rights, is deeply misogynistic and antisemitic and uses slave labor extensively. Additionally, it is a known supporter of extremism and terrorism. It is not OK to push their propaganda outlet on the front page.

When I logged in this morning my FireFox screen had changed. The window for searches had disappeared and the "pocket" selections were all about India and its events. None of the previous options were there. What happened and how do I get back to where things were?

Either removing certain ones I don't care about or getting ones back I may have already taken out?

I don't see either of those functions any more but I swear there was a way to do it just a month ago.

I have been using Firefox with Dragon Naturally Speaking Professional 16.1 since 2022. Never had a problem with dictating into any boxes or search bars before today. Now I cannot dictate into those and I need to. I am a quadriplegic and ventilator dependent and need to use Firefox and be able to dictate into it. Can someone tell me what to do to get that to work again?
