As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

I sent message below to Bluesky support and have tried all their suggestions (all relating to Firefox), but to no avail.

MacBook Pro OS 10.14.6. Yesterday (9Dec2025) I could open Bluesky & see my profile but could not add a new post. I then did an ‘age verification’ and received confirming emails. When pressing ‘New Post’ button just went to blank page. Under ‘notifications’ at the top, was a message “''''! r.countGraphemes is not a function''''”. I am accessing using ‘Firefox 115.31.0esr (64-bit)’. I have deleted caches, re-started ‘Firefox’ and re-signed into Bluesky, but problem persists.

Could you please advise how I can overcome this problem. Thank you, best regards.

I've been using Firefox all morning. Now, for some unknown reason, every time I start it up, it immediately crashes Windows. I mean, within 1 second or so. There's no time to do anything. After the fourth crash in a row, I just restarted Windows again. It was humming along happily for 10 minutes or so, and then crashed as soon as I started Firefox. After the first crash, the first thing it did was update, but that didn't fix anything. I'd love to share data with you but I'm forced to use Edge right now.

"Move Focus To Next Window" keyboard shortcut behavior on OSX Tahoe (26.1)

Recently, I've found that the OSX keyboard shortcut for focusing the next window in the current application ("Move Focus To Next Window" in System Settings) has changed its behavior. Pressing [cmd + `] will only cycle Firefox's windows until it reaches what seems to be the "end" of the current list of windows open. After this, I have to press [SHIFT+ cmd + `] to go backwards through the list of windows to re-focus any of the other windows.

Before, the behavior was such that I could just repeatedly press [cmd + `] and Firefox would infinitely cycle through all open windows, no shift key needed.

I haven't been able to reproduce this changed behavior in any other applications. Testing this in others (Finder, Safari, etc.) yields the cycling behavior instead of making me reverse the direction with shift to get back to the previous windows.

This is tied to the operating system's command. If I remap the keystroke to something else in system settings, I still need to use the shift key with it in Firefox once I reach the last open window.

Is there a way to get the old cycling behavior back? I find the key command with the shift key to be much less ergonomic.

So I reformatted my hard drive and everytime I finish I reinstall Firefox. I have an account where I log in and it put me back where I left off with all my past bookmarks that I saved. Ive been doing this for 10 years but today not sure whats going on but when I logged if all my stuff has disappeared. Please help or contact Mozilla regarding this. I cant understand why one cant directly speak to the ones who developed this browser. Quite frustrating

Hi there, My laptop undertook an update for Firefox and I have just discovered that all of my bookmarks have disappeared and I cannot find anyway to restore these. My laptop cannot access any profile, I have followed advice in other posts, but I cannot find access to this data. I have lost all my Masters Degree bookmarks and my BSc, which I need access to asap to continue. Can you please advise on how I can get these back?

I have checked my mobile Firefox and it still has access to these bookmarks but there is no way for me to export these files out of my mobile. I am worried about undertaking a sync (although it says it has) in case it deletes all of these bookmarks.

Your help is greatly appreciated.
