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!

Firefox stops loading websites after Mac lock/unlock I am using a MacBook with Apple M1 and Firefox 151.0.2 (aarch64). Whenever I lock my MacBook and unlock it later, or leave it idle for a longer period and then log back in, Firefox stops working properly. It appears to stop resolving DNS requests. Every website remains stuck with messages such as **"Waiting for http://..."**, and no pages load. This issue affects all websites. At the same time, Chrome works without any problem and is able to load the same websites successfully, which suggests that the network connection is working correctly. The only workaround is to force quit Firefox and start it again. After restarting, everything works normally until the next lock/unlock cycle. This issue occurs consistently after the Mac is locked or left idle for an extended period. It is significantly impacting my productivity and reduces the reliability of using Firefox as my primary browser.

Please suggest the way to fix this.

Firefox used to display an AI overview response at the top of the page when you asked a question. That feature has disappeared on my systems. I assume that is because of the new AI controls. Is that function still available? If so, how do I re-enable it on Windows 10? The only video I could find addressed it for Windows 11 but I'm not there yet.

Using the Firefox 151.0 Mozilla Firefox for Fedora. Updated as of 23 May 2026, I use just a generic FireFox. I don't customize it, I just use it as it comes from the Fedora distribution.

I cannot save images (right click menu "Save Image As"). Nothing happens when that is selected. This worked a couple weeks ago.

Downloads are supposed to go to ~/Downloads. Checking the setting for this, Go to the three-line menu > Settings > General > Files and Applications, under Downloads, the "Save files to" value is set to Downloads, but the Browse button does not work to reset it. Nothing happens when I poke on the button. I can select the text in the box, but I can't change it.

I found the help page for "What to do if you can't download or save files https://support.mozilla.org/en-US/kb/cant-download-or-save-files and went thru every one of the steps there. None of them make any difference.

Strangely enough, there isn't even a "Downloads button" in the top toolbar. If I right click on the top toolbar and select "Customize Toolbar" it shows a downloads icon as already being in the toolbar, but when I click Done, it goes away.

I am suddenly getting ads across websites in Spanish, and my Amazon account flipped to Spanish. I used several IP geolocation services which identified my IP address is assigned to Mozilla Corporation in Queretaro, Mexico, despite my Mozilla VPN being designated United States. How do I solve this problem?

Hello Mozilla Team,

I'll directly jump into - 12 years of Bookmarks and history are gone after the last update. No warning or anything. Can you help me restore? That's unbelievable.

I have selected the 4 rows for shortcuts on my tab and have installed all but the last 3 spaces in the end of the 4th row. There's no option whatsoever to continue to add those remaining 3 spaces. Any suggestions?

Please create a new version of the browser app that supports the ability to use FileSystemAPI on directories, this is essential for working with a BeatBuddy project and SD cards that are saved on my computer using the online editor. Many thx, Manfred

How do I stop this page from coming up several times a day. I have already set FireFox as my default browser, several times, but to no avail. I've careful followed your instructions. I dislike MS and have used FF for years. If this doesn't stop, I'll search for another browser that hopefully behave. I have set it on 4 computers, 2 Win 10, 2 Win 11.

By the way, the computers show FireFox twice, but only one actual installation.

Please do better!
