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:

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!

Firefox decided to not play any sound on my laptop, Spotify works on itself, if I open it in Firefox it doesn't. Same with YouTube and everything else. I use Artix Linux, I double-booted with Windows and it works on it, just not on Artix for some reason. I have tried to allow acces to it, even redownloaded everything, nothing worked. It's not the biggest problem, since there are subtitles, but it would be good if it worked.

I don't know why any browser never seems to allow for this. I hate using the mouse wheel to scroll down webpages and always use the scroll bar on the right side. Problem is most of the time it's way to skinny/narrow to be practically used and the bar you use to scroll it up and down - especially on long pages - is so tiny as to be completely unusable. It may not be an issue for tweens who still have eyes like hawks but for older people, like me, it's a pain in the tuchus. I'd like to be able to increase both the size - width mostly - of the slide rail and increase the overall size of the slide bar you use to control it.

Thanks!

I am running the latest public stable release of Firefox, 151.0.1 (aarch64), and these last few weeks I've been getting prompted to grant my location over and over every time I do a Google search. In MacOS, I've granted Firefox location permission and I've repeatedly saved me giving google permission but it doesn't stop. This is happening on my MacBook Pro and Mac Studio.

Anyone else? Any tips? It's maddening. lol

Just checking Facebook "download your information" and got this:

```

     {
       "timestamp": 1781017200,
       "label_values": [
         {
           "label": "Date",
           "value": "2026-06-09"
         },
         {
           "label": "Business or organization",
           "value": "Firefox",
           "description": "The business or organization that added you to a Custom Audience"
         }
       ]
     },

Is this actual Firefox passing my info to Meta, or some Meta scammer pretending to be Firefox?

On that date, I had Global Privacy Control turned on in Firefox.

Every time I log into MOZILLA_FIREFOX it asks to update. I have tried this before. I usually just hit that NO button...When I do click on the YES button & try to update...IT WIPES OUT EVERYTHING I HAVE STORED ON FIREFOX. EVERY SINGLE PASSWORD...SHOPPING LISTS...I'm done! I now once again have to go and recover all my information. Thing is....it updates automatically........so WTH is going on? I will start looking for aother browser...is this a scam or what?

Hello, Im using localized (Lithuanian) version of Firefox. Several updates back, Firefox started including russian and Polish in preferred languages by default. Personally i know how to remove those for myself. However, since im managing around 300 computers in a school. This starts to become an issue. In Lithuania we only have one official language. And when pages in a school start opening in foreign (russian) language this starts to be quite annoying. I would love to keep using Firefox but i need help.

Hello, I recently learned that browsers will condense spaces written in HTML down a single space. As someone who thinks putting two spaces after a period is more legible, I was wondering if there is a way to disable this, either in settings or with a browser extension. I know this will result in a less consistent browsing experience because not everyone types this way, however it will make my browsing experience better when reading things written by people who also believe in using two spaces. Thank you.

Eliminating 40% from the zoom options was a change that seems quite unnecessary and is, moreover, extremely inconvenient! The previous zoom percentage options of ...80-70-60-50-40-30 were (more logical and) *far* more useful than the current options of 80-67-50-30. If for some reason you are limited to four values in this range, then I'd much prefer choices of 75-55-45-30 percent. The two images attached are saved at (resp.) 50%, which is too large for my purposes -- namely, inclusion as in-line e-mail images -- and 30%, which is too small.

after last update stop working .if I use ctrl v it will paste in. When i try using the mouse it doesn't have paste in the block that pops up.

I can click and paste in the condition box but not the description box.

If I use edge it works. I don't want to use edge

I have also cleared cookies and cache

I'm used to check certs with right click on icon beside the address. Also for own servers in my local LAN I need this. I know there is Let's Encrypt. But sometimes it's more easy to just have a self signed cert and verify it myself. Also I want to see, who signed a cert from www.snakeoil.com/insert_your_credetials.

Please help.

I suspected I had hit a "translate" somehow, but with further inspection I think I may actually have been compromised. I'm using Firefox, but the problem follows me even if I switch to Chrome or smilar.
