i don't believe its memory issues because my PC has 61.6 GB of 474 GB free, and i never got these crashes before the update, with the same amount of data. dunno what else to add here, let me know if i need to provide something more

Before the last update, I’m using version 157.0 now, it was possible to simply move a complete Firefox tab using drag-and-drop. I frequently used this feature in a multi-monitor setup. While it is still possible via a right-click and the "Move Tab" option, that takes more effort than simply clicking and dragging.

Is that just switched off and hidden in some options, and really no longer possible?

Thank you,

How can I set the shortcuts on the home page to show only my favorites instead of frequently visited sites? I can't simply disable the shortcuts—it's inconvenient without them—but constantly deleting unwanted shortcuts is a hassle, too.

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.

When searching inside a webpage the color of the item found hardly distinguishable with my theme. I tried to modify the ui.textSelectBackgroundAttention parameter of config. No results. The color stays the same old one.

Reduce the width of the form and then open the top menu bar, or trigger and display the menu bar. The maximize and close buttons on the top right side will not be fully displayed. You can refer to the GIF animation below.

For the last several weeks, one of my computers when it updated to the new settings menu (version 156ish?), it has lost the ability to maintain some of the synced profile settings. For example, I have a couple websites that I list in the exceptions to not have Firefox clear the cookies, and I additionally have the clear cookies and site data check box enabled so that every other website I visit clears upon exiting. This is the setting combination I have utilized for years to keep the cookies from only 2 websites and clear out everything else.

On one of my computers, I'm able to add the exception, and as long as I do not close Firefox, the website exception settings stick. However, as soon as I exit Firefox, and open it back up, the settings clear themselves again, and I have to manually enter the exceptions again. This is very frustrating because one of the sites that I keep the cookies on the exception list has multiple different logins saved so that I don't have to manually re-login to every time I open Firefox.

I have attempted a refresh, and that did not fix the problem. I have fully uninstalled Firefox, manually deleted the %APPDATA%\Mozilla\ folder contents, reinstalled foxfire and this too does not fix the problem.

The weirdest part of this whole issue is my laptop, does not have this problem and the exceptions are sticking so I know that this setting combo works. Additionally, I have tried unchecking the clear cookies and site data box and this too is not allowing the exceptions to stick.

I have also tried re-syncing my account to pull the settings from my laptop and this too is not working.

This experience is on Firefox 157.0.1 (64-bit), Windows 11 Pro 26H2

Thanks for your time and please advise as to how to fix.

I've tried troubleshoot mode and the problem remains, I have no idea what I did and I've spent a good hour of research and found nothing to help with my problem, I'm at the end of my witts. The problem is most visible with google docs, but it goes beyond, like these huge lines in the corner of boxes like the one I'm typing in now (see screenshots).
