Firefox Community Forum

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!

I'm blaming the latest Firefox update from a couple of days ago, since this problem only arose yesterday. Now cut off from reading and following news that I really want to receive.

This is what I get when trying to access links within a few of the websites that I regularly access for links to articles it posts:

The site ahead may contain harmful programs

Firefox blocked this page because it might try to trick you into installing programs that harm your browsing experience (for example, by changing your homepage or showing extra ads on sites you visit).

Firefox v153 downloaded a day or 2 ago. Since when it freezes, cannot access internet, then crashes regularly. have to restart to get it working again. PC with windows 10. Despite windows settings showing internet connected, and other device connection fine. I've stopped the VPN plugin. Have submitted 3 crash reports just now bp-03b76eff-3e9d-4778-a790-7913d0260725 bp-f4ffd17f-b408-4b1a-a1ea-391190260725 bp-123c3ae2-1d94-4abb-a040-875720260725

It was freezing every few days before the update, but now it's 2-3 times a day.

Using version 153 on Windows 11. I have never been able to activate the VPN. I have tried ALL of the suggestions on the support site, permissions, policies, customize toolbar, etc. There has never been any icon to activate. Obviously, this has been going on for months. Thanks.

Hello everyone,

I've recently noticed that Firefox has become slower than usual. Some websites take a long time to load, and occasionally the browser feels unresponsive even though my internet connection seems to be working fine. I've already tried restarting Firefox and clearing the cache, but the issue still occurs.

Has anyone experienced something similar or found a solution that improved Firefox's performance? Any suggestions would be appreciated.

Thank you!

I have been using the browser extension feedbro and i really enjoyed being able to plop it out of the main browser window and 'add it to the taskbar' but for a couple days this option disappeared. Is there another way to do this? did "add tab to taskbar" get removed for browser extensions? or is this feedbro related? i am unsure how to test whether the button is missing for other browser extensions as well.

added two images showing that the button is gone from feedbro and still there for other tabs/pages

This started since Firefox 153.0 (Debian package).

When I open Firefox for the first time after a reboot, it opens my latest tab but all the other tabs on that window are lost, and they show as "ghost tabs" as seen in attached image.

No other issue, other windows are preserved properly when I Ctrl + Shift + N
