The full error message is: "The procedure entry point ?WindowsBCryptinitialization@mozilla@@YA_NXZ could not be located in the dynamic link library C:\Program Files\Mozilla Firefox\xul.dll."

After accepting that, I get another message that says: "Couldn't load XPCOM." Then, it just quits, with no Crash Reporter dialog.

I downloaded a fresh installer, but it takes a couple minutes to even launch, and then just sits there for a long time on the initial screen doing nothing before saying the installation failed. I've restarted my computer twice hoping it was a one-off issue, but there's no change.

According to the file information, xul.dll was last changed September 3rd, so it may not be the source of the issue. Perhaps whatever name mangling is responsible for the above entry point changed and now they don't match?

I have automatic updates set to "download but don't install", so it downloaded it a few days ago and I just restarted it this evening and the issue occurred. I could understand that maybe something got corrupted during the update, but I have no idea how the installer could also be failing.

I recently updated my Firefox to v158 from v156, and now the text colors of some of the UI elements on a new tab (e.g. Firefox wordmark, web shortcuts, Recent Activity header) which were previously white, have been changed to black (or a color close to black).

I use a custom wallpaper for new tabs, which didn't alter these particular colors on v156. Switching the background in the Customize menu shows the white text on some of the default wallpapers and the dark text on others. I have attached example screenshots to show how these elements looked before and after the update. I used the Developer Tools console to do this.

I assume this has to do with the "modernized" Nova UI redesign (which I have disabled) Mozilla is now forcing on its userbase instead of making it optional. Reverting these properties via the Developer Tools console does not make them permanent. I would rather not have to change my current wallpaper if I can help it.

Is there any other way I can make the text white again without changing the background or downgrading? Or if I can make them permanent with the console?

Dear Mozilla Team,

As a loyal and long-time user of Firefox and Mozilla products, I am writing to you today with a heartfelt appeal regarding a critical issue facing internet users in Turkey.

While I am glad to see that built-in VPN features have been successfully rolled out in various countries worldwide, it is deeply concerning that this feature is notably unavailable in Turkey. In recent years, Turkey has experienced severe restrictions on freedom of expression, heavy censorship, and increasing limitations on human rights.

In this challenging environment, people—especially the youth and those striving to keep up with global knowledge, science, and civilization—rely heavily on an open and unhindered internet to maintain their connection with the wider world. Unfortunately, authoritarian administrations actively seek to silence these voices and isolate societies.

As a steadfast champion of privacy, security, and an open internet, Mozilla has always stood on the side of users. Turkish users are in dire need of built-in VPN support to bypass these heavy restrictions and reclaim their fundamental digital rights.

I sincerely hope that Mozilla will hear our voices, recognize our urgent need, and take steps to make the built-in VPN available in Turkey as well. Thank you for your dedication to a free and open web for everyone.

Best regards,

Brusky A long-time Firefox user from Turkey

With the new FF 157.0.1 (64-bit) it seems the download icon in the toolbar is now purple. I want this back to the old colour but have no idea how to do this. Why was this changed, because the colour hurts my eyes.

BTW .. using FF on Windows 11 (25H2)

Thanks, Matthijs

As soon as I signed into the browser to sync my account, this issue began. I have deleted profile locks, started new profiles, opened in troubleshooting mode, fully reinstalled, and the issue continued (even before signing back in). I am out of troubleshooting steps and would like to avoid blowing my VM away if at all possible. Someone please help!

Ok this latest UI appearance change is absolute dog feces. I hate it so much! It's so ugly! How do I change it back? I did not consent for my eyeballs to be assaulted like this. Did I mention it sucks? How do I change it back? 157.0.0.11

So I'm helping sort out an individual who is very computer illiterate and I'm getting them to use Firefox.. but when it updates, the window that tells you what's new pops up... now this is helpful for most! but for this individual it really confuses them and they tend to call me about it every time... so I'm wondering if their is a way to disable the popup window, to make it less confusing for them without disabling the updates entirely?

Desktop version update to 157.0.1 acted like a fresh install. Prompted me to import from previous browser. Firefox was my previous browser. I have my bookmarks backed up, but lost all my tab groups, which is a huge problem to try and recreate. Lost downloaded themes. Lost downloaded extensions. Why did this happen? I can't imagine it was by design.

I know that I can change the appearance of Firefox with themes. I am currently using a light-colored theme called Elemental - Soft. Even still, whenever I go to print something or look at my history the backgrounds are black, which makes them hard to see properly. I have tried using the default theme in Firefox but this problem still exists. I'm using no other extensions or plug-ins to make my browser do this.

Second, is there any way to get rid of the purple highlights around boxes such as the ones in the print dialog screen? I really dislike this color.

Thanks

Why is about:home is completely blank? Updating to Firefox 153.03Beta made it all disappear. Must I reinstall Windows-XI for this user-interface not loading anything that has been updated on Firefox 155.03Beta? I will attempt an optimization and see if that does anything. If it does, I will close this; but if not, it is quite some new bug.

I have done everything I can find to get my Firefox bookmarks menu working correctly in Windows 11. Every time I shut down and come back they are not working and I have to do a restore. The bookmarks are there but they are dead, inactive. I can do a restore and everything is happy, until I shut down and log back in.

I've done 2 clean new installs including deleting all the folders and files.

I've also done deleted remaining Program & Profile Folders (For a True Clean Install)

Ich wollte die Beihilfestelle beim Landesamt für Finanzen aufrufen. Das ist leider nicht möglich. Könnte es sein, dass es einen Zusammenhang gibt damit , dass ich vor ein paar Tagen ein Antivirusprogramm von Avast heruntergeladen habe, nachdem ich seit Monaten dazu von Avast genötigt wurde, da mein Laptop angeblich schwere Probleme aufweisen würde. Beim Online-Banking hatte ich vor Wochen ein ähnliches Problem (das war allerdings noch vor dem Herunterladen dieses Antivirusprogramms), dass meine Zahlungen nicht verifiziert werden konnten. Nach Kontaktaufnahme mit dem Service der Bank sagte man mir, dass ich einen anderen Browser benutzen solle, da Firefox angeblich Sicherheitslücken aufweisen würde.

Regarding FF v157:

- Mozilla have changed the Graphical user interface of Firefox without asking for consent or providing a clear way to revert back to the old interface, yet again. - They have made changes to the settings, so pre-installed search engines can only be toggled off and NOT removed... - There are a bunch of themes now pre-installed that can't be removed.

I think pushing a change without over way to revert, is why I a lot of people don't donate to the Mozilla foundation

Hi,

Firefox 140.17.0esr (32-bit), Windows 11 23H2, trying to open https://babia.to but get a blank screen. By F12 I see this error in the console:

None of the “sha512” hashes in the integrity attribute match the content of the subresource at “https://static.cloudflareinsights.com/beacon.min.js/v4bc70e2c01a94c73b74392e4234840661791215815920”.

If I open it in Chrome 140 it opens fine. What's the issue with my FF and how to have it fixed?
