Would like to test nightly builds of Firefox - how best to get started?

I am a user of Ubuntu and interested in testing the Firefox Nightly via snapstore.

Any pointers helpful.

I'm building a website from scratch and its going great. I just tried to implement a CSP and it worked except for one small section of my website that allows a user to upload an image and that image is supposed to be displayed back to the user. Anyways long story short the CSP blocked me so I tried to whitelist data: and it still didn't work. defeated I removed the CSP from Nginx to work on it later but when I went to try and test again I get this error. ``` Content-Security-Policy: The page’s settings blocked the loading of a resource (img-src) at data:image/webp;base64,UklGRqbeAABXRUJQV… because it violates the following directive: “default-src 'self'” ``` I have confirmed with Curl and by inspecting the network tab that there is no CSP included in the headers anymore. I have restarted Firefox, created a new Firefox profile, and cleared my cache to the end of time and yet still the error persists. I don't know where or how Firefox is storing website headers but they persists and also apparently work between profiles an implication I'm not going to delve into here. If someone could point me to the file where the headers are stored so I can delete it that would be wonderful.

I wanted to set keywords for search engines (in order to quickly change them for a single query). This cannot be done for search engines by default (why?), so I had to delete them and create a new one with the same link and my own keywords. But now I can't give them the same name back, firefox says that such a search engine already exists. In general, it doesn't matter to me which letter is there. The main purpose of my appeal is to draw attention to the fact that search engines cannot be edited by default, because it is quite inconvenient. Thanks for the answer (I apologize in advance if I made a grammatical mistake somewhere, I used a translator) My OS: Ubuntu 24.04 LTS; firefox version: 145.0.2 (64-bit)

Since the redesign a lot of thing don't work anymore.

In the menu at the right side with the dots important items e.g. bookmarks are not contained any more . How do I manage my bookmarks with the new Design? Is it possible to return to the old menu? Is there a manual explaining the new menu? The German help page online explains how it used to work.

I first noticed that things don't work anymore when I tried to download my subscribed newspaper in the app for this particular newspaper. Regards, Ute

Ubuntu 24.04.3 LTS new installation. Thunderbird 140.3.1esr (64-bit) Adding an existing account Type in My name and email address and click Continue It says it is looking up configuration and it is just looping around and does not report an error. I have waited over an hour with no result. The only way to recover is to go to the taskbar and right click Quit. It would be helpful if there were away to know what is blocking the search for the configuration.

Just like the Android version of Firefox does! It opens the new tab(s), but load each tab at visit!

Desktop Firefox also does this at [History / Restore Previous Session]. All the previously opened tabs are opened again, but each of them only loads at visit.

This is I would like to have as default behaviour with newly opened tab(s) in Firefox. > Tab opens. > It hasn't loaded yet! > At visit it loads the content.

PS: I tried, but didn't work: > about:config _ browser.sessionstore.restore*demand (switch) > Addon _ LoadTabOnSelect 3 (But it worked weirdly.)

Hello !

I am trying out a Linux (Fedora 39) with enhanced privacy (hardened firefox with the user.js from Arkenfox). My problem is the following : When I quit a video that was in full screen with Esc. the inner window dedicated to the webpage resizes to a smaller one such as the one seen in the screenshot.

I fixed that by going into troubleshoot mode and the window went back to its original size and then reactivated my extensions but the same problem appeared when following the process aforementioned.

Any idea what could be causing this ?

Best regards,

One of the websites I need for school requires pop-ups. I can't click on the button to permit pop-up windows for just that site because it only flashes for less than a second and it is grayed out. I tried to go to preferences to disable the pop-up blocker, but the checkbox to disable it is grayed out. I created a new profile, but the button to disable the pop-up blocker is grayed out on that too. I now have to use chrome for this website because I can allow pop-ups on that browser.

My question is why is this setting grayed out? And how can I re-enable pop-ups or at least edit the exception list because that is grayed out right now too. Any other tips for troubleshooting similar issues in the future would also be appreciated.

OS/Firefox packer: Artix Linux Firefox ver.: 142.0 (64-bit) Tested on brand new profile

On Firefox 124.0.2 (on Ubuntu 22.04.4 LTS), when I click a download link on a web page, Firefox doesn't download the file. I tried disabling all add-ons, but that did nothing. However, I found that when I deselect "Ask you where to save the files" in the browser's Settings and then click the link, it downloads the file to my Downloads folder. Can someone please point me in the right direction to find a solution for this?

Hi,

On some websites (e.g. archlinux.org) most numbers are not rendered. See attached screenshots showing the same page on Firefox and on Konqueror.

In my font settings, I do allow pages to change fonts. Some pages (e.g. this one) do change the fonts and appear well. However, if I disable the feature, then they also break.

I'm using: firefox 145.0.2 (64-bit) archlinux plasma-desktop 6.5.3 wayland 1.24.0

Any idea?

It has happened now for quite a long while and quite some times that the bookmarks, with the exception of the "Import Bookmarks", disappear from Bookmarks Toolbar.

There was a time when I succeeded in solving the problem by removing the <places.sqlite> file, but or the last 2 instances it did not work.

In the first of these two later instances I resorted finally to reinstalling Firefox after the deletion of <places.sqlite>, <places.sqlite-wal> and <places.sqlite_shm> - I am not sure about the spelling of this last two - without success.

Today, running 144.0 64-bit for artlinux 1.0, that did not work.

I did <pacman -R firefox>, in order to remove it and then <pacman -Su firefox>, to install it but that did not work and to my surprise, my bookmarks appeared on the Library so I removed and installed one more time, making sure to delete the <.mozilla> before installing again.

I just reporting in case it may be helpful to someone.

When I opened Firefox[^1] today I was greeted with a "Donate to Mozilla Foundation" page open, with the message:

"You power Firefox. Now donate to make good tech the default.

Mozilla Foundation — the non-profit behind Firefox — is building a future where technology serves people, not power.

Your donation to Mozilla Foundation keeps the internet open, private, and built for people. Donate today to make good on the promise of the internet."

Does this message mean that Donations to the Mozilla Foundation now fund Firefox development? As I understand it, previously donations were not allowed to be used by the Mozilla Corporation, which actually develops Firefox. I'd love to donate to fund Firefox development, as I feel it is a critically important open source project.

[^1]: 145.0.2 from the Mozilla Debian repository.

For example, the word thema, is exclusively capitalized in German, and it shows as error indeed when lowercase, but the capitalized one is not offered in the options. Why is that and how to fix it?

Also, is there a way to autocorrect capitalization for example?

Hello,

After upgrading my Thunderbird install to version 60.2.1 on my Xubuntu 18.04 machine, I cannot access my mail anymore, because there seems to be a problem with passwords.

Symptoms:

- When starting Thunderbird, I get an "Enter your password" box for each of my accounts even though I had my passwords saved.

- When I go to Preferences -> Security -> Passwords -> Saved Passwords, the list is empty.

- When I try to enter a password and save it, it does not actually get saved and Thunderbird will ask again soon after.

- The following line is logged to console a whole bunch of times:

JavaScript error: jar:file:///usr/lib/thunderbird/omni.ja!/components/crypto-SDR.js, line 179: NS_ERROR_FAILURE: Couldn't decrypt string

Other findings:

- Downgrading Thunderbird to 52.7.0 fixes the problem. The old saved passwords just reappear again and Thunderbird has no problem logging in.

- Starting Thunderbird 60.2.1 on a Windows 10 box with exactly the same profile folder works fine. It can read the passwords and access my mail accounts.

Can you please tell me what to do to fix this, so I don't need to keep using an old version of Thunderbird just to access my mail?

Thanks,

Hello, I have a problem: After an automatic update of the language packs, parts of the Firefox menu (version 126.0) are displayed in EN. Parts in DE. Seems to be related to the update... how can I change this again? I have already changed the language settings. Didn't help...it appeared after an automatic update on May 28. Thanks for an idea :)

I want to visit http://bispebjerghospital.dk/ . I have seen on https://www.whatsmydns.net/#A/www.bispebjerghospital.dk that it's DNS isn't propagating correctly, so I turned on "MAX PROTECTION" for DNS, hoping that it would let me see the site.

But Firefox showed me "Unexpected error" the first time I went to the site. And then I clicked 'always allow' and now it just spins and spins with no response visible.

How can I visit the website from one of the countries with red X's on whatsmydns?
