recent firefox update can no longer copy and paste when creating a blog post in Squarespace, I have been using squarespace for around 15 years for my websites and I have never seen this issue, Firefox 15.1 installed and all of a sudden when trying to create a blog post in Squarespace, when I right click a text box pop up and it no longer says paste so I can no longer copy and paste text - this is more than a little annoying, you will not be surprised to know that I am now using Chrome to create my posts, there is no issue in chrome. I am a firefox geek! how can i solve this problem, I just did another update from Firefox, the issue remains I have been using computers for 40 year so I am not a novice but software glitches, I am lost

Yesterday Firefox started crashing tabs on load of a handful of websites that are seemingly random, like Twitter and a few shopping site tabs I had open. It wasn't after a system update or anything, it just started happening while Firefox was already open and those tabs had already been open and loaded. I've tried clearing my cache, site data, reinstalling Firefox, and it still does it. Upon further investigation, it seems to be something regarding libfontconfig, and mostly specific to users of openSUSE Tumbleweed.

On Windows 10 Home I've been using Yahoo Finance to track stocks. After updating FF last week I have not been able to load graphs. I've tried refresh, reload, restart, remove cache but any graph shows "loading" or is blank content. Every idea except delete FF and reinstall. Other browsers I sometimes use do load the graphs no problem. What else can I try, or is this a bug? Thanks

I have been using Firefox forever. It has been running very slow and bugging out especially with you tube on close. I've been working on this for a couple of weeks and am about to give up. My self built system is about 10 months old. Am using a completely debloated MS 11 pro 25h2. Did not ask for AI from Firefox and have disabled AI in Firefox and copilot is long gone. I have tried everything. Am about to quit firefox. Have refreshed firefox and prevented firefox from running in MS win 11 pro "efficiency mode". I usually have to exit firefox with task manager - there are usually 17 instances of firefox running. Mozilla has become Microsoft.

The system: Gigabyte B650 mobo, 32 gig of DDR5 6000, AMD 7700X processor and an Asrock 9060 graphics card with 16 gig DDR6 Vram. All other apps are running just fine. So I don't think a lack of compute is the problem.

Help please! Thanks in advance!

Every time I open Firefox, the checkbox next to "Opening links in tabs" always disappears, even though I've checked it in previous sessions. How can I make it permanent?

I use Firefox on the Linux Mint operating system.

Is anyone looking into this? I found an article that told me to remove some cash files and it seemed to fix the issue but it continues to reoccur. Some apps such as MS360 Outlook seem to trigger it, but if it was truly just a corrupt cache issue then cleaning the cash/profile once should have fixed the issue. Instead its become a constant pain in the *** and I'm tempted to find another browser. Seems very recent as well as I've never had issues with firefox before.

Ubuntu 24 Mozilla Firefox 151.0.3

I am still waiting for you to remove Show All in config:editor. It was unnecessary and unwanted by your users. Just allow us to access config:editor the way we used to before this moronic change.

I am trying to configure our Firefox configuration via Intune and need to use the OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox/Preferences with the following JSON:

<enabled/> <data id="JSON" value=' {

 "dom.disable_window_flip": {
       "Value": true,
       "Status": "locked"
     },
   "dom.disable_window_move_resize": {
       "Value": true,
       "Status": "locked"
     },
"network.http.http3.enable": {
       "Value": false,
       "Status": "locked"
 }

}'/>

I do not have any of the Deprecated preference settings in use.

The error presented is -2016281112 and checking the respective settings in about:config on a synchronised device shows that the settings have not applied.

Any help would be appreciated.

Thanks!

I signed in to https://accounts.firefox.com to sync Firefox on iPhone iOS 26 and got a sign in from an unexpected location.

Firefox iOS on iOS 18.7 Toronto, ON, Canada (estimated) Tuesday, Jun 9, 2026 11:43:14 AM (EDT)

I am in the NY,US and do not own any iOS 18.7 device.

Can you give me more information why the jump to a foreign device?

I play https://crazyshooters.com/ and https://crazyshooters2.com/ a lot! But the game became laggy since Firefox 148 and my ping spikes up. Other browsers play fine. I am on Linux Mint if that helps. (147 and below run fine)

After I key in all my passwords they disappear after a while. sometimes they last a week of two,and other times just a few days. One time it happened when fire fox did a update . Any help would be appreciated.

Updated to FF 150 today on Win 11 desktop.

Q1: Can I remove Profiles from the FF toolbar which is located in between Bookmarks and Tools? Only need one profile on this PC. I tried to customize the toolbar but it won't let me drag Profiles off.

Q2: For some reason my FF profile is now on C: even though I had previously moved it to D: to free up space on C: boot drive.

So I created a new profile with exact same folder name on my D: drive today.

In Profile Manager, I renamed the old profile on C: to "name.old and the new one on D: to "name.new". I set name.new as the default profile and it works properly after exiting and restarting FF.

Now I want to delete the .old profile but FF won't left me, saying Can’t delete a profile that is linked to other profiles. There are only the .old and .new profiles listed. So how do I unlink .old so I can delete all of it to free up space on C: ?
