The operating system is Windows 11, and the following content is configured in the HOSTS file on the C drive: 192.168.10.10 www.simon.com 192.168.20.10 www.simon.com There are two private network servers providing website services, with server A's IP at 192.168.10.10 and server B's IP at 192.168.20.10. Then use Firefox to browse the website www.simon.com and set up Firefox's network.dnsCacheEntries、network.dnsCacheExpiration、network.dnsCacheExpirationGracePeriod Three configuration items are 0. When accessing normally, www.simon.com points to 192.168.10.10. When the 192.168.10.10 server fails, will it redirect to 192.168.20.10. What is the latency for switching domain names in Firefox? What is the mechanism for switching?

We are experiencing an ongoing issue with Firefox that persists even after performing the following troubleshooting steps: - Uninstalled Firefox completely. - Removed all browser add-ons and extensions. - Reinstalled the latest version of Firefox. Despite these steps, the issue still occurs: Browser crashes, pages not loading, extension not working. Additional Information: - Operating System: Windows 11 Pro - Firefox Version: 145.0.1 - Error Message:

We would appreciate guidance on resolving this problem, as standard troubleshooting has not resolved it.

Thank you in advance for your assistance. Kind regards, Edward

Using latest Firefox browser, when I open Google and want to ‘paste’ a word, it will not let me. Instead I get this default message, that I can’t delete. I can type anything I want, but I can’t ‘paste’ a word or words. How to fix please? HP desktop PC Windows 11 64 bit I see there is a 'new' (to me) AI mode icon in the 'same' search window as where you type on the 'right' of the search box. Maybe I just haven't noticed because I didn't have an issue before.

Thanks in advance for any suggestions

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

Recently the shortcuts on the Firefox browser started being greyed out and not accessible. Using iOS ver 18.7.2. Tried lots of different things to chess them but no luck so far. A major impediment to usability

Thanks

When I use Gemini 3 visual layout function to generate a homepage-like page, but Firefox cannot show any content of the result. It works fine in Microsoft Edge and Google Chrome.

My bookmark features has stopped working. When I click the star, it does not turn blue and I cannot bookmark anything. Is there a fix? I have stuff in the bookmark area and would not like to loose it.

How do I set up Firefox to remember my login security approval for websites (for instance JPMorgan Chase Bank). Chase Bank used to remember, but now I have to verify my identity each time I log in to Chase Bank.

All of my bookmarks have been erased. It says the file is being used by another application. I have looked at the help section but the options they give does work.

I am running macos 15.7.2.

Bought a faster external drive *named EXT3* and I copied my Firefox Profiles from EXT2 *previous External* to EXT3

I have added the location for the profile in /Users/username/Library/Application Support/Firefox/profiles.ini

So far so good, but when EXT2 is NOT mounted the profile won't start, but only when EXT2 is MOUNTED then the profile will start.

Also connectivity is broken then, with that I mean I can't open any sites, not even a local one.

When I look in About:profiles I see that the profile in EXT3 is active and in use.

Any idea what is going on?

Ps:

macos: 15.7.2 Firefox Version:140.5.0 ESR

My computer glitched today. Before that I could bring up Firefox and all pages would restore.

Now Firefox comes up and shows one page like a new page. One tab and no other pages appear I had several open when the incident occurred.

Now I get the one page. From the Task Manager window I see the one page and "crashhelper" followed by several Firefox icons (all appearing to be using memory) but none of them are displaying any pages on my display.

I made a screen shot and enclosed below

My question is about lack of functionality (Topic) but it is not listed in the selections above!

I selected Accessibility because I cannot access any of the tasks shown below the "crashhelper" because none of these pages are displyed

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan

I've followed the directions I've found in looking for answers to this, and they haven't worked. My bookmarks haven't appeared when I switched between 2 profiles and nothing has appeared when I went to the Library and tried the various restoration options. I also can't bookmark any webpages since I've lost my bookmarks. I'm using this in Windows 11. Ccleaner found 19 GB of system files that it didn't name, and it wouldn't delete them, so the bookmarks may still be there - I just don't know how to find them. Thanks for your help.

I am currently using Windows 11 and Firefox 145.0.2 on my desktop computer. Firefox is set as my default browser. Since the latest Firefox upgrade, the "Downsize/Minimize/Exit" toolbar does not appear upon opening and the only way I can close the program is to go to File<Exit, but I still have no way to downsize to share my screen with other applications. I sometimes have to open and close the program a couple of times before the Minimize toolbar appears. I already tried Firefox "Refresh" but the issue is still happening. </p>

I was just on a tech help support call and the tech person rebooted my firefox and lost my access to my most recent browsing history. Is there a way that I can still restore the lost history? It is not showing up in the History section anymore.
