After copying profile that's already synced to my old account, I'm unable to set sync that copied profile to new mozilla account. According to support page, it should sync just fine by using different mozilla account. From what I noticed, this new copy profiles feature doesn't make a new profile in about:profiles, could this be an issue?

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)

Has Firefox instituted a security setting that is interfering with commerce-related sites? Suddenly I can't log in to my credit union (gets stuck on "authentication" step), amazon.com (endless "transferring data" message during login attempt), and mutual fund sites (similar to amazon.com experience). These all are related to money/commerce. I've turned off Firefox's popup blocking and even explicitly allowed cookies for the sites. I did a Refresh to get rid of extensions that might be causing problems (even though there wasn't a problem a week ago on these sites). I've tried Firefox on a second computer for the credit union site and got the same behavior. Chrome has no problem with these logins, by the way.

I really can't add to my Summary other than it's a fairly recent issue, started in May 2026, possible April. About.config is set to False. I hope some has a solution - it happens when I'm dealing with live incidents.

Recently, a couple of web pages I've tried to accessible do not load -- I only get a blank white screen.

I've checked possible issue with a firewall, with no resolution. Also checked other security and privacy settings without finding a solution.

This is a recent happening, only happens with a few sites ... which seem to work fine on other browsers.

Any help would be greatly appreciated. jb

Enhanced Tracking Protection is preventing access to x.com even after it is allegedly "turned off" for this site. I have been using personal computers since the 1970s after the IBM PC was introduced, but now I am about ready to ditch Firefox AND Windows 11 to install a decent version of Linux. Grok on my iPhone 8 offered several suggestions to resolve this issue, but none of them have worked so far... including trying to us Microsoft Edge instead of Firefox.

I spent almost an entire day setting up my firefox browser shortcuts, themes and extensions on my laptop. It was exactly how I wanted it. Now it is all gone! I had not written all the web addresses down. how do I get them all back?

I would like you to demonstrate how I can do this through Firefox settings. I remember having these widgets activated a while back, but they went away after I reset all my settings. I've spent tens of minutes looking through all Firefox settings and tab customization to no avail. It is important to note that I am in the US using Firefox on a Windows 11 device.

Since updating to 151.0.1 0 on MAC OS Tahoe 26.5 , every 6 digit TOTP entered posts error - "Use another authentication method"

I use same authenticator app on Safari - no issues.

I am trying to disable the text segmentation behavior in latest Firefox(v151), but I have encountered an issue where changing the preference in [about:config] does not seem to have any effect.

Details:

   Target Preference:  intl.icu4x.segmenter.enabled
   Current Setting:       false

   Problem: 
   Even after setting this to false (and restarting the browser), the text segmentation behavior (such as word selection logic) remains unchanged and appears to still be using the ICU4X engine.

   Reference:
   https://support.mozilla.org/en-US/questions/1440483#answer-1638092

I would like to know:

  1.  Has this preference been deprecated or hardcoded to true in recent versions of Firefox?

   2. Is there any other way to disable the ICU4X-based segmenter or revert to the previous segmentation logic?

   3. If this is a known change, is there an alternative preference to adjust how word selection handles specific languages (e.g., Japanese)?

I am using the latest version of Firefox. Any insights or workarounds would be greatly appreciated. Thank you in advance for your help!
